The Lab worked closely with Professor Kathleen Hess to create an online exercise to develop students' understanding of the processes occuring at the molecular level during a laboratory procedure. The exercise focused on the procedure for recrystallization, a technique commonly used to purify a contaminated compound. In the exercise, the procedure was interspersed with questions asking students to provide conceptual explanations for certain steps and possible outcomes. Students received feedback on their exercise responses and Professor Hess used these responses to identify concepts to review during her lecture.
Brief narrated animations created by Professor Hess and the Lab during the summer of 2015 provided a visual explanation of key concepts in the context of the laboratory procedure. These animations appeared as part of the feedback that students received on their exercise responses.
