Bests & Worsts Reviews from Amazon

At $26, I'd hoped to learn more about how to put into practice the Right Question technique but I found the book didn't offer much more than the article the authors wrote in the Harvard Education Letter. Although they make clear the NEED for students to formulate their own questions, the classroom logistics are less clear. It would be helpful to have a blog created around the book/article for teachers with practical questions. For example, if students don't know much about a subject, their questions will be off-topic or shallow. How does a teacher front-load the requisite knowledge without losing student engagement? I have as many questions today as I did before I read the book.
