Overall, I think my students liked the Concept Mastery Routine because it allowed them to revisit and review the topic of intellectual disability that I had been covering for most of a three hour class that night. I think the most beneficial piece for them was distinguishing the always present characteristics and the never present characteristics as this really solidified their understanding of what defines an intellectual disability. A challenge in regards to the concept diagram was co-constructing the key words list to be used in the diagram. I always find that I want to just provide this piece, but it is more effective when the students are generating their own list with me. Something I might do differently the next time I use this with a class is have them break into groups and come up with some ideas for the key words, then brainstorm as a class the ideas they generated in their groups.
