q2 · i? · design · r2

Case study 1: the authors' structured rapid review of the I Can Read early childhood literacy product against the five Science of Reading Big Ideas, using weight-of-evidence ratings by two independent researchers. The review found high alignment for phonemic awareness, phonics instruction, fluency and comprehension, and low alignment for vocabulary. No effect sizes are reported.

"While the degree of alignment between four of the big Ideas of Science of Reading and I Can Read materials was high, it was low for one of the Big Ideas, Vocabulary."

q2 · i? · design · r2

In the same case study, after the misalignment finding was shared with the I Can Read team, the company revised activities and designed new ones for vocabulary alignment. The authors interpret this as showing that the iterative theory-of-change process "can result in significant improvements to educational materials". No outcome data are reported.

"they engaged in a significant effort to ensure that the revision of existing activities and the design of new activities were in alignment with the research on effective vocabulary instruction"
