ABSTRACT: In this era of information abundance and digital connectivity, educational videos are a transformative and widely used resource in STEM higher education. Much of what is known about the effective use of educational videos comes from analyzing videos used for content delivery and the impacts on knowledge gains or behavioral engagement with videos. Less is known about how videos may impact students’ affective learning experiences, feelings, and attitudes or how to effectively use videos in science education beyond just as a content-delivery tool. This study explored the impact of three distinct video styles: a whiteboard animation, a recorded discovery lecture by one of the discoverers, and a documentary short film featuring both discoverers in conversation on student outcomes in a large-enrollment undergraduate biology class. Students were randomized to watch one of these three formats, all covering the same scientific content (i.e., the Meselson and Stahl experiment), followed by a post-video survey. The documentary film, “The Most Beautiful Experiment,” which integrated interpersonal storytelling and informal dialog, had the most significant impact on outcomes related to affective learning, including science identity, attitudes about biology, speaker relatability, and emotional engagement. No significant differences in knowledge gains were observed across video styles. This study highlights the potential of personalized and embodied video formats to enrich STEM education and warrants further research into their broader applications. 

Research-intensive universities aim to conduct cutting-edge research while providing the knowledge and skills necessary to prepare students to excel in their respective fields. As student enrollments surge, many institutions have turned to hiring teaching-focused faculty. In the University of California (UC) system, there exists a unique position known as the Professor of Teaching (PoT). This position is tenure-eligible, and members are required to engage in classroom teaching, scholarly activities, and service responsibilities. To shed light on the background characteristics, roles and perceptions of the impact of teaching-focused faculty in research-intensive institutions, we collected survey data from STEM PoT faculty across the UC system. We employed a mixed methods approach, using descriptive and inferential statistics to analyze quantitative responses and thematic analysis to examine open-ended qualitative data. Our analysis shows that pre-tenure PoTs place greater emphasis on scholarly activities relative to their peers who have been in the role for longer. However, their training and the institutional resources provided may not align with expectations for scholarly activities. Additionally, we find that PoTs who engage in research perceive that they have a more significant impact on their colleagues’ teaching. This finding underscores the value of research, even for teaching-focused faculty. This study informs the evolving landscape of teaching-focused faculty within research-intensive universities and provides recommendations for administrators considering how to ensure that their institutions are fulfilling their educational mission.
