A systematic review of research related to the blended teaching-learning approach in Iranian universities

The purpose of this research is to investigate researches relatedto the blended teaching-learning approach in Iranian universities. The research method is applied, and data collection was conducted using a qualitative approach through a systematic review method. For this purpose, resources were searched from databases(sid, noormags, magiran, civilica, ganj.irandoc) by using related keywords.Then the found documens were analyzed based on Sandlowski and Barroso seven-step model.Based on a comprehensive and systematic view, the research results indicate that the previous researches on the subject of the blended teaching-learning system in Iranian universities have examined the three dimensions of the input(competencies related to students with 5 subdimensions, competencies related to instructors with 2subdimensions), the process(teaching-learning process with 3subdimensions) and the ouput(student-related output with 3subdimensions, instructor-related output with 2subdimensions) as the main dimensions of this approach.Based on the findings, the role of university management and leadership has been neglecte in the studied researches,while it is one of the main dimentions of the teaching-learning system.The results of the present research can be a model for university managers and instructors to effectively implement a blended approach in the teaching-learning system,and a guide for researchers to conduct further research in order to eliminate research deficiencies in this field.
