So, we're working on a study for online Vs in person.

We've noticed that stiict time limits alone tend to shift grades. A locked down browser sounds great, but anyone can search using their phone, so proctoring is a must (but also time consuming to check) if you want to get the intended effect.

As for online grading, it's a mixed bag. With a very strict rubric, gradescope can save a lot of time, but otherwise it takes a lot longer. MCQs and single number answers can be auto-matked, but they're awful at assessing ability and should be avoided. Overall, grading online costs more than it saves, and tends to give much more rigid feedback to students.
