1. The textbook or PDF is passive and student has to read. You can go back and forth, bookmark etc.
2. Khan academy is more videos and students listen. Tests are through quiz.
3. The new attempt is to make the students "do". Does it make sense to take the textbook content and make it interactive. This is especially true in the age of AI when we can create interactive snippets like @random_walker has done(https://x.com/random_walker/status/1848388462782673340)
Comparison where we map the textbook content to an interactive page(https://youtu.be/O39pIEHWOiY?si=0SbNVi7Vwlv4lme9)
What are some other learning methods which should be captured by future edtech startups? AR/VR?
