During our novel unit, I took a handful of traditional paper assignments and posted them online. When lab availability allowed, I took the entire class and required that the assignment be submitted electronically. For the other assignments, I accepted paper copies but found that most students with Internet access in their home preferred to turn them in online. I also found that I had the same - or higher - assignment completion rates with the online assignments.
I also realized that I was more likely to write comments on the online assignments because it was much faster to type a quick comment. The students responded very favorly to my comments - which were delivered to their message stream - and many then chose to respond back thanking me for the kind words.
Once the grades were entered, it did prove more difficult to get them into my actual Skyward gradebook. The file can be downloaded as a CSV, but I found it easier to just print out the page with the scores and reenter the grades rather than fighting the technology.
