Thinking Through a Lesson Article Reflection

This article talks about Think Through a Lesson Protocol or TTLP. This is something that I have never heard of before and at first sounded kind of silly to me. The protocol seemed to be sort of common sense to me. I think that teachers should be naturally following the three stages of the TTLP without having to really think about it. The goal of teaching is to ensure that students are learning, and I think that this protocol does ensure that, but I do not see why a teacher would need to be told to do this. For example, in figure 2 the section of questions dealing with stage one include, "How will you group students?", "What errors might students make?", and "How will students record their work?". These are questions that teachers should always be asking themselves when planning lessons for any subject.
I think that the TTLP has a lot of great ideas in it, but I think that any good teacher would already be implementing those ideas even without ever even knowing what the TTLP is. I think that asking these questions and providing students with higher-order thinking problems is always a good idea and will benefit the students greatly. If the TTLP can help teachers to do this, I think it is a good idea.
