概要	Design-based intervention mixed methods is a research design that embeds both quantitative and qualitative data collection within iterative intervention cycles drawn from design-based research (DBR). The approach systematically tests and refines a practical intervention — typically an educational program, curriculum, or organizational solution — while using qualitative data to explain why and how the intervention works, and quantitative data to assess its measurable impact. Iteration between design, testing, and revision is the hallmark of this approach.	Intervention mixed methods design embeds qualitative data collection within an experimental or quasi-experimental study so that process, mechanism, and participant experience are captured alongside outcome measurement. The quantitative strand tests whether the intervention works; the qualitative strand explains how and why it works — or does not. The two strands may be sequenced before, during, or after the intervention phase, or run concurrently, depending on the research questions.
