Abstract:

The computer-administered instruction CAI language component in Project IMPACTs CAI system is an IBM program product, Coursewriter 3 Version 2, which has been modified slightly at IMPACT. The modifications concern what data are recorded by Coursewriter 3 and how and when data are recorded. The modifications also provided for special handling of invalid sign-on attempts, and special processing of commands and symbols not normally recognized by Coursewriter 3. IMPACT has also developed and has in use several Coursewriter 3 functions for clearing counters and switches, for storing and loading buffers and counters, for special processing of buffers, for processing student response, for recording data, and for performing arithmetic computations on-line. This document provides detailed documentation on all Coursewriter 3 modifications made at IMPACT and on all Coursewriter 3 functions used at IMPACT. Source program listings 74 pages for 12 IBM 370 assembly language routines are included. Author
