Our guest for this episode is Saro Mohammed, Partner at the Learning Accelerator. The Learning Accelerator, or TLA, works directly with school districts and states to develop implementation strategies for blended learning, doing so with a focus on conducting and disseminating rigorous research to support their work. Saro talks with us about efforts to measure blended learning to determine if, when, and how blended learning is effective in achieving its goals, and shares some insights on how that measurement takes place.
