Step 1: Identify assumptions about change.

Through interviewing the Math World advocates at the district, reviewing the intervention itself, and reviewing research literature, you identify the underlying assumption about change. The assumption is that students who are given frequent opportunities to solve complex, open-ended math problems rooted in concepts they are learning will exhibit two effects:

• Effect A: increase their understanding of important content in the math curriculum.


• Effect B: improve their general skills at solving complex math problems and communicating well-reasoned, evidence-based solutions.

The evaluation goal is to see if the effects are achieved in the district.
