Purpose: The present research aimed to designing a teaching pattern from students’ lived experiences of the teaching process in universities of Iran in technical and engineering disciplines. Methodology: This study in terms of purpose was applied and in terms of implementation was qualitative from type of phenomenological. The study population consisted of postgraduate and PhD students in technical and engineering disciplines of Australian universities (Melbourne, Monash and Swinburne) in 2018 year who had the experience of studying at the undergraduate and graduate levels in Iran country. The research sample according to the theoretical saturation principle was determined 10 people who were selected by purposive sampling method. Data were collected through semi-structured depth interview method which its validity was confirmed by the method of reconstruction of reality and its reliability was confirmed by conducting interviews in a quiet and unbiased atmosphere and to analyze data used from thematic coding method. Findings: Findings showed that students’ lived experiences of the teaching process in Iranian universities in technical and engineering fields had 197 initial concepts and 38 final concepts in 3 main components: professor (23 concepts), student (7 concepts) and content (8 concepts). Also, based on the concepts and components derived from the students’ lived experiences of the teaching process, the teaching model in technical and professional fields was designed and approved based on the opinion of experts. Conclusion: According to the results, planners and officials to design curriculum and professors to improve their teaching can use the teaching model designed in this research to improve the quality of education in universities.

Purpose: The purpose of this current research is to design and formulate a decentralized curriculum for primary schools in Iran. Methodology: The methodology is qualitative research from content analyzing of comparison-categorizing system, which includes three steps. In the first step, decentralized and extracting its parameters, international dissertations and researches in connection with subject of the research in qualitative analyzing method were investigated and studied. In the second step, after concluding the findings, the final curriculum pattern was formulated including decentralized curriculum (objectives and contents, teaching-learning methods, evaluation). In the third step, measuring-descriptive methodology was used by making use of factor-analysis for evaluating the credibility of suggested model from viewpoints of experts and specialists. The realm of research was all books and written references on decentralized curriculum that were selected by purposeful sampling. Due to the abundance of various available printed and digital references, those ones from 2000 to 2015 were used. Data collection tools were researcher-made charts and tokens, which were used for collecting categories and elements of decentralized curriculum. Faculty members, specialists and experts’ viewpoints were used for reliability of the research. Findings: The After taking opinions and revising, the final framework was formulated. For increasing the credibility of the research, ultimate attention and care were taken in order to prepare tokens. On quality of research, 467 conceptual codes were extracted, 23 main parameters were achieved which were used for formulating decentralized curriculum. A research-made questionnaire was designed in order to evaluate the conceptual structure of the research and it was reviewed by 200 specialists and experts, and then it finally was approved after carrying out a factor-analyzing showing that most of articles had proper weigh-factor which means all standard coefficients were within 0.3 to 0.6. On the other hand, the articles put proper weigh-factors on their factors. Conclusion: This current research as a non-intensive curriculum model for Iranian elementary schools is usable for curriculum designers and authorities of Ministry of Education who have stepped forward efficiently to give more authorities to education organization of provinces.

Purpose: The aim of the present study was to identify the causes of social isolation and design a relevant model for high school students. Methodology: This was an applied study in terms of its aim and mixed-method study in terms of its implementation method (qualitative and quantitative). The study population in the qualitative section included documents and resources and educational management experts and, in the quantitative section, 180 female high-school first-year students in Gorgan during the academic year 2019-2020. According to the data saturation principle, the research population in the qualitative part included documents and resources related to social isolation and 10 educational management experts who were selected by purposive sampling.
