Reading about all the struggles you've had, the much spent time, and the fact that you "want to find an approach that will work for other teachers, other classrooms, other students", it would be great if you could try out a spaced repetition system that's been created specifically for school/classroom use and let me know what you think. The site is https://ankimono.com/school . It's not as feature intensive as Anki, and was created more for the non-tech-savvy. You can reach me via the support email address of the site (I'm the owner).
