Assign students to heterogeneous groups. Check to see that student work is completed before allowing groups to begin. Provide a separate space for students who have not completed the assignment to complete the work before they join their assigned group. Ask students to listen in their groups while members take turns sharing terms that they selected to highlight. They begin by clarifying vocabulary, using each other's thinking and whatever reference materials are available to them in the room.
Groups move onto the next step at their own pace.
Once all students have had a chance to share, prompt the groups to reach a consensus about which things are the essential key points. They can take notes by underlining things that others selected that are different from their own. Each student constructs one abstract. Ask students to listen in their groups while members take turns sharing their abstracts. They can take notes on things that are different from their own.
