The purpose of this study was to determine the effectiveness of web-based distance learning model in the context of a constructivist learning approach on learning performance, satisfaction and attitude of Payame Noor Sardasht students. The research method was quasi-experimental with pretest-posttest design. The statistical population of the study included all students of Payame Noor University of Sardasht who selected 45 people as the research sample, using Morgan table and cluster sampling method. Of these,15 students were assigned to conventional distance education group, 15 to the distance education group based on reproductive learning, and 15 to the project-based group. Data collection tools included a teacher-made test to measure learning performance as well as a researcher-made satisfaction and attitude questionnaire that the content validity of the teacher-made test was reviewed and approved by professors. And its reliability through splitting method was 82% in pre-test and 85% in post-test using Spearman-Brown formula. The content validity of the satisfaction questionnaire and the attitude questionnaire were reviewed and approved by experts and the reliability of the satisfaction questionnaire was 84% and the attitude questionnaire was 80% using Cronbach’s alpha. Data analysis was performed using inferential statistics and one-way analysis of variance. Emphasizing the research findings, it can be claimed that both web-based distance learning models have a positive effect on students learning, satisfaction and attitude. Based on these findings, it can be concluded that these two educational models (project-based learning and reproductive learning) have a great impact on increasing students’ learning performance, satisfaction and attitude.
