This handbook was written to inform and raise questions among volunteers and paid staff who are new to teaching the undereducated adult learner. In its five sections the handbook discusses some of the more frequently observed characteristics of the undereducated adult, and the implications of these characteristics for adult education teachers as they work to create a supportive environment for profitable learning experiences for their students. The handbook also notes some important differences between adult and child learners, and presents some considerations and suggestions to increase the likelihood of a positive teaching/learning situation.
