The purpose of this study is to systematically analyze the causes of free-riding in team collaborative learning situations and explore practical solutions for various causes of free-riding. Data on the experiences of 270 students from universities in the Seoul metropolitan area who have undergone collaborative classes were collected regarding their experiences of free-riding. The data were reviewed through expert Focus Group Interviews (FGIs) to discuss and derive final solutions. The results indicated that it is important for instructors to detect free-riders early on and provide appropriate scaffolding tailored to the attitudes and characteristics of identified free-riders. In the proposed solutions, emphasis was placed not only on improving positive perceptions of collaboration during and after the collaboration process but also on maintaining team morale. Additionally, the study aimed to establish solutions through scaffolding based on factors related to early detection of potential causes and prevention of free-riding. It is hoped that the results of this study will serve as a helpful resource for instructors leading team collaborative learning in dealing with free-riders.
