This document discusses using ePortfolios in a Masters course to cultivate learning design thinking. It describes how the course explored learning design models and technologies through enactment, evaluation, and reflection activities. Students designed an online learning intervention and reflected on the process in an ePortfolio. The course addressed the diverse backgrounds of students with varying educational theory and technology experience. Student performance and reflections showed how the iterative process supported developing learning design thinking. The course structure and assessments were adapted based on reflections to better address student diversity.
