Present research studies performed thesis about academic failure between academic years 1990-2012 in Tehran Universities. Within related projects, 55 projects which had information necessary for analysis were selected as final sample. CMA-2 software was used for calculating Coefficients. Results of Q test showed that primary studies are not homogenous and studying Nfs showed that there isn’t protection of distribution within studies. Dual and Toidi correction test was performed for both constant and random models. Measure of total effect for all studies under both constant and random models, was gained statistically meaningful. Also, measures of effect in separation of distribution year, sampling method, sex of sample, education program, research method and factors affected on educational slump were gained statistically meaningful. Average of effect measures was 0.312 and educational factor, with effect measure higher than average, showed the most effect on educational slump. The results showed that variables of education, socioeconomic, individual factor, family factor and sex factor had the most effect on educational slump respectively. Also, studying hypotheses showed that there is meaningful difference between effect measures of educational slump according to year of research, sampling method, sex, education program, meaningful level, factors being effective on educational slump and research method.

Background: attention deficit hyperactivity disorder is the most common developmental neurological disorder in children the problems of which remain after puberty. Early diagnosis and intervention of this disorder in the home and school environment is essential to decrease the problems caused by it. Early diagnosis and intervention requires epidemiologic studies. The studies on the prevalence of ASHD have had different results due to applying different criteria definitions evaluators and instruments. Objective: the present paper aims to conduct a meta analysis on the epidemiologic studies of ADHD among Iranian elementary school students. Conclusion: the results of present meta analytical research is consistent with those of many related studies in terms of the prevalence rate of ADHD the proportion of disorder between girls and boys and also the prevalence rate of subtypes among Iranian elementary school students.

Background: test anxiety is frequently viewed as a major factor that can impair test performance and lead to underachievement. Objective: the current study was a meta analysis of the performed studies in the area of therapeutically methods applied to reduce test anxiety. Method: to do so the meta analysis was used as a statistical technique to collect to combine and to summarize the performed studies in the regarded area which finally led to the collection of 45 convenient studies. Conclusions: the study results show that from among the applied therapeutically methods in reducing the test anxiety there has been greater success for behavioral method followed by cognitive method and the therapist should pay more attention to these methods.

Background: health one of the most important resources of humankind life is so effective on the quality of human life and advancing the society goals. Bjectives: this study was carried out to compare the total index of mental health in males and females using the meta analysis method. Method: 26 studies were gathered through through net surfing in internal databases as well as manual searching in various Tehran universities and their data were encoded. Results: cohens index of effect size in the fixed and random models was respectively .286 and .301 which was indicative of a better status for men in the total index of mental health than women.
