The Science (Students) of Course Change #3 – Two-Stage Exams in Organic Chemistry
Published: 23 February 2023
Two-stage exams are a form of assessment that bring student collaborative learning into the testing process. While a typical two-stage exam gathers students to re-do the exam as a group after completing it individually, this project investigates the use of “group first” two-stage exams. In this format, piloted in Organic Chemistry I midterm exams, students complete the group component before the individual component, and each part has related, but discrete questions. After each midterm, students completed a detailed survey containing both opinion-ranking and open-response questions regarding their perceptions of the midterm exam format. Analysis of the data revealed that most students enjoyed the “group first” two-stage exam, reporting reduced exam anxiety, increased content comprehension and improved performance depending on the difficulty and the content of the exam. Overall, although it sometimes caused confusion, the advantages of “group first” two-stage exams outweighed the disadvantages.
