Test the ability to design and apply a mixed-methods evaluation of digital learning interventions in higher education. Candidates should demonstrate competence in constructing valid survey instruments, developing semi-structured interview guides, planning sampling and recruitment, extracting and analyzing administrative data (e.g., LMS logs, grades, retention), integrating quantitative and qualitative findings through triangulation, addressing bias and validity threats, managing ethical/IRB concerns, and interpreting results to judge effectiveness and inform practice; provide a brief outline of study design, analytic techniques, and a data-integration strategy for a hypothetical intervention.
