It might be worthwhile to distinguish between lesson content and the student experience.
For instance, if a million students watch the same video lecture on mitosis, have all of them had the same experience? Of course not. Different students have had different backgrounds. Some understand particular analogies that the lecturer makes better than others do. Some are colorblind and have more difficulty understanding a particular animation that is used.
And then there is the context in which that lecture is presented —
Ten of those million students are watching the lecture in a seminar classroom; and when one student gets confused, they pause the video and discuss it. Another ten students are watching the lecture in a different classroom; and when one student gets confused and looks out the window, he or she is punished for being inattentive.
Some students are watching at home on their laptops, and pausing the video to look things up on Wikipedia. Some are listening to the lecture as they drive to work or mow the lawn.
Five other students don't watch the lecture at all. They agree to read the Wikipedia article on mitosis and whichever linked articles or sources they think might be interesting. Then they meet at a coffee shop and discuss it.
True, but I don't see how that relates to the central point. Do you think that individual differences are large enough such that the gains to be made from specialization aren't large enough to justify the investment I'm proposing?
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
