Abstract : The report describes the IMPACT Data Evaluation System--Version 1 (IDES-1); IDES-1 has two main components--storage/retrieval and analysis. The storage/retrieval component is used to update and maintain an extensive data base of Computer-Administered Instruction (CAI) generated data, as well as to retrieve selective data elements from the data base. The data are used for psychological research in learning, and for evaluating the instructional material. In IDES-1, the storage/retrieval function is performed through a list processor, SLIP. IMPACT's version of SLIP has been modified and extended for more efficient operation. The analysis function in IMPACT is intended to provide statistical analysis of data base subsets. This function is performed through the BMD statistical analysis package, augmented by specially prepared programs. This document describes in detail the storage and retrieval portion of IDES-1 (SLIP itself and the BMD package are not described). Listings for 6 computer programs and 29 routines are included. These are written in FORTRAN 4 and PL/1 for IBM 370 computers. (Author)
