摘要	Evaluation-focused concurrent embedded mixed methods is a research design in which both quantitative and qualitative data are collected simultaneously within a program evaluation context, with one strand nested inside and playing a supporting role to the dominant strand. The design produces outcome evidence alongside embedded process or contextual evidence from the same evaluation cycle, without extending the timeline.	An embedded case study is a case study design in which one or more units of analysis are nested within a single overarching case. Rather than treating the case as a single, holistic entity, the researcher deliberately examines multiple sub-units — such as departments within an organisation, classrooms within a school, or programmes within a hospital — to build a richer, more nuanced understanding of the phenomenon under study. Formalised by Robert K. Yin, the design is contrasted with the holistic single-case study and with multi-case (multiple-case) designs.	Program evaluation is a systematic, empirically grounded process of collecting and analyzing information about a program to determine its merit, worth, or significance. Applied across education, public health, social services, and policy, it addresses questions such as whether a program is reaching its target population, whether it is being implemented as designed, and whether it is producing the intended outcomes. It draws on both quantitative and qualitative methods and serves accountability, improvement, or knowledge-generation purposes.
