Abstract
This Special Section represents a “first” for the JEE. In previous issues the “Communications” section has often included comments and criticisms of previously published articles, and authors of the original pieces have sometimes replied to these criticisms. Initially, the intention was to treat Becker's comment on Soper's article “Programmed Instruction in Large-Lecture Courses” (JEE, Spring 1973) in the conventional way. It was finally decided, however, that the exchange between Becker and Soper, and Highsmith's reaction to both papers, was important enough to merit special treatment. The research techniques discussed in the three papers should be of great interest to all who are involved in economic education research and, indeed, to all who read the reports of such research.
