This research has studied the effectiveness of different instructional media in concept formation of the physics concepts, the subject of Force in the first grade of junior high school.The goal was the comparison of three kinds of media with one another:1- The Integrative instructional medium (a combination of Skinner’s programmed instruction, Gagne’s phases of learning, and a daily lesson plan), 2- The Danesh yar instructional medium (available on the market), and the human instructional medium(teacher). The research design was multiple-group pretest-posttest and the population was all boy and girl learners of the junior high schools of Kerman city in the year of 1386-87. The cluster sampling was six classes in six junior high schools at random and the gathering instrument was a physics achievement test which was prepared by the researcher. The test was conducted as a pretest and a posttest with the experimental groups (Danesh yar and Integrative) and the control groups (human). To determine the effectiveness of each medium in concept formation, these steps were taken: giving the pretest, implementing the independent variable (conducting the instruction), and giving the posttest. To analyze the given data, the descriptive and inferential statistics were used. The results of the descriptive data showed that all the boy and the girl learners are weak in physics and the Integrative medium was effective in physics concept formation. The overall of the inferential data results showed that all groups that were instructed by the Integrative medium were have achieved the “concept formation” better than the groups who were instructed by the human and Danesh yar media. And the groups that were instructed by human medium were the better achieved group than the groups who were instructed by Danesh yar medium.
