Just wanted to say that I totally agree with your third paragraph and (as an educator) have a suggestion - the current grade management tools like Canvas feel like they're about 10-15 years old. Making a better one that's open source would not only cut down on the ballooning administrative costs that are contributing to the problems with education right now, but could also contribute to making classes more hands on (by allowing the teacher to branch out beyond tests into more creative forms of assessment).
