There are now some computer programs to help you create crossword puzzles. Videos Videos offer an alternative presentation mode for course material. Screen them to make sure they are worth showing. These can be formal or informal, individual or group, and graded or ungraded. They allow students the opportunity to take a thesis or position and gather data and logical arguments to support that view, critically.
Debates also give students experience with verbal presentations.
Some faculty members ask students their personal views on an issue and then make them argue the opposite position. This can be used for review or for the actual exam. This technique helps students actively process material, gives them a better understanding of the difficulties of writing reliable and valid exam questions, helps them review material, and gives them practice for the exam. Either way, have students present their research in a class research symposium similar to what we do at professional meetings. Invite other faculty members and students.
