This guide for teachers considering using independent learning describes the Keller Plan and describes ways in which it has been adapted for use in a variety of school situations. A discussion of the Keller Plan and its original formulation is followed by six case studies written by teachers in schools and colleges describing their use of the Keller Plan. The first four case studies deal with the implementation of the Keller Plan in physics courses and the fifth in a chemistry course. Each describes how teachers introduced it into schools were timetabling and other constraints led to a number of modifications to the plan; the sixth study describes how the plan was introduced and organized in a Further Education College where the constraints were quite different. The last chapter comprises a report on a seminar organized by the Scottish Council for Educational Technology and attended by all of the teachers who had written the case studies. This seminar provided a forum for discussion of the case studies and generalizations about the Keller Plan in the classroom were made based on the experience of the participants. A list of 10 references is included. (CHC)
