The purpose of this study was to Survey Barriers to use of active teaching methods and techniques In the process of teaching -learning and providing solutions. The research method is descriptive-survey. The purpose of this study is practical and field research. The statistical population of this study consisted of all primary school teachers in Tehran's 14th district in the 2018-2019 academic year, which was 694 people. According to the size of the community and according to the table of Krejcie and Morgan, the number of research samples Selected 248 people. Research data collection tool was an Barriers of active teaching questionnaire. Descriptive statistics were first used to analyze the data and Then, according to the nature of the research hypothesis, the Kolmogorov-Smirnov test, the Friedman test and the single-sample T test were used. The result showed that Barriers to use of active teaching methods and techniques Including: Teachers' lack of mastery, Weakness in educational communication, Inadequate training space, Inadequate textbook content and Lack of educational facilities affect the process of teaching –learning and Friedman's test results also showed that there is a significant difference between the priority of research variables in all five factors. All factors were above average and Accordingly, the factor of weakness in establishing educational communication had the highest priority and the factor of lack of mastery of teachers had the lowest priority. Based on the results of the research, it can be said that these factors prevent the implementation of active teaching methods the teaching-learning process.

IOT has many applications in educational disciplines. With this technology, access to educational information will be increased. Digital content is also more easily shared between teachers and they can share information, share their knowledge and experiences with others. The main purpose of this study was to identify and rank the factors affecting the success of IoT in elementary education using Delphi and AHP techniques. The present study is applied in terms of research purpose and mixed method research through subsequent exploration in terms of research topic and questions. The data collection tool consisted of an expert questionnaire which was graded on Saati scale. The statistical population under study in this study was experts and experts in elementary education. From the snowball sampling method 14 people were selected as statistical sample. Excel software was used for data analysis. The results showed that smart phones and tablets with a normal weight of 0.254 were the first priority. Interactive learning with a normal weight of 0.161 comes second. Transforming communications with a normal weight of 0.158 is the third priority. Managing weight with a normal weight of 0.145 is the fourth priority. Social networks with a normal weight of 0.114 rank fifth. E-books with a normal weight of 0.112 are in the sixth priority. Toys with a normal weight of 0.056 are in seventh priority. Given the inconsistency rate of 0.05 in this ranking, there is complete compatibility between the pairwise comparisons of the models.

One of the most common learning disorders among students is spelling disorder, which accounts for one-third of all learning disorders. Therefore, the present study was conducted to investigate the effectiveness of flashcard training on improving spelling learning disabilities. The study was experimental with pretest-posttest design with control group. The statistical population of this study was all male elementary school students in Yazd city. The available sampling method used to select the sample. Thus, among primary school students who were enrolled in treatment and education centers for children with learning disabilities because of their spelling and learning disabilities; Spelling, 9 or lower, was selected, and replaced at random in the experimental (n = 20) and control (n = 20) groups. The students in the experimental group taught during the fourteen sessions, sixty minutes (three sessions a week), using flashcards, the most important and most used words and first elementary words.The control group trained using the direct method. Multivariate covariance results showed that flashcard training significantly improved written spelling impairment in first grade elementary school students in all two dimensions of visual memory, and educational problems. Therefore, integrated flashcards can be used to treat students' spelling disorder.

The purpose of this study was to investigate the relationship between the use of computer games and executive functions in children aged 5 to 6 years old in Karaj 4th district. A sample of this study included 31 and 30 pre-school boys who were selected and tested availability. The test was performed using a researcher-made questionnaire on the use of computer games. Then, through the Coolidge test, the executive functions of pre-school children were examined. Pearson, ANOVA and t test were used to obtain data. The results of this study showed that there is a direct and significant relationship between the amount of computer games used and the executive functions (p <0.05). This result was obtained by Pearson test. Also, using Pearson test, the relationship between the rate Using computer games with decision-making function is a meaningful program for preschool children that shows a moderate correlation (p <0.05), but there was not a significant relationship between the amount of computer games used for organizing and inhibition. (P> 0.05); also, using t test, the difference between the group was There is no use of computer games for girls and boys, and at the end of the one-way ANOVA test, there is not a meaningful relationship between the amount of history of using computer games with pre-school children's executive functions (p> 0.05).

The purpose of this study was to analyze the experience of preschool teachers about the impact of cyberspace on children's health. This study was a qualitative study based on a descriptive phenomenological approach or lived experience. The study population consisted of all preschool teachers in Tehran. Samples were selected using purposive sampling method and data saturation was obtained after seven in-depth semi-structured interviews. The text of the interviews was analyzed using Colaizzi's seven-step method. The findings of this study showed 60 semantic supportive units that were divided into four sub-themes (physical health, mental health, social health, and spiritual health) and two main themes (cyberspace opportunities and damages for children's health). According to the findings of this study, it is clear that cyberspace damages for children's health are more than its opportunities. Also, cyberspace has not been able to provide a good opportunity for children's spiritual health.Also, cyberspace has not been able to provide a good opportunity for children's spiritual health.

The purpose of this study was to determine the effectiveness of computer educational game on improving the understanding of mathematical concepts of students with specific learning disabilities in the third baseline. In this study, 23 students with math learning disorder were selected from the statistical population of the male and female students of the 3rd grade elementary school in the city of Mianeh (1265 people) after performing KeyMath and reiven matrix tests. They were then randomly assigned to both experimental and control groups. The experimental group was individually trained for 10 sessions of 30 minutes, under the supervision of Misha and Kousha computer games. But the control group used only regular school education. The results showed that the mean scores of the experimental group was significantly higher than the control group. So based on this study, we can conclude that educational computer games can improve the understanding of mathematical concepts (basic concepts, basic operations and function) in particular students with learning disorders associated with defects in the math.
