have them write about it first. then have them explain what they wrote… once the students has their thoughts on paper, i think they approach them as more valid and real than when they are just floating around in their heads.
so i guess, write 3 paragraphs and 3 questions, the three paragraphs on something they ‘found’, ‘thought’ etc. and 3 questions that they think they can talk about.
and the nice thing is that this excercise gives you some understanding of their reading/analysis skills.
