Purpose: The aim of this study was to design a combination learning model in technical and vocational education. Methodology: This study was applied in terms of purpose and exploratory (quantitative and qualitative) in terms of implementation method. The research population was in the qualitative part of documents and resources and specialists in the field of combined learning and in the quantitative part were the principals and students of technical and vocational schools in Zanjan province in the academic year 2018-19. The sample of research was in the qualitative part of documents and resources related to combined learning and 17 experts in the field of learning who were selected according to the principle of theoretical saturation by sampling method of network experts and in the quantitative part were 176 administrators and students who according to Krejcie and Morgan table with Cluster sampling method was selected. Data were collected by filing methods, interviews and a researcher-made questionnaire (39 items) whose face and content validity of the questionnaire was confirmed and its reliability was obtained by Cronbach's alpha method of 0.81. Qualitative data were analyzed by open and axial coding method based on Klein model and quantitative data were analyzed by Delphi methods to determine the validation of the model and t-test. Finding: The results showed that combined learning in technical and vocational education included 43 basic concepts and 9 structural concepts including learning objectives, learning content, learning activities, learning strategies, grouping, learning materials and resources, learning time, learning location and evaluation. The combined learning model of design and its validity by experts with Delphi method was approved in two stages and the number of basic concepts was reduced from 43 to 39. The results of t-test also showed that technical readiness and readiness of human factors combined learning had an effective role in technical and vocational education. Conclusion: According to the results, the designed model of combined learning approved by experts can be used in combined learning environments in technical and professional organizations and can be a criterion for future research in this organization.

Learning of students. This study, in terms of purpose, applied, and in the manner and method of implementation, is an integral part of empirical studies. In this research, a four-group Solomon design with pre-test and post-test, and control group were used. The statistical population consisted of all undergraduate students at Kermanshah Payam Noor University, who had specialized  language lessons during the semester. Among them, 60 people were selected as the statistical sample using available sampling. To test the students' learning, a researcher-made test was used. The validity of the test using the Kooder Richardson method was 82. announced. SPSS software was used to perform statistical calculations, and multivariate analysis of variance analysis was used to investigate the hypotheses of the research. The results of the data analysis showed that there is a significant difference between the mean scores of the experimental and control groups in the visual, written, audio, and oral components, but the effect of the pre-test, as well as the interaction of pretest and group is not meaningful. The results also showed that the participation of learners in training exercises, while paved the way for activating knowledge of learners' resources, helps them to associate past and future. These findings ultimately confirm the impact of multimedia education on the level of learning the student's English language vocabulary, and can be used in conjunction with other intervening methods. 

Textbooks are the most important forms of media in open and distance universities. As a result, they should have features that enable the distance learners to attain in-depth learning without the presence of an instructor. This study aims to design a comprehensive model for open and distance university textbooks through analyzing the textbook concept using the hybrid model. In the initial stage, a review of literature up to 2011 was done (119 cases) using several databases.  Then, a field study was carried out by assessing 2 textbooks from open universities of England. Finally, data collected from the two previous stages were analyzed and evaluated, using Strauss and Corbin's method, and a proper model was proposed for open and distance university textbooks.
