The grouping algorithm employed by School of One assigns students a new lesson every day based on the student's most current learning needs. The algorithm actually learns the students' needs from the previous day's exit ticket. One of the learning styles or lesson types, Live Investigation, assigns students to me who are ready for whatever the assigned skill is. However, within that group, there are still varying levels of ability. I can see all of this on my data report and then I can group within my group. I call this micro-grouping.
Formal transitions happen twice during a double-block period. My students have to move from one section of my extra-large classroom (3 classrooms merged into one) and move to another section for a new lesson with a new teacher. My students have two minutes to transition from session to session, and we play a variety of interesting music on the surround sound stereo system to keep it fun.
My colleagues and I have students write a Synopsis of their learning after every Independent Learning Zone period as well as after Live Investigations. The Synopsis acts as a reflective tool for both large and small concepts. I often tell my students to write what they actually learned or improved upon, not what they THINK I want them to write. I train my students to make a space for the Synopsis in their notebook headings. Occasionally, I will have my students read their Synopses out loud, but most often I walk around and do a quick check, as they are mostly a personal reflection for my students.
I use the Closing Bell strategy to bring my students back together as a community at the end of each class to check for understanding, debrief the class, give "grows and glows," and/or preview what we will be doing the following day. Building in this type of closing at the end of class is especially important in a blended classroom when students are spending so much time working independently or in groups.
