Dr. Mechner wrote this document in late 1961 for the training of Basic Systems programmers, and continued to modify it in1962. The document was also included in the readings Dr. Mechner assigned in the 1963 summer course on Programmed Instruction that he taught at Teachers’ College, Columbia University, and some passages from it were later included in Mechner (1967).
Twenty years later he developed a programmed learning course on behavioral analysis for U.S. Army developers of training materials, under a TRADOC contract. A copy of this course is available in Mechner Foundation archives.
