Action:

• Explain to students that you want them to interact with all of the students in the class. Ask them to try to sit in a different seat in each class. Remind students to do this in the first few classes, but you need not check whether or not students are always sitting in a new seat.
• Remind students to introduce themselves to their new neighbor.

Reason:

• Students are likely willing and interested in meeting people in their class, but it can be awkward for students to approach other students in the class that they don’t know. Without encouragement students might only sit with students that they know or perceive themselves to be similar to.
