I generally let the students initiate the topic,but all fast talk has to relate to what we have learned that day or prior. Sometimes if everyone is being shy then I may throw out a Key Word and let them role from there.
It is really fun to hear what they have honed into, we think the points we find fastenating are what they are likely to mention, most times nope, they have their own ideas.
This really encourages participation and even the quiet person has their moment to shine.
