The impact of a new science curriculum on students' critical thinking skills was investigated using a randomized controlled study. The curriculum was randomly assigned to buildings and data were collected on all students in the building. A structural equation model is used to model students' latent abilities and evaluate correlations between Science, Math, and Reading abilities on the Iowa Test of Basic Skills. Quantile regression is incorporated into the structural equation model to further dissect the effect of the curriculum on students at various percentiles. The effect of the new curriculum on critical thinking and students' ability to transfer knowledge across subjects, particularly for students in the tails of the distributions, are the primary interests of the study.
