Abstract-The purpose of this study was to analyze 3D virtual worlds in terms of Connective Learning approaches with the direction of educational technology experts' opinions. Questionnaire with two sections and 6 items was used as data collection instrument. Within the context of the purpose of the study 30 participants who have 3D virtual world experience from different countries consulted through a questionnaire developed by the researcher. On this basis, features of 3D virtual worlds analyzed in terms of connected knowledge networks with the help of participant opinions. To the results of this study, the participants who have 3D virtual worlds experience strongly support that 3D virtual worlds and capabilities of these environments cover diversity, autonomy, interactivity, and openness features of connected knowledge networks. Also the participants who see themselves sufficient about technology usage more agree with 3D virtual worlds as connected knowledge network than who see themselves insufficient about technology usage. Some important suggestions presented as result of the research.Index Terms-3D virtual worlds, Connectivism, Connective learning environments, connected knowledge networks.
