Image: Jonathan Turk (Ph.D. 2016) published an article in Research in Higher Education, entitled "Estimating the Impact of Developmental Education on Associate Degree Completion: A Dose–Response Approach.” https://doi.org/10.1007/s11162-019-09549-9 Pulling data from the Education Longitudinal Study of 2002 (ELS) and the accompanying Postsecondary Education Transcript Study (PETS), Turk used propensity score matching for "multivalued treatment conditions or dose–response analysis to the study of developmental education in order to estimate the average causal effects of enrolling in various quantities of developmental education on associate degree completion." The research found that developmental education generally improved the chances of earning an associate degree, and his dose–response analysis revealed a non-linear relationship between the number of developmental courses taken and degree completion.
