Self-selecting peer groups formed within the laboratory environment have a lasting effect on individual student attainment and working practices.
Within the present study, we investigate the lasting effect of laboratory peer group interactions on the end of year attainment of bioscience and chemistry students. By asking students to identify who they primarily work with within the laboratory environment and evaluating the interactions through cluster analysis, we identified two main categories of laboratory peer groups. The first long-lived well-established pairings of two students, "swans", who work together for all or the majority of the laboratory sessions and the second dynamic fluid groups, "dolphins", of between three to nine students who work with each other interchangeably. Statistical analysis is presented, which demonstrates that individuals within each lab peer group were likely to achieve a similar average mark at the end of the first year of study on the course. We identified the driving factors for the formation of these groups as friendship and perceived work ethic. There is a preference for high achieving students to work with other high achieving students and lower-achieving to group around a shared social background. Targeted interventions, in which pairings were selected by the tutor at the onset of the study, altered the ratio from long-lived pairs to more dynamic groups and increased students willingness to work with others outside of their group but did not change the drivers of group formation or resulting pattern of achievement. We conclude with recommendations around group working within the laboratory environment
Building bacterial knowledge: Games as teaching aides for higher-order thinking skills
Bacteria Builder is a videogame designed to teach student nurses about bacterial form and function within the context of a university fundamental science module. It challenges players to design and build bacteria with appropriate structures for surviving in different environments. This paper describes two studies undertaken to explore the most effective way to use the game as part of teaching on the module. 152 student nurses took part in the first evaluation, which used a control group to compare learning gains for a) only the game b) only the lecture and c) the game plus a reflective activity. All three conditions demonstrated improvements over the control, but there were no significant differences in learning gains between the experimental conditions. In a second evaluation, 124 student nurses took part in a study which compared the lecture on its own to the lecture and game together. Learning gains were found to be over 50% higher in the lecture and game condition, and subsequent analysis showed that the nurses who had played the game made greater improvements in questions designed to test higher-order thinking skills.
The design and motivation behind the Bacteria Builder game is described and the results of these studies are discussed with respect to the role of teaching in maximising the effectiveness of game-based learning. Correlations between interaction data for different parts of the game are explored with respect to learning outcomes, and implications for the design of future studies are discussed
Redefining online biology education: a study on interactive branched video utilisation and student learning experiences
This study evaluated the use of interactive, branched videos compared with traditional passive linear delivery for enhancing student engagement and learning in online courses. Undergraduate biology students were provided with either branched decisionâbased or linear videos on cell biology and protein purification as selfâguided or consolidation activities. While the interactive branched videos did not improve learning gains, thematic analysis revealed that students found them more enjoyable and preferable for revision. However, most students felt linear passive videos were more logically structured for core content delivery. In a revised format, with clearer scaffolding, the interactive branched videos were perceived as significantly more engaging and useful when utilised for a problemâsolving activity. Students welcomed the autonomy of directing their learning path but desired support to avoid missing critical information. Overall, thoughtfully designed branched videos can increase student motivation, but their utility depends on context. Our findings indicate the importance of balancing interactivity, clear organisation and purpose when incorporating these innovative formats into online learning. Branched videos show promise for increasing engagement but require intentional instructional design tailored to learning objectives
Family-focused campus-based university event increases perceived knowledge, science capital and aspirations across a wide demographic
Creative ways of delivering informal science events in community settings are viewed as key to engaging new audiences and participants whom scientists find hard to reach, however, the impact of âformalâ setting events is often overlooked. Here, through a mixed-methods approach, we analyse a large-scale family-focused public engagement event hosted within a university campus setting. We aimed to explore the profile of visitors attending together with the impact and perceived knowledge gained. Analysis from two consecutive years of data collection found that the university-based event attracted new visitors annually, with almost half having not attended other science events/attractions within the last year. An increase in perceived knowledge was shown amongst all study participants, being significantly amplified in those from low progression to higher education postcode areas. Both immediate and longer-term positive impact was reported by participants with increases in components of science capital observed as well as enhanced positive perception of the university and its students. This data exemplifies the benefit of university-hosted events in widening participation and public understanding of science
Identification of new members of the Escherichia coli K-12 MG1655 SlyA regulon.
SlyA is a member of the MarR family of bacterial transcriptional regulators. Previously, SlyA has been shown to directly regulate only two operons in Escherichia coli K-12 MG1655, fimB and hlyE (clyA). In both cases SlyA activates gene expression by antagonizing repression by the nucleoid associated protein H-NS. Here the transcript profiles of aerobic glucose-limited steady-state chemostat cultures of E. coli K-12 MG1655, slyA mutant and slyA over-expression strains are reported. The transcript profile of the slyA mutant was not significantly different to that of the parent; however, that of the slyA expression strain was significantly different from that of the vector control. Transcripts representing 27 operons were increased in abundance, whereas 3 were decreased. Of the 30 differentially regulated operons, 24 have been previously associated with sites of H-NS binding, suggesting that antagonism of H-NS repression is a common feature of SlyA-mediated transcription regulation. Direct binding of SlyA to DNA located upstream of a selection of these targets permitted the identification of new operons likely to be directly regulated by SlyA. Transcripts of four operons coding for cryptic adhesins exhibited enhanced expression and this was consistent with enhanced biofilm formation associated with the SlyA over-producing strain
How studentsâ inspirations and aspirations impact motivation and engagement in the first year of study
Within this study, we aim to better understand the inspirations and aspirations of first year Biosciences and Chemistry undergraduates, how these change over the first year of study and their impact on motivation and engagement. Participants were asked to write a short reflective piece at the start of Welcome Week in their first year of undergraduate study. Thematic analysis identified four themes surrounding inspirations and aspirations. The most common theme was students naming a specific career as their aspiration (58%), followed by being inspired by work experience, aspiring to undertake further study and finally personal experience of a specific illness. Our findings showed that studentsâ career aspirations differed depending on ethnicity, with ambitions for medicine and laboratory work showing a marked increase in some ethnically marginalised groups. Focus groups undertaken at the end of the first year of study highlight increased motivation and engagement when students feel their course content aligns with their career aims. Conversely, students are disengaged by course material they feel is irrelevant to their chosen career. Here, we will discuss the impact of these findings on creating an inclusive curriculum and the career readiness of the student body. Conclusions apply to career development modules and how the applied nature of a course can lead to engagement and higher motivation for students as well as curriculum design
Reflections on the teaching symposium at the Microbiology Society Annual Conference 2023
The Microbiology Society Education and Outreach Network (EON) recently hosted the Teaching Symposium at the Microbiology Society Annual Conference, sponsored by Access Microbiology. The presence of the Symposium as an established parallel session within the wider Annual Conference reflects the importance of high-quality, contemporary microbiology education and outreach delivered in an enthusiastic and inclusive manner. At the 2023 Symposium, a variety of pedagogical research projects in higher education learning, teaching and assessment, as well as public engagement projects, were showcased through invited talks, offered talks, flash talks and posters. The event was attended by up to 70 delegates. Several themes were noted throughout the day: engaging with Gen Z (Generation Z, those born between 1996 and 2010), active learning, art in science and engaging with non-higher education (HE) audiences. Inclusivity was a key driver in the organization of the Symposium; the room was set up to encourage discussion and participants could ask questions using an online platform as well as speaking in the room. We now encourage all speakers to consider publishing their work as a peer-reviewed article for further dissemination and impact
Cooking and Meal Planning as Predictors of Fruit and Vegetable Intake and BMI in First-Year College Students
The objective was to determine if cooking skills and meal planning behaviors are associated with greater fruit and vegetable intake and lower body mass index (BMI) in first-year college students who are at risk for excessive weight gain. A cross-sectional analysis was conducted using baseline data from a multi-state research project aimed at preventing weight gain in first-year college students. Cooking type, frequency and confidence, self-instruction for healthful mealtime behavior intention, self-regulation of healthful mealtime behavior, and cup equivalents of fruits and vegetables (FV) were measured using validated surveys. BMI was calculated from measured height and weight. First-year students (n = 1108) considered at risk for weight gain from eight universities completed baseline assessments within the first month of entering college. Multiple linear regression was used to determine associations among independent variables of cooking patterns, meal planning behaviors, and dependent variables of fruit and vegetable intake and BMI, after controlling for the influence of sex. Cooking more frequently, cooking with greater skills, and practicing meal planning behaviors are associated with greater fruit and vegetable intake and lower BMI in first-year college students. Interventions aimed at improving health in college students may be enhanced by incorporating cooking and meal planning components
University student-led public engagement event: increasing audience diversity and impact in a non-science space
There is a wealth of innovation in microbiology outreach events globally, including in the setting where the public engagement is hosted. Previous data indicate an underrepresentation of marginalized ethnic groups attending UK science-based public engagement events. This project engaged our student cohort, encompassing a diverse range of ethnic groups, to create an integrated art and science event within an existing series of adult education evenings. The studyâs objectives were to increase the proportion of visitors from marginalized ethnic groups and to gain a greater understanding of the impact of the event on the visitorsâ reported science capital. The participantsâ demographics, links to our students and University, and detailed impact on participantsâ science capital of the event were determined through analysis of exit questionnaires. There was an increase in the proportion of marginalized ethnic group visitors compared to similar previous events. A higher proportion of visitors from marginalized ethnic groups had links with our students and University compared to white/white British visitors. Elements of the exit questionnaire were mapped to the science capital framework and participantsâ science capital was determined. Both ethnically marginalized participants and white/white British visitors showed an increase in science capital, specifically dimensions of science-related social capital and science-related cultural capital, after the event. In conclusion, our study suggests that a student-led blended art and science public engagement can increase the ethnic diversity of those attending and can contribute towards creating more inclusive public engagement events.</jats:p
Overcoming roadblocks in the development of vaccines for leishmaniasis
INTRODUCTION: The leishmaniases represent a group of parasitic diseases caused by infection with one of several species of Leishmania parasites. Disease presentation varies because of differences in parasite and host genetics and may be influenced by additional factors such as host nutritional status or co-infection. Studies in experimental models of Leishmania infection, vaccination of companion animals and human epidemiological data suggest that many forms of leishmaniasis could be prevented by vaccination, but no vaccines are currently available for human use. AREAS COVERED: We describe some of the existing roadblocks to the development and implementation of an effective leishmaniasis vaccine, based on a review of recent literature found on PubMed, BioRxiv and MedRxiv. In addition to discussing scientific unknowns that hinder vaccine candidate identification and selection, we explore gaps in knowledge regarding the commercial and public health value propositions underpinning vaccine development and provide a route map for future research and advocacy. EXPERT OPINION: Despite significant progress, leishmaniasis vaccine development remains hindered by significant gaps in understanding that span the vaccine development pipeline. Increased coordination and adoption of a more holistic view to vaccine development will be required to ensure more rapid progress in the years ahead
