Extended high-frequency hearing loss among Afro-Colombian adolescents from a rural area in Colombia: a cross-sectional study

OBJECTIVES

Research trends concerning hearing loss within teen rural populations are limited and current evidence suggests that extended high-frequency audiometry can be a sensitive tool to detect subclinical hearing loss. Moreover, current research emphasises the importance of representing different ethnic populations in science. This study aimed to determine the prevalence of acquired hearing loss through conventional pure-tone (0.25-8 kHz) and extended high frequency (EHF) (9-20 kHz) audiometry in Afro-Colombian adolescents from a rural area in Colombia.

DESIGN

Observational, cross-sectional study.

PARTICIPANTS

230 Afro-Colombian adolescents aged 13-17 years who attended high school in a rural population from Cartagena, Colombia.

INTERVENTIONS

Otoscopic examination, conventional (0.25-8 kHz) and EHF (9-20 kHz) audiometry tests were performed during February-March 2021. Sociodemographic and associated factor questionnaires were also applied to assess probable factors associated with EHF hearing loss.

MAIN OUTCOME MEASURES

Prevalence of acquired hearing loss using conventional and EHF audiometry, and factors associated with hearing loss.

RESULTS

Of 230 adolescents who met the eligibility criteria, 133 (57.82%) were female. The mean age was 15.22 years (SD: 1.62). The prevalence of hearing loss in at least one ear assessed with conventional audiometry was 21.30% and with EHF audiometry 14.78%. The main abnormal otoscopic findings included: neotympanum (1.30%), myringosclerosis (0.87%) and monomeric scars (0.43%). Factors associated with a higher probability of EHF hearing loss found through logistic regression were older age (prevalence ratio (PR): 1.45; 95% CI 1.16 to 1.80), attending the 'Picó' four or more times a month (PR: 6.63; 95% CI 2.16 to 20.30), attending bars more than three times a month (PR: 1.14; 95% CI 1.03 to 1.59) and self-reported hearing difficulties (PR: 1.24; 95% CI 1.22 to 4.05).

CONCLUSIONS

Our results suggest that acquired hearing loss is already widespread among this young rural population.

Learning from Tomorrow's Recyclers: Extension of Hands-on Recycled Waste Activity

We previously developed a plastic sorting activity for high school students. In that activity, several tools were provided to separate plastic waste materials based on their physical properties while considering the time and cost for each separation step. Here, we aimed to understand the impact of this activity on the awareness of and learning about plastic sorting in a younger age group (8 to 11 years old) and explored how parental involvement influenced students' interest in the topic. The activity was part of the STEM Zone Saturday program at the University of Houston. Pre- and post-evaluations were used to assess students' understanding of plastic sorting and overall experiences. While some insights into plastic sorting were derived from previous experiences, the activity improved awareness among students, particularly regarding sorting based on physical properties. The involvement of parents encouraged exploration, discovery, and enjoyment. These findings underscore the importance of early education and community engagement in fostering sustainable practices and advancing toward a circular economy.

Preparing the Next Generation for STEM: Adolescent Profiles Encompassing Math and Science Motivation and Interpersonal Skills and Their Associations With Identity and Belonging

Science, technology, engineering, and math (STEM) workers need both motivation and interpersonal skills in STEM disciplines. The aims of the study were to identify clusters of adolescents who vary in math and science motivation and interpersonal skills and to explore what factors are related to membership in a high math and science motivation and interpersonal skills cluster. Participants included 467 adolescents (312 female; Mage = 15.12 to SD = 1.71 year) recruited from out-of-school STEM programs in the US and UK. Findings from latent class analyses revealed four clusters, including a "High Math and Science Motivation and Interpersonal Skills" group, as well as groups that exhibited lower levels of either motivation or interpersonal skills. STEM program belonging, and STEM identity are related to membership in the high motivation and skills cluster. Findings provide insight into factors that may encourage motivation and interpersonal skills in adolescents, preparing them for STEM workforce entry.

Undergraduates’ pSTEM identity and motivation in relation to gender- and race-based perceived representation, stereotyped beliefs, and implicit associations

Women and underrepresented minoritized (URM) persons remain marginalized in physical science, technology, engineering, and math (pSTEM). Relative to non-URM men, URM women may experience a double disadvantage based on their gender and race whereby they observe few same-gender and few same-race role models in pSTEM while additionally internalizing stereotypes linking pSTEM with non-URM men. Our hypothesized model was partly supported in a sample of undergraduates ( N = 1,068; 68% women, 44% URM). First, perceiving same-gender or same-race pSTEM role models predicted lower explicit stereotypes among women and URM individuals regarding gender and race, respectively. Second, explicit and implicit associations linking pSTEM with men and White/Asian persons predicted (a) lower pSTEM identity among women and URM students and (b) higher identity among men and non-URM students. Finally, both implicit and explicit pSTEM identity positively predicted expectancy–value beliefs.

The Impact of the COVID-19 Lockdown on Parents and their Adolescent Children in Relation to Science Learning

With the transition to distance-learning at the beginning of the COVID-19 outbreak, several countries required parents and their children to remain at home, under lockdown. Many parents found themselves taking on additional responsibilities regarding their children's education. However, children do not always interpret their parents' intentions as they intended. This study investigated this complex relationship, showing that parents' emphases regarding science learning changed during the first COVID-19 lockdown and in parallel, the relations between these emphases and their adolescent children's goal orientation and self-efficacy toward science learning also changed. In 2019, one year before the COVID-19 lockdown, the children's mastery and performance orientations toward science, and their self-efficacy in science were significantly correlated with their parent's attitudes toward science. In 2020, shortly after the end of the first COVID-19 lockdown, these relations remained significant, but in addition the parents' emphasis on performance became a significant predictor of the children's mastery and performance orientations, and of their self-efficacy in science. A small increase in the children's performance orientation and self-efficacy in science was seen, and only a small decline in their mastery orientation toward science. These findings contrast with what the literature indicates is typical at this age, when there are no lockdown conditions.

The Core Concepts, Competencies, and Grand Challenges of Comparative Vertebrate Anatomy and Morphology

Core concepts offer coherence to the discourse of a scientific discipline and facilitate teaching by identifying large unifying themes that can be tailored to the level of the class and expertise of the instructor. This approach to teaching has been shown to encourage deeper learning that can be integrated across subdisciplines of biology and has been adopted by several other biology subdisciplines. However, Comparative Vertebrate Anatomy, although one of the oldest biological areas of study, has not had its core concepts identified. Here, we present five core concepts and seven competencies (skills) for Comparative Vertebrate Anatomy that came out of an iterative process of engagement with the broader community of vertebrate morphologists over a 3-year period. The core concepts are (A) evolution, (B) structure and function, (C) morphological development, (D) integration, and (E) human anatomy is the result of vertebrate evolution. The core competencies students should gain from the study of comparative vertebrate anatomy are (F) tree thinking, (G) observation, (H) dissection of specimens, (I) depiction of anatomy, (J) appreciation of the importance of natural history collections, (K) science communication, and (L) data integration. We offer a succinct description of each core concept and competency, examples of learning outcomes that could be used to assess teaching effectiveness, and examples of relevant resources for both instructors and students. Additionally, we pose a grand challenge to the community, arguing that the field of Comparative Vertebrate Anatomy needs to acknowledge racism, androcentrism, homophobia, genocide, slavery, and other influences in its history and address their lingering effects in order to move forward as a thriving discipline that is inclusive of all students and scientists and continues to generate unbiased knowledge for the betterment of humanity. Despite the rigorous process used to compile these core concepts and competencies, we anticipate that they will serve as a framework for an ongoing conversation that ensures Comparative Vertebrate Anatomy remains a relevant field in discovery, innovation, and training of future generations of scientists.

The Role of Community in Black Identity Development and Occupational Choice

Black Americans have historically been excluded from societal associations and faced wavering instability in their households, forcing them to work together for their individual and collective well-being. In past research, more than half of Black American students enrolled in school opted to pursue social or educational careers. Findings suggest that Black Americans’ occupational development is influenced by their family and community ties. In this conceptual paper, the foundation of the development of identity in African American culture is presented, as it relates to occupational decision-making. First, we discuss the influences of general identity development on occupational decision-making. Second, we argue that Black cultural identity is multidimensional, with strong community and family factors that play a special role in occupational choice. Third, we suggest future research paradigms to link racial identity, culture, and occupational choice among Black American students. By exploring the fundamental beliefs of Black cultural identity, and how they buffer against each other, Black American students will be better able to make occupational decisions.

Confronting repressive ideologies with critical pedagogy in science classrooms

The focus of this response to Arthur Galamba and Brian Matthews's 'Science education against the rise of fascist and authoritarian movements: towards the development of a Pedagogy for Democracy' is to underpin a critical pedagogy that can be used as a counterbalancing force against repressive ideologies within science classrooms. Locating science education within the traditions of critical pedagogy allows us to interrogate some of the historical, theoretical, and practical contradictions that have challenged the field, and to consider science learning as part of a wider struggle for social justice in education. My analysis draws specifically on the intellectual ideas of Paulo Freire, whose work continues to influence issues of theoretical, political, and pedagogical importance. A leading social thinker in educational practice, Freire rejected the dominant hegemonic view that classroom discourse is a neutral and value-free process removed from the juncture of cultural, historical, social, and political contexts. Freire's ideas offer several themes of relevance to this discussion, including his banking conception of education, dialog and conscientization, and teaching as a political activity. I attempt to show how these themes can be used to advance a more socially critical and democratic approach to science teaching.

Virology in the Classroom: Current Approaches and Challenges to Undergraduate- and Graduate-Level Virology Education

The pervasive effects of the current coronavirus disease 2019 pandemic are but one reason for educators to refocus their efforts on virology teaching. Additionally, it is critical to understand how viruses function and to elucidate the relationship between virus and host. An understanding of current virology education may improve pedagogical approaches for educating our students and trainees. Faculty who teach undergraduate microbiology indicate that approximately 10% of the course content features viruses; stand-alone virology courses are infrequently offered to undergraduates. Fortunately, virology taught to undergraduates includes foundational material; several approaches for delivery of lecture- and lab-based content exist. At the graduate education level, there is growing appreciation that an emphasis on logic, reasoning, inference, and statistics must be reintroduced into the curriculum to create a generation of scientists who have a greater capacity for creativity and innovation. Educators also need to remove barriers to student success, at all levels of education. Expected final online publication date for the Annual Review of Virology, Volume 8 is September 2021.

Who aspires to be a scientist/who is allowed in science? Science identity as a lens to exploring the political dimension of the nature of science

Our purpose in this paper is to put forward an argument about both the need and the value for understanding how the constructs of science identity and the nature of science (NOS) might intersect and intertwine and offer useful insights about science participation in times of crises. Based on our knowledge and understanding of these two research areas, we maintain that science identity research has not been fully engaged in understanding how perspectives on NOS might be intersecting with the questions of who can be (or not) a scientist and who is allowed (or not) in science. In this paper, we argue that the formation of a disrupting science identity that challenges existing constructed systems of power in science, requires robust understandings of NOS that place emphasis on the socially-produced narratives about science and scientists. In doing so, we engage with the following questions: (a) How have understandings of NOS contributed to conceptualizations of who can be a scientist and who is recognized as a scientist? (b) How have these conceptualizations contributed to producing exclusionary narratives and perpetuating inequalities in science? and, (c) How might an exploration of NOS through the lens of science identity be used to promote goals related to equity and social justice?

Entropy of Co-Enrolment Networks Reveal Disparities in High School STEM Participation

The current study uses a network analysis approach to explore the STEM pathways that students take through their final year of high school in Aotearoa New Zealand. By accessing individual-level microdata from New Zealand’s Integrated Data Infrastructure, we are able to create a co-enrolment network comprised of all STEM assessment standards taken by students in New Zealand between 2010 and 2016. We explore the structure of this co-enrolment network though use of community detection and a novel measure of entropy. We then investigate how network structure differs across sub-populations based on students’ sex, ethnicity, and the socio-economic-status (SES) of the high school they attended. Results show the structure of the STEM co-enrolment network differs across these sub-populations, and also changes over time. We find that, while female students were more likely to have been enrolled in life science standards, they were less well represented in physics, calculus, and vocational (e.g., agriculture, practical technology) standards. Our results also show that the enrollment patterns of Asian students had lower entropy, an observation that may be explained by increased enrolments in key science and mathematics standards. Through further investigation of differences in entropy across ethnic group and high school SES, we find that ethnic group differences in entropy are moderated by high school SES, such that sub-populations at higher SES schools had lower entropy. We also discuss these findings in the context of the New Zealand education system and policy changes that occurred between 2010 and 2016.

What science means to me: Understanding personal identification with (evolutionary) science using the sociology of (non)religion

Within science and technology studies, there is an established tradition of examining publics' knowledge of, trust in, access to and engagement with science, but less attention has been paid to whether and why publics identify with science. While this is understandable given the field's interest in bridging gaps between publics and producers of scientific knowledge, it leaves unanswered questions about how science forms part of people's worldviews and fits into cultural politics and conflict. Based on 123 interviews and 16 focus groups with mixed religious and nonreligious publics and scientists in the United Kingdom and Canada, this article utilises approaches from the sociology of (non)religion to delineate varieties of science identification. It maps out 'practical', 'norm-based', 'civilisational' and 'existential' identifications and explores how these interrelate with people's social characteristics. The article illustrates how science identification is typically dependent on a constellation of cultural/political influences rather than just emerging out of interest in science.

Welcoming Deaf Students into STEM: Recommendations for University Science Education

Scientists are shaped by their unique life experiences and bring these perspectives to their research. Diversity in life and cultural experiences among scientists, therefore, broadens research directions and, ultimately, scientific discoveries. Deaf individuals, for example, have successfully contributed their unique perspectives to scientific inquiry. However, deaf individuals still face challenges in university science education. Most deaf students in science, technology, engineering, and mathematics (STEM) disciplines interact with faculty who have little to no experience working with deaf individuals and who often have preconceptions or simply a lack of knowledge about deaf individuals. In addition to a lack of communication access, deaf students may also feel unwelcome in STEM, as do other underrepresented groups. In this essay, we review evidence from the literature and, where data are lacking, contribute the expert opinions of the authors, most of whom are deaf scientists themselves, to identify strategies to best support deaf students in university STEM education. We describe the journey of a hypothetical deaf student and methods for faculty to create a welcoming environment. We describe and provide recommendations for classroom seating and layout, accommodations, teaching strategies, and research mentoring. We also discuss the importance of including deaf scientists in research about deaf individuals.

On the Problem and Promise of Metaphor Use in Science and Science Communication

The language of science is largely metaphorical. Scientists rely on metaphor and analogy to make sense of scientific phenomena and communicate their findings to each other and to the public. Yet, despite their utility, metaphors can also constrain scientific reasoning, contribute to public misunderstandings, and, at times, inadvertently reinforce stereotypes and messages that undermine the goals of inclusive science. This paper 1) examines the generative potential of metaphors to the advancement of scientific knowledge and science communication, 2) highlights the ways in which outdated metaphors may limit scientific inquiry and contribute to public misunderstandings, and 3) critically analyzes the implications of cryptic social and political messages embedded in common metaphors in the life sciences.

The Construction of Physics as a Quintessentially Masculine Subject: Young People's Perceptions of Gender Issues in Access to Physics

The present article investigates explanations for gendered trends in Physics and Engineering access, reporting findings from a large-scale study funded by the UK Economic and Social Research Council and drawing primarily on data from interviews with 132 15–16 year-old adolescents and their parents. Survey results in our study and elsewhere show strong gender disparities in anticipated pursuit of Physics after completion of compulsory education. In order to explore the constructions of gender and Physics underlying these trends, we focus on qualitative interview data, applying Foucaultian analysis of discourse to investigate gendered narratives underpinning adolescents’ and their parents’ articulations. This analysis reveals three key discourses at work on the topic of women’s access to Physics: (a) equality of opportunity, (b) continued gender discrimination in and around Physics, and (c) Physics as quintessentially masculine. We additionally identify five distinct narratives supporting the discourse of physics as masculine. These various discourses and narratives are interrogated, and their implications explored. We conclude that it is only by disrupting prevalent constructions of the Physical sciences as a masculine and “hard” domain will we increase the presence of women in the sector. Working with young people to analyse and deconstruct the discursive assumptions made in relation to gender and Physics, as well as further work to increase accessibility and broaden representation in Physics, may be fruitful ways to challenge these longstanding associations between Physics and masculinity.
