• Resumen

  • Online prelaboratory videos and quizzes were prepared for all experiments in CHEM 231, Organic Chemistry I Laboratory. It was anticipated that watching the videos would help students be better prepared for the laboratory, decrease their anxiety surrounding the laboratory, and increase their understanding of the theories and concepts presented. Moreover, the videos were implemented to increase consistency across the different laboratory sections of the course. The videos consisted of voice-over Powerpoints with photographs of laboratory glassware set up, explanation/description of laboratory procedures, and important safety considerations and waste disposal instructions. Students watched the videos at home before they came to the lab to conduct their experiment. Following their implementation, students completed a postlab survey to evaluate the effectiveness of the videos on their preparation for lab and on their understanding of the concepts and theories of the experiments. Students reported that the videos helped them to feel better prepared to conduct their laboratory experiment and helped them to better learn and understand the concepts presented in the experiment. Watching the videos also assisted the students in recognizing how the laboratory themes and reactions were related to the Organic Chemistry I lecture topics. Finally, the implementation of the videos increased the consistency of content delivery across all sections of the course.
