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.
The students' Digital Content Notebook is where Pencil and Paper Notetaking occurs. It is exactly what it sounds like. No frills. But it is even more essential in a blended format. My colleagues and I did a lot of note-taking style modeling at the beginning of our year to set the expectations in our blended classroom.
Opening Bell is a strategy I use to start class every day. I start by asking students to "clamshell" their computers--closing their devices almost all the way--and then I give a whole-class greeting. We spend the next two minutes checking the review section of the class agenda and preparing for the whole-class mini-lesson, announcements, and/or administrative tasks. Given that my students spend a significant portion of each class working independently or in small groups, Opening Bell gives us the opportunity to come together as a whole-class community before students start working on their own.
I use this strategy to activate my students' interest and prior knowledge on a topic. This gives me a good starting point on the curated video and reading list for the independent station. It also gives my students a visual representation of the range of interests in the class. In my opinion, using the interests of my students to guide instruction is the core of a student-centered classroom.
