Within the scope of this aim, 102 studies were reviewed with regards to some variables: most preferred keywords and words in abstract, year of publication, authors, journals, geographical distribution, academic disciplines, research methods, course delivery methods, participant type, and references. The findings demonstrate that the articles reviewed were from 216 authors in 20 countries. Most of the studies were from the Social Sciences field, and the continent with the most studies was North America. Quantitative research methods were mostly preferred in the studies, and the study group of a great of majority the studies were higher education students.
