🧪 Curriculum Curriculum Evaluation Simulation

This simulation demonstrates the process of evaluating a curriculum's effectiveness using the same statistical logic real education researchers use: generate a cohort of students, give them a pre-test and a post-test around a curriculum intervention, and measure whether the post-test distribution actually shifted. A live 3D histogram renders both score distributions as bar rows, a threshold marker shows the passing cutoff, and the panel tracks mean gain, pass rates and the standardized effect size (Cohen's d) that separates a genuinely effective curriculum from noisy, inconsistent implementation.
