In this study, 82 middle and high school teachers engaged with the InSTEP online professional
learning platform to develop their expertise in teaching data science and statistics. We
investigated teachers’ engagement within the platform, aspects of the platform that were most
and least effective in building teachers’ expertise, and the extent to which teachers’ self-efficacy
changed. Using mixed methods, we collected, analyzed and integrated multiple data sources.
