The present study was conducted to compare the effectiveness of two educational methods of learning by summarizing, and learning through teaching on the comprehension of sixth grade elementary male students. This was an applied study and the research design was experimental with a pre-test and post-test approach and the control group. The study population included all sixth grade male students at Allameh Tabataba'i School, who were studying in the academic year of 2018-2019. The random available sampling method was used in this study. The total number of students were 59, all of which were participated in the study and divided into three different groups by random convenience sampling method. Then, the first experiment group members (15 subjects) were trained in 8 learning sessions through teaching method. The subjects in the second experimental group (15 subjects) were trained in 8 learning sessions by summarizing method. The control group (n = 29) received no training. Two researcher-made questionnaires were designed to assess the comprehension level of the students. The data were analyzed using analysis of covariance in the SPSS software. Emphasizing the findings of the research, it can be argued that both learning methods had a favorable effect on the students' comprehension, and increased the students' comprehension level. Based on these findings, one can conclude that these two educational methods have a great impact on increasing the comprehension of sixth grade elementary students.

Executive functions and visual perception are variables that play important roles in learning and educational improvement. Therefore, the aim of this study was to investigate the effectiveness of attention rehabilitation on executive functions and visual perception of students with learning disorder and the study was of quasi - experimental type with pre-test, post-test and control group. The statistical population included all elementary school students in Rafsanjan in the second semester of 2018. The sampling method was multi-stage cluster method and the statistical sample of research involved 20 students with specific learning disorders, selected and replaced by a simple random method in two groups of experiment and control groups (2 groups of ten). The research tools were the visual perception test of Frostig and the Wisconsin cards. After performing pre-test on both control and experimental groups, the experimental group was trained using Captain Log software for 12 session, and at the end, the post-test was performed on both groups. The data were analyzed using SPSS v.24 software and statistical analysis of covariance (MANCOVA). The results of statistical analysis showed that attention facilitator rehabilitation is effective in improving students' ability in visual perception test. Also, the results revealed that rehabilitation of attention can significantly improve the performance of children with learning disorder in the executive functions.

Today, education experts mostly aim to detect significant causal variables leading to students’ achievements in educational settings. The present study aimed to investigate the relationship between executive functions and self-regulated academic learning regarding the mediating role of metacognition and working memory among university students. This research was a correlational study using structural equation modeling. The statistical population included of all students of Shahid Chamran University of Ahvaz in the academic year 2018-2019. A total of 351 students were selected by multi-stage cluster random sampling. The research instrument included the Metacognitions Questionnaire (MCQ-30), Cognitive Abilities Questionnaire, the Self-Regulation Questionnaire (SRQ), and the Test of Information Processing Skills (TIPS). The collected data were analyzed using structural equation modeling. The findings revealed no significant and direct relationship between executive functions and self-regulated academic learning (P>0.05). However, there was a significant and direct relationship between executive functions with metacognition and working memory (p <0.01). Moreover, a significant relationship was observed between metacognition and working memory with academic self-regulated academic learning (p <0.01). In this regard, metacognition and working memory fully mediated the relationship between executive functions and self-regulated academic learning. The study findings provide university students and experts with an appropriate model since, as the theoretical foundations of the proposed model documented, academic achievement and well-being are mainly dependent on executive functions. Accordingly, metacognitive skills, including self-regulated academic learning, can be improved by promoting the executive functions among university students.

The present paper sought to investigate gender differences in the speech pauses made by Iranian bilingual (L1: Turkish and L2: Persian) learners of English as a foreign language (EFL). To this end, the pauses made by males and females were compared. Via an Oxford Placement test, a convenient sample of 40 bilingual advanced EFL male and female learners were selected from several English language institutes in Tehran, Iran. Three reading passages (English, Persian, and Turkish) were used to measure students’ fluency in terms of their speech pauses in the texts they read. As learners started to read the passages, their speeches were recorded. The collected data were analyzed by means of Praat Software. The data were analyzed in terms of the frequency and duration of the recorded pauses. The results indicated that that there were not any statistically significant differences between males and females regarding their pause frequency and duration across languages. Accordingly, the results represented more similarity than difference across the groups. The implications of the study results are discussed.
