Creativity is a valuable skill for instructional designers. However, few studies have researched creativity in instructional design (ID) graduate courses. Future professionals' creative thinking is necessary to address societal, technological, and economic challenges. Developing creative thinking in novice instructional designers could allow them to generate creative solutions to ill-structured problems in real-world contexts. This multiple case study investigated the extent to which the nine core courses in an online instructional design master's program encouraged creativity. We conducted a document analysis of course materials for each course, to analyze whether creativity indicators derived from creativity literature were present. Subsequently, a cross-case synthesis was used to identify patterns across the cases. Semi-structured interviews of the lead course instructors were conducted to evaluate the extent to which they deliberately included creativity concepts into the course design process. Results indicated core courses include learning activities and instructional strategies with the potential to foster creativity. However, explicit references mentioning creativity or being creative were only found in three courses. Lead instructors considered creativity an important aspect of teaching and learning and a concept that needs to be further developed and discussed in ID education. Implications for instructional design education are discussed.
