摘要：Instructional activities based on online discussion strategies have gained prevalence in recent years. Within this
context, a crucial research topic is to design innovative and appropriate online discussion strategies that assist
learners in attaining a deeper level of interaction and higher cognitive skills. By analyzing the process of online
discussion in depth using a specific instructional strategy, we may discover the characteristics and limitations of
this strategy. This case study utilizes an online discussion activity adopting a role-playing strategy in a college
course and conducts an empirical analysis to explore and evaluate both the content structure and behavioral
patterns in the discussion process. We propose and adopt a new method of multi-dimensional process analysis
that integrates both content and sequential analysis, whereby the dimension of interaction and cognition are
analyzed simultaneously. Furthermore, we discuss the patterns, characteristics, and limitations of the roleplaying
discussions and provide suggestions as references for teachers who utilize online role-playing discussion
activities.
