The Effectiveness of Complementary and Extra Curriculum Activities on Students’ Self-Belief

The main purpose of this research is to study the effect of complementary and extracurricular activities on students' self-belief. It is a pre-test and posttest quasi-experimental design with a control and an experimental group. The population consisted of 223 sixth grade female students in BardSir. The sample consisted of 40 people who were selected by convenience sampling into experimental and control group. Data analysis was performed using multivariate analysis of covariance (MANCOVA) using SPSS-20 and variance analysis and t-test were used to evaluate the hypotheses. The results of the study showed that training in complementary and extracurricular activities, including participation in artistic activities, membership in student organizations, participation in scientific activities and participation in religious activities, affects the self-belief of sixth grade female students in Bardsir. Comparison of the above variables showed that complementary and extracurricular activities have a positive effect on students' overall social and academic self-belief. However, it did not have a significant effect on individual and family self-belief. According to the role of education in creating a developed, complete and transcendent personality, the research results indicate the importance of considering designing and compiling complementary programs and various extracurricular programs along with formal curricula, tailored to the needs, interests and conditions of students.
