One of the goals of 21st-century teaching and learning is to share the role of teaching with students. The document camera is a very useful tool that helps students become the teacher. Sharing student work gives students a chance to offer feedback to each other, which helps to foster another important 21st-century learning skill: collaboration!
Our math periods usually follow the format of:
The teacher poses some sort of a problem for the class to work on.
Working On It
Students work in various configurations (partners, independently, small group with the teacher) to find a solution or multiple solutions to the problem. Students use various tools to record their strategies and communicate their thinking. This is often done with models of math manipulatives and sketches/notes made with pencil and paper. When the iPads are in play, it might include photos and audio explanations OR videos. Often the teacher documents student learning for assessment with photographs and notes as well.
Reflect And Connect + Explicit Teaching
The group reconvenes to share their solutions. Here, students take on the role of presenters and teachers, sticking their models or written work under the document camera and projecting them up for the class to see as they share their thinking. When iPads are available, students may connect the iPad into the LCD projector so that all can view their work on the "big screen."
The teacher continues to act as a facilitator to help guide students towards their mathematical understandings.
