Ms. Hagevik has, at the same time, been embarking on a project that has led to considerable revision of the way she carries out instruction in her classroom. Stimulated by various staff-development opportunities provided her in her school district, she has been trying to help her students develop important thinking skills and mental habits that will make her students better critical and creative thinkers. She has adopted an approach which she has observed other teachers embrace with great success – the infusion of instruction in skillful thinking into standard content instruction. And into this she has worked many of the techniques that I have referred to above. Ms. Hagevik’s concerns about what her students are learning about energy have now led her to think of this instructional context as one that is also ripe for restructuring in order to allow her to teach her students a number of additional thinking skills that she thinks will better prepare them for the challenges they will all face about energy as they get older – even if the challenge is one in the voting booth about who to vote for among candidates that have different views about energy in this country. And indeed, she thinks of this not as just about energy – these lessons will arm her students with skills that they can use in a tremendous number of other contexts that also will challenge them to so some good careful thinking.
