The purpose of the study was to ascertain how online asynchronous security coursework influenced learner's understandings by analyzing their end-of-course reflective writings. Following a qualitative single case study protocol, the researchers set forth to discover how a semester-long asynchronous online security course influenced students. The study took place at a public four-year university located in the Western United States. The 12 participants involved in this study all enrolled in and completed an introductory asynchronous online homeland security class either as part of their major or as a global/intercultural elective. From the data analysis three overarching themes emerged, (a) realization of responsibility and mission, (b) appreciation for new understandings, and (c) new areas of curiosity. The findings of this study begin a dialogue on what specific themes need to be considered when constructing future security and emergency management course offerings in academia.
