The present study was conducted to investigate the mediating role of achievement anxiety in the relationship between perfectionism and cognitive flexibility in math learning in students. The study was correlational using structural equation modeling. The statistical population included senior high school female students in the academic year of 2022-2023. According to the obvious variables, allocation of 25 coefficients, and taking into account the incomplete questionnaires, 231 students were selected by convenience sampling. The instruments included Hewitt and Flett’s perfectionism (1991) questionnaire, Dennis and Vander Wal's cognitive flexibility (2010) questionnaire, and Alpert and Haber's achievement anxiety (1960) questionnaire. Also, the students’ math scores at the end of the semester were used to measure their math learning. The data were analyzed by Pearson's correlation coefficient test and structural equation modeling using SPSS18 and AMOS24 software. The results showed that perfectionism and achievement anxiety have a negative direct effect, and cognitive flexibility has a positive direct effect on math learning. Also, perfectionism and cognitive flexibility have an indirect effect on math learning through achievement anxiety. The research model was also confirmed and the result showed that the variable measurement models have a good fit and 41% of the math learning variance is explained by the research variables. The findings of this research can be beneficial for teaching and learning of students. With educational planning and helping students, their cognitive capacities and competencies can be increased and their mathematical learning can be effectively improved.

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.

Emotions are the primary source of motivation and movement in humanbeings. Positive emotions help maintain and guide responses and behaviors. These emotional experiences, in academic situations, play an important role in shaping students' judgments, decisions, priorities, and behaviors by providing basic information. The aim of this study was to investigate the causal relationship between Hexaco personality traits and English language anxiety with the mediating role of positive academic emotions in students. This study was applied in terms of purpose, and considering how information and data were collected, it was descriptive-correlational.The statistical population included all 525 ninth grade female students of 10 public girl’s junior high schools in Babol, in the academic year 2020-2021. Using Krejcie and Morgan (1970) Table, 225 students were selected as the research sample through simple random sampling method. The instruments of the study included the HEXACO Personality Traits Questionnaire (De Vries & Van Gelder, 2013), Positive Academic Emotions Questionnaire (Pekrun et al., 2005), and English Language Anxiety Inventory (ALI, 2017).To analyze the data, Kaiser-Meyer-Olkin test, Bartlett’s test, correlation coefficient, regression, path analysis and structural equation modeling were used. The research model showed a very good fit.The findings showed that there is a significant relationship between the students’ personality traits, positive academic emotions and English language anxiety. In addition, personality traits and positive academic emotions have a direct effect on students' English language anxiety. Also, personality traits have a significant effect on students' English language anxiety through the mediating role of positive academic emotions.

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.

Purpose: based on the role of consistency and academic engagement in academic performance, this research aims to determine the effectiveness of flourishing education on the consistency and academic engagement of students. Methodology: This research was semi-experimental with a pre-test, post-test design, and a control group. The statistical population of this research was the second-grade high school students of Chalus city in the academic year of 2019-2020. The sample size was 30 people who were selected by convenience sampling method and replaced by the simple random method in two equal groups including experimental and control groups. The experimental group had flourishing education for two months at 8 sessions (one session a week), and the control group did not receive any education. The research tools were Duckworth, Peterson, Matthews & Kelly's (2007) consistency questionnaire and Reeve & Tseng's (2011) academic engagement questionnaire. The data were analyzed by multivariate covariance analysis methods in SPSS software at a sig. level of 0.05. Findings: the results showed that flourishing education increased students' consistency (and both of its dimensions include stability in interest and persistence in effort) and academic engagement (and all four of its dimensions include cognitive, emotional, behavioral, and agency) (P<0.05) after controlling for the effect of the pre-test. Conclusion: it is essential to use the mentioned method to improve academic characteristics by considering the effectiveness of flourishing education in increasing consistency and academic engagement in students.
