Multimethod Generative CAI (Computer-Assisted Instruction) System for Remedial Mathematics

摘要

The Navy needs modern and efficient instructional systems to meet required levels of operational readiness. Recent work in this area has relied heavily on computer-assisted instruction (CAI). Because there are several methods of CAI, some of which still under development or have received little empirical assessment, it is important to determine which methods are most efficient with certain curricula and student groups. The purpose of this effort was to develop a CAI system for use in assessing the relative efficiencies of four modes of teaching remedial arithmetic and algebra. The four modes result from orthogonal variation of two binary dimensions: ad hoc, frame-oriented (AFO) instruction versus information-versus affective instruction. Following a literature review regarding generative CAI systems, a computer-assisted tutorial system for remedial mathematics was written in modified LISP programming language and was installed on the PDP 11/45 computer. The new system was then compared to five generative systems and one problem-solving system to determine its suitability for assessing the four modes for teaching remedial mathematics to navy personnel.
