Numerous online resources provide a variety of content for a wide range of STEM topics; however, they tend to function as isolated tidbits that provide content-specific knowledge. Application-based science education videosaddress the overlooked issue of concept to application by implementing experimental components in their videos and fostering connections with everyday applications. We utilized the Journal of Visualized Experiments (JoVE) peer-reviewed science education videos as homework assignments to supplement lectures on the topics of enthalpy, entropy, rate laws, and Le Châtelier’s principle in a second-term general chemistry course. Student learning was assessed through the analysis of pre- and post-video conceptual quizzes, and value surveys were also conducted to gather student feedback about the videos. Our investigation shows that using these videos in the course significantly improved student learning and reinforced conceptual understanding for important foundational concepts, and these results hold even for students who did not feel positively toward the videos.
