Whole Group Discussion
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.
My students respond well to kinesthetics. Popping up for an answer choice or when they are ready to move on to the next topic is a way to keep the students engaged and also check for understanding. Turn and talk - students turn to talk to their neighbor about a question/problem/scenario that was posed. One of the partners then reports out by either being chosen from the equity sticks or by volunteering by putting their thumb up. I use Shoulder Partner strategy to give students the opportunity to talk, share and explain content to each other. This strategy is good to increase the accountable talk in classrooms and to practice speaking and listening skills.
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.
I noticed that students both needed and wanted a quick and engaging introduction to content. Instead of simply asking what do you know about this topic students prior knowledge is activated through a often funny yet very informative video segment on a topic. These videos are great for introduciing Social Studies content because they take often large and abstract topics and make them accessible for students.
