"Spatial analysis" is an analytic method that uses location-based variables or maps to understand how places, the characteristics of places, and the people and things in places are arranged in space, as well as the reasons for these arrangements. This resource focuses on how spatial analysis can be used to understand early care and…

This comprehensive "Handbook" focuses on the most used polytomous item response theory (IRT) models. These models help us understand the interaction between examinees and test questions where the questions have various response categories. The book reviews all of the major models and includes discussions about how and where the models…

Few methods have been tried and used to graphically represent more than two variables. This poster session showed a new method for representing three continuous variables on a single scatterplot using the THREEDE computer program. Two variables are represented as a normal bivariate distribution. The third variable is represented by a symbol, e.g.…

The overall poor quality of educational software on the market suggests that educators must continue efforts to evaluate available packages and to disseminate their findings. In this paper, weaknesses in published evaluation procedures are identified, and an alternative model, the York Educational Software Evaluation Scale (YESES), is described.…

Describes the use of ALSCAL, a computer program for multidimensional scaling, to map enrollment in 49 electives at Drexel University's College of Information Studies during two time periods. The results for this department are presented, and the explanatory power of this evaluation technique for any curriculum is discussed. (6 references) (CLB)

One of the important underlying assumptions of all item response theory (IRT) models is that of local independence. This assumption requires that the response to an item on a test not be influenced by the response to any other items. This assumption is often taken for granted, with little or no scrutiny of the response process required to answer…

This experiment examined the relationship between computer programming and the following factors: mathematical ability, locus of control, introversion/extraversion, anxiety, and task time allocation. The programming performance of 14 male and 18 female students in a college-level introductory computer science course was measured by means of a math…

The TESTFACT computer program and full-information factor analysis of test items were used in a computer simulation conducted to correct for the guessing effect. Full-information factor analysis also corrects for omitted items. The present version of TESTFACT handles up to five factors and 150 items. A preliminary smoothing of the tetrachoric…

Describes survey conducted among humanities faculty at University of Illinois at Urbana-Champaign to assess their current use of and attitudes toward educational computing. Topics covered on the questionnaire include computer experience, skills and frequency of use, computer interest and anxiety, computer software, and use for instructional,…

This study examined the effect of type of correlation matrix on the robustness of LISREL maximum likelihood and unweighted least squares structural parameter estimates for models with categorical manifest variables. Two types of correlation matrices were analyzed; one containing Pearson product-moment correlations and one containing tetrachoric,…

Describes program design and presents undergraduate students' opinions of computer tutorial--"GROWTH"--used to replace teachers in mastery learning experience. Student reactions were favorable to the program, which stimulated small tutorial group formation. Although females and younger students had more difficulty answering program…

This is the second of two reports on the first year activities and results of the Systems Thinking and Curriculum Innovation Project (STACI), a two-year project which is examining the cognitive demands and consequences of using the STELLA (Structural Thinking Experimental Learning Laboratory with Animation) software to teach systems thinking,…

The purpose of this study was to adapt the Hidden Figures Test (a measure of field dependence/independence) to microcomputer display and to assess its alternate form reliability when compared to a paper and pencil test. Participants included 58 undergraduate and graduate students (91.4% female) at a southeastern university who were fairly normal…

Four writing samples were obtained from 638 foreign college applicants who represented three major foreign language groups (Arabic, Chinese, and Spanish), and from 60 native English speakers. All four were scored holistically, two were also scored for sentence-level and discourse-level skills, and some were scored by the Writer's Workbench…
