Assess the student's ability to design a comprehensive graduate-level research plan to develop and validate a scalable, culturally responsive competency-based STEM curriculum for urban high schools. The plan should specify curriculum design principles grounded in equity and competency-based education; procedures for instrument development with a validity argument and reliability evidence; a cluster-randomized trial design addressing sampling, power, randomization strata, and implementation logistics; a hierarchical Bayesian analysis plan for multi-level impact estimation (including priors, model specification, and decision rules); procedures for fidelity monitoring and adaptive supports; and a cost-effectiveness evaluation with costing methods and sensitivity analyses. Require justification of methodological choices, measurement strategies, analytic plans, scaling pathway, and policy implications.
