The Effect of Training Based on Pebble in the Pond Instructional Design Model on Learning and Retention of Students

The aim of this study was to investigate the effect of education based on Pebble in the Pond instructional design model on learning and retention of the students. The research population in this study included 170 students of Educational Sciences oriented in Educational Technology at Arak university, and the study samples were students who have chosen the system- based instruction course. Purposive sampling was used for selecting the samples.Total sample size was 30 subjects randomly divided into two 15-person classes. The researcher-made instrument used in this study was learning and retention test. The validity of test consist of formal, content validity was confirmed by professors of the education sciences and its reliability with Kuder-Richardson 20 Formula was measured as 54%. This test used pretest and posttest and it was conducted for both experimental and control groups in the same condition. For data analysis, repeated measure ANOVA was used. The results showed that the method of teaching based on Pebble in the Pond instructional design model had significant effect (p <0/05) on learning and retention of the students.
