The purpose of this paper is to provide an overview of Adult Learners; specifically from the scope of the Instructor’s perspective. The goal for this exploration is to determine the most effective teaching methods pertaining to the adult learner. This topic was chosen because I have an interest in teaching undergraduate students at Granite State College, where adult learners are eager to learn. This paper explores theories including Self-Directed Learning Theory, Transformational Learning Theory, The Margin Theory, and specifically Malcolm Knowles’ study of Andragogy. Keller’s ARCS Model is also applicable and considered. End results show that adults learn best in an environment which allows self-directed learning, with the instructor providing the role of the facilitator. This reseach demonstrates that instructors should tailor the course design to students’ needs, life experiences, and interests by using different instructional methods.
