I agree with most of what Willingham expresses in this chapter. I just wonder about the feasibility of it all. At the end, he suggests reviewing everything in your lesson plan to avoid students thinking about unintentional topics.
WHO HAS TIME FOR THAT?! Seriously, many teachers I know barely have time just to get their lesson plans ready for the next day, usually due to the requirements administrators put on them with what needs to be included (i.e. SOL strands, Essential Questions, Short-Term & Long-Term Goals) Not saying that all of those things are not important, but teachers become more worried about the formatting of their lesson plans rather than the content and execution of their lesson plans. Now Willingham wants us to analyze it even more?
I would like to see this in action personally. I wish he could send me a video of a teacher who does this and I would like to also view their process of getting there.
