Positioning is a strategy I use, especially at the beginning of the school year, to ensure that my students know where they should go, what they will do at each station, and how much time they will spend at each station. Positioning occurs after I welcome the class (please see the "Opening Bell" strategy video) and before they begin rotating. I typically project the group assignment page from our class website onto the smart board and do a few quick checks for understanding before I let students go to their stations.
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.
Like It-Love It-Gotta Have It is a strategy I use to differentiate assignments within my micro-groups in a Live Investigation. The three names are, in my opinion, a better way of saying high, medium and low. The kids really love the names. In a Live Investigation, there is usually varying levels of abillity or knowledge in that particular skill. By making a high, medium, and low activity, students have the ability to challenge themselves at their own level. I assign different parts of the room for each activity so I can physically see where the students are. Most of the time, I let the students self-assess and they move throughout the room according to which level they are. They are free to move (up or down) from one section to the next. Most of the activites I assign here are digital. I really like using Khan Academy here, as I can track students physically as well as digitally. With this strategy, I can also target the students at the Like It level and allow the Gotta Have it students to fly a bit on their own.
During Live Investigation and Task sessions (both teacher-led), I often use a whole group discussion format just like a traditional classroom. Blended or not, there is no substitute for discussion.
