Educational self-efficacy and its relationship with learners' different psychological traits can have a tremendous effect on the success or failure of the students. Thus, the present research sought to investigate whether academic self-efficacy has an effect on the students' stress derived from the education expectations based on such mediating factor as the difficulty of emotion regulation. The research method was descriptive-correlational based on structural equations. The statistical population consisted of all 800 junior female high-school students, 9th grade, from 16 State schools in the third district of Tehran. To decide on the sample size according to the number of observed variables, assigning a coefficient of 25 for each (7 variables in the model), and taking the possibility of incomplete questionnaires into account, 200 people were chosen by cluster sampling method. The data were gathered using three questionnaires: self-efficacy (Jinks & Morgan, 1999), difficulty in emotion regulation (Gross & John, 2003), and educational expectation (Ang & Huan, 2006). Using the structural equation modelling, the data analysis revealed that educational self-efficacy and difficulty in emotion regulation had a direct and significant effect on the stress caused by educational expectations. Also, an indirect effect of educational self-efficacy with the mediation of difficulty in emotion regulation was captured and the research model was revealed to predict 63% of the stress variable due to educational expectations. The study revealed the importance of cognitive factors in explaining the stress caused by academic expectations.

This study aimed to investigate the intermediating role of self-regulation in the relationship between mathematical educational beliefs and students' math anxiety. The descriptive method was correlation sort which is based on structural equations. The statistical subjects of this study were selected from 2710 male students in the ninth grade of secondary school in public schools in the 4th district of Tehran in the educational years 2020-2021. In this study, 300 students were chosen by a two-step cluster method as the sample size, to collect data, Plake and Parker’s Math Anxiety Questionnaire (1982), Ledder & Forgasz’s Math Educational Beliefs Questionnaire (2002), and Sawari & Arabzadeh’s Self-Regulation Questionnaire (2013) were applied. Structural equation modeling(SEM) with SPSS 18 and AMOS23 were used to analyze the data. The findings showed that math educational beliefs and self-regulation have a direct effect on students' math anxiety (p<0.01)., and mathematical educational beliefs have an indirect effect on math anxiety with mediating of self-regulation (p<0.01), and the research model was approved. This study shows the importance of educational cognitive elements in math anxiety and it is suggested that the educational systems set plans to improve students' positive educational and cognitive beliefs and as a results decrease anxiety in educational settings especially math anxiety.

Emotional self-regulation plays a very critical role in promoting intelligence beliefs and improving students' academic performance. Through emotional self-regulation, students can believe in the effectiveness of their intelligence and achieve higher performance in their educational and learning processes. The aim of the present study was to investigate the relationship between IQ beliefs and chemistry performance with emotional self-regulation mediation in students. This study was applied in terms of purpose, and considering data collection procedure, it was descriptive-correlational. The statistical population included all 275 female students of 11 public senior high schools in Mahmudabad, the 11th grade, in the academic year 2020-2021. Based on the census method, the whole population of the research community was used as a sample. The instruments used for data collection included the Intelligence Beliefs Questionnaire (Babaei, 1998) and the Emotion Self-Regulatory Questionnaire (Gross & John, 2003).  Also, the final score of the chemistry course was used as the chemistry performance of the participants. To analyze the data, Kaiser-Meyer-Olkin test, Bartlett’s test, correlation coefficient, regression, path analysis and structural equation modeling were used. The findings showed that there was a statistical significant relationship between intelligence beliefs, emotion self-regulation and students' chemistry performance. In addition, intelligence beliefs and emotion self-regulation have a direct effect on students' performance in chemistry. Also, intelligence beliefs have a significant effect on the performance of students' chemistry lessons through the mediation of emotion self-regulation. It should be mentioned that the research model had a very good fit. Given that intelligence beliefs and emotion self-regulation can predict the performance of students in the chemistry course, it is recommended to modify cognitive beliefs and teach emotion self-regulation techniques in order to improve students' academic performance.
