In this paper, the effect of space environment factors on the number of accidents in Tehran and Alborz provinces has been investigated. Spatial environmental factors include cosmic rays and solar activities that have direct and confirmed effects on industry, agriculture, telecommunications, etc., and these factors may affect human mental health. The main purpose of this article, which is the motivation of this research, is to investigate the effective factors of space environment on human mental health, assuming that the increase or decrease of accident rates is directly related to it. Therefore, daily statistics of urban and road accidents in Tehran and Alborz provinces from 1393 to 1397, along with parameters measured by ground-based observatories of spatial factors, including the daily values ​​of cosmic radiation activities, sunspots, radioactivity. At a frequency of 10.7 cm and solar magnetic parameters were collected and then the correlation of spatial factors with the number of accidents was evaluated.The results showed that cosmic radiation after 177 days with a correlation coefficient of 0.46 and sunspots and radio flux of 10.7 cm after 62 days and 74 days with a correlation coefficient of -0.55 and -0.48, respectively, affect the number of accidents.

The aim of the current research was to analyze the content of the textbook of experimental sciences in the second year of elementary school 1400-1999 in terms of the active or passiveness of the text, questions and images.In this content analysis, the unit of analysis was sentences, questions, and pictures.Due tolimitedness of the statistical population, which included experimental science books of the fourth, fifth, and sixth grades, the sampling method was not adopted and the entire statistical population was selected for analysis The data collection method was analyzed under the title of experimental science books of the second elementary school with reference to William Rumi's method, and descriptive statistics were used to analyze the data.The results obtained for the fourth book are as follows that the text, images and questions were active and dynamic according to the findings.The results obtained for the fifth book are as follows that the text, images and questions were active and dynamic according to the findings.It was dynamic.The results obtained for the sixth book are as follows that the text and images are considered active and dynamic according to the findings.The questions also show that the questions are inactive according to the engagement coefficient.

This research aimed to investigate the advantages and disadvantages of e-learning of laboratory units in the chemistry education field of Farhangian University during the outbreak of the Corona virus. The research is applied and has been done using quantitative and qualitative methods. The statistical population was all the student teachers, as well as all the chemistry professors of Farhangian University who had the experience of educating chemistry laboratory units in face-to-face and virtually. 180 student teachers and 14 professors participated in the research. The research tool was two researcher-made questionnaires and three open-ended questions. The content validity of the questionnaires was confirmed by 3 faculty members of Farhangian University. The Cronbach's alpha coefficient was 0.87. The biggest disadvantage of the e-learning of chemistry laboratory units from the perspective of participants was the lack of practical skills. The biggest advantage was saving time, reducing purchasing costs, reducing the consumption of chemicals, less environmental pollution and greater safety. Most of the participants considered the only way to compensate for the shortcomings of e-learning of laboratory units is to hold these units in face-to-face. No significant difference was observed between male and female professors and also among students by entry years and gender.

The purpose of this research is to investigate the effect of role-playing education on the learning rate and motivation of the biology lesson compared to the traditional and teacher-centered method. This research was conducted with the method of pre-test and post-test in two experimental and control groups and the results were compared. The statistical sample of the research included all the experimental 11th grade boys in Morvdasht city. One high school was randomly selected from among the boys' high schools. This high school had 2 eleventh grade classes and 60 students. These two classes were randomly divided into experimental and control groups. Using the half-year grades of the biology course as a pre-test, the difference in the significance level of the two experimental and control groups was examined. The method of playing a role in the topic of hormones was carried out in the experimental group. No action was taken in the control group. A post-test was taken from both groups. The results of the research showed that the students of the experimental group had better grades and more complete and conceptual learning, showing a significant difference. Therefore, the role-playing teaching model can be implemented in biology topics.

The entanglement classification of quantum states is nearly related to the positivehomogeneous function that is invariant under stochastic local operations and classicalcommunication (SLOCC) transformations. In this paper, first we give a general schemeto measure the N-tangle as an entanglement measure of an arbitrary odd-N qubit purestate. Then we develop a classification algorithm that is based on the integration betweencompetitive learning and the computational power of quantum computing. Using thisalgorithm the entanglement measure we classify an input into one of two binary classeseven if the input pattern is incomplete.The entanglement quantification and classification of quantum states of a large number ofparticles becomes quickly complex. This major challenge was raised within the quantum information science regarding the physical phenomenon of entanglement as a key resource. Duringthe past years, the polynomial invariants such as concurrence for two-qubit states andthree-tangle for pure three-qubit states was defined

Heat transfer, which is the movement of heat across the boundary of the system due to the temperature difference between the system and its surroundings, is a well-known phenomenon in everyday life. When cooking or insulating houses, people use the related concepts without knowing the physical principles of this phenomenon. Heat transfer is intuitively related to material properties, that is, to the physical concept of heat conduction. Despite the simplicity of the concept, heat conduction is usually difficult to measure. In this article, a simple, fast and practical method is introduced that gives completely accurate values for the coefficient of thermal conductivity of insulating and semi-insulating materials and is suitable for teaching this concept and implementing it in a classroom environment.

The purpose of this research is to review the experiences of researcher, teachers, and valuable professors and model them in order to determine the ideals and professional commitments for the future of the author's teaching. The research method is narrative research which was done by extracting data through coding the writer's lived experiences and analyzing the data using thematic analysis method. The findings of the research showed that according to the author, family approval, job security, interest in teachers and teacher's job are important factors for entering Farhangian University. Also, despite the lack of university facilities and the shortcomings of the curriculum, Farhangian University is at a very favorable level in terms of paying attention to the values and interactions of human factors. Creating transformation in the educational system is one of the main goals of the author and striving for lifelong learning is one of her commitments. Examining the results of this research can make students interested in the field of mathematics education as well as the growth and development of the teaching profession.

In the student internship course, teachers should use their theoretical knowledge in the classroom in a practical way. Internship courses will have an effective role in the professional growth and preparation of student teachers of Farhangian University in various fields. In the internship course topics, especially the 3rd internship of Farhangian University, the main emphasis is on action research and teaching based on the constructivist method (E5). The investigations show the failure to achieve the set goals and the results and realization of the student teachers' lesson plan. it was tried to investigate the obstacles to the implementation of the constructivist teaching method (E5) by the students .After the observations of student teachers in schools and their teaching, which took place in both face-to-face and virtual form, these obstacles were categorized in different levels of university, school, professor, student teacher, guidance teacher, program. In order to remove these obstacles, suggestions such as adding a lesson unit of principles and modern teaching methods to the curriculum of Farhangian University, institutionalizing the work group method in the existence of students from the beginning in schools, holding annual meetings for teachers to think together for better implementation of teaching methods .

Today, the STEM educational approach has become a global movement. Life in this century requires a series of skills that can be achieved through STEM. This educational approach eliminates the gap between theory and practice and is a kind of integrated combination of four fields of science, technology, engineering and mathematics. In this method, the teacher plays the role of a guide and unlike the traditional method of the teacher, he does not dictate science to the learners. Also, this method requires the active participation of learners. In the conducted studies, it has been determined that this educational approach improves learning in students. Because it prepares learners to solve problems in the real world. Today, the advanced countries of the world are implementing this educational approach in their educational centers such as schools and universities, and they have even established special centers for the implementation of this educational approach and are spending a lot of money on this. According to the research conducted in this field, it seems necessary to equip the country's educational system with this educational approach. Today, what is desirable in educational systems is the integrated and comprehensive education of learners and students (Motahri-nejad, 2015).
