Excellent idea! And...you are completely correct in all you points! All government school classes should be videoed and streamed ON-LINE!
I was thinking differently, though. Why not video **one** teacher teaching the typical course work for 3rd grade arithemetic, or **one** teacher teaching fifth grade socialist studies, or **one** teacher teaching 11th grade American History?
Honestly,....It could be done **once** and would be good for 10 or more years. What's the BIG secret that this couldn't be placed on-line and be completely free to all the citizens of the state?
If this was coupled with certifiable and proctored exams, bright students could zoom ahead and graduate **YEARS** earlier. The slower students would have access to the on-line courses for review, and adult citizens could take enrichment courses or fill in gaps in their own educations and have a certification to present to an employer.
I bet this isn't done because it would mean the loss jobs for government teachers as bright students graduated years earlier. Personally, I believe we have government schools to provide **lots** of jobs for modestly talented white collar state employees. And....As you pointed out so well....The course content would be shocking.
Different problems. I was originally looking at a way to improve classroom discipline on the part of unruly students, and thought "hey....why not a vidcam in the classroom pointed at the students". If parents could monitor the behaviour of their precious offspring (and their misbehaviour) themselves, I thought that discipline problems would quickly diminish. I then realized that a second camera, pointed at the "teacher's station" would also address the "teacher incompetence/brainwashing" issue.
I think the ultimate endpoint will be some combination of both our suggested approaches. One thing you don't mention that I see as happening is that there will be more than one approach to teaching specific subjects. Some students just learn differently than others. The vid-course approach allows the development of multiple teaching/learning styles beneficial to the different student "learning types".
The BIG secret is that it makes BIG money for the re-publishers of this [mostly trivial] material.
