Johan N. M. Lagerlöf and Andrew J. Seltzer (2009), “The Effects of Remedial Mathematics on the Learning of Economics: Evidence from a Natural Experiment”. Journal of Economic Education, 40(2): 115-137 (lead article).
Abstract The authors examined the effects of remedial mathematics on performance in university-level economics courses using a natural experiment. They studied exam results prior and subsequent to the implementation of a remedial mathematics course that was compulsory for a sub-set of students and unavailable for the others, controlling for background variables. They found that, consistent with previous studies, the level of and performance in secondary-school mathematics have strong predictive power on students’ performance at university-level economics. However, they found relatively little evidence for a positive effect of remedial mathematics on student performance.
