These are the class preparation sheets for my EDP 370: Applied Child Development Course: Unit 4 on Understanding Qualitative Differences in Thinking (Piaget). This prep sheet is associated with the Mouse Trap Car Activity. This course is taught as a 'hacked' course. Lectures are prerecorded for students to listen to at home, we complete activities in-class. The culminating project is the Children's Thinking Project (adapted from Penelope Oldfather & West, 1999). Thus, we integrated a series of interviews from American Public Media: Dick Gordon's The Story radio program into the pedagogy for students to develop their interviewing skills.
