The purpose of PUNCT2-CW is to test the feasibility and practicality of a data base system of computer-assisted instruction in English. To save time and to provide comparison, this course was based on the objectives, format and logic of an earlier course, PUNCT. The present data base is a sentence pool composed of certain sentence patterns called prototypes, each with a unique call number. A program author can call a type of sentence by using the prototype name. By employing certain macros, he can use the sentences from the pool as if they had been hard coded. Original sentences can be quickly and simply added to the pool. Flow charts document the process from the time a sentence is called from the pool until it has been displayed and finally answer processed. The description of how the macros are used, and what must be included in a macro call, is a more detailed account expanding drills and providing new sentences within the already coded data base, but a modified system of macros is needed to simplify recall from the sentence pool. The speed of the system will be improved by translation into the APL programing language. (Author/SL)
