I noticed in my class that my students were not "thinking about their reading" while they were reading. I would model this to them, by stopping and thinking while I read (aloud). I would also stop them from reading and ask them questions. However, they were not doing this on their own. Now I use this metacognition worksheet in my classroom and I have the students stop after each page or when they notice themselves having a "thought" and write it down, along with the page number of the book. The kids actually really enjoyed it because they could tell what they were thinking, feeling, or ask questions they had (explaining their curiosities or predictions). I have really noticed my students metacognition increasing this year, and I later did not have to use this worksheet, but instead had them write their thoughts next to our reading passages, etc.
