The idea was that the school staff would break into grade-level groups with an expert assigned to each. The group would advance to the next third-grade classroom and observe a second teaching session. Each novice teacher got to observe several teachings of the same lesson with several different classrooms of children, including their own children. The experience was followed by a processing session at the end of the day, and a plan for the next phase in which the novices team up and team teach in each others classrooms. Again, release time is required, but only an hour at a time.
Substitutes can rove while teachers work together to gain skill and confidence.
In very short order the novices are teaching hands-on science on their own. The second model is the one-week summer camp model. Teachers convene at a year-round school that has agreed to offer up several classrooms for a couple of hours a day. The teachers split their time about equally between group instruction in philosophy and pedagogies, lesson preparation, and teaching in classrooms with students. Every day the team of three or four teachers planned the activities and shared the instruction.
