概要	Evaluation-focused case-focused mixed methods integrates an explicit program evaluation framework with in-depth case study inquiry, combining qualitative and quantitative data within a bounded unit — a program, site, or organization — to render both descriptive understanding and evaluative judgments about merit, worth, or significance. The design serves applied evaluation contexts where holistic case understanding is needed alongside evidence-based performance conclusions.	Multilevel mixed methods design is a research approach that collects and integrates both quantitative and qualitative data at two or more distinct levels of a social or organizational hierarchy — for example, individuals nested within classrooms, classrooms within schools, or patients within healthcare teams. By pairing quantitative measurement of outcomes at one level with qualitative exploration of meaning at another, researchers gain a richer, more complete picture than either strand alone could provide.
