2020 
BACKGROUND The present study was conducted to design and evaluate the software and web-based curriculum based on Pender Model in order to promote students' physical activity. METHODS This is a quasi-experimental study conducted on 225 eligible students who were randomly divided into two groups of web and software-based intervention and control. The sample size of the study was selected using stratified sampling method. The evaluation was done with pre-test and post-test and follow-up, which were performed immediately two and six months following the intervention. The data were analyzed employing statistical software SPSS using descriptive statistics, chi-square, one way ANOVA, and repeated measures ANOVA. RESULTS The obtained results revealed that the level of physical activity after the intervention in the web and software groups significantly increased compared to the control group (p < 0.001). Moreover, the mean score of Pender model constructs, immediately two and six months after the intervention, was significantly different in the web and software groups (p < 0.001). CONCLUSION Our results indicated that, providing tailored message based on health promotion model's constructs has a positive effect on promoting physical activity of students.
