Based on recording transcriptions of Ralph W. Tyler's responses to questions by a panel of University of Wisconsin-Extension professors in July 1973, this booklet is presented as an extension of what Tyler has to say in his book, "Basic Principles of Curriculum and Instruction" (University of Chicago Press)--but said in the context of extension and adult education. Questions with Tyler's answers are organized into four chapters, each with an editor's introduction: (1) Learning Experiences--regarding how it may be possible to provide the kinds of activities that have the potential for facilitating others in learning, (2) Determining the Things to be Learned--the question of moving from the establishment of needs, relevance, and determining priorities to the determination of things program participants will be assisted in learning, (3) Needs, Relevance, and Priorities--the matter of identifying and utilizing needs, establishing relevance, and determining priorities as the basis for programing, and (4) Evaluation--the question of what to look for in evaluating efforts as educators, both in terms of the eventual consequences and of what happens in the process.
