This instruction book was authored by Siegfried Engelmann, who, among others, developed Direct Instruction. In the late 60s/early 70s there was a thorough comparison of various teaching methods called Project Follow-through; Direct Instruction did far better than all of the other methods. The results of this study were devoutly ignored by the educational establishment, and often denigrated as being "authoritarian".
Englemann, along with another educational researcher, Douglas Carnine, authored a work called Theory of Instruction, which is as disciplined and scientific a work as you can find in a "soft" subject like education, and expounds the theoretical basis behind their effective methods.
