A tutorial is not a small lecture. Four short lessons on facilitating real discussion and learning in small groups, then a self-check.
The instinct to rescue a quiet room with more talking is the main thing that kills tutorial learning. Get comfortable with the pause.
Discussion rarely happens by accident. Plan the questions and the shape, and give students something concrete to engage with.
Simple structures spread the work and the thinking across the whole room, not just the confident few.
A good tutorial hears from everyone, not just the usual voices. Design participation in rather than hoping for it.
