The document discusses mixed methods research designs, meta-analyses, and literature reviews. It notes that mixed methods designs typically combine quantitative and qualitative research to provide a broader understanding of a phenomenon. Meta-analyses use statistics to examine patterns across quantitative studies. Literature reviews survey research on a topic but do not statistically analyze studies. The document also provides guidance for writing a blog post reflecting on a literature review and how it informed instructional practices, and for planning an intervention that is informed by research.
