The aim of this study is to design and develop a Physically Interactive Learning Environment, the PILE system, by integrating video-capture virtual reality technology into a classroom. The system is designed for elementary school level English classes where students can interact with the system through physical movements. The system is designed to…

Standard item response theory (IRT) models posit latent variables to account for regularities in students' performance on test items. They can accommodate learning only if the expected changes in performance are smooth, and, in an appropriate metric, uniform over items. Wilson's "Saltus" model extends the ideas of IRT to development that…

The intent of this study was to explore the intrinsic aspects of motivation, and to see if the design of instruction could positively affect learners' levels of intrinsic motivation toward the subject matter. The following questions were addressed: (1) Will different computer-based instructional treatments which have been designed to reflect…

The Mantel-Haenszel procedure (N. Mantel and W. Haenszel, 1959) and its extension to constructed response items, the Generalized Mantel Haenszel (A. Agresti, 1990), compare performance of subgroups across different score groups to determine differential item functioning (DIF). At each level of comparison, or score group, the subgroups are…

A way to support the educational ethnographer in developing a perspective on the art of qualitative research during an introductory course on qualitative research methods is explored through a study of how novice researchers begin to learn the elements and processes of qualitative research. A second purpose of the study is to investigate the use…

The Simulated Oral Proficiency Interview (SOPI) is a semi-direct performance-based speaking test that emulates the face-to-face Oral Proficiency Interview (OPI) as closely as practical, using a tape recording and printed test booklet. The prototypical SOPI contains simple personal background questions typical of an initial encounter (warm-up) and…

A confirmatory approach to assessing test structure using multidimensional item response theory (MIRT) was developed and evaluated. The approach involved adding to the exponent of the MIRT model an item structure matrix that allows the user to specify the ability dimensions measured by an item. Various combinations of item structures were fit to…

The ways in which experience and academic training influence the types of questions therapists ask of their clients were studied. Psychologists and psychology students of varying degrees of expertise (n=138) were provided an artificial intelligence program that simulated a date rape client's responses to typed questions and were asked to conduct a…

Binary or graded disagree-agree responses to attitude items are often collected for the purpose of attitude measurement. Although such data are sometimes analyzed with cumulative measurement models, recent investigations suggest that unfolding models are more appropriate (J. S. Roberts, 1995; W. H. Van Schuur and H. A. L. Kiers, 1994). Advances in…

A study analyzed student delays in flight certification at 106 University Aviation Association (UAA) member postsecondary institutions. After a pilot survey of 5 institutions, questionnaires were mailed to the 101 remaining UAA administrators; 80 responses were returned. Correlations of items in the survey were analyzed and significant…

This research explored the degree to which group sizes can differ before the robustness of analysis of variance (ANOVA) and analysis of covariance (ANCOVA) are jeopardized. Monte Carlo methodology was used, allowing for the experimental investigation of potential threats to robustness under conditions common to researchers in education. The…

This monograph presents a rationale for proactive social skills training for persons with mental retardation as well as over 100 examples of such instruction across the K-12 continuum. Chapter 1 provides a conceptual framework of social competence with principles of what, when, and how to teach social skills. Chapter 2 discusses the direct…

Fit analysis is widely performed in item response theory (IRT) based test development to assess the fit of individual items to the IRT model being used. The paper explores a step fit analysis procedure that is an extension of IRT-based item fit diagnostics applied to the response categories present in popular performance-based tasks. The step fit…

Test-retest reliabilities and practice effect magnitudes were considered for nine computer-simulated tasks of everyday cognition and five traditional neuropsychological tests. The nine simulated everyday memory tests were from the Memory Assessment Clinic battery as follows: (1) simple reaction time while driving; (2) divided attention (driving…

Current omnibus procedures for the analysis of interaction effects in repeated measures designs which contain a grouping variable are known to be nonrobust to violations of multisample sphericity, particularly when group sizes are unequal. An alternative approach is to formulate a comprehensive set of contrasts on the data which probe the specific…
