| সারসংক্ষেপ≠ | Multiple case-based oral history is a qualitative research design that embeds oral history interviews within a multiple-case framework. Rather than collecting testimonies from a single community or site, the researcher deliberately selects two or more distinct cases — communities, cohorts, organisations, or geographic sites — gathers in-depth oral testimonies within each, and then conducts systematic cross-case comparison to identify both shared and divergent historical experiences. | 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. |
