This guide, which was developed by a group of nonformal education (NFE) practitioners during a training course conducted in India, is intended as a tool to train NFE practitioners. Discussed first are the basic principles of NFE, the meaning of the term "active learning and education," features of NFE, and ways NFE can help advance development. The following issues are considered in a section devoted to NFE's social context: involving stakeholders and the community in NFE and NFE centers; building a stronger learning environment and promoting active learning through a process of questioning, thinking, and testing; and motivating learners. Part 3, "NFE and the Classroom" covers topics such as: creating a learner-centered curriculum, syllabus, and schedule of work; setting learning objectives in terms of knowledge, skills, and attitudes; managing the classroom in a manner promoting active learning; and selecting methods and materials for use in learner-centered NFE. The concluding section on developing the future of NFE includes a rationale and procedures for monitoring and evaluating learner-centered NFE and guidelines for incorporating evaluation results into action plans for the future.
