We had previously determined the lesson that we would use the concept mastery routine with. We planned to observe the lesson on the day the concept mastery routine would be taught. Since we chose to work with a co-teaching team, we decided that we would observe different blocks so that the students would not be distracted by both of us being in the classroom. Britt observed the first block and then we met with the teachers to talk about what went well and what challenges existed. We made suggestions and then I observed the next block. During the first block, students were hesitant to participate so we suggested that they ask more leading questions. This prompted the students and they become more engaged during the next block. This process worked well and the team was appreciative of the opportunity to learn how to use the routine.
