Academic Paper from the year 2021 in the subject Pedagogy - Adult Education, , language: English, abstract: The study reflects an overview of MOOC research for higher education (HE) and professional development (PD). Massive open online course (MOOC) has attracted the attention of educational stakeholders. The phenomenon has been studied from various perspectives at different points of time. Though few researchers stressed the impact of MOOC HE, some remain skeptical about its relevance to school education. MOOC is even researched on PD. However, we believe that HE and PD go side by side. There is no water-tight separation between the two. Such an argument leads us to go for this systematic review which included 81 publications of different forms within the time frame of 2008-2020. Connectivism theory remained the backbone of this research. A mixed-method of research approach has been followed here. Content analysis and discourse analysis have been used to analyze the data. Significance and scope for future research have been incorporated.
