I'm interested in these factors, as well. For instance, do students drop-out of online courses, because they aren't learning as much from them when compared to equivocal traditional programs? Or does students' perceptions/notions of online learning result in them thinking it's just "not as serious" as in-person instruction, resulting in greater drop-out numbers? I recall seeing a lot of students on social media recently saying that they felt the online classes they were taking during COVID should be offered at a "discount" compared to the traditional courses, because "online classes aren't as serious," even when they covered the same content and were taught by the same instructor. This perception that students have of online learning as "not being as good/serious/high quality as in-person instruction" might result in greater drop-out rates, regardless whether or not the research actually supports these notions. Similarly, I wonder if it is possible if some students may simply just not have as much experience (or confidence) with learning via online instruction. We often assume that students who are competent at communicating online (like via social media) are therefore equally as competent at learning online in a more high stakes or "formal" setting. However, this may not be true, and students (as well as their teachers) may need to "practice" online learning before they become competent at it. In a personal example, I work for a high school district that had a difficult time reaching students when the pandemic first started and we were made to teach completely online. However, over time, as both our teachers and students became more comfortable with the process, we started seeing our students becoming increasingly receptive to online learning, and some have even gone from openly disliking it to expressing a preference for it (over the course of a year). I am hence curious to see the effect that the pandemic and the associated "year of online instruction for all" will have on this and future generations of students in relation to their receptiveness to online education (and to see if this will ultimately affect the drop-out rates associated with online instruction).
