Support Saves Lives: Exploring the Relationship Between Age of Transition, Family Support, and Retrospective K-12 Educational Experiences in Transgender Suicidality

Purpose

The purpose of this study is to test the association between protective and risk factors, including age of transition, K-12 experiences, and family support, on suicidality among transgender and gender nonbinary/gender queer (TNB) adults.

Methods

Our analysis relies on data from the 2015 United States Transgender Survey. We used separate logistic regression models to predict lifetime suicidal ideation and suicide attempt among 19,121 survey respondents.

Results

Negative K-12 experiences significantly predict higher likelihood of both suicidal ideation and suicide attempt for transgender people, regardless of age of transition, and after controlling for a host of covariates. The age a transgender person begins to live full time in a gender different from the one assigned at birth has little association with suicidality. However, supportive families act as a buffer against suicidal ideation, and unsupportive families significantly predict higher likelihood of suicide attempt for transgender people when controlling for numerous covariates.

Conclusion

Our findings underscore the importance of supportive environments for TNB adolescents. Interventions that strengthen interpersonal relationships and local environments will reduce suicidality among TNB youth. Importantly, recent anti-trans legislation may interfere with the ability of teachers and families to provide needed supports and will likely have deleterious effects on the mental health of TNB individuals.

Fish in a Dish: Using Zebrafish in Authentic Science Research Experiences for Under-represented High School Students from West Virginia

Early research experiences positively affect students' interest in STEM careers, and develop practical science and critical thinking skills. However, outreach opportunities are not equally accessible for all students. In states like West Virginia, where many students live in rural Appalachian communities, opportunities for engaging in STEM experiences are limited. In addition, rural teachers may not be equipped to provide authentic research experiences for students due to lack of resources or support. For many students in West Virginia, the Health Sciences and Technology Academy (HSTA) is a major opportunity for STEM engagement. Since its inception in 1998, HSTA has spread to 26 of 55 counties in West Virginia. The program recruits first-generation, low-socioeconomic status, rurally living, and African American high school students who are under-represented in STEM fields. Our research laboratory partnered with HSTA to implement an innovative, hands-on research camp using zebrafish for students participating in their annual junior-level biomedical sciences summer camp. Our camp was held in-person and adapted to an online format during the Covid-19 pandemic. We used pre-post surveys in both camps to assess impacts on science confidence and to collect information about general perceptions of zebrafish, research, and STEM fields. We found that students participating in the in-person and online camps experienced similar overall gains in science confidence. We also identified strong interest in zebrafish, research, and STEM degrees among online students. Online students did not prefer virtual learning experiences; however, they still enjoyed our camp. We also surveyed high school teachers volunteering for HSTA to identify factors that would encourage use of zebrafish in classrooms. The most prominent needs include classroom supplies, experience, and funding. Our successful science-education partnership demonstrates that zebrafish research experiences foster positive outcomes for under-represented students, and can inform future outreach efforts and collaborations with teachers.

Parental Involvement, Academic Self-Efficacy, and Depression on Academic Performance Among Chinese Students During COVID-19 Pandemic

Objective

This study was conducted to identify the factors (especially parental involvement, academic self-efficacy, and depression) associated with academic performance among Chinese K-12 students during the COVID-19 pandemic.

Methods

This cross-sectional study used data from the 2020 China Family Panel Studies (CFPS). The CFPS was conducted from July to December 2020 during the COVID-19 pandemic. A multistage probability sample proportional to size was used for the survey. The final sample consisted of 1747 K-12 students. This study used the 14-item Chinese Parental Involvement and Support Scale, the Responsibility Scale, and the 8-item Center for Epidemiologic Studies Depression Scale to measure parental involvement, academic self-efficacy, and depression, respectively. An ordered probit regression and structural equation models were employed to analyze the factors associated with academic performance. A multiple imputation technique was applied to compute missing values in selected variables.

Results

We found that parental involvement and academic self-efficacy were positively associated with good academic performance. In contrast, depression was negatively associated with good academic performance. Moreover, academic stress, male, rural residency, middle school, family size, high income, online gaming daily, reading, and intelligence quotient were statistically significant predictors on academic performance.

Conclusion

The empirical findings suggested that parental involvement and academic self-efficacy were positively and significantly associated with good academic performance. However, depression was negatively and significantly associated with good academic performance. These results showed that policymakers and practitioners can help improve academic success and address educational inequalities among K-12 students by implementing a series of reforms.

A critical systematic review of K-12 neurology/neuroscience pipeline programs

Background

Early exposure to neuroscience is imperative to strengthening the neuroscience and neurology pipeline and may present an avenue for increasing the number of practicing neurologists and diversifying the neuroscience workforce. Our objective was to systematically review existing K-12 neuroscience education and outreach programs to understand what educational programs have been developed and implemented.

Methods

We conducted an electronic database search of PubMed, EMBASE, PsycINFO, Education Source, and ERIC. All eligible articles were systematically reviewed to examine the type of program developed, target age group, implementation, and efficacy.

Results

Our search produced 2,574 results, from which 23 articles were deemed eligible. The breakdown by age group was as follows: 5 elementary school, 8 middle school, 8 high school, and 2 general K-12 range of students. Six articles described programs intended for URM students. All programs were found to be successful in exposing students to neuroscience and inspiring interest in pursuing a career in the field of neurology.

Discussion

Further efforts are necessary to analyze the long-term effectiveness of K-12 neuroscience education and outreach programs in overcoming the shortage of neurologists and explore the impact of mentorship for various age groups among K-12.Systematic review registrationhttps://doi.org/10.17605/OSF.IO/2G8CN.

Children, vaccines, and financial incentives

Recent studies have been analyzing and measuring the efficacy of the use of financial incentives to increase the Covid-19 vaccine uptake. To the best of our knowledge, this paper is the only study available in the literature that aims to measure the effect of financial incentives on vaccine rates among children. This paper explores the effects of a specific financial incentive on parents' vaccination decisions for their children. Using data from a regional practice, where students aged 12 and older received $50 gift cards per Covid-19 vaccination dose, we use various methodologies (synthetic control, linear regression, and difference-in-differences) to approximate the effects of financial incentives on vaccine rates. Our analysis reveals that gift cards increase vaccination rates by 2.64-4.23 percentage points from a baseline rate of 38 percent, concluding that financial incentives, in conjunction with other incentives and policies, can be considered to increase the rate of vaccines for 12- to 17-year-olds.

Competence and Stress of Medication Administration Practices for School Nurses in K-12 Taiwan Schools

We investigated school nurses' experiences, perceived government support, school nurses' acceptance of responsibility for medication administration, perceived stress, and perceived competence of medication administration and analyzed factors associated with perceived competence. In this cross-sectional study, from February to April 2023, we conducted an online survey of 269 school nurses serving at K-12 schools in Taiwan. The results revealed that although 71% of the participants had prior experience with medication administration, they reported low competence and high stress in areas such as drug interactions, adverse drug effects, and referrals. The school nurses' disagreement with responsibilities for medication administration emerged as the only factor to be significantly associated with perceived medication administration competence, accounting for 22.8% of the variance. We recommend implementing continuing training programs to provide school nurses with up-to-date medication information. Additionally, the development of practice guidelines is suggested as a means of enhancing nurses' competence and reducing their stress levels for the administration of medications.

Developing pre-service teachers' computational thinking: a systematic literature review

Recently, computational thinking (CT) has gained importance in education systems worldwide, specifically the CT training of pre-service teachers. This study conducted a systematic literature analysis (2011-2021) of 38 works on pre-service teachers' CT based on Web of Science, Science Direct, and Google Scholar databases. The results were as follows: (1) Six training methods were found, (2) CT training effectively improved pre-service teachers' CT, (3) A positive relationship was found between pre-service teachers' CT ability and the five factors affecting the ability, (4) A mode of training to improve CT ability of pre-service teachers and the relationship between CT ability and teaching methods were considered. This study suggested ideas for designing training modules of CT ability and a reference for realizing the best training effect. Finally, future research trends and a general model of training were presented as references for researchers, instructors, and policy makers to promote the CT of pre-service teachers.

The Turing Teacher: Identifying core attributes for AI learning in K-12

Introduction

Artificial intelligence in the educational domain has many uses; however, using AI specifically to enhance education and teaching in a K-12 environment poses the most significant challenges to its use. Beyond usage and application, the quality of the education is made even more arduous due to the dynamics of teaching primary and secondary school children, whose needs far exceed mere fact recollection. Utilizing prior research using AI in education and online education in the K-12 space, we explore some of the hurdles that AI applications face in K-12 teaching and provide core attributes for a "Turing Teacher," i.e., an AI powered technology for learning, specifically targeting the K-12 space.

Methods

Using a survey, which included qualitative responses during the implementation of online learning during the Covid Pandemic, we analyze the results using univariate and multivariate tests and analyzed the qualitative responses to create core attributes needed for AI powered teaching technology.

Results

The results present the challenges faced by any technology in an education setting and show that AI technology must help overcome negative feelings about technology in education. Further, the core attributes identified in the research must be addressed from the three stakeholder perspectives of teachers, parents and students.

Discussion

We present our findings and lay the groundwork for future research in the area of AI powered education. The Turing Teacher must be able to adapt and collaborate with real teachers and address the varying needs of students. In addition, we explore the use of AI technology as a means to close the digital divide in traditionally disadvantaged communities.

K-12 public schools in serving students with special education needs or underlying health conditions during the COVID-19 pandemic and strategies for improved accessibility

BACKGROUND

Students with special education needs or underlying health conditions have been disproportionately impacted (e.g., by reduced access to services) throughout the COVID-19 pandemic.

OBJECTIVE

This study describes challenges reported by schools in providing services and supports to students with special education needs or underlying health conditions and describes schools' use of accessible communication strategies for COVID-19 prevention.

METHODS

This study analyzes survey data from a nationally representative sample of U.S. K-12 public schools (n = 420, February-March 2022). Weighted prevalence estimates of challenges in serving students with special education needs or underlying health conditions and use of accessible communication strategies are presented. Differences by school locale (city/suburb vs. town/rural) are examined using chi-square tests.

RESULTS

The two most frequently reported school-based challenges were staff shortages (51.3%) and student compliance with prevention strategies (32.4%), and the two most frequently reported home-based challenges were the lack of learning partners at home (25.5%) and lack of digital literacy among students' families (21.4%). A minority of schools reported using accessible communications strategies for COVID-19 prevention efforts, such as low-literacy materials (7.3%) and transcripts that accompany podcasts or videos (6.7%). Town/rural schools were more likely to report non-existent or insufficient access to the internet at home and less likely to report use of certain accessible communication than city/suburb schools.

CONCLUSION

Schools might need additional supports to address challenges in serving students with special education needs or with underlying health conditions and improve use of accessible communication strategies for COVID-19 and other infectious disease prevention.

A Description of Suspected Concussions in Football-Related Activities among K-12 Students in Utah

The circumstances and nature of concussions among youth who play tackle, flag, or touch football are not well understood. This study used data from Utah's Student Injury Reporting System (SIRS) to explore suspected concussions among K-12 students sustained during participation in football-related activities (tackle, flag, or touch football). Descriptive statistics and chi-square analyses showed that 54.7% of suspected concussions due to football-related activity were among elementary and middle school and 41.3% were among high school students. Most suspected concussions resulted from being struck by or against something (81.9%) and occurred during school-sanctioned games and practices (37.9%), lunch, lunch recess, and recess (34.8%), or physical education class (22.7%). The type of school activity and context for suspected concussions varied by school level. School nurses and others in Utah may use study findings to customize concussion prevention efforts by school level and activity.

Impacts of digital technologies on education and factors influencing schools' digital capacity and transformation: A literature review

Digital technologies have brought changes to the nature and scope of education and led education systems worldwide to adopt strategies and policies for ICT integration. The latter brought about issues regarding the quality of teaching and learning with ICTs, especially concerning the understanding, adaptation, and design of the education systems in accordance with current technological trends. These issues were emphasized during the recent COVID-19 pandemic that accelerated the use of digital technologies in education, generating questions regarding digitalization in schools. Specifically, many schools demonstrated a lack of experience and low digital capacity, which resulted in widening gaps, inequalities, and learning losses. Such results have engendered the need for schools to learn and build upon the experience to enhance their digital capacity and preparedness, increase their digitalization levels, and achieve a successful digital transformation. Given that the integration of digital technologies is a complex and continuous process that impacts different actors within the school ecosystem, there is a need to show how these impacts are interconnected and identify the factors that can encourage an effective and efficient change in the school environments. For this purpose, we conducted a non-systematic literature review. The results of the literature review were organized thematically based on the evidence presented about the impact of digital technology on education and the factors that affect the schools' digital capacity and digital transformation. The findings suggest that ICT integration in schools impacts more than just students' performance; it affects several other school-related aspects and stakeholders, too. Furthermore, various factors affect the impact of digital technologies on education. These factors are interconnected and play a vital role in the digital transformation process. The study results shed light on how ICTs can positively contribute to the digital transformation of schools and which factors should be considered for schools to achieve effective and efficient change.

Linguistically Invisible: The Experiences of Transgender Students in Spanish Language Courses

More research is needed to understand the experiences of transgender students, including nonbinary students, in K-12 educational settings. Transgender students may experience unique stressors in World Language courses which impact their learning outcomes. In this study, three transgender adults in their twenties were interviewed about their experiences studying Spanish. Findings revealed that while binary transgender students may not feel language- and culture-specific stressors, nonbinary student identities may be rendered linguistically and culturally impossible. However, the impact on learning outcomes is ambiguous and may be mitigated by other factors and coping mechanisms. Implications for educators include increased awareness of transgender student experiences, including those specific to nonbinary students, and explicit efforts to queer the curriculum and provide opportunities for critical analysis and discussion. Additional research with larger and more diverse samples is needed to understand transgender student experiences, perceptions, and outcomes.

Queering the Common Core (and the NGSS): Challenging Normativity and Embracing Possibility

As guidelines for teacher practice, standards and benchmarks serve a strong normative purpose that can work counter to goals of equity and justice. In this project we applied queer theory's critique of normativity and concepts from queer pedagogy to the Common Core State Standards (CCSS) and the Next Generation Science Standards (NGSS). Using a collaborative qualitative approach, our research team explored and document how pre-service and practicing teachers addressed issues of learning modality, selection of diverse sources and texts, and applied the meanings of "queer" to suggest ways to disrupt traditional structures and modes of communication, in addition to including LGBTQ identities and gender and sexual diversity in their classes. We propose that queering the standards is an approach that acknowledges the material constraints that shape and characterize K-12 schools in the U.S., while also opening opportunities for teachers to engage in the crucial, intense, and necessary work to make schools sites that create rather than foreclose possibility.

Implementation of Test-to-Stay programming to minimize learning loss in a pre-K-8 school district

Objectives

Determine if a school-based Test-to-Stay (TTS) program designed to minimize learning loss reduced the incidence of COVID-19 in a US primary school district.

Study design

Observational, simple summary analysis of attendance and effectiveness of a TTS program implemented in a California school district.

Methods

Retrospective analysis of nested medical and demographic data. Survival curves were plotted using a cumulative hazard function to compare the probability of infection among close contacts exposed at school at different points of time between participants who participated in TTS versus those who did not participate in TTS. A Cox proportional hazards regression model with time-dependent covariates was used to estimate the association of TTS status with the incidence of SARS-CoV-2 infection.

Results

Univariate Cox regression analysis revealed that after adjustment, enrollment in TTS was negatively correlated with the risk of SARS-CoV-2 infection (hazard ratio 0.096; 95% confidence interval [CI], 0.024–0.390; P < 0.001).

Conclusions

TTS is an effective component of a layered protection strategy to prevent COVID-19 transmission in schools and communities, while minimizing the loss of in-person instruction in primary schools.

Effects of a gamified learning environment on students' achievement, motivations, and satisfaction

This paper aims to investigate the effects of a gamified e-learning environment on computer science learning for middle school students. An e-learning gamification environment was developed and implemented in 8th grade to examine its effects on improving learners' achievement, motivation, and satisfaction to learn computer science online. The study was conducted during the COVID-19 pandemic, where physical distancing was required, which made the conditions very suitable for achieving the goal of this study because teaching was conducted online through an e-learning platform. The effects of the online learning gamification environment were analyzed and interpreted. The pre-test-post-test control group design of the quasi-experiment was used. One hundred thirty-three students in 8th grade were involved in the study. Results indicated that the e-learning gamification environment increased students' motivation to learn computer science (α < 0.05) and their satisfaction with the online course (α < 0.05) but had no significant effect on their achievement. The study included several recommendations and suggestions for further studies.

Current trends in biopharmaceuticals production in Escherichia coli

Since the manufacture of the first biotech product for a fledgling biopharmaceutical industry in 1982, Escherichia coli, has played an important role in the industrial production of recombinant proteins. It is now 40 years since the introduction of Humulin® for the treatment of diabetes. E. coli remains an important production host, its use as a cell factory is well established and it has become the most popular expression platform particularly for non-glycosylated therapeutic proteins. A number of significant inherent obstacles in the use of prokaryotic expression systems to produce biologics has always restricted production. These include codon usage, the absence of post-translational modifications and proteolytic processing at the cell envelope. In this review, we reflect on the contribution that this model organism has made in the production of new biotech products for human medicine. This will include new advancements in the E. coli expression system to meet the biotechnology industry requirements, such as novel engineered strains to glycosylate heterologous proteins, add disulphide bonds and express complex proteins. The biopharmaceutical market is growing rapidly, with two production systems competing for market dominance: mammalian cells and microorganisms. In the past 10 years, with increased growth of antibody-based therapies, mammalian hosts particularly CHO cells have dominated. However, with new antibody like scaffolds and mimetics emerging as future proteins of interest, E. coli has again the opportunity to be the selected as the production system of choice.

Facilitating Systems Thinking Through Arts-Based STEM Integration

Engaging with socio-scientific issues often involves making sense of how - and for whom - actions, choices, and policies might affect aspects of daily life. Understanding the complexity of socio-scientific issues also requires recognizing the interconnectedness of - and working across - multiple communities and professions. We suggest that art, whether musical composition, illustrations, or sculpture / collage across materials would promote the synthesis of different types of knowledge across different scales and systems. The present investigation seeks to understand how arts integration into STEM curriculum could support systems thinking around socio-scientific issues, specifically around the issue of pathogen transmission in rural-agricultural communities. Our after-school program, which works with 3rd - 5th grade students in rural-agricultural communities, leverages the arts to promote systems-level understanding of zoonotic diseases and ecosystem dynamics. A total of 23 students across two sites located in rural communities in the Western United States participated in our afterschool program. We found that after completing the program students expanded their understanding of both the connections between concepts and an understanding of careers related to ecosystem dynamics. We suggest that educators can integrate both arts and sciences together to enhance systems thinking and expand student perception of the interconnectedness of STEM disciplines and their everyday lives.

Do Personality Traits Matter? Exploring Anti-drug Behavioral Patterns in a Computer-Assisted Situated Learning Environment

Drug abuse has been and continues to be, a common social issue worldwide, yet the efficiency of widely adopted sweeping speech for anti-drug campaigns has proven inefficient. To provide students with a safe and efficient learning situation related to drug refusal skills, we used a novel approach rooted in a serious learning game and concept map during a brief extracurricular period to help students understand drugs and their negative effects. The proposed game-based situational learning system allowed all students to participate simultaneously and individually in multiple scenarios of drug temptation posed by peers and classmates to practice responding and refusing drugs in school and community settings. Moreover, to explore whether different personality traits (such as the Big Five personality traits) result in different anti-drug responses, we used a serious game to conduct an anti-drug experiment on 53 junior middle school students aged 13–15. Each participant’s decision-making process was recorded in the serious game as behavioral patterns for lag sequential analysis (LSA). The outcomes revealed seven behavioral patterns including differentiation (D), acceptance (A), effective (ER) and ineffective responses (IR), effective (ES) and ineffective solution-seeking (IS), and failure to refuse (F). The GSEQ (Generalized Sequential Querier) which is a computer program for analyzing sequential observational data was used. The results indicated the following: (1) Neuroticism was performed at a relatively low level under the guidance of a concept map. (2) “Neuroticism” was associated with the lowest risk of accepting drugs. (3) Students with “openness to experiences” were at high risk of accepting drugs. (4) Almost all personality behavioral transition diagrams showed that failure to refuse (F) drugs was followed by inefficient seeking of help (SI) and inefficient refusal (RI). These findings provide reference points for designing adaptive anti-drug education programs.

Negotiating (dis-)engagement in K-12 blended learning

It is well-recognised that engagement is critical for learning and school success. Engagement (and disengagement) are, however, also influenced by context. Thus, as digital technologies add complexity to the educational context, they influence classroom leadership, lesson designs and related practices, and thereby engagement. Despite being critical, engagement and disengagement are not well explored concerning these influences, with a lack of research undertaken within socially disadvantaged schools. In this qualitative study, 14 classroom observations were conducted, during five months, in twelve classes in an upper secondary school in Sweden, along with dialogues with teachers (n=12) and students (n=32). The data were analysed using thematic analysis and descriptive statistics. Identified themes include digital context, teacher leadership, engagement and disengagement. A network of relations between the (dis-)engagement compound and themes is presented. The results identified processes in which engagement shifted into disengagement and vice versa; in particular, that the intention of active learning does not automatically translate to active learning for all students, although teachers employed a higher work pace than did their students. Teacher self-efficacy and awareness of how to manage digital technologies in and outside the classroom was found to play a vital role in facilitating engagement. Understanding the (dis-)engagement compound in blended learning environments is key to inform active and visible learning for future research and supportive organisational structures.

First and Second Order Barriers to Teaching in K-12 Online Learning

While an extensive literature base has focused on online learning, fewer studies have explored the unique implementation challenges in K-12 education. This case study addresses this gap by exploring how an urban, diverse school migrated to a fully online format through the lens of the first- and second-order barriers framework. In terms of first-order barriers, the study highlights the importance of (a) time needed to design and adapt instructional materials, (b) accountability within an online format, and (c) administrator support in the communication process. For second-order barriers, teachers commented on how they perceived online learning to impact important teaching activities (e.g., accountability, timeliness of feedback) and the teacher-student dynamic. Finally, they commented on the challenge to support the socio-emotional component of students and parents in online learning, which is important for school culture and community.

Preparing Teachers to Teach in K-12 Blended Environments: A Systematic Mapping Review of Research Trends, Impact, and Themes

Despite evidence concerning the widespread growth of K-12 blended teaching and the impact that emergency remote teaching during the COVID-19 pandemic has had on the spread of K-12 online and blended teaching, we could find no systematic reviews focused on preparing K-12 teachers for blended teaching. Previous literature reviews, such as those from Halverson et al. (2012) and Drysdale et al. (2013), have noted the lack of research focused on K-12 blended teaching contexts. This systematic mapping review (Grant & Booth, 2009) of 88 K-12 blended teacher preparation articles focused on identifying trends in author impact according to citation count and number of publications, journal impact according to number of publications, prevalence of research methods, and prevalence of research themes according to research questions and findings. The analysis provides a valuable snapshot of current literature, sets a foundation for a deeper thematic analysis of K-12 blended teacher preparation literature, and identifies some potential areas for future K-12 blended teaching research.

Technologies, Challenges and Needs of K-12 Teachers in the Transition to Distance Learning during the COVID-19 Pandemic

In response to the COVID-19 pandemic, K-12 schools in the United States closed and teachers transitioned to distance learning. The purpose of this survey research study is to determine technology resources and strategies K-12 teachers have used in this transition. Additionally, this study examines the difficulties teachers experienced, along with support they wish they had during the transition. Findings indicate that a wide variety of websites and applications were used to provide academic continuity, the majority of which were familiar to teachers. In the transition process, teachers were faced with various challenges, including difficulty engaging students and parents, a lack of school/district guidelines, and student Internet and computer access issues. Recommendations to prepare for future emergencies include making clear plans for emergencies and incorporating online components and training within current face-to-face classes and professional development.

A Differentiated Discussion About AI Education K-12

AI Education for K-12 and in particular AI literacy gained huge interest recently due to the significantly influence in daily life, society, and economy. In this paper we discuss this topic of early AI education along four dimensions: (1) formal versus informal education, (2) cooperation of researchers in AI and education, (3) the level of education, and (4) concepts and tools.

Visual tools for teaching machine learning in K-12: A ten-year systematic mapping

Teaching Machine Learning in school helps students to be better prepared for a society rapidly changing due to the impact of Artificial Intelligence. This requires age-appropriate tools that allow students to develop a comprehensive understanding of Machine Learning in order to become creators of smart solutions. Following the trend of visual languages for introducing algorithms and programming in K-12, we present a ten-year systematic mapping of emerging visual tools that support the teaching of Machine Learning at this educational stage and analyze the tools concerning their educational characteristics, support for the development of ML models as well as their deployment and how the tools have been developed and evaluated. As a result, we encountered 16 tools targeting students mostly as part of short duration extracurricular activities. Tools mainly support the interactive development of ML models for image recognition tasks using supervised learning covering basic steps of the ML process. Being integrated into popular block-based programming languages (primarily Scratch and App Inventor), they also support the deployment of the created ML models as part of games or mobile applications. Findings indicate that the tools can effectively leverage students' understanding of Machine Learning, however, further studies regarding the design of the tools concerning educational aspects are required to better guide their effective adoption in schools and their enhancement to support the learning process more comprehensively.

ICT-Supported Home-Based Learning in K-12: a Systematic Review of Research and Implementation

With the integration of technology in teaching and learning, online learning is not a new instructional strategy in the education landscape. However, the onset of the Covid-19 pandemic has necessitated the implementation of Home-based Learning (HBL) for educators, parents, and students on an unprecedented duration and scale. The notions and the factors associated with the implementation of HBL are yet fully investigated. As such, this study aims to shed light on the prerequisites needed for implementing HBL and suggest its future research direction. The methodology involves a systematic review of the existing studies on ICT-supported formal learning outside the classroom and to identify the prerequisites of HBL from various perspectives of the students, teachers, and parents. By doing so, this report will provide a deeper understanding of the multiple components of HBL and how it is to be taken into consideration when implementing HBL from both the theoretical and practical standpoint.

Three Decades of Research: The Case for Comprehensive Sex Education

PURPOSE

School-based sex education plays a vital role in the sexual health and well-being of young people. Little is known, however, about the effectiveness of efforts beyond pregnancy and sexually transmitted disease prevention. The authors conducted a systematic literature review of three decades of research on school-based programs to find evidence for the effectiveness of comprehensive sex education.

METHODS

Researchers searched the ERIC, PsycINFO, and MEDLINE. The research team identified papers meeting the systematic literature review criteria. Of 8,058 relevant articles, 218 met specific review criteria. More than 80% focused solely on pregnancy and disease prevention and were excluded, leaving 39. In the next phase, researchers expanded criteria to studies outside the U.S. to identify evidence reflecting the full range of topic areas. Eighty articles constituted the final review.

RESULTS

Outcomes include appreciation of sexual diversity, dating and intimate partner violence prevention, development of healthy relationships, prevention of child sex abuse, improved social/emotional learning, and increased media literacy. Substantial evidence supports sex education beginning in elementary school, that is scaffolded and of longer duration, as well as LGBTQ-inclusive education across the school curriculum and a social justice approach to healthy sexuality.

CONCLUSIONS

Review of the literature of the past three decades provides strong support for comprehensive sex education across a range of topics and grade levels. Results provide evidence for the effectiveness of approaches that address a broad definition of sexual health and take positive, affirming, inclusive approaches to human sexuality. Findings strengthen justification for the widespread adoption of the National Sex Education Standards.

School police officers' roles: The influence of social, developmental and historical contexts

Amid national protests over police brutality, debates over law enforcement in schools have been reignited. Though research has focused on the consequences of police presence in schools, few studies have investigated the roles of school police officers (SPOs) and whether the larger contexts influence them. Using a bioecological framework (Bronfenbrenner and Morris, 2006), we examined how historical, social and developmental contexts shape SPOs' views of their roles and the challenges and opportunities they encounter. Nineteen 90-min focus groups with 45 SPOs from one large school police department were conducted. Analysis revealed that SPOs perceived their roles as multifaceted, encompassing both formal (e.g., law enforcer, educator) and informal (e.g., confidante, counselor) roles. These roles were enacted differently depending on the school level and neighborhood context. Furthermore, the challenges and opportunities SPOs reported were also contextualized emerging from changes in school policies, the rise in technology and social media and increased professionalization of their police department. Implications for theory and research as well as for training and policy are discussed.

K-12 education in biochemistry and molecular biology: A parallel session at the IUBMB/PSBMB 2019 "Harnessing Interdisciplinary Education in Biochemistry and Molecular Biology" conference

Biochemistry and molecular biology education starts before our students get to university. From a very early age, they start learning informally about science beginning with the basics of science and as they progress through their school years they should be exposed to more advanced topics such as biochemistry and molecular biology. This session at the conference focused on three very different examples of engaging school students with biochemistry and molecular biology.

Adapting a Neural Engineering Summer Camp for High School Students to a Fully Online Experience

The COVID-19 pandemic and its resulting health and safety concerns caused the cancellation of many engineering education opportunities for high school students. To expose high school students to the field of neural engineering and encourage them to pursue academic pathways in biomedical engineering, the Center for Neurotechnology (CNT) at the University of Washington converted an in-person summer camp to a fully online program (Virtual REACH Program, VRP) offering both synchronous and asynchronous resources. The VRP is a five-day online program that focuses on a different daily theme (neuroscience, brain-computer interfaces, electrical stimulation, neuroethics, career/academic pathways). Each day, the VRP starts with a live videoconference meeting (lecture and interactive discussion) with a CNT faculty member. The online lectures are supported by at-home learning resources (e.g., text, videos, activities, quizzes) embedded within a digital book created using the Pressbook platform. An online bulletin board (Padlet) is also used by students to share artifacts and build community. Program evaluation will be conducted by an external evaluator. A summative survey will collect information on participants' experiences in the VRP and will help inform future iterations of the program. Although significant time was required to create a digital book, the VRP will reach a larger audience than the prior in-person program and resulted in the creation of learning tools that can be used in the future.

K-12 Health Education, Health Communication, and Health Literacy: Strategies to Improve Lifelong Health

To promote a health literate K-12 population, this chapter focuses on intersections of Health Literacy (HL), Health Education (HE) and Health Communication (HC) and urges collaborations among professionals from these disciplines as well as with stakeholders who share their interests and concerns. Core definitions and evolutionary highlights of these disciplines are presented, as well as their intersection and promise of impact on student academic and health outcomes. The Whole School, Whole Community, Whole Child (WSCC) model is used as an example of a framework embraced by education and health experts to help students become health literate. Internal and external stakeholders, models of what works, resources and strategies for developing or strengthening school health and health communication practice are presented. Selected contemporary threats to the social and emotional health and safety of youth are reviewed; as are successful, evidence-based, collaborative HE, HC, and HL programs and strategies. Finally, recommendations for future research and strategic actions in combining HE and HC for HL are discussed to empower, build resilience, and improve the lifelong health of children and adolescents as they become adults.

Parents' beliefs about and associations to their elementary children's home technology usage

This study sought to gather information through a survey of how newcomer parents' beliefs about technology usage and how they engage with technology as they support their children with twenty-first century literacies. Parent respondents (N = 70) were drawn from two publicly funded schools in the Niagara Region, Ontario, Canada, where the population tends to be immigrant, visible minority, with post-secondary education, but unemployed and low income. Descriptive statistics quantified daily technology activities as being communication-oriented with the majority of parents holding distinct beliefs about the amount and type of their children's technology usage. Chi-square tests indicated significant associations for demographic characteristics such as the gender, age, education, first language, and ethnicity of the parents as determinants of their beliefs about their children's technology usage (e.g., social media, mobile phones, television). As well, levels of access and use varied in terms of the number of new technologies and the types of literacy practices that families engage in. Immigrant parents might hold misconceptions about twenty-first century literacies, therefore there should be an attempt to assist them to provide responsive twenty-first century literacy and technology support for their children.

Evaluation of the St. Jude Cancer Education for Children Program on Cancer Risk Awareness, Attitudes, and Behavioral Intentions Among Fourth-Grade Science Students: Comparisons Between Racially Identifiable/High-Poverty Schools and Racially Diverse/Affluent Schools

The St. Jude Cancer Education for Children Program (SJCECP) aims to teach children about cancer and cancer control behaviors. During the 2012-2014 academic year, we conducted a pilot evaluation of the SJCECP curriculum to determine its impact on cancer risk awareness, attitudes, and behavioral intentions among fourth-grade students participating in the program. Nine local schools and 426 students from the Memphis area participated in the program evaluation. The results of this study show an increase in fourth-grade students' overall cancer risk factor awareness, attitudes, and behavioral intentions after participation in the intervention. The study also compared the mean change score for unaware students (e.g., those whose mean item score was < 3.5 on the pre-test) between students from racially identifiable/high-poverty schools (school group 1; six schools) and racially diverse/affluent schools (school group 2; three schools). Comparison of the mean change score for unaware students between school group 1 and school group 2 showed that increases in overall cancer risk factor awareness in school group 1 were higher than the increases of unaware students seen in school group 2; however, no differences between the changes in attitudes towards cancer risk factors and cancer control intentions and behaviors between the school groups were observed. We conclude that the SJCECP curriculum is successful in promoting cancer risk factor awareness, positive attitudes towards cancer risk factors, and increased cancer control intentions and behaviors among students at the fourth-grade level regardless of school demographics.

Engaging the Community through Science Nights: An Elementary School Case Study

Parental involvement increases K-12 student interest in STEM careers; however, when parents lack confidence in STEM content, or language and cultural barriers exist, parental engagement decreases. The Teacher Enrichment Initiatives (TEI) collects annual teacher feedback regarding the level of parental involvement with students during science nights, which laid the foundation for teachers to develop a science night training. Using qualitative methods, this single-case study follows elementary teachers who participated in the TEI science night training as they implement a Science Night program at a majority-minority elementary school. Data were gathered by TEI staff during the inaugural and third year of the Science Night program showing an increase in attendance from 700 (2016) to 800 (2018) and an increase in parental engagement with their student in STEM-related activities from 46% (2016) to 62% (2018). The data and follow-up summary were used by the case study school teachers to write and secure grants to support an annual Science Night program. This case study suggests Science Nights can be a mechanism to promote parental engagement with their student in hands-on STEM activities. Further, this case study suggests teacher feedback and inclusion in developing a science night model is central to successful implementation of a science night program.

An Institutional Coordinated Plan for Effective Partnerships to Achieve Health Equity and Biomedical Workforce Diversity

The rapid growth and accumulation of specialized knowledge in today's biomedical fields, combined with entrenched and emerging health issues that persist among certain groups within the US population, emphasizes the significant need to diversify the nation's biomedical science workforce. The under-representation of minorities in science results in inadequate scientific input from divergent social or cultural perspectives and detracts from our nation's ability to resolve health disparities. The University of North Texas Health Science Center at Fort Worth has developed a coordinated approach with local, regional, and national partners to increase participation of underrepresented students along the career pathway from K-12 to faculty level. Career stage specific activities that include research, mentoring, networking, career development, grantsmanship and health disparities curriculum are provided for participants. Successful outcomes from our coordinated plan includes an increase in participant self-efficacy, research presentation awards, increase in grant awards and publications, and career advancement. Through partnerships within our institution, local school districts, and minority serving institutions nationwide, our coordinated plan provides mutually beneficial co-learning experiences to increase the number of under-represented individuals entering translational research focused on increasing the biomedical research workforce diversity and achieving health equity.

Using Zebrafish to Bring Hands-On Laboratory Experiences to Urban Classrooms

Zebrafish are widely used as a model organism for research. Zebrafish embryos are also a useful resource for teaching students about vertebrate development. Here we describe a collaboration between two high school teachers and two university professors that used zebrafish to bring hands-on laboratory experiences to inner-city students, with the aim of increasing tangibility, and improving student understanding and retention, of several fundamental scientific concepts, such as the scientific method, cell division, mitosis, and Mendelian genetics. We describe and provide supporting material for each of the four laboratory modules that we developed. We also discuss the obstacles that we encountered and include suggestions of ways to overcome these. This collaboration provides an example of how high school teachers with very little zebrafish experience can gain the knowledge and confidence to develop and implement modules such as these in a relatively short period of time. Owing to the wide availability of zebrafish resources, these laboratories should provide a useful resource for other teachers who are interested in integrating more hands-on, inquiry-based investigations using live animals into their classes. We also hope to encourage other zebrafish researchers to collaborate with local teachers in similar projects.

Unveiling the Hybrid Genome Structure of Escherichia coli RR1 (HB101 RecA+)

There have been extensive genome sequencing studies for Escherichia coli strains, particularly for pathogenic isolates, because fast determination of pathogenic potential and/or drug resistance and their propagation routes is crucial. For laboratory E. coli strains, however, genome sequence information is limited except for several well-known strains. We determined the complete genome sequence of laboratory E. coli strain RR1 (HB101 RecA⁺), which has long been used as a general cloning host. A hybrid genome sequence of K-12 MG1655 and B BL21(DE3) was constructed based on the initial mapping of Illumina HiSeq reads to each reference, and iterative rounds of read mapping, variant detection, and consensus extraction were carried out. Finally, PCR and Sanger sequencing-based finishing were applied to resolve non-single nucleotide variant regions with aberrant read depths and breakpoints, most of them resulting from prophages and insertion sequence transpositions that are not present in the reference genome sequence. We found that 96.9% of the RR1 genome is derived from K-12, and identified exact crossover junctions between K-12 and B genomic fragments. However, because RR1 has experienced a series of genetic manipulations since branching from the common ancestor, it has a set of mutations different from those found in K-12 MG1655. As well as identifying all known genotypes of RR1 on the basis of genomic context, we found novel mutations. Our results extend current knowledge of the genotype of RR1 and its relatives, and provide insights into the pedigree, genomic background, and physiology of common laboratory strains.

Healthy Skin: Cancer Education for School Teachers and Nurses Using a "Train and Equip" Method

Skin cancer, especially malignant melanoma, continues on the increase. Different interventions are attempting to impact on this problem. The approach used by the Partners in Health Sciences program at the University of Arkansas for Medical Science is to both "train" and, importantly, "equip" classroom teachers and school nurses in a "Healthy Skin" professional development curriculum. Each participant not only received face-to-face interactive content training in a workshop setting that lasted 6 h; each also received a resource kit of supplies, materials, and equipment used in the workshop and designed for the trainee to use with students in a classroom/school setting. This single "hit" professional development event then can be replicated by each trainee annually for the span of her/his teaching/school-nursing career. A total of 588 trainees participated in "Healthy Skin" workshops that were held in 17 communities throughout the state. Participants attended from 188 different towns/cities. Of those in attendance, 511 (87 %) were females, 77 (13 %) males, 81 % Caucasian, 16 % African Americans, and the remaining 3 % self-identified as "other". There were 471 teachers, 85 nurses, and 32 "others" (administrators, school counselors). Trainees completed anonymous pre/post test measures with an increase in knowledge of 28.5 %. A short-term evaluation was conducted at the end of the workshop. After a minimum of 6 months had elapsed, a long-term evaluation was used to capture data on how the workshop experience transferred into new curricular/learning activities for the students of the workshop participants. There was a high level of satisfaction with the workshop experience and use of workshop content and resource kits. Our experiences in this type of professional development outreach provide a model of how institutions of higher education could contribute to the professional development of K-12 teachers and their students in any content area.

The functional landscape bound to the transcription factors of Escherichia coli K-12

Motivated by the experimental evidences accumulated in the last ten years and based on information deposited in RegulonDB, literature look up, and sequence analysis, we analyze the repertoire of 304 DNA-binding Transcription factors (TFs) in Escherichia coli K-12. These regulators were grouped in 78 evolutionary families and are regulating almost half of the total genes in this bacterium. In structural terms, 60% of TFs are composed by two-domains, 30% are monodomain, and 10% three- and four-structural domains. As previously noticed, the most abundant DNA-binding domain corresponds to the winged helix-turn-helix, with few alternative DNA-binding structures, resembling the hypothesis of successful protein structures with the emergence of new ones at low scales. In summary, we identified and described the characteristics associated to the DNA-binding TF in E. coli K-12. We also identified twelve functional modules based on a co-regulated gene matrix. Finally, diverse regulons were predicted based on direct associations between the TFs and potential regulated genes. This analysis should increase our knowledge about the gene regulation in the bacterium E. coli K-12, and provide more additional clues for comprehensive modelling of transcriptional regulatory networks in other bacteria.

K-12 Neuroscience Education Outreach Program: Interactive Activities for Educating Students about Neuroscience

The University of New England's Center for Excellence in the Neurosciences has developed a successful and growing K-12 outreach program that incorporates undergraduate and graduate/professional students. The program has several goals, including raising awareness about fundamental issues in neuroscience, supplementing science education in area schools and enhancing undergraduate and graduate/professional students' academic knowledge and skill set. The outreach curriculum is centered on core neuroscience themes including: Brain Safety, Neuroanatomy, Drugs of Abuse and Addiction, Neurological and Psychiatric Disorders, and Cognition and Brain Function. For each theme, lesson plans were developed based upon interactive, small-group activities. Additionally, we've organized our themes in a "Grow-up, Grow-out" approach. Grow-up refers to returning to a common theme, increasing in complexity as we revisit students from early elementary through high school. Grow-out refers to integrating other scientific fields into our lessons, such as the chemistry of addiction, the physics of brain injury and neuronal imaging. One of the more successful components of our program is our innovative team-based model of curriculum design. By creating a team of undergraduate, graduate/professional students and faculty, we create a unique multi-level mentoring opportunity that appears to be successful in enhancing undergraduate students' skills and knowledge. Preliminary assessments suggest that undergraduates believe they are enhancing their content knowledge and professional skills through our program. Additionally, we're having a significant, short-term impact on K-12 interest in science. Overall, our program appears to be enhancing the academic experience of our undergraduates and exciting K-12 students about the brain and science in general.
