Podsumowanie	Action research is a collaborative research methodology in which researchers work with practitioners and community members to investigate a problem, implement change, and evaluate outcomes, cycling through reflection, action, and learning. Developed by Kurt Lewin (1946), action research bridges research and practice, aiming simultaneously to produce knowledge and practical improvement.	Case study research is an intensive, contextual investigation of a single case (or small number of cases) to explore a phenomenon in depth. Developed systematically by Robert K. Yin (1984) and Robert E. Stake (1995), case study research employs multiple data sources (interviews, observation, documents, artifacts) to produce a holistic understanding of a bounded phenomenon within its real-world context.	Field notes are detailed written records created by researchers during or immediately after direct observation in a naturalistic setting. They capture what is seen, heard, and experienced — including behaviors, interactions, physical environments, and the researcher's own analytic impressions — forming the primary data source for ethnographic and observational studies.
