This study aimed at comparing the effectiveness of computer-based and computer-assisted instruction on the interaction of the elements of Teaching-Learning process in the second grade of the first secondary school science class in Asadabad. The study is part of the quasi-experimental projects that uses pre-test and post-test experimental groups 1 and 2. The statistical population of the study included all the male students in second grade of high school in the school year 2013-14 in Asadabad- Hamedan, with the volume of 852 students. Multi-stage cluster sampling was used to select the sample. The sample size was 100 students that were placed in pre-test and post- test groups 1 and 2. The first group studied the instructional CD with teacher guidance and the second group studied the instructional CD without teacher guidance. Both groups received their instruction in the network environment with the NSS software support. The research instrument included students’ interaction levels based on six interaction elements with 60 questions in Likert scale (very high, high, medium, low, very low). The multivariate analysis of covariance was used to test the hypotheses. The results suggest that in Teaching-Learning elements’ interaction that include six dimensions, there is no significant difference between computer-based and computer-assisted instruction in five dimensions except in content-content dimension in significance level %5. The findings show that computer-assisted instruction, the training and simulation activities with the guidance provided by the network and teacher is more effective compared to computer-based instruction.
