Comparing of The effectiveness of the four components and Gagne instructional design models in student learning

The purpose of this paper was to comparing the effectiveness of four component and Gagne instructional design models with each other and conventional method in science learning. To achieve this purpose, the experimental method with pre-test and post-test and control groups was used. The entire male students of Karaj city were the population of this research. Sample was selected through cluster sampling that include 60 mentioned population that divided in three groups (experimental1, exprimental2 and control group). Intended subject matter presented for Experimental 1 through four component instructional design model, experimental 2 through Gagne instructional design model and for control group through conventional method. For all three groups, pretest, posttest test was executed. For descriptive data analysis, mean and standard deviation scores, has been used and for inferential statistic, covariance analysis was used to examine the hypothesis. The results showed that there is significant difference between conventional training and four component a Gagne instructional design models and between four component and Gagne instructional design models was significant difference. Four component (IDM) is better than Gagne (IDM) four learning complex learning.
