An overview of the field of adult education is presented, and the nature of adult learners and eight basic instructional modes are discussed. The focus is skills that make people better teachers and the intended audience is college professors, continuing education instructors outside the formal education setting, and students of higher education. Of concern are the following instructional modes: lecture, discussion, tutorial, self-instruction, programmed book, materials instruction, medium instruction, laboratory, and combinations of these. Also considered is a theoretical base for adult learning, with attention to the ideas of Malcolm Knowles. The theoretical model considers: the concept of a learner, the experience of the learner, learning readiness, orientation toward learning, and motivation to learn. Also addressed are: special groups of learners (e.g., older students, students in literacy programs, slow learners); evaluation of student achievement; reporting and crediting performance; and program/course/instructor evaluation. A sample evaluation form is included. (SW)
