Abstract TIMSS is one of the most important comparative studies that assess the status of mathematics and science education. In the past few decades, Iranian students have performed poorly. Therefore, the purpose of this study is to differentiate successful students from unsuccessful based on individual factors to investigate what individual factors can be the basis for the success of individuals in this evaluation. The method of this research is correlational in the form of differential equation. The statistical population is all schools participating in the TIMSS 2019 exam. The sampling method is regular two- stage cluster sampling method that was performed in the TIMSS 2019 exam. The data collection tool in this study is the questions of the 2019 TIMSS Questionnaire for family, student, principal and teacher, which was published by the International Association for the Evaluation of Academic Achievement in 2019. Differential analysis method was used to analyze the data. The findings of this study showed that the number of books with a resolution of 0.630, science in school with a resolution of 0.462, assets with a resolution of 0.261, gender with a resolution of 0.231 and mathematics in school with a resolution of 0.210 have the greatest impact on the separation of successful students from unsuccessful students based on individual components. Therefore Having effective textbooks, presenting materials in a practical way and students' practical learning, and economic and financial status are among the individual factors influencing the success of the TIMSS and PIRLS test.

Abstract The aim of present meta-analysis was to examine the effects of personal, family and schooling factors on academic performance and droppout among Iranian secondary students. The published and archived researches in journals, databases, and printed ones relating to academic achievement and dropout have collected. According to the inclusion criteria, 65 articles included in the analysis. After coding the articles, using Orwin’s method, 98% inter-rater agreement among raters have been gained. The random-effect model of DerSimonien and Laird was used with software. It was revealed that in predicting academic achievement, the average effect sizes for all factors and combination of factors 0.270(95CI%:0.218-0.321, Z=9.801, P<0.001) and for dropout 0.521(95CI%:0.404-0.621, Z=7.580, P<0.001). According to the findings, it was revealed that in academic achievement, personal factors and in dropout, schooling factors play main roles, so it is recommended to pay attention to the personal characteristic of students and constructive interactions among parents with youth and school staff.

Abstract The purpose of this study was to determine the causal relationship between achievement goals and academic performance through mediating of academic buoyancy in secondary high school girl students in Ramhormoz. The research method was descriptive correlational. The study population consisted of all secondary high school girl students during the academic year of 2018. From this population, 302 students were selected by multistage cluster sampling. The instruments used included the achievement goals scale of Middleton & Midgley (1997), academic buoyancy scale of Hossein Chari and Dehghanizadeh (2012) and the students' average as an academic performance index. The data were analyzed using correlation matrix and path analysis statistical methods using Spss18 and Amos 23 software. The results showed that both variables of achievement goals (goals of master, performance and avoidance) and academic buoyancy had a direct effect (p

Abstract The general aim of the present research was to develop a model for predicting academic performance based on emotional intelligence, problem-solving skills and achievement motivation with the Mediation of Learning Strategies (Cognitive and Metacognitive) in students of smart and ordinary schools. The research method was correlational with a prediction type. The population in the current research included all the secondary school students of Tehran, among which 583 students were selected for the study sample through multi-stage cluster sampling method. For gathering the data, Hermans achievement motivation questionnaire (1970), Social Problem Solving Inventory-Revised Short Form (SPS-R: SF), Learning Strategies Questionnaire (Karami et al, 2002), Bar-On Emotional Quotient Inventory (2000) and Academic Performance Questionnaire of Dortaj (2004) were used. Findings suggested that the direct and indirect effect of emotional intelligence and achievement motivation on academic performance of students of smart schools is significantly higher than its effect on the academic performance of students of ordinary schools. No significant difference was observed between the direct and indirect effect of problem solving skills on academic performance of students of smart and ordinary schools. Findings of the present research had useful implications for policy makers in the education area.

Abstract

Abstract The purpose of the present research is to compare the effect of university image (brand) on academic self-concept of university students. The general outline of this research is a bit of survey and correlation. The statistical population of this study was all students (boys and girls) of the faculties of psychology and education of Allameh Tabatabai University and Lorestan University with 1200 students who were studying in the academic year of 1994-94, of which 400 were randomly assigned with appropriate allocation were chosen. The research tools were two researcher-made questionnaires of the mental image of the university and the academic self-concept. To determine the reliability of the test, Cronbach's alpha method was used and the Cronbach's alpha coefficient of the mental image questionnaire (brand) from the university was 0.79 and Cronbach's alpha coefficient was self- 0 is. In order to analyze the data, Spearman correlation test, t independent groups, Kolmogorov, Smirnov and Friedman have been used. The findings show that the type of look at the mental image (brand) of the university and the academic self-concept is not the same among the students of Allameh Tabatabai University and Lorestan. Also, there is a positive and significant relationship between the scores of the mental image of the university with the scores of the general environment, academic environment and non-university environment with academic self-concept.
