The design used by Mr.Gomez is One-group time series. This is because he is only recording the turn-in rate for the same group of students for two different time periods (before and after the reward). It is not a counterbalanced design as there is no alternate assignment or order of conditions for different groups, nor is it a factorial or single-subject design as there are no multiple independent variables or individual cases being studied.
