While doctoral leadership programs have widely adopted Improvement Science (IS) as a signature pedagogy, few studies have examined how to best equip doctoral students with the knowledge and research skills they need to utilize IS in practice. More specifically, research is needed to determine the most effective and meaningful pedagogy for preparing doctoral students to understand, analyze, and apply statistical theory and quantitative research designs in coursework and as part of the IS Dissertation in Practice. This essay focuses on the systematic, iterative, and reflective approach of one faculty member to develop and refine a Doctor of Education program's primary applied quantitative methods course to help students across three cohorts develop the theoretical and practical knowledge and skills they need to lead change.
