Abstract:
|
In a longitudinal cluster randomized trial, we investigate the impact of a new inquiry-based approach to teaching science, the science writing heuristic, on student's math, reading, and science test scores. There are 48 elementary schools (clusters) from Iowa participating in the study, with a total of roughly 2300 students per grade (third, fourth and fifth) per year enrolled in the schools. We are primarily interested in effect of the science writing heuristic on student-level outcomes over time. A multivariate longitudinal regression model (Shah et al 1997, Wu et al. 2009) is selected to simultaneous address correlation in the responses, non-ignorable missing data, and time dependence in the covariates.
