What is I-E-O Model

Researchers and practitioners have come to understand adult learners as unique and different from child learners, and have developed different theoretical approaches, methodologies, and strategies attuned to their educational needs and life circumstances. This chapter examines the factors that impact the effectiveness of adult learning programs and classroom environments by using perspectives of education theorists. The needs of the adult learner, advantages of teaching adults, and principles that can be followed are explored with the help of Knowles' andragogy model. The importance of the classroom's eco-behavioral features—their physical and emotional environments—along with other factors that effectively facilitate the process of adult education are discussed. In this context, an adaptation of Astin's I-E-O's model is proposed to deepen the understanding of adult learning programs.
