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.

The aim of this research was to investigate the effectiveness of mental imagery on the English language comprehension of sixth grade students. The method is semi-experimental and its plan involves pretest, post-test, and follow-up. Using a multi-stage random sampling method, 32 students were selected from schools in the district (2) and assigned to either the experimental or evidence group - each group consisted of 16 students. All the students within both groups were given a pretest which consisted of 20 multiple choice questions (with 4 possible answers each). There was no significant difference between the mean scores gained by the students of both groups on the pretest. The experimental group received the mental imagery teaching program and how to form pictures in the mind-e.g, how to visualize-before reading, while reading, and after reading a short story, for example, by being requested to draw pictures of the characters, scenes, or setting in the story as they perceived them. The evidence group received no instruction. To measure the effectiveness of the treatment program for each experimental condition, a research-made reading comprehension test was applied. There were  significant differences between the experimental and evidence groups, when data analysis was performed by ANOVA, using repeated measures. The findings showed that the mental imagery teaching program can improve the English language comprehension and this study suggests that the English teacher may improve her teaching strategy by optimizing the use of a variation technique in school. The teacher should be creative while delivering materials in the class.

The basic aim of this research is from universal school-based management model to pattern Iran's progress - Islamic schools Board of trustees: qualitative analysis dimensions and specific indicators to evaluate performance. According to the study, functional and in terms of subject matter and the nature of the research component of the combination is mixed. In the first phase of this study, grounded theory as a qualitative approach was used and secondly from the descriptive - survey has been used as a quantitative approach. The statistical population of the study included 12 experts, policymakers and experts in the ministry of education, and in the small part, all teachers and principals of the board of trustees of five provinces (Tehran, Isfahan, Mazandaran, Khuzestan and Semnan) during the school year 2015-2016, they were employed. Due to the high number of these schools, ten managers and teachers were selected from each province based on the Krejsi-Morgan's table of 234 people (184 teachers and 50 managers) by random sampling method and selected a researcher-made questionnaire with 140 items (with Cronbach's alpha = 0.901), which was compiled based on the categories identified in the qualitative section were responding. To ensure validity, the questionnaire was examined by university professors and several key experts in education. The qualitative data research through systematic project-based coding process grounded theory of Strauss and Corbin were analyzed. In the quantitative analysis of data gathered from structural equation modeling confirmatory factor analysis was performed using SPSS and Lisrel. The results of the qualitative research findings showed that 12 indicators were identified as the main components and 38 sub categories that were identified in the assessment of the performance of the schools of the board of trustees based on the comprehensive school-based management model. The findings of the quantitative research have also shown that the two components had the greatest impact on the board of trustee's schools. P Participation with path (0.69), organizational commitment with path (0.65), flexibility with path (0.62).
