I am always curious regarding new education solutions. I firmly believe the US pre-college education systems are fundamentally broken most benefit from edtech (huge fan of Khan Academy).
As an MIT alum myself ('89), I am surprised to hear your description of your experience at MIT. Did you experience this across all classes and departments or only for a few (e.g. 18.01 which is required for most freshman)? While certain professors were not the most helpful, I found most of the teaching staff to be incredibly helpful when I made the effort to engage them. No doubt the focus was on attendance in lectures.
In addition to lectures there were:
- Recitations - each class of the larger classes had recitations with a TA to allow smaller groups the opportunity to ask specific questions.
- Office hours with the lecturer. I did not avail myself of them as I considered them useful for bigger questions (should I be a physics major if I don't understand this) rather then review of homework questions.
- Bibles. Each living group (I was in a fraternity but dorms had them as well) had a library of class notes, exams, quizzes, etc for each class assembled by people who previously took the class and did well. Often the Bible author was still available for questions.
- Friends/Fellow Students. MIT has an incredibly open policy on working together. My recollection is some classes could not be reasonably completed by people working alone (e.g. Aero/Astro's Unified Engineering). A fellow student may simply have looked at a topic from a different perspective which drove their comprehension.
Today, MIT offers OpenCourseWare (ocw.mit.edu) which hosts complete courses online (video, lecture notes, syllabi, additional readings, quizzes). This is an incredible resource that I have found helps my lifetime learning goals.
Again, I am always excited for edtech. I think its development needs to be tempered with an understanding of why current systems are not working. What problem are you solving? Is your solution simply remote tutoring? If so, how is it different that a job board with zoom?
