EdTech tools need to be based on research and incubated in a few partner school.s I’d add that they also need to attack the biggest obstacle to change in schools - PD. Teachers adopt new products and pedagogies at different paces. The products with the largest user bases are the ones that need little or no training. At the same time, these tools tend to be very tactical and incrementally improve the learning experience. What is needed is an adaptive UI/UX for teachers. The same code base should be able support teachers with a broad range of experience using the tool.
