Exploring the Relationship between Online Interaction Measures and Problem-Solving Skills Through Social Network Analysis–Through Online Case Discussion Supported by Role Scripting

Online discussions in case-based instruction (CBI) are effective in developing the problem-solving skills of pre-service teachers (PSTs). Both the content-oriented role script and the communication-oriented role script have been proven to be of benefit to structure and to facilitate online discussions; however, which role script is more effective for online case-based discussion remains unknown. This study compares the effects of different types of role scripts on the problem-solving skills and engagement behaviors of 36 teacher trainees through two rounds of online case discussions based on the lens of social network analysis. The results indicated that content-oriented role scripts were more effective in improving teacher trainees' problem-solving skills through online case-based discussions. Whereas there was no significant difference in facilitating teacher trainees' participation and response to case-based online discussions. The findings provide empirical evidence regarding the design and implementation of role scripts for effective online case-based discussions.
