  1. Algebra I 25.1 Students use properties of numbers to construct simple, valid arguments (direct and indirect) for, or formulate counter-examples to claimed assertions.

  2. Item Testing 25.1

  3. Reframing Science Science is always conjectural. We can’t prove anything. Yet, research can give us we warrants for proceeding on the basis of our conjectures.

  4. Features of Research • Systematic • Rigorous • Iterative

  5. Strengths • Practicality • Flexibility • Community-building • Locally meaningful • Successful change agent

  6. Obstacles • Lack of support/time • Test Data Culture • Unclear goals • Difficulty formulating questions • Data interpretation • Too many interventions
