Evidence¶

Clinton 2015¶

Clinton, V. & Cooper, J.L. (2015, April). Teacher Viewpoints of Instructional Design Principles for Visuals in a Middle School Math Curriculum. Paper presented at the Annual Meeting of the American Educational Research Association Annual Meeting, Chicago, IL. https://eric.ed.gov/?id=ED574965

q2 · i? · causal · r1

Open-ended survey question coded into yes, maybe/depends, and no categories for control and treatment teachers. The article prints χ2(2, N = 38) = 10.47, p < .01 and the cited percentages; no effect size reported.

"the distribution of teacher responses across categories differed for control and treatment teachers, χ2(2, N = 38) = 10.47, p < .01). Among the treatment teachers, 45% expressed both pros and cons of visuals in their responses (compared to only 17% of control teachers)"

Related Claims¶

• Both control and treatment teachers believed labeling benefits learning, disagreed that color coding made lessons too easy, and believed pictures help ELL students — related
• Treatment teachers generally liked the revisions to CMP2 visuals, especially increased color coding and labeling, and liked the revisions at least as much as control teachers liked the originals — related
• Treatment teachers viewed math-irrelevant visuals less favorably than control teachers, suggesting use of the revised curriculum and PD shifted views — related
