Thank you for posting this Julian, as this is an excellent topic for discussion pertaining the student's use of AI in their assignments.
It's interesting you note the study that the majority (80%) of the students utilize a LLM platform for comprehension - rather than "higher order critical thinking tasks".
I believe it is the instructor's role to present the coursework in such a manner that it directs the students to utillize their critical thinking skills say for instance in analyzing a case study or presenting options to solve a problem encounterd by a business (I'm a business course instructor). The ground work in preparation to present solutions, could involve doing research (heavy lifting) utilizing LLM. And perhaps the StudyFetch study results are precisely because student's are utilzing their own critical skills in their coursework rather than depending on LLM to do it for them- as most colleges discourage using AI for that critical thinking framework and can "smell out" the AI and fail the student. Consequently this explains why they students aren't utilizing the platform for offloading critical thinking tasks.
The college I work for encourages the use of AI for coursework- however there are other universities that discouarge it's use ( I know a IT instructor at a university that discourages the use of AI) so there needs to be a balance in how it is used as all trajectories indicate increased utilization in LLM in education as well as the other universes.
