What research methodology is best for studying the experiences of homeless children in primary school?

Here's why:

• Case-study methodology involves an in-depth, detailed investigation of a single case or a small number of cases. It is particularly well-suited for exploring complex, real-life phenomena and gaining a rich understanding of individual experiences, perspectives, and contexts. The research topic focuses on understanding the "experiences" of a specific group (homeless children), which requires a qualitative approach that can delve into their unique situations and narratives.

The other options are less appropriate:

• Large-scale data analytics and data mining are quantitative approaches used to identify patterns and trends in vast datasets, not to explore individual experiences in depth.
• Programme-wide evaluation is used to assess the effectiveness and impact of a specific program or intervention, which is not the focus of this research topic.
• Reflective methodology typically involves researchers reflecting on their own practices or experiences, rather than systematically exploring the experiences of others.

The correct option is Case-study methodology.
