Assess the ability to design and apply a mixed-methods research approach to evaluate instructional interventions in higher education. Test tasks include selecting and justifying an appropriate mixed-methods design (convergent, explanatory, exploratory), specifying sampling and measurement strategies, planning complementary quantitative and qualitative data collection and analysis, outlining strategies for data integration/triangulation and ensuring validity, reliability, and ethical rigor, and interpreting hypothetical integrated results into actionable instructional recommendations and policy implications.
