摘要：Group discussions can help students have a more effective problem-solving process because students exchange ideas and understand the provided problems. Accuracy in solving problems can be observed from students' knowledge and metacognition. This study used the descriptive qualitative approach to describe the characterization of students' metacognition during their interactions in positioning expert students, facilitators, and beginners. Problemsolving in group discussions is very helpful in bringing up students' metacognitive activities because they do not use only self-metacognitive but also social metacognitive.
