The Reduced Reparameterized Unified Model (Reduced RUM) is a diagnostic classification model for educational assessment that has received considerable attention among psychometricians. However, the computational options for researchers and practitioners who wish to use the Reduced RUM in their work, but do not feel comfortable writing their own…

Provides brief descriptions of interactive tutorial and simulation programs for reading, writing, and mathematics; and of drill-and-practice courseware packages. (DMM)

This Digest points out characteristics of quality computer software for children, describes different kinds of software, and suggests ways to get software for preview. The need to consider the purpose for which the software is to be used and the degree to which the software meets its stated goals is noted. Desirable software characteristics and…

Research on structural learning theory is reviewed as a base for designing computer-assisted instruction programs. An intelligent "Rule Tutor" emphasizing diagnosis and remediation for whole number concepts is described. (MNS)

Computers can be used to teach reading to reading-disabled students in three modes: the tutor mode, tool mode, and tutee mode. The computer's ability to improve motivation and to provide versatility is examined. A vignette is presented of computer use in the instructional program of a reading-disabled nine-year-old.

The development of templates for computer-assisted language learning (CALL) is discussed, based on experiences with primarily linear multimedia tutorial programs. Design of templates for multiple-choice questions and interactive tasks in a prototype module is described. Possibilities of enhancing interactivity by introducing problem-oriented…
