Configural frequency analysis and log-linear modeling are presented as person-centered analytic approaches for the analysis of categorical or categorized data in multi-way contingency tables. Person-centered developmental psychology, based on the holistic interactionistic perspective of the Stockholm working group around David Magnusson and Lars…

In this article, a Bayesian model selection approach is introduced that can select the best of a set of inequality and equality constrained hypotheses for contingency tables. The hypotheses are presented in terms of cell probabilities allowing researchers to test (in)equality constrained hypotheses in a format that is directly related to the data.…

The evidence that teacher preparation programs have an impact on teacher quality is often limited. Progress in research on this topic will remain rather limited in its influence on practice until more proximal measures of teacher education outcomes can be established. The dearth of variables to measure the impact of teacher preparation programs on…

The procedures required to obtain the approximate posterior standard deviations of the parameters in the three commonly used item response models for dichotomous items are described and used to generate values for some common situations. The results were compared with those obtained from maximum likelihood estimation. It is shown that the use of…

Discusses research with neural networks in the area of finance. Highlights include bond pricing, theoretical exposition of primary bond pricing, bond pricing regression model, and an example that created networks with corporate bonds and NeuralWare Neuralworks Professional H software using the back-propagation technique. (LRW)

Discusses use of the computer to solve the specific scheduling problems in assigning umpires to American League baseball games and assigning crews of officials to Atlantic Coast Conference football and basketball games. Scheduling variables that complicate the process and make manual scheduling almost impossible are described. (MBR)

Describes a method for inducing a theoretical model of a series of events that occur in an ongoing process. A data analysis method that transforms narrative data into event histories is explained, a spreadsheet display that compares event histories is described, and future research is suggested. (17 references) (LRW)

Presents the results of a comparative evaluation of four CD-ROM retrieval software packages using the Revised Richards-Brown CD-ROM Software Evaluation Model. CD Answer, SPIRS, KAware2, and ROMware are evaluated, and results indicate that SPIRS and CD Answer are the favored packages. (LRW)

Discusses current use of psychological theory in software science and reviews recent developments in cognitive psychology relevant to programing (human information processing, expert-novice differences). Critique of Maurice Halstead's model of cognitive aspects of programing and a structured data flow perspective (control flow and data flow…

Analyzes the skill acquisition sequence in using a software package and proposes advent models for investigating patterns of user interaction with information systems. The use of transaction log data is explained, advent function analysis is described, and tests of the models on longitudinal data are discussed. (26 references) (LRW)

This paper discusses the incorporation of heuristics in computerized decision aids that are used for structuring decision problems. Decision theory is described in terms of linked subsystems, and sites where it is necessary to employ heuristic rather than normative, algorithmic procedures are identified. Production systems are then used to…

Creating educational software generally requires a great deal of computer expertise, and as a result, educators lacking such knowledge have largely been excluded from the design process. Recently, researchers have been designing tools for automating some aspects of building instructional applications. These tools typically aim for generality,…

Examines mobile agent coordination and presents TuCSoN, a coordination model for Internet applications based on mobile information agents that uses a tuple centre, a tuple space enhanced with the capability of programming its behavior in response to communication events. Discusses the effectiveness of the TuCSoN model in the contexts of Internet…

Discusses areas affecting instructional material selection (district educational policy, curriculum, student and teacher characteristics, and community concerns); describes phases of the material selection process (screening materials, matching materials to needs, and decision making); and applies this conceptual scheme to selection of basal…

The Appalachia Educational Laboratory (AEL) conducted an assessment of microcomputer-related needs for basic mathematics in the four-state areas of Kentucky, Tennessee, Virginia, and West Virginia in 1984-85. The primary input came from teachers from each of the states who participated in a needs conference in their home state. When each of the…
