Project description:We examined how the shift in learning environment from in-person to online classes, due to the COVID-19 pandemic, impacted three constructs of student engagement: behavioral engagement, including students' frequency of participating in class discussions, meeting with instructors, and studying with peers outside of class; cognitive engagement, including students' sense of belonging and self-efficacy; and emotional engagement, including students' attitudes toward science, their perceived value of the course, and their stress. Seventy-three undergraduate STEM students from across the country completed five-point Likert-style surveys in these areas of student engagement, both prior to their science course transitioning online and at the end of the spring 2020 semester. We found that while overall behavioral engagement did not change, students participated less frequently in class discussions but met with professors more often outside of class. We saw no significant change in cognitive engagement, indicating that while students' sense of belonging and self-efficacy ideally increases over the course of the semester, in this case, it did not. Most alarmingly, we found a significant decrease in emotional engagement, with students reporting a drastic decline in positive attitudes toward science. Students' reported stress levels remained unchanged, and students reported a slight increase in their perceived value of the science course they were taking. These data shed light on how the transition to online learning had an overall negative impact on undergraduate student engagement in science courses.

Project description:Numerous quantitative studies in science education found that student engagement declined after the onset of the COVID-19 pandemic, but analyses to identify the factors that drove emotional engagement down are lacking. Emotional engagement is a multidimensional construct composed of interest in an academic discipline, value in an academic course, and anxiety. Here, we use qualitative analysis to examine how and why the emergency shift from face-to-face to online classes during and after the pandemic-induced emergency remote transition impacted student emotional engagement. We coded student responses to open-ended questions using an emotional engagement framework and compared them between March and May 2020. Students' survey responses indicate that their positive attitudes toward science and value in the course declined. In contrast, more students expressed negative values of the course in the post-survey, with students mainly critiquing instructors and learning. This qualitative analysis offers a deeper understanding of students' emotional challenges during this educational upheaval and suggests effective teaching strategies for future crises.

Project description:The goal of our study was to track changes in student understanding of the central dogma of molecular biology before and after taking a genetics course. Concept maps require the ability to synthesize new information into existing knowledge frameworks, and so the hypothesis guiding this study was that student performance on concept maps reveals specific central dogma misconceptions gained, lost, and retained by students. Students in a genetics course completed pre- and posttest concept mapping tasks using terms related to the central dogma. Student maps increased in complexity and validity, indicating learning gains in both content and complexity of understanding. Changes in each of the 351 possible connections in the mapping task were tracked for each student. Our students did not retain much about the central dogma from their introductory biology courses, but they did move to more advanced levels of understanding by the end of the genetics course. The information they retained from their introductory courses focused on structural components (e.g., protein is made of amino acids) and not on overall mechanistic components (e.g., DNA comes before RNA, the ribosome makes protein). Students made the greatest gains in connections related to transcription, and they resolved the most prior misconceptions about translation. These concept-mapping tasks revealed that students are able to correct prior misconceptions about the central dogma during an intermediate-level genetics course. From these results, educators can design new classroom interventions to target those aspects of this foundational principle with which students have the most trouble.

Project description:MotivationE-learning is the standard solution adopted in transnational study programmes for which multiple face-to-face learning places are not an option. Bioinformatics is compatible with e-learning because its resource requirements are low. Online learning, however, is usually associated with high dropout rates because students start from a very low computational level and/or they need support to conduct practical analyses on their own.ResultsIn this article, we analyse the academic results of an online bioinformatics educational programme based on learning communities. The programme has been offered by the Spanish Pablo de Olavide University for more than 5 years with a completion rate of close to 90%. Learning bioinformatics requires technical and operational competencies that can only be acquired through a practical methodology. We have thus developed a student-centred and problem-based constructivist learning model; the model uses faculty and peer mentoring to drive individual work and retain students. Regarding our innovative learning model, the recruitment level (i.e. the number of applicants per available places and international origin), the results obtained (i.e. the retention index and learning outcomes) as well as the satisfaction index expressed by students and faculty lead us to regard this programme as a successful strategy for online graduate learning in bioinformatics.Availability and implementationAll data and results for this article are available in the figures and supplementary files.

Project description:Previous work has shown that students have persistent difficulties in understanding how central dogma processes can be affected by a stop codon mutation. To explore these difficulties, we modified two multiple-choice questions from the Genetics Concept Assessment into three open-ended questions that asked students to write about how a stop codon mutation potentially impacts replication, transcription, and translation. We then used computer-assisted lexical analysis combined with human scoring to categorize student responses. The lexical analysis models showed high agreement with human scoring, demonstrating that this approach can be successfully used to analyze large numbers of student written responses. The results of this analysis show that students' ideas about one process in the central dogma can affect their thinking about subsequent and previous processes, leading to mixed models of conceptual understanding.

Project description:In an introductory biology course, we implemented a learner-centered, model-based pedagogy that frequently engaged students in building conceptual models to explain how genes determine phenotypes. Model-building tasks were incorporated within case studies and aimed at eliciting students' understanding of 1) the origin of variation in a population and 2) how genes/alleles determine phenotypes. Guided by theory on hierarchical development of systems-thinking skills, we scaffolded instruction and assessment so that students would first focus on articulating isolated relationships between pairs of molecular genetics structures and then integrate these relationships into an explanatory network. We analyzed models students generated on two exams to assess whether students' learning of molecular genetics progressed along the theoretical hierarchical sequence of systems-thinking skills acquisition. With repeated practice, peer discussion, and instructor feedback over the course of the semester, students' models became more accurate, better contextualized, and more meaningful. At the end of the semester, however, more than 25% of students still struggled to describe phenotype as an output of protein function. We therefore recommend that 1) practices like modeling, which require connecting genes to phenotypes; and 2) well-developed case studies highlighting proteins and their functions, take center stage in molecular genetics instruction.

Project description:Student engagement in online learning enhance students performance and the outcomes of the learning process in online learning environment. The existed literature revealed various factors influencing student engagement in online leaning, however these studies were before the COVID-19 crisis. The purpose of the current paper is to explore the factors that influence student engagement in online learning during the COVID-19 crisis in middle school settings in developing countries where is a lack of studies about the factors influencing student's engagement in emergency remote learning during the crisis. A qualitative approach was used for data collection and analysis. Semi-structured interviews with 34 participants (14 students, 13 teachers, and 7 parents) were conducted for 20-30 min. Furthermore, online class observations were used for data collection; 13 online classes were observed. Each class was 40 min. A thematic analysis was used to categorize the findings into themes and subthemes. The findings of the study revealed that various factors influence student engagement in online learning during the crisis including infrastructure factors, cultural factors, digital inequality, and the threat to digital privacy. Cultural factors were the important factor that influences females because of parents' culture and their bias against females using online learning compared to male students. Teachers' presence and quality of content were the major factors that influence student engagement, where parental concerns, norms, and traditions emerged as the major factors in the crisis, influencing engagement. Most of the participants reported that teaching and learning online during the crisis has broadened the digital inequality and threatened their digital privacy which influenced negatively student engagement. The limitations of this research included the limited number of participants covering a large geographic area, and the research design using diverse and often limited educational software and delivery methods. Future studies could utilize a mixed-method approach and include more participants.Supplementary informationThe online version contains supplementary material available at 10.1007/s10639-021-10566-4.

Project description:Introduction United States medical schools continue to respond to student interest in global health (GH) and the evolution of the field through strengthening related curricula. The COVID-19 pandemic and superimposed racial justice movements exposed chasms in the US healthcare system. We sought to explore the possible relationship between the pandemic, US racial justice movements, and medical student interest in GH to inform future academic offerings that best meet student needs. Methods A novel, mixed-methods 30-question Qualtrics survey was disseminated twice (May-August 2021) through email and social media to all current students. Data underwent descriptive and thematic analysis. Results Twenty students who self-identified as interested in GH responded to the survey. Most (N = 13, 65%) were in preclinical training, and half were women (N = 10, 50%). Five (25%) selected GH definitions with paternalistic undertones, 11 (55%) defined GH as noncontingent on geography, and 12 (60%) said the pandemic and US racial justice movement altered their definitions to include themes of equity and racial justice. Eighteen (90%) became interested in GH before medical school through primarily volunteering (N = 8, 40%). Twelve (60%) students plan to incorporate GH into their careers. Conclusions Our survey showed most respondents entered medical school with GH interest. Nearly all endorsed a changed perspective since enrollment, with a paradigm shift toward equity and racial justice. Shifts were potentially accelerated by the global pandemic, which uncovered disparities at home and abroad. These results highlight the importance of faculty and curricula that address global needs and how this might critically impact medical students.
