概要	Visual elicitation multiple case study is a qualitative design that embeds photo or image elicitation techniques within a multiple case study framework. Photographs, drawings, or other visual artefacts — produced by participants or the researcher — serve as interview stimuli, enriching within-case depth and enabling rigorous cross-case comparison. The approach leverages the power of images to surface tacit knowledge, making it especially valuable for researching contexts, identities, or experiences that are difficult to articulate in words alone.	Multiple-case study design investigates two or more bounded real-world cases using the same research protocol, then compares findings across cases to identify patterns, contrasts, and explanatory insights that a single case could not produce. Developed primarily through Robert Yin's replication logic and Robert Stake's collective case tradition, the approach is particularly powerful when a researcher needs to determine whether a phenomenon occurs under varied conditions or to test an emerging theoretical explanation against rival contexts.
