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.
During an Independent Learning Zone session, every student in my blended classroom is working independently on a different set of problems. It's impossible for me to be an answer key for 25 different students doing 25 different problem sets, so I print out their respective answer keys in advance and give each student his or her about 5-10 minutes into the period. This empowers them to monitor their own academic performance and self-correct as they are completing their assigned task.
Assessment and data play a crucial role in a blended teacher’s classroom. Blended learning gives teachers an opportunity to assess consistently throughout a class, in a way that drives instruction, impacts grouping, and assignments. Blended educators have to develop capacity to sift through multiple sources of data and synthesizes quickly into action. Check out how Aaron utilizes Assessment and Data here.
The core ideas of my classroom are big ideas and themes that run through almost every lesson I teach. They are good math values, work values, life values. Whenever they come up during a lesson, I always explicitly make the connection. Next year, I plan on using a graphic for each value (some kind of eye graphic for core idea #1) to show, in my lessons, where the ideas come up.
