Using Virtual Simulations in Online Laboratory Instruction and Active Learning Exercises as a Response to Instructional Challenges during COVID-19.

ABSTRACT: The onset of the COVID-19 pandemic in the spring of 2020 thrust instructors into a world of frenzy, presenting unique challenges to delivering course content. A particular challenge was determining suitable substitutes for wet lab experiments that are often comprised in science labs. Recognizing that this problem was not short-term, I started to look into virtual substitutions to be implemented in the 2020-2021 academic year. Virtual simulations can replace labs, be incorporated as pre-lab assignments, or used as active-learning or experiential learning exercises in a traditional classroom setting while providing low-cost, safe, and acceptable solutions to the current problem. Virtual simulations were examined on different platforms, including Labster, McGraw Hill Connect Virtual Labs, HHMI BioInteractive, Learn.Genetics, Virtual Interactive Bacteriology Laboratory, and Biology Corner. The goal was to provide faculty around the world with a reference list of virtual simulations that are aligned to specific AAAS and ASM student learning outcomes. These simulations are discussed in terms of content, features, and advantages of use. A list of lab exercises aligned to biology courses (microbiology, genetics, and cell biology) is also provided.

Project description:Studies have demonstrated students' resistance to active learning, despite evidence illustrating that their learning is improved relative to students in lectures. Specifically, while active learning and group work are effective at engaging students in their learning process, studies report that students' perceptions of active learning approaches are not always positive. What remains underexplored is whether students' perceptions of active learning improve with effective instructor facilitation and whether there exists differential perceptions between racially minoritized students and represented students. Here, we estimate students' perceptions of effective instructor facilitation as the mediator in the relationship between active learning and perceptions of learning and perceived utility for class activities (task value). Then, we examine differences by racial identification. We collected classroom observation data to empirically categorize courses as active learning or lecture-based and surveyed 4,257 college students across 25 STEM classrooms at a research-intensive university. We first examined the relationship between active learning on student perceptions and found a negative relationship between active learning and perceptions of learning and task value for both racially minoritized students and represented students. Next, we assessed whether students' perceptions of instructor effectiveness in facilitating group activities mediate these negative relationships. We found that, on average, students of all races were more likely to positively perceive instructor facilitation in active learning classes relative to lectures. In turn, the positive perceptions of instructor facilitation partially suppressed the negative relationship between active learning and perceptions of learning and task value. These results demonstrate that effective instructor facilitation can influence both students' self-assessment of learning and perceived utility of the learning activities, and underscores the importance of developing pedagogical competence among college instructors.
