This report documents a computer program for simulation evaluation of item response theory (IRT) ability estimators. This Honeywell DPS version is a very slight modification of the program originally developed in FORTRAN-77 on a DEC VAX 11/780. The model of the world simulated by the program involves a unidimensional test in which the probability…

Focuses on the first of three stages of the path evaluation procedure for instructional software, performing the preliminary evaluation. The three main steps involved in preliminary evaluation are (1) a program is chosen for evaluation; (2) information is exchanged with the faculty developer; and (3) the instructional designer reviews the software…

This study used multiple regression analysis to relate computer user satisfaction to communication monitor (CM) variables. Results indicate the variables of user expectations, manufacturers, and vendors are most significant in affecting overall satisfaction, whereas number of systems represented and not using communication monitors have least…

This description of the design of an online library acquisition system highlights the use of database management systems in developing information retrieval systems, and software requirements for the hierarchical menu-driven operation. A conceptual view of the database is included. (LRW)

Discussion of past, present, and future of computer-based teaching at the undergraduate level addresses psychological, economic, and political barriers to progress; educational potential and objectives; technological developments and new organizing principles in software fostering computer-based teaching; and correct environment, support,…

Considers possibility of developing a computer tutor around an explicit concept-learning theory derived from machine learning techniques. Some problems with using the focusing (and similar) algorithms in this role are discussed and possible solutions are developed. Design for a guided discovery learning system for tutoring concepts is proposed.…

Identifies technical and linguistic problems associated with use of Arabic in input and output devices and describes efforts to introduce a unified code for the Arabic language (CODAR-U/FD). The Hydriyya Method, requirements for Arabic terminals suitable for library use, manufacturers of bilingual terminals, and Arabization of software are…

Describes a Centre Mondial Informatique et Resources Humaines (CIMRH) investigation of kindergarten children's written language learning and links between play and learning. Computer software was used by students for language learning, and observations centered on student computer use, learning of written language and play, and computer…

School psychologists and education students and faculty were asked to distinguish between computer-generated and individually written psychological test comments and indicate cues used in making identifications. Even though results indicate correct identification did not differ significantly from chance, school assessment reports must provide more…

Reviews literature on conceptual conflict as facilitator of student learning and alternative conceptions, describes theories explaining occurence of alternative conceptions and conflict role in conceptual change, discusses a model of learning as conceptual change and its instructional implications, and presents results of studies which apply the…

The purpose of this paper is to describe some of the current changes in test development that are taking place because of the availability and capabilities of computers, especially microcomputers. Item banking and test assembly are discussed, and a comprehensive testing system is described. (BW)

In the field of computer aided language learning (CALL), there is a need for emphasizing the importance of the user. "User-Centered Computer Aided Language Learning" presents methodologies, strategies, and design approaches for building interfaces for a user-centered CALL environment, creating a deeper understanding of the opportunities and…

This article develops an algorithm to find all solutions to the problem, making all sums of a hexagram's nine lines the same. It shows how to exploit the geometric structure of the hexagram and its group of automorphisms. (YP)

The teaching and learning potential of interactive video (IV) are explored. Some of the programs currently in use are described. The use of IV for simulations, practical work, problem solving, and presentational skills are discussed. (KR)

Part of the Communications Design Center's (CDC) on-going research on communication and document design, this report emphasizes the importance of a multi-level computer help system that goes beyond simple command descriptions to include assistance with goals and strategies within the application domain--in this case, automated authoring. The help…
