Tóm tắt	Visual elicitation case study is a qualitative design that embeds photo or image elicitation within a case study framework. Participants respond to photographs, drawings, or other visual materials during in-depth interviews, generating richer and often unexpected data than verbal questioning alone. The case study structure then situates these image-prompted accounts within a bounded real-world context — an individual, organization, community, or event — enabling a holistic, detailed understanding of the case.	Case study research is a qualitative research design that investigates a specific phenomenon, individual, group, organisation, or event in depth within its real-world context. Systematised by Robert K. Yin in 1984, it supports single-case and multiple-case designs and draws on multiple data sources — interviews, observation, documents, and artefacts — to build a rich, contextualised account of a bounded unit.
