Activities

This page includes links to a complete set of in-class Activities (with answers) from Bethe Scalettar’s Spring 2026 Biomedical Imaging course. Activities are used to reinforce key course concepts, break up the pace of lectures, and encourage class attendance. Students are given class time to complete each Activity, alone or in consultation with classmates. The instructor then goes over the Activities and answers. Activities are collected at the end of the class period and used, without being graded, to assess and reward student attendance. Activities and Answer Keys are posted online before examinations. Many variations on the content and frequency of Activities are possible.
