All good examples but all relatively low cost as well (and don’t require 1:1 student-laptops). However I’m pretty darn sure that videos do more harm than good - too easy to zone out during them, and providing them to students only allows them to slack in class with the attitude “I can just watch the video again later.” Despite being horribly inefficient this is true for students of virtually all ages. Providing videos to those who ask only might help.

The real problem beyond all this is that the educational spending goes to the wrong spots. If you ask me, teachers should be empowered to select their own curriculum using a budget and most of the rest of the money should go towards paid tutors, better teacher-student ratios, etc (and probably way fewer administrators). I am firmly convinced that a lot of kids act out because they can’t grasp the material, not in spite of it.
