TEACHING MACHINES

We shall see, however, that Wohlwill finds a basis for challenging Skinner 's application of this second principle to human conceptual learning . The article on teaching machines reprinted here from Science was important in bringing Skinner 's views on education before scientists of many fields at a time when they were becoming interested in and involved with the way their own disciplines were being taught at the elementary and secondary levels. This article restates Skinner 's earlier stand and contains in addition a discussion of some intervening developments. Whatever your own current view of programmed instruction, you will find that Skinner 's article raises a number of important questions for education. First, it is an interesting proposition that it is impossible for a teacher alone to reinforce any but a tiny proportion of the hundreds of thousands of appropriate responses made by a class of children in the course of the academic year. 1. Does this proposition seem reasonable? Assuming that these responses should be reinforced, are there any ways of accomplishing this other than by machine? 2. If a machine is used, how should the programs be selected for each child? Skinner contends that a device is necessary "if each student is to have individual attention." 3. A program can be selected by the teacher specifically for the individual student, but to what extent does a program give the student individual attention? 4. We continually urge students to organize material in order to remember it. Do different students have different ways of organizing, and will the organization inherent in a particular program work well for all ? Skinner suggests that, with programmed instruction, all students can get an A
