Group A received the module on March 12th, 1973 and was instructed to try to complete it in three weeks. This time schedule was unrealistic so the time allotment was changed to four weeks. The observation instrument was administered as a posttest to this group on April 9th. During that week it was also administered as a pretest for Group Bl. Group B1 served as a control for Group A since Group A had completed use of the module and Group B1 had not begun. Group B2 received the module on the week of April 9th but did not receive a pretest since this was part of the design.
Groups B1 and B2 received a posttest observation on the week of May 10th. Group C was pretested also to serve as a control for Group B2.
All of the teachers using the module administered the
Pupil Questionnaire as the preassessment of the module. They then used this instrument to determine whether they had already mastered the objectives, had mastered some of the objectives or would benefit from using the entire module. After completing the module the teachers again administered the Pupil Questionnaire to determine whether the objectives of the module had been mastered.
