The purpose of this study was to compare the teaching process interaction behavior of teachers who planned for classes with those who did not plan. Senior physical education majors served as the teaching subjects for this study—six in the planning (experimental) group and six in the no-plan (control) group. Each teacher taught the same lesson content for a 15-minute episode. The planning group spent 1 hour before the lesson writing explicit plans, while the control group was given 2 minutes just before the lesson to gather their thoughts and be informed of the content to be covered. The behaviors of all teachers were observed by the Cheffers Adaptation of the Flanders’ Interaction Analysis System (CAFIAS). The results indicated significant differences in only two interaction categories: amount of directions given and the amount of silence. Both variables were better for the planning group.
