In this descriptive qualitative research with case study research strategy, the Iranian oil industry innovation system in the form of adopting a structural and functional approach (systemic approach) in depth and in its natural context from the perspective of the participants studied. Based on theoretical framework that includes five systemic components of innovation system, actors and relationships between them have been identified. In order to ensure validity of the structure, multiple information sources (interviews, observations and document analysis) is used. Also to achieve external validity, previous theories have been used as the initial theoretical framework of the research. The absorption and development of strategic knowledge and technologies of the oil industry was introduced as the main function of the system and three sub-functions identified for it. Identifying 29 existing structural and functional challenges from the perspective of experts has complemented the understanding of this system. Finally, policy proposals are presented.

The research field included 12 academic experts in E-learning at the University of Tehran through purposeful Sampling. The validity of qualitative data, based on the four criteria of Lincoln and Goba (1985) including; credibility, transferability, dependability, and confirmability and also reliability by re-coding and two coders have been examined and confirmed. The results of the analysis led to exploring142 main concepts, then in the form of 10 critical challenges related to the most components of the educational system including; learner, teacher, technology, financial and information resources, ethical considerations, university culture, classroom leadership, support system, learning effectiveness, and satisfaction of internal stakeholders. Finally, using a systematic approach, the mentioned challenges have been classified into three main dimensions of learning-teaching system such as; input, process, and output.
