So far I've tried building my presentation from elements, each of which is differently paced.
A lot of tutorials are given just by rapidly writing fully worked solutions on the board, thereby leaving little room for actual discussion of concepts. I don't like that kind of tutorial.
The last tutorials I taught were based on the fact that the maths school would release fully worked solutions electronically at the end of the week and encouraged their tutors to have a more "lesson" based presentation.
I ended up with a presentation based on putting skeleton solutions comprising a list of sub questions that just referred to the appropriate concepts from the lectures. Then I asked the class to come up with the answer to each sub question so that they could see how a solution was built up and could contribute to its construction.
Then of course, even though you are keeping the ones who want to move faster happy by giving them the opportunity to participate and thus not get bored, you still have to regulate who's answering and how often and how to encourage the weaker students to have a go.
Any thoughts from others on how they handle this are welcome.
