This book was an interesting read. It really makes you think about both what you have been doing in your classroom as well as ways you can improve your teaching. I think it is important for students to have authorship in their own problem solving methods.
I do think that implementing this method would require a lot of work up front. If you teach the same topics every year, it is not the same level of work each school year. I do think that the level of work that has to be put in to implement this method could be a detractor for many teachers. It’s something that I definitely think should be implemented if you have a strong, collaborative PLC because you have both extra support and feedback.
