Yeah, the abstract could use a bit more work. The gist of it is being in a closed-loop cycle with ChatGPT only helps with the task at hand, and not with engaging with the full learning process. Instead they say "When using AI in learning, learners should focus on deepening their understanding of knowledge and actively engage in metacognitive processes such as evaluation, monitoring, and orientation, rather than blindly following ChatGPT's feedback solely to complete tasks efficiently."
