This paper describes a gallery walk activity designed to help science students learn and practice strategies for making complex scientific concepts accessible to diverse audiences. The activity was implemented in a Science Communication course with 24 students from the Biotechnology and Food Technology programs. It introduces students to a range of rhetorical strategies, such as etymology, analogy, and personal storytelling, which are applied in exercises that encourage students to communicate scientific topics in engaging and relevant ways. The gallery walk encourages students to interact with eight stations, each focused on a specific communication strategy. By generating examples and discussing varied approaches, students may gain insights into adapting their communication for different contexts and audiences. The activity is a flexible and engaging approach to teaching science communication that may foster critical thinking and build students' confidence in applying communication techniques. Its adaptable format makes the gallery walk suitable for various classroom settings, supporting both large and small class sizes.</p>","PeriodicalId":46416,"journal":{"name":"Journal of Microbiology & Biology Education","volume":" ","pages":"e0020724"},"PeriodicalIF":1.6,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144044352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although bioinformatics is a critical sub-discipline of biology, it is not required in all biology degree programs. In parallel, there is a need to increase student access to research experiences. To address these needs, we offer a one-credit bioinformatics-focused and computational biology course-based undergraduate research experience (CURE), here called the CB-CURE. Preliminary data suggest the CB-CURE increased student interest, knowledge, and self-efficacy, but also reveal a shortage of access to undergraduate research experiences (UREs) in faculty labs at our large institution. To provide a more URE-like experience for a class setting, we developed a one-semester extension to the CB-CURE, called CURE+. In CURE+, students execute individual bioinformatics-driven research projects and obtain additional career development and mentoring. To evaluate CURE+, we measured students' bioinformatics and research self-efficacy, interest in bioinformatics and research, and emotions toward their project. Additionally, we evaluated student mastery of the CURE+ learning outcomes to determine if the experience successfully enabled students to develop their research skills. Our data show significant increases in (i) student self-efficacy in various bioinformatics and research skills and (ii) student interest in bioinformatics-related activities and in biomedical research. Students had positive emotions toward their research project, and a majority of students mastered the CURE+ learning outcomes. Our data suggest that an intensive CURE extension can provide a potentially transformative research experience that helps fill a void in access to research at institutions with a high student-to-faculty ratio.</p>","PeriodicalId":46416,"journal":{"name":"Journal of Microbiology & Biology Education","volume":" ","pages":"e0023124"},"PeriodicalIF":1.6,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144040927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explores the role of cultural wealth, as defined by Yosso's Community Cultural Wealth (CCW) framework, in shaping academic outcomes. Using data from 518 biology majors at a Hispanic-serving institution, we employed latent class analysis to identify distinct subgroups of students based on their cultural wealth profiles. Four latent classes emerged, characterized by varying levels of engagement across the CCW dimensions. Class 1 exhibited the highest cultural wealth but did not achieve the highest grades, highlighting the potential influence of unexamined mediators. Class 2, with moderate responses across dimensions, achieved the highest grades, suggesting a potential interaction of cultural wealth and external supports. Classes 3 and 4, with lower overall cultural wealth, exhibited lower academic performance. These findings reveal the complex interplay between cultural wealth and academic success in biology education.</p>","PeriodicalId":46416,"journal":{"name":"Journal of Microbiology & Biology Education","volume":" ","pages":"e0001225"},"PeriodicalIF":1.6,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143804441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While a short video describing the method and major results has already been widely used in the classroom setting, our case study connects details of the methods and results of the MEGA-plate experiment and antibiotic resistance to core biological concepts. The interrupted case study consists of four major parts: 1) an opening hook activity to capture students' attention and introduce the antibiotic crisis, 2) a jigsaw activity to research different classes of antibiotic targets and the resistance mechanisms that can arise, 3) a discussion of antibiotic resistance in real-time using the MEGA-plate experiment video, and 4) three different options for students to dive deeper into the experimental data from the MEGA-plate research article.

Through theory and practical examples, we consider the numerous ways in which power manifests both on and off the pages of the exams themselves, as well as ways in which power is consolidated away from students through logistical norms and tradeoffs. Centering the \"rules of the culture of power\" as delineated by Dr. Lisa Delpit, we reflect on exam practices that prioritize faculty voice and faculty convenience above student learning and student identity.

However, it is less clear how instructor-level variation in the implementation and timing of active learning activities affects student gains. Our study aims to investigate the extent to which the time spent on individual episodes of active learning activities influences student performance. We hypothesized that instructors who let students spend more time on peer discussion and individual thinking on practice problems associated with particular learning objectives would have better student exam scores on exam questions addressing those objectives. To test this hypothesis, we obtained a large data set of classroom recordings and student exam scores from an introductory biology course at a large 4-year university, where three instructors shared identical teaching materials and exams for different course offerings. Contrary to our hypothesis, although the three instructors spent significantly different amounts of time on episodes of thinking and peer discussion, there was no correlation between the total time spent on active learning activities and student performance on exam questions. Linear mixed-effects modeling of the effect of the length of episodes of student thinking and discussion on exam score found that in the context of shared instructional materials, the amount of course time spent on active learning activities did not reliably predict student performance on associated exam questions. This result held true even when only considering learning objectives with high variations in performance between offerings, difficult exam questions, or exam questions requiring higher-order thinking skills. Although our study was only conducted in one course, our results imply that time spent per individual episode of student thinking or peer discussion may not be the primary factor explaining the positive effects of active learning and that it may be worthwhile to explore other factors.</p>","PeriodicalId":46416,"journal":{"name":"Journal of Microbiology & Biology Education","volume":" ","pages":"e0007324"},"PeriodicalIF":1.6,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11636264/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142005517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For instance, the integration of inclusive teaching strategies like universal design for learning, growth mindset feedback, and the use of relatable role models in curricula may help increase the persistence, success, and self-efficacy of traditionally underrepresented groups in the sciences. Additionally, research indicates that training graduate TAs in evidence-based practices may have benefits beyond teaching efficacy, such as greater confidence in research preparedness and science communication-skills applicable to any scientific field or career path. Here, we developed and implemented an inclusive teaching series for a marine science department that included: (i) campus-wide pedagogical journal article discussions and knowledge-sharing, (ii) expert-led interactive workshops on evidence-based teaching strategies, and (iii) a graduate TA professional development module on inclusive lesson planning with opportunities to teach and receive feedback.
