Expanding pathways to clinical and translational research training with stackable microcredentials: A pilot study.

Introduction: The proportion of physician-investigators involved in biomedical research is shrinking even as the need for high-quality, interdisciplinary research is growing. Building the physician-investigator workforce is thus a pressing concern. Flexible, "light-weight" training modalities can help busy physician-investigators prepare for key stages of the research life cycle and personalize their learning to their own needs. Such training can also support researchers from diverse backgrounds and lighten the work of mentors.

Materials and methods: The University of Pittsburgh's Institute for Clinical Research Education designed the Stackables Microcredentials in Clinical and Translational Research (Stackables) program to provide flexible, online training to supplement and enhance formal training programs. This training utilizes a self-paced, just-in-time format along with an interactive, storytelling approach to sustain learner engagement. Learners earn badges for completing modules and certificates for completing "stacks" in key competency areas. In this paper, we describe the genesis and development of the Stackables program and report the results of a pilot study in which we evaluated changes in confidence in key skill areas from pretest to posttest, as well as engagement and perceived effectiveness.

Results: Our Stackables pilot study showed statistically significant gains in learner confidence in all skill areas from pretest to posttest. Pilot participants reported that the module generated high levels of engagement and enhanced their skills, knowledge, and interest in the subject.

Conclusions: Stackables provide an important complement to formal coursework by focusing on discrete skill areas and allowing learners to access the training they need when they need it.
