I'm also enthusiastic about new education solutions, and I found traditional MOOCs are 1. too long for one sit; 2. passive; 3. lack personalization. So I'm building a new solution that aims at solving these problems: https://afaik.io/ https://afaik.io/, and you can learn college physics and calculus for free. The goal is to map out the prerequisite structures among all subjects as knowledge is actually a continuous map, and let everyone have their own personalized learning path. It's visualized like this: https://afaik.io/nebula?category=brickset&id=VLlOnZLl&mode=dagre https://afaik.io/nebula?category=brickset&id=VLlOnZLl&mode=d.... The learning unit (called brick, like Lego brick) is designed to be 10 minutes, questions are asked at the end to check understanding. Don't get me wrong; I love OCW and I think it's still one of the best free resources online. But I do think great resources combined with AI can bring such innovative edtech solutions that everyone can have their own private tutor almost for free, and most importantly, without worrying about hallucination effects.
