Try a jigsaw approach.
No, we’re not talking about puzzles or scary movies. If you’re introducing new, difficult content, divide the class into groups and ask each group to master only one portion of it at a time. If, for example, you’re teaching the American Revolution, have one group focus on the Continental Congress, one on Washington’s Army, one on French support for the war, and so on.
Ask them to do a reading on their topic – to become the class “experts” on that subject. Then split up the class into new groups that include one “expert” on each topic. Ask these new groups to work together to write an essay or complete a worksheet that requires information about all the topics. They will teach each other in the process.
