At every school <strong>the</strong> CPS approach was compared to‘‘traditional’’ problem solving practices that emphasize equations <strong>and</strong>ma<strong>the</strong>matical procedures. At School A this comparison was madebetween a single teacher’s classes over multiple years, at School B <strong>the</strong>rewere multiple classes taught by <strong>the</strong> same teacher, <strong>and</strong> at School C <strong>the</strong>rewere two different teachers (a CPS teacher <strong>and</strong> a control teacher). Toensure flexibility, only non-Advanced Placement physics courses wereused in this study.There were differences in <strong>the</strong> teachers’ knowledge <strong>of</strong> physics <strong>and</strong> <strong>the</strong>irteaching experience. The student populations at each school varied aswell. For example, School A was a small suburban high school with an
