Abstract
The present research aims to examine the effect of teaching studying methods of reading and comprehension, note-taking and writing, and exam techniques and stress management with emphasis on cognitive and meta-cognitive strategies on academic achievement and motivation achievement among Iranian students with residency in Tajikistan. For this purpose, using empirical method and multi-group pre-test and post-test design, 80 students were considered in four groups(3 experimental groups and 1 control group). Response was given to Hermans achievement motivation questionnaire by the students at four groups and their Grade Point Average for previous year was registered, and the individuals in the experimental groups were trained during 10 sessions. After intervention, Hermans achievement motivation questionnaire was refilled by the students and their new Grade Point Average was registered. Ultimately, the research data were analyzed via Multivariate analysis of covariance (MANCOVA). Results of statistical analyses indicated that training studying techniques of reading and comprehension, note-taking and writing, and exam techniques and stress management affect achievement motivation and academic achievement.

Abstract
Mathematical reasoning is the ability of inductive and inferential reasoning with mathematical concepts that underlying cognitive variables play an important role in explaining it. The purpose of this study is to model the role of divided attention and working memory in mathematical reasoning with the mediation of mathematical knowledge and fluid intelligence in fourth grade elementary students. This study is non-experimental (descriptive) and a type of correlational study in which data were analyzed by Path Analysis. The statistical population of the research included all male fourth-graders of the primary schools in District 4 of Qom from which 213 students were randomly selected by two-stage cluster sampling. The study used different measures and instruments including the Integrated Visual and Auditory Continuous Performance Test-Second Edition (IVA-2 CPT) for measuring different types of attention, the Working Memory Index of the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV), the Culture Fair Intelligence Test (CFIT), the knowing questions test and the mathematical reasoning questions test of TIMSS 2015. The findings of the study showed that all path coefficients are significant and appropriate model fit indices were obtained. The results indicate that working memory influenced by divided attention predicts mathematical reasoning with the mediation of mathematical knowledge and fluid intelligence. The research helps to develop in mathematics learning and cognitive rehabilitation of mathematical disorders by identifying the role of important cognitive variables in mathematical reasoning.

Abstract
The aim of this research was to predict students' academic procrastination based on metacognitive beliefs about procrastination with the mediating role of test anxiety The research method was descriptive-correlational. The statistical population included all undergraduate students of Shahid Beheshti University of Tehran in the academic year of 2019-20, from which 320 (206 females and 114 males) were selected by multi-stage cluster sampling. The Procrastination Assessment Scale for Students, Spielberger test anxiety questionnaire and Metacognitive Beliefs about Procrastination Scale were used to collect data. Data were analyzed by structural equation modeling. Findings showed that the suggested conceptual model has a good fit with the data. The variables of test anxiety and metacognitive beliefs about procrastination accounted for most of the variance in academic procrastination, respectively, and explained a total of 28% of its variance. Negative metacognitive beliefs about procrastination only indirectly affected academic procrastination through test anxiety, and full mediation was endorsed. According to the results, it can be concluded that negative beliefs about procrastination make students prone to test anxiety and academic procrastination. Therefore, modifying these beliefs can be considered as an intervention program to decrease test anxiety and academic procrastination.

Abstract
Mindfulness is one of the effective interventions in improving executive functions. Although this intervention is well documented for adults, but it is less addressed for children, while children with attention deficit / hyperactivity disorder Executive functions are problematic. The purpose of this study is to Designing, developing and validating a psycho-educational program of empowerment based on mindfulness-cognitive for reduce behavioral symptoms and improve executive function in children with attention deficit / hyperactivity disorder. The present study is of the fundamental type, which is in two parts, In the first for designing and development stages was a descriptive - analytic method with a configurative synthesis approach In the second stage For program validation, along with the use of face validity method, content validity method was used quantitatively and Qualitatively method with a panel of 10 experts and Content Validity Ratio (CVR) and Content Validity Index (CVI). The minimum and maximum CVRs for each item or component of the program were calculated as 0/73 and 1, respectively. Also the minimum and maximum CVIs for each item or component of the program were calculated as 0/80 and 1, respectively. Finally, the average content validity index (S-CVI/Ave) for the entire program was calculated as 0/91. This research leads to the preparation of an educational-therapeutic program in three sections: 1- basics, 2- external awareness and 3- internal awareness, which includes the sub-elements of strengthening attention, concentration, awareness of emotions, thoughts, tasks, purpose and impulses. Be. This educational-therapeutic program includes 16 sessions for children and 3 sessions for parents, 120 cards and 20 educational worksheets. The psycho educational program of empowerment based on mindfulness- cognitive for reduce behavioral symptoms and improve executive function in children with attention deficit / hyperactivity disorder has appropriate face and content validity, and has a useful validity for educational, clinical and research uses.

Abstract
The present study was conducted with the aim of the effects of segmentation and redundancy methods on cognitive load and vocabulary learning and comprehension of English lessons in a multimedia learning environment.The purpose of this study is an applied research and a real experimental study. The statistical population of the present study includes all people aged 14 to 16 who are enrolled in language schools in Damghan. The subject of the educational content was to explain the activity of volcanoes in the form of PowerPoint software in a maximum of 10 slides (based on the type of group) to 90 subjects who were randomly divided into six groups (15 people in each group). High segmentation / Audio presentation, High segmentation / Visual presentation, High segmentation / Redundant, Low segmentation / Audio presentation, Low segmentation / Visual presentation, Low segmentation / Redundant were assigned. The research was completely experimental (a completely random 2×3 factor design). Researcher-made test of vocabulary and comprehension learning, prior knowledge assessment and Pass Cognitive Load Scale (1992) were used to collect data. Analysis of variance was used to analyze the data.The results of analysis of variance showed that the interaction between segmentation method and redundancy method on cognitive load and learning was significant. The results of post hoc test also showed that the High segmentation / Visual presentation group reported significantly lower cognitive load and higher vocabulary and comprehension compared to other groups. According to the obtained results, it can be said that segmentation and redundancy methods are effective in reducing cognitive load and promoting English language learning in a multimedia learning environment.

Abstract
The objective of the present study was to compare the impact of two distinct educational approaches, namely the Montessori and robot-based methodologies, on students' executive functions. The research design was quasi-experimental, with two experimental groups and a post-test and follow-up. A total of 34 available female students from the second elementary grade were selected from the schools where Montessori classes were held. The students were free from physical or mental impairments and did not exhibit learning disorders. Each experimental group received one of the training methods in 12 sessions of 75-90 minutes. Following this, the post-test and follow-up were conducted using the Wisconsin tool to evaluate cognitive flexibility, the Stroop task to evaluate response inhibition, and the Cornoldi task to evaluate working memory. Multivariate mixed-variance analysis was employed to analyze the data. The findings of the study indicated a significant difference between the two educational approaches in enhancing students' executive functions (p<0.01). Additionally, the subscales of executive functions (as defined by Miyake, 2000) demonstrated significant differences, thereby corroborating the efficacy of the Montessori educational method in fostering cognitive flexibility and response inhibition. However, with regard to working memory, the robot-based educational method was found to be of greater importance. Due to the nature of the Montessori education method, which is based on fully targeted tools and activities, the above results are acceptable; Also, due to the sequence of programming in educational robots and the need to use previous information and pay attention to the previous stages of coding, the effectiveness of robot-based education is also acceptable.
