CHDS Director Sue J. Goldie and Senior Research Scientist Eve Wittenberg collaborated on the first on-line introductory course on decision science offered at Harvard. RDS 202, Decision Science for Public Health, was launched in Spring, 2017, for students in the MPH-epidemiology degree program. Designed to introduce students to the methods and applications of decision analysis and cost-effectiveness analysis in clinical and public health decision making, the course used multimedia videos, on-line resources, discussion boards, and traditional homework exercises to build skills in decision analysis and economic evaluation methods. Professor Goldie was thrilled with the results of the offering, noting that students achieved exceptional results on the exams measuring competence in the basic decision analytic skills the course taught. Goldie and Wittenberg plan future on-line education leveraging the lessons learned in this endeavor.
