Purpose : The present research was conducted with the aim of comparison of psychomotor skills and social adjustment in elementary students with and without preschool history. Methodology : This research in terms of time was cross-sectional, in terms of purpose was applied and in terms of implementation method was causal-comparative. The study population was the first to third grade students of Shiraz Kodak Afarin Educational Complex in the academic years of 2019-2020, which according to the Krejcie and Morgan table number of 144 people (90 people with preschool history and 54 people without preschool history) were selected as a sample by simple random sampling method. Data were collected by psychomotor skills test (Lincoln Oseretsky, 1950) and adaptive behaviors inventory (Lambert et al, 1974) and analyzed by independent t-test in the SPSS software. Finding : The results showed that elementary students with preschool history in compared to elementary students without preschool history significantly had a more favorable situation in terms of psychomotor skills (and all its components including touching, bending on the toe, harmonious tapping of the foots, standing on one foot, walk backwards and finger skills) and social adjustment (and all its components including violent behavior, antisocial behavior, rebellious behavior, unreliable behavior, avoidance, stereotyped behavior, inappropriate social behaviors, bad voice habits, bad or strange habits, hyperactivity tendency and psychological distress) (P<0.01). Conclusion : The results indicated the effect of preschool on psychomotor skills and social adjustment in elementary students. Therefore, to improve the characteristics of students is necessary to use a preschool education course.

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.
