<p dir="ltr">This dataset was collected as part of the research project <i>Generative AI in Collaborative Learning: Exploring its Impact on Cognitive and Metacognitive Interaction</i>. The study investigates how students engage in group discussions with and without the use of generative AI tools, focusing on the ways cognitive and metacognitive interactions are shaped in these learning environments. The dataset contains 1,044 rows and 5 variables, which include group identifiers, indicators of generative AI use, system-recorded timestamps, students’ utterances (including sentences revised through large language models), and the corresponding cognitive/metacognitive interaction codes. Together, these data provide a structured record of group-level learning processes and enable the analysis of patterns in student interaction, offering insights into the role of generative AI in collaborative learning.</p>
