This research design involves testing the same group of participants in different conditions, in this case, with and without the teacher smiling. The first and third weeks serve as the baseline measure while the second week is the experimental measure. By comparing the number of questions asked in the different conditions, the teacher can determine if her smiling behavior has an effect on the students' behavior.
