Very few BS have a true modular schedule. I have heard that it involves a lot of work on the part of faculty to devise courses that are delivered this way.
But that also is consistent with all the pain everyone has felt as schools have made their way through covid. Teachers, often with next to no notice and definitely without additional professional development, have had to change everything from how delivered, frequency, etc. And while it’s been a TON of work for them, students have also felt the impact of getting material in itts maybe not quite ready for prime time format.
