The main goal of the current research was to design a learning model using the characteristic of the structural approach in a blended learning environment in high school. This research is practical and theoretical in terms of purpose, and a qualitative and quantitative sequential mixed research method has been used. To do this research, the first question of the research was answered by studying and reviewing the available texts, documents and written sources and using the literature and research background and scientific sources. To answer the second question, Meyering and Delphi content analysis technique was used. In the first stage, the answer to the second question was obtained by using the qualitative study method, the content analysis technique of Meyering, and the desired components were extracted and used as a complement to the Delphi method. In the second stage, a panel of participants was formed using the snowball sampling technique, and the relevant experts were selected, and after presenting various questionnaires and conducting interviews, the desired components and indicators were selected and confirmed by the experts.Next, to answer the third question of the research, in order to validate the designed model, the Reigeluth questionnaire and Cronbach's alpha were applied to measure its reliability.Also, Kendall's coefficient of concordance was used to determine the level of consensus in the Delphi method. In order to check the content validity, the index model (CVI) was used and to determine its general suitability, (S-CVI) applied, and finally, based on the results and taking into consideration the corrections and suggestions of the professors, the final model was designed and approved.

The purpose of this study was to determine the effectiveness of web-based distance learning model in the context of a constructivist learning approach on learning performance, satisfaction and attitude of Payame Noor Sardasht students. The research method was quasi-experimental with pretest-posttest design. The statistical population of the study included all students of Payame Noor University of Sardasht who selected 45 people as the research sample, using Morgan table and cluster sampling method. Of these,15 students were assigned to conventional distance education group, 15 to the distance education group based on reproductive learning, and 15 to the project-based group. Data collection tools included a teacher-made test to measure learning performance as well as a researcher-made satisfaction and attitude questionnaire that the content validity of the teacher-made test was reviewed and approved by professors. And its reliability through splitting method was 82% in pre-test and 85% in post-test using Spearman-Brown formula. The content validity of the satisfaction questionnaire and the attitude questionnaire were reviewed and approved by experts and the reliability of the satisfaction questionnaire was 84% and the attitude questionnaire was 80% using Cronbach’s alpha. Data analysis was performed using inferential statistics and one-way analysis of variance. Emphasizing the research findings, it can be claimed that both web-based distance learning models have a positive effect on students learning, satisfaction and attitude. Based on these findings, it can be concluded that these two educational models (project-based learning and reproductive learning) have a great impact on increasing students’ learning performance, satisfaction and attitude.

This research aimed to study the relationship between learning styles among two groups of electronic and traditional students in PAYAM NOOR University and its relationship with the satisfaction. The research method was descriptive and co relational research. The study population included all male and female master students of electronic (virtual) (N=1400) and traditional (N=1600) courses of PNU in 1395-1396.Using Cochran formula, the estimated sample size of students for traditional and electronic courses were equal to 310 and 302 respectively (totaled 612). The sample size was selected by stratified random sampling method with proportional assignment. In order to collect data, Kolb (1999) learning styles questionnaire and Bahrani and Jokar (1378) critical student satisfaction questionnaire were used. For both, traditional and electronic groups, between learning styles (convergent, divergent, assimilator and accommodator) and satisfaction, there was a significant relationship. The results showed that in the traditional course converging, diverging, assimilator and accommodator styles have the highest relationship with the academic satisfaction. In electronic courses, divergent, assimilator, and convergent styles have the most relation to academic satisfaction. The study of the status of learning styles in the electronic group showed that the convergent learning style with (14.57%), has the least frequency, divergent with (30.79%) has the highest frequency, the assimilator style has (28.14%) and the accommodator has (26.49%) frequency. Regarding the status of learning styles in the traditional group, convergent and accommodator style have the least frequency and the assimilator learning style has the most frequency. In terms of quality assessment, most students were not satisfied with the traditional courses and in contrast, the electronic group had more academic satisfaction.
