We conducted a field experiment testing whether a theory-based intervention designed to help parentsconvey the importance of mathematics and science courses totheir teens would lead their teens to take more mathematics andscience courses in high school. The three-part interventionconsisted of two brochures mailed to parents and a website, all highlighting the usefulness of STEM courses. This relatively simple intervention led students whose parents were in the experimental group to take on average nearly one semester more of science and mathematics in the last 2 years of high school, compared with the control group. Parents are an untapped resource for increasing STEM motivation in adolescents, and the results demonstrate that motivational theory can be applied to this important problem.
Under review.
