Warm Up Gallery Walking

Students consistently work in homework groups in my class. Each group consists of 3 or 4 students.

At the start of class, a group representative picks a problem out of a bowl. The problems are of similar complexity and reflect topics covered in the previous class. The group works together to solve the problem on the board. Each group solves a different problem.

After 5 minutes, student groups rotate throughout the room reading, correcting, and commenting (using different colored chalk) on solutions written by other groups. Anywhere from 5 to 7 different examples are considered using this approach. I then ask if there are lingering questions or problems they’d like to talk through as a collective.

A student volunteers to take pictures of the solutions and commentary and sends them to the rest of the class.

On November 12, 2019, Muhlenberg colleagues gathered to share their teaching hacks. Teaching hacks are relatively simple strategies that we might use to improve student learning or reduce our workload. These strategies might free up additional class time, increase the efficiency of our practices, or better support our ability to work on scholarship or service.
