The initial pretest will be in the form of the game Balderdash. I have created cards with ethical theories, ethicists, and other common ethics vocabulary words. I have also written the correct definition on cards. Each student will create their own definition on a card. They should write the real definition if they know it. The students will use clickers to vote on the correct definition.
I ended up using a simple multiple choice test using clickers. Balderdash might have been fun but too distracting.
