This paper discusses one practical difficulty that emerges when teachers begin to construct learning modules: that most module developers make the error of becoming "course choppers" rather than "system builders." The paper is written for teachers who have begun the process of developing modules and have encountered organizational difficulties. The paper stresses learner reinforcement: the teacher must see how the pieces of the course will fit together and the learner must reinforce himself/herself through a selection of motivational experiences coordinated into a coherent system by the teacher. The paper is presented in a question and answer format. The questions are the types that teachers ask when presented with modular instruction as an alternative approach to teaching, and the answers are those developed by teachers to explain this approach to one another.
