Evidence¶

Paul Macaruso 2020¶

Paul Macaruso, Shani Wilkes, Jen Elise Prescott. (2020). An investigation of blended learning to support reading instruction in elementary schools. Education Tech Research Dev. https://doi.org/10.1007/s11423-020-09785-2

q2 · i? · causal · r2

Descriptive comparison of mean RIT score gains for the treatment school with the highest free/reduced-price lunch percentage against the whole treatment group's gain. The article reports both gain figures as printed; no inferential test accompanies this comparison.

"One of the treatment schools in this study served a large percentage of students (80%) who received free/reduced price lunch. Students in this school gained 13.70 points in terms of mean RIT scores, which is nearly identical to the mean RIT score gain (13.61) for the whole treatment group."

Discussion¶

Learner Variables¶

• Socioeconomic Status — moderator: an instructional effect differs by group
