The flipped classroom is one of the new approaches to learning and innovative teaching methods worldwide. Given the conditions created in the Corona pandemic and the production of the initial content of many courses, a practical experience of holding a flipped class is examined. Accordingly, the present analysis aims at assessing perceptions, experiences, quality of participation, learning performance and student satisfaction with in a flipped classroom. 18 students participated from the field of electrical engineering in this case study. The data were analyzed using statistical methods of one-sample t-test, Pearson correlation, regression coefficient, and SPSS software. The results revealed that students' access to information and resources and teachers' support and motivation significantly affected students' satisfaction. Furthermore, access to information and resources and teacher support and motivation significantly affected student-perceived learning outcomes. Finally, supporting students' participation and collaboration with each other in flipped classroom also had a significant effect on their satisfaction and perceived learning outcomes. The knowledge gained by students during the class had a significant impact on students' satisfaction and perceived learning outcomes.

The purpose of this case study was to measure satisfaction of some postgraduate engineering students at Shiraz University about virtual and remote laboratories. The participants were 18 electrical engineering students selected from Shiraz University through purposeful samples. The studied variables in order to measure the satisfaction of remote laboratories included students' focused attention during the use of the virtual laboratory (FA), perceived usefulness of virtual lab (PU), virtual lab approval by students (Confirm), students' satisfaction with the virtual laboratory(Satisfaction), fun and enjoyable virtual lab (Play), easily perceived by students in using a virtual lab (PEU), Attitude to the virtual laboratory (Attitude), tendency to use the virtual lab continuously (ICU), quality of virtual laboratory design (QD). Results revealed that students' satisfaction with the virtual laboratory was above the middle standard rating. Furthermore, from the students' point of view, the quality of the virtual laboratory had a significant effect on their "Satisfaction" with the virtual laboratory (Sig. 0.000, B = 0.885), and from the perspective of the students, the QD had a significant effect on ICU (Sig. 0.000, B = 0.937). Finally, the regression analysis showed that the QD had a significant effect on students' attitudes toward the virtual laboratory (Sig. 0.000, B = 0.885).

Abstract The present study is a qualitative research with a phenomenological approach that has been conducted to identify the dimensions and components of professional development of primary school principals and to develop its framework. The statistical population of the study was the principals of public primary schools in Tehran in the academic year of 2019-2020. In two stages of sampling, samples were selected by quota and then purposive sampling methods. Semi-structured interviews were used to collect data. The interview continued until the data exploration and data collection process reached a theoretical saturation point after interviewing 14 people. Data were analyzed by open and axial coding steps. Two methods of verifying the interviewees and verifying an external expert were used to control the validity. Two methods of verifying the interviewees and verifying an external expert were used to control the validity. To determine the reliability, two methods of reviewing the writings and also the method of recoding were used. The agreement was calculated in the coding homogeneity and the agreement coefficient was 86%. Findings showed that the professional development framework for primary school principals has 3 dimensions, 14 components with 117 indicators  Which includes : the content dimension of professional development (with components of general management knowledge, specialized management knowledge, interactive skills, resource management skills, professional skills, personal inclinations, managerial attitude, physical and mental ability and intellectual ability), the dimension of professional development process (with the components of self-development actions and developer relations) and the dimension of organizational requirements (with the components of knowledge acquisition and acquisition of skills, modification of selection and appointment methods of managers, improvement of organizational structure and processes).
