In terms of what has measurable effects in the classroom there is a very rigorous study by Hattie: "A synthesis of over 800 meta analyses relating to achievement" In it, things like computer assisted learning, simulation and games, testing etc have a very low effect. Primary is things like feedback and other things that come down to the teacher. A partial list is contained here: https://www.det.nsw.edu.au/proflearn/docs/pdf/qt_hattie.pdf https://www.det.nsw.edu.au/proflearn/docs/pdf/qt_hattie.pdf That said, a big theme for what works seems to be personalization, custom feedback, custom progress, and computers should be great for this. It'll still be hard to beat a great teacher: in grade 1 alone there are close to 20 different reading levels that each student needs to be supervised through on their own pace
