Methods In this study, qualitative content analysis: inductive approach to the study of specialized information in a anchoring instruction, relevant data to answer the research questions were provided. approach is constructive. Despite similarities, anchoring instruction with problem-based learning, in the kind of problem solving process, the tools used to collect data is together different. The anchored instruction approach is an attempt to help students become more actively engaged in learning by situating or anchoring instruction around an interesting topic. Anchored instruction emphasizes the need to provide students with opportunities to think about and work on problems, which is an emphasis of cognitive constructivists. Anchored instruction also emphasizes group or collaborative problem solving, which is an emphasis of social constructivists. anchoring model based on constructive principles presented in this study, can be a good practice guide for instructional designers and teachers.

The purpose of of this study is evaluate the effect of multimedia in environmental education in comparison to traditional teaching environmental education to school children.

The statistical sample of 44 students randomly into two groups (1 control and 1 control group) were selected. Data were collected, which is calculated after determining the validity and reliability (92/0) was conducted. Data were analyzed using descriptive and inferential statistics. The results from the questionnaires showed that the level of significance for changing the knowledge, attitudes and behavior of environmentalists smaller than / 05 is obtained. As a result, the study's assumptions on the effectiveness of multimedia teaching environmental education to be confirmed. .

The purpose of this study is to investigate the effective and inhibitory factors in establishing a thinking environment in Iran's national curriculum.This qualitative research is based on grounded theory approach and is used for semi-structured interviewing tool. The population of the present study is composed of experienced teachers in primary education in the provinces of Tehran, Khuzestan, Ardebil and Isfahan. 17 teachers were selected by sampling method based on saturation principle and interviewed.The results were obtained in three stages: open (primary), axial and selective (selective) coding. Open codes, including 26 core concepts and codes, also include six major categories, including the analysis of life issues, theology, self-knowledge, educational factors, deterrent factors, and cognition of nature. Studies have shown that although experts have been struggling to move the educational system and have certainly faced a lot of problems in establishing a thinking-based approach, unfortunately, successful implementation of the barriers, such as lack of adequate and timely information, the gap between parents and students, lack of financial support, Teachers' attitudes and parenting attitudes.

The aim of this study was to determine the effectiveness of cognitive computer games on the working memory of children with high-functioning autism disorder. The research method was semi-experimental with pre-test post-test design with control group. The statistical population of this study included all children with autism disorder 9-12 years old in Tehran's educational, therapeutic and rehabilitation centers in 2018. Out of the target population, 12 boys with high functioning autism disorder were selected by sampling method based on the Autism Spectrum Screening Questionnaire (ASSQ) (1999). They were randomly assigned into two groups of experimental group (6 subjects) and control group (6 subjects). Initially, both groups were evaluated by Cornoldy working memory test. After that, the experimental group received cognitive computer games in 12 sessions of 40 minutes in 4 weeks. At the end, both groups were re-evaluated. Data were analyzed using covariance analysis. The findings of this study showed that cognitive computer games improve the working memory of children with high functioning autism disorder. Hence, cognitive computer games can be used as an effective interventions to improve the working memory of children with high functioning autism disorders.
