Effectiveness of Advanced Organizer Model on general Chemistry Learning learning at Hasheminejad Educational Center

Teaching methods are important issue in higher education. This research aimed to study the effect of the advance Organizer Model as appropriate method on theoretical courses. Research design was quasi- expermimental with pretest posttest and control group. Participants were a sample of (n=36) male student in Hasheminejad Center for Higher Education (N=111) who took General Chemistry course. They were randomly assigned to control and experimental groups. the experimental group received training under AOM. Findings indicated that the experimental group scored significantly higher on their final chemistry exam than the control group.
