Understanding adult learning motivations must be grounded in the understanding of adult learning theory. The doctoral theses I write are called Knowledge Area Modules (KAMs). The first 30 pages represent the theoretical underpinnings that support or discredit current practices. A minimum 15 resource bibliography of current practices written in the past five years is then required followed by a 20-25 page literature essay that connects the theory and practice. Following that is a proposed experiment, case study, or research project to address a gap discovered. I cannot overstate the value in this approach, and the practical knowledge and application immediately discovered throughout the process. A PhD that practices the theory it teaches? Yes!
Meanwhile, my first KAM discussed adult learning theory, the subsequent impact of adult learning motivation and need for instructional strategies to address that motivation positively. This video is something that I put together that provides the 15 minute context and introduction to adult learning motivations supported by theory.
