Book excerpt: By exploring how the religious beliefs, scientific knowledge, and social surroundings of African-American sufferers of type 2 diabetes mellitus (T2DM) impacts their understanding of the condition, this book develops a new model of effective adult learning. Presenting the findings of rigorous qualitative research undertaken with five individuals with T2DM, this volume considers how individuals’ educational background, their personal experiences, and their relationship with African-American theism have impacted on their efforts to understand and manage the disease. Identification of the social and spiritual dynamics which govern adults’ acceptance of a chronic condition such as diabetes, and their ability to manage the illness according to modern medical principles, informs the development of a new theory of adult learning known as permeated learning. This model, which extends beyond transformative learning to recognize the influence of social constructs specific to African-American communities, will have broad application to adult education and the management of chronic diseases. This scholarly text will be of great interest to graduate and postgraduate students, researchers, academics, and policymakers in the field of adult education, African-American education, transformative learning, lifelong learning, and multicultural education.
