Does exposure to research experiences have different learning outcomes than prior exposure to lab techniques in non-research settings?

A large body of literature has established the benefits of undergraduate research experiences via the traditional apprenticeship model. More recently, several studies have shown that many of these benefits can be recapitulated in course-based undergraduate research experiences (CUREs) that are more scalable and easier for students to participate in, compared to the apprenticeship-based research experiences. Many Biology curricula also incorporate more traditional laboratory courses, where students learn to use common laboratory techniques through guided exercises with known outcomes. Indeed, many programs across the nation provide such programs or courses for students early in their careers, with a view toward increasing student interest and engagement in Biology. While there is general consensus that all lab experiences have some benefits for students, very few studies have examined whether either research experiences or learning biological techniques in more traditional lab courses directly impacts student performance in lecture courses. Here, we show that prior familiarity with laboratory techniques does not improve student performance in a lecture course, even if these techniques are directly related to content being taught in the course. However, having prior research experience improves performance in the course, irrespective of whether the research experience included the use of course-related laboratory techniques.

An undergraduate genome research course using "big data"

The ability to analyze large data sets ("Big Data") is an increasingly important skill in modern science. In Biochemistry, the increased volume and velocity of data is particularly evident in the rapid expansion of biological databases. We present a modular bioinformatics course to survey the analysis of genomic data for advanced undergraduates. Research activities include genome scanning for endogenous retroviruses, annotating genomic sequences and a brief exploration of programming in R. A summative poster session was used to disseminate their work. This course is amenable to remote or online instruction. Supplemental materials provided include a schedule and outline. This article reports a session from the virtual international 2021 IUBMB/ASBMB workshop, "Teaching Science on Big Data."

Introducing climate change into the biochemistry and molecular biology curriculum

Our climate is changing due to anthropogenic emissions of greenhouse gases from the production and use of fossil fuels. Present atmospheric levels of CO₂ were last seen 3 million years ago, when planetary temperature sustained high Arctic camels. As scientists and educators, we should feel a professional responsibility to discuss major scientific issues like climate change, and its profound consequences for humanity, with students who look up to us for knowledge and leadership, and who will be most affected in the future. We offer simple to complex backgrounds and examples to enable and encourage biochemistry educators to routinely incorporate this most important topic into their classrooms.

Pandemic Teaching: Creating and teaching cell biology labs online during COVID-19

The year 2020 will forever be remembered as a season of pandemic teaching due to rising COVID-19 infections. Institutions of higher learning abruptly changed from in-person to online in attempts to minimize COVID-19 spread. Due to this, we created and taught online cell biology labs in response to the COVID-19 campus shutdown. Our virtual cell biology lab course emphasized molecular and cellular biology methods that can be used to study cells. Our report includes cell biology lab descriptions, learning outcomes, skills learned, lab set up and format, virtual tools used, lab sources, and lessons learned. We show how creative online lab alternatives can provide students valuable scientific learning experiences when in-person learning is not possible.

Flexible Implementation of the BASIL CURE

Course-based Undergraduate Research Experiences (CUREs) can be a very effective means to introduce a large number of students to research. CUREs are often an extension of the instructor's research, which may make them difficult to replicate in other settings because of differences in expertise or facilities. The BASIL (Biochemistry Authentic Scientific Inquiry Lab) CURE has evolved over the past 4 years as faculty members with different backgrounds, facilities, and campus cultures have all contributed to a robust curriculum focusing on enzyme function prediction that is suitable for implementation in a wide variety of academic settings. © 2019 International Union of Biochemistry and Molecular Biology, 47(5):498-505, 2019.

An expanded framework for biomolecular visualization in the classroom: Learning goals and competencies

A thorough understanding of the molecular biosciences requires the ability to visualize and manipulate molecules in order to interpret results or to generate hypotheses. While many instructors in biochemistry and molecular biology use visual representations, few indicate that they explicitly teach visual literacy. One reason is the need for a list of core content and competencies to guide a more deliberate instruction in visual literacy. We offer here the second stage in the development of one such resource for biomolecular three-dimensional visual literacy. We present this work with the goal of building a community for online resource development and use. In the first stage, overarching themes were identified and submitted to the biosciences community for comment: atomic geometry; alternate renderings; construction/annotation; het group recognition; molecular dynamics; molecular interactions; monomer recognition; symmetry/asymmetry recognition; structure-function relationships; structural model skepticism; and topology and connectivity. Herein, the overarching themes have been expanded to include a 12th theme (macromolecular assemblies), 27 learning goals, and more than 200 corresponding objectives, many of which cut across multiple overarching themes. The learning goals and objectives offered here provide educators with a framework on which to map the use of molecular visualization in their classrooms. In addition, the framework may also be used by biochemistry and molecular biology educators to identify gaps in coverage and drive the creation of new activities to improve visual literacy. This work represents the first attempt, to our knowledge, to catalog a comprehensive list of explicit learning goals and objectives in visual literacy. © 2016 by The International Union of Biochemistry and Molecular Biology, 45(1):69-75, 2017.

Vertical integration of biochemistry and clinical medicine using a near-peer learning model

Vertical integration has been extensively implemented across medical school curricula but has not been widely attempted in the field of biochemistry. We describe a novel curricular innovation in which a near-peer learning model was used to implement vertical integration in our medical school biochemistry course. Senior medical students developed and facilitated a case-based small group session for first year biochemistry students. Students were surveyed before and after the session on their attitudes about biochemistry, as well as the effectiveness of the session. Prior to the session, the students believed biochemistry was more important to understanding the basic science of medicine than it was to understanding clinical medicine or becoming a good physician. The session improved students' attitudes about the importance of biochemistry in clinical medicine, and after the session they now believe that understanding biochemistry is equally important to the basic sciences as clinical medicine. Students would like more sessions and believe the senior student facilitators were knowledgeable and effective teachers. The facilitators believe they improved their teaching skills. This novel combination of near-peer learning and vertical integration in biochemistry provided great benefit to both first year and senior medical students, and can serve as a model for other institutions. © 2016 by The International Union of Biochemistry and Molecular Biology, 44(6):507-516, 2016.

Introducing chemical biology applications to introductory organic chemistry students using series of weekly assignments

Calls to bring interdisciplinary content and examples into introductory science courses have increased, yet strategies that involve course restructuring often suffer from the need for a significant faculty commitment to motivate change. Minimizing the need for dramatic course reorganization, the structure, reactivity, and chemical biology applications of classes of biological monomers and polymers have been integrated into introductory organic chemistry courses through three series of semester-long weekly assignments that explored (a) Carbohydrates and Oligosaccharides, (b) Amino Acids, Peptides, and Proteins, and (c) Nucleosides, Nucleotides, and Nucleic Acids. Comparisons of unannounced pre- and post tests revealed improved understanding of a reaction introduced in the assignments, and course examinations evaluated cumulative assignment topics. Course surveys revealed that demonstrating biologically relevant applications consistently throughout the semesters enhanced student interest in the connection between basic organic chemistry content and its application to new and unfamiliar bio-related examples. Covering basic material related to these classes of molecules outside of the classroom opened lecture time to allow the instructor to further build on information developed through the weekly assignments, teaching advanced topics and applications typically not covered in an introductory organic chemistry lecture course. Assignments were implemented as homework, either with or without accompanying discussion, in both laboratory and lecture organic courses within the context of the existing course structures.

Bringing research into a first semester organic chemistry laboratory with the multistep synthesis of carbohydrate-based HIV inhibitor mimics

Benefits of incorporating research experiences into laboratory courses have been well documented, yet examples of research projects designed for the first semester introductory organic chemistry lab course are extremely rare. To address this deficiency, a Carbohydrate-Based human immunodeficiency virus (HIV) Inhibitor project consisting of a synthetic scheme of four reactions was developed for and implemented in the first semester organic lab. Students carried out the synthetic reactions during the last 6 of 10 total labs in the course, generating carbohydrate-based dimeric target molecules modeled after published dimers with application in HIV therapy. The project was designed to provide a research experience through use of literature procedures for reactions performed, exploration of variation in linker length in the target structure, and synthesis of compounds not previously reported in the scientific literature. Project assessment revealed strong student support, indicating enhanced engagement and interest in the course as a direct result of the use of scientific literature and the applications of the synthesized carbohydrate-based molecules. Regardless of discussed challenges in designing a research project for the first semester lab course, the finding from data analysis that a project implemented in the first semester lab had significantly greater student impact than a second semester project should provide motivation for development of additional research projects for a first semester organic course.

Guided inquiry activities for learning about the macro- and micronutrients in introductory nutrition courses

Most students enroll in general education introductory nutrition classes because they want to improve their diets in order to lose weight or enhance athletic performance. These nonscience majors are often less interested in learning about the fundamental biochemical principles underlying nutrition or are surprised that this foundational knowledge of biochemistry is essential for appropriate diet planning. Furthermore, nonscience majors sometimes find traditional, lecture-oriented science classes that encourage competition rather than collaboration to be uninviting and unappealing. For these reasons, we have developed a set of guided inquiry activities about macronutrients (carbohydrates, lipids, and proteins) and micronutrients (vitamins and minerals) for use in introductory nutrition courses for nonscience majors. In our first study (Spring 2012), we divided students into two groups with two different approaches for learning about the macronutrients: (1) a traditional, lecture-based approach and (2) an active learning approach with guided inquiry activities. We showed through the use of embedded common exam questions that students mastered concepts related to the macronutrients equally well using either approach. Due to positive student and faculty feedback from the first study, we decided to have all students use the guided inquiry approach in a subsequent study the following year (Spring 2013). In our second study we used pre/post survey data to evaluate both students' concept mastery and confidence in answering questions about the macro- and micronutrients. We found that (1) students showed gains in both concept mastery and confidence and (2) as students' confidence increased, post-test concept scores also increased.

"On the job" learning: A bioinformatics course incorporating undergraduates in actual research projects and manuscript submissions

The sequencing of whole genomes and the analysis of genetic information continues to fundamentally change biological and medical research. Unfortunately, the people best suited to interpret this data (biologically trained researchers) are commonly discouraged by their own perceived computational limitations. To address this, we developed a course to help alleviate this constraint. Remarkably, in addition to equipping our undergraduates with an informatic toolset, we found our course design helped prepare our students for collaborative research careers in unexpected ways. Instead of simply offering a traditional lecture- or laboratory-based course, we chose a guided inquiry method, where an instructor-selected research question is examined by students in a collaborative analysis with students contributing to experimental design, data collection, and manuscript reporting. While students learn the skills needed to conduct bioinformatic research throughout all sections of the course, importantly, students also gain experience in working as a team and develop important communication skills through working with their partner and the class as a whole, and by contributing to an original research article. Remarkably, in its first three semesters, this novel computational genetics course has generated 45 undergraduate authorships across three peer-reviewed articles. More importantly, the students that took this course acquired a positive research experience, newfound informatics technical proficiency, unprecedented familiarity with manuscript preparation, and an earned sense of achievement. Although this course deals with analyses of genetic systems, we suggest the basic concept of integrating actual research projects into a 16-week undergraduate course could be applied to numerous other research-active academic fields.

Curriculum and course materials for a forensic DNA biology course

The Forensic Science Education Programs Accreditation Commission (FEPAC) requires accredited programs offer a "coherent curriculum" to ensure each student gains a "thorough grounding of the natural…sciences." Part of this curriculum includes completion of a minimum of 15 semester-hours forensic science coursework, nine of which can involve a class in forensic DNA biology. Departments that have obtained or are pursuing FEPAC accreditation can meet this requirement by offering a stand-alone forensic DNA biology course; however, materials necessary to instruct students are often homegrown and not standardized; in addition, until recently, the community lacked commercially available books, lab manuals, and teaching materials, and many of the best pedagogical resources were scattered across various peer-reviewed journals. The curriculum discussed below is an attempt to synthesize this disparate information, and although certainly not the only acceptable methodology, the below discussion represents "a way" for synthesizing and aggregating this information into a cohesive, comprehensive whole.
