    A good example of how science always questions itself is the problem of aether. Some scientists in the 19th century believed that the universe has a layer of common substance that permeates it. Some did not. Experiments were done, and the latter view won.

    "Apparently you haven't been subjected to enough PowerPoint presentations to believe just how pointless presentations are. "

    Whatever documentary I have seen on TV, it stays in mind. I've learned quite a few theorems in this way from a BBC educational program. It was far easier than reading.

    "The home work a student does aren't usually for general consumption"

    Don't they say that you haven't really comprehend something until you are required to teach it? I fully agree with that. Forcing the students to present their knowledge in a form which requires coherence would make them understand the material they deal with.

    "as a visual analogy for a concept is presented rather than presenting the concept in straight language"

    There is no difference from reading. Reading, at its worst, is an audio analogy, and at its best, is as visual as a presentation, if you care to exercise imagination.

    "And compared to reading speeds visual presentation can be very slow.Wikipedia would not be improved if it were converted to a narrated visual media."

    I think it would. For every concept I have searched Wikipedia for, a visual representation would convey the information much faster. For example, by the time I have to read the concept of particle duality in quantum physics, I nice animation would have presented that and the double slit experiment as well.

    "Of course actually doing it tends to be better. And static presentations on paper may be a better bridge to the 'power tools' of physics: formula and mathematical manipulation. The ability to deal with the abstract rather than the specific and translate back and forth is the hallmark of many scientific disciplines. Visual presentation probably wouldn't help as much as one would hope."

    Why not play with the mathematical formulas on the screen and also watch an experiment derived from the formula? for example, I could learn relativity much easier if I can play with a formula (say, gravity) and also watch the effects of it on a planet, object, star etc. Only an electronic medium offers such a possibility.

    "Unfortunately working how to use them right is not straightforward. I don't mean to be dismissive, but I suspect many quite bright people have been working on this one and given the observed results, it probably isn't an easy problem."

    I think it is very easy. The wrong thing people usually do is transfer the narrative property of a book to the screen. That's wrong. What is right is to show a few things on the screen, and let the child experiment with it.

    For example, in a history book, don't show a list of chapters to a child, but a timeline where he/she can choose to see the main events on it. He can then click on an event and see another timeline, more detailed, concerning the specific period, and select any major event to play with. After clicking an event (say, a historical battle, for example, Waterloo), he can then inspect the landscape, the tactical play of the two armies etc, and then even proceed to play with it by changing the parameters and watch a different outcome.

    Is it really true that there are gifted and non-gifted people when it comes to school? from my personal experience at school, and from watching my sister's kids and their interactions, I can't say that children that do not do well in school are not gifted. They are simply not approached in a way that allows them to shift their interest to the subjects at school.

    I find it extremely interesting that I have a really hard time to feel at home with "lower class" people. I am educated, I have an MSc in software engineering, my interests beyond computers are astronomy, physics, sci-fi, soccer and basketball, and I find it extremely easy to communicate with people in the same status as me or in higher status. But I find it extremely hard to participate in discussions carried out by people with lower education than me, like workers, plumbers, etc. But it is not that their discussion is stupid, actually it is extremely intelligent, with subtle cues for almost everything, which I have a hard time understanding in time so as that I can participate as an equal in their discussion.

    So, who is really cleverer? I don't consider myself cleverer than them. I am not more gifted, although I was amongst the top-rated students at school and they were average or below average.

    Watching a 10 minute documentary about a historical event is a much more interesting way to teach than have people read a white paper with black letters, for example.

    How about watching animated physics presentations on the big screen instead of static presentations on paper?

    Religion was not misused to exploit ignorance. Religion *is* ignorance. Even if religious leaders don't exploit believers, these people tend to take things as they are because 'God made it so'.
