An Experiment in a Coeducational University}, year={2013}, month={Feb}, institution={Institute of Labor Economics (IZA)}, address={Bonn}, type={IZA Discussion Paper}, number={7207}, url={https://www.iza.org/index.php/publications/dp7207}, abstract={We examine the effect of single-sex classes on the pass rates, grades, and course choices of students in a coeducational university. We randomly assign students to all-female, all-male, and coed classes and, therefore, get around the selection issues present in other studies on single-sex education. We find that one hour a week of single-sex education benefits females: females are 7% more likely to pass their first year courses and score 10% higher in their required second year classes than their peers attending coeducational classes. We find no effect of single-sex education on the probability that a female will take technical classes and there is no effect of single-sex education for males. Furthermore we are able to examine potential mechanisms driving the single-sex effect for females. We find that the results are consistent with a reduction in stereotype threat for females and are not due to a potential tracking effect.}, keywords={education;single-sex;experiment;gender}, }
