The network visualization consists of several circular, color-coded nodes distributed into distinct cluster groups. On the left and bottom sections, a large red cluster features prominent node labels such as “study”, “assignment”, and “project” as major hubs, surrounded by closely linked terms like “motivation”, “perception”, “faculty”, “value”, “classroom”, “author”, and “case study”. To the upper-middle region, a green cluster highlights a large central node labeled “educational resource” along with smaller connected nodes such as “adoption”, “instructor”, “activity”, “term”, and “quality”. On the right side, a dense blue cluster contains key nodes including “higher education”, “teacher”, “paper”, “learner”, “content”, and “educator”, mapping out an intricate web of educational terminology interconnected by curved lines. In the bottom corner, a small “V O S viewer” logo sits on the left.Co-occurrence network map of terms found in titles and abstracts
