science education

This paper studied Iranian Physics education students’ understanding of the nature of science. The research is descriptive and was conducted through a survey study method. The sample of our study consisted of 94 students of Physics education in the second and third year of university. They were selected through random sampling from four classes at Isfahan University and Shahid Rajaee Teacher Training University in Iran. For this purpose, 24 statements of the SUSSI questionnaire (Student Understanding of Science and Scientific Inquiry) were translated into Farsi. The statements were randomly arranged to form a new questionnaire. The validity of the new questionnaire was examined and approved and the Cronbach's alpha of the questionnaire was calculated as 0.738. In the data analysis phase, the mean score of each statement was calculated using the frequency and the numerical value of each response. The score of each component of the nature of science was determined by averaging the scores of the statements related to that component. The average score of each component expresses the formal or naïve or transitional view regarding that component. According to the results, while our subjects’ attitude to observation and deduction conformed to international standards of science education, they had some misunderstandings regarding the other components of scientific inquiry. As physics education students will become teachers and contribute to the future generation's view of science, it would be better to incorporate more educational activities into teacher education programs with the aim of improving the trainees’ conception of science.

This study is investigated the effectiveness of science education with STEM approach, in a combined (face-to-face and virtual) method, on problem solving skill of the students of the middle school in the topic of energy. This research is a semi-experimental and pre-test-post-test type with the control group. The statistical population is all the 7th-grade male students from middle school in Tabadakan region, Mashhad 2021-2022. From this statistical population, 70 students were selected by the convenience sampling who were in two classes. One of the classes was randomly selected as the experimental group and the other as the control group. The control group received training through the traditional approach, whereas the experimental group underwent training using the STEM method. The research tool was Hepner and Patterson's (1988) standard problem solving skill questionnaire. In order to develop lesson plan with STEM approach, the proposed standard framework (STE(A)M IN INTEGRATED LEARNING SCENARIO) was used. Data from questionnaires was analyzed using SPSS, with statistical indicators calculated and normality. Also, hypotheses investigated using Kolmogorov-Smirnov tests and covariance analysis. The significant values obtained for problem-solving skill (0.033) and its subscales, including Confidence (0.022), Approach-Avoidance style (0.046) and Personal Control (0.025), indicated that the STEM approach was helpful in improving learners' learning and strengthening their problem-solving skill. Also, this study showed that students generally have difficulty learning scientific concepts and problem solving skills, but hybrid approaches such as STEM can improve educational processes and learner performance in developing countries such as Iran. Therefore, the role of STEM approach in education becomes highlighted.

The aim of designing the education spaces is to providing the required spatial relationships for education processes. It means that the spaces and equipment which are required in every field, how and by the which discipline thy have been arranged to offer the final aim of education in advance, is the achievements of providing the education spaces management. The purpose of study is to evaluate the status of science and technology education spaces in management of providing the space and educational equipment for schools in fundamental evolution document Iran Education. In this survey, the research method is content analysis and it is descriptive in regards to practical purposes and collecting the data. The statically population for this research is the Iran Education Fundamental Evolution Documents, the criteria and standards for designing the educational spaces and documents about the education history. According to the results, evolution in the providing the spaces for educating the science and equipment adaptation with day technological infrastructure are crucial. The recommendation for reviewing the status of educating the science and technology and symmetry of facilities with the need to the space and equipment for educating science and technology in the system of management of providing the space and equipment in compliance with local culture and todays and future technological needs and attention to the extension of garden school model was discussed.
