I've been teaching/tutoring people on how to program since my high school days. One of the best tools I've come to rely on is being able to show my student what the end result of the program looks like and how it behaves. Its often much harder for people to realize what you are trying to do with specific lines of code without having seen what the end goal is. Having seen the final result and working backwards along side you to figure out the bits and pieces that would be required to make the end result work is something far easier and more natural for people based on my experience.
#4 sounds like an awesome idea. who's with me? finding the right balance between how much people are willing to pay based on the quality of the teachers and making it worth while for quality teachers to spend their time would be a challenge I'd imagine among other things but I really do like the premise.
i think the difference here is between the two different experiments (one with three rolls of the dice and one with a single roll) and not a difference between the groups. You could choose to use the exact same group of participants for both experiments.
Something interesting I think the article did not mention is that given the difference between the two sets of experiments, where you roll once vs you roll 3 times.
As a participant I'd feel more inclined to lie about my first roll if I rolled a higher number in my second or third attempt.
I'd be very interested in the results if n was not 76 but instead 7600.
