I agree with your larger point that the traditional lecture style education is not good for everyone.
You may have suffered through traditional "higher education," but a new generation is learning a different way. Some of them are learning it better. We have made tremendous progress in many fields, why do we not study the process of academic instruction just as intensely as, say, nuclear physics?
We do. Some physics department, like the one from which I got my PhD, offers research in physics education as a PhD program. Student do research and gather data in classroom and apply the same statistical analysis techniques to asset the effectiveness of certain teaching techniques. Unfortunately, they usually do not get the same respect in the department as more traditional thesis topics. Usually there are a few (<5) faculties out of the whole department who actually care about physics education that they accept student in these topics. The APS is starting to recognize it as a specialty, but only treats it as a "special topic". We are getting there.
Khan Academy is good, a lot of people use those videos!

When I was TA-ing to pay my way through my degree, I recommend KA to many intro physics students. Then after talking to a lot of them, I find the result to be kind of mixed. Some find it helpful, other not and it somewhat surprised me that it did not correlated with grade. The worst case is that some thinks it's helpful when in fact it did not (and you can tell by asking conceptual questions that is only a twist of the problems covered in the video). Totally anecdotal. However, fellow students who actually engaged in physics educations research tents to agree that a one way dictation, abet using video, do not help student who lacks a good conceptual foundation to begin with. And this guy, who also did a PhD in physics education, also agree. I do think the world is better with those video than without though.
