The utility of the biomedical model of adjusted statistics is demonstrated. The model is recommended for use by educational researchers to randomize subjects for a more accurate estimate of school programs' success or failure when compared across classrooms or other units. (Author/MH)

More than a dozen statistical models have been developed for the purpose of cognitive diagnosis. These models are supposed to extract a much finer level of information from item responses than traditional unidimensional item response models. In this paper, a general diagnostic model (GDM) was used to analyze a set of simulated sparse data and real…

This study describes the reading and test-taking strategies that test takers used in the Reading section of the LanguEdge courseware (ETS, 2002a). These materials were developed to familiarize prospective respondents with the new TOEFL®. The investigation focused on strategies used to respond to more traditional single selection multiple-choice…

The evaluation report is one of seven produced for the Occupational Exploration Program (OEP), a series of simulated occupational experiences designed for junior high school students. Describing the pilot testing of the simulation dealing with manufacturing production, the report contains sections describing the simulation context, evaluation…

The evaluation report is one of seven produced for the Occupational Exploration Program (OEP), a series of simulated occupational experiences designed for junior high school students. Describing the pilot testing of the simulation dealing with advertising, the report contains sections describing the simulation context, evaluation procedures,…

This article reports on two studies that were conducted to determine whether (a) total enterprise simulations are suitable for assessing business skills and (b) the tournament concept can be effectively applied to such simulations. The first study involved 141 senior business students; the second, 74. The results are consistently favorable on both…

The Second International Conference on Educational Data Mining (EDM2009) was held at the University of Cordoba, Spain, on July 1-3, 2009. EDM brings together researchers from computer science, education, psychology, psychometrics, and statistics to analyze large data sets to answer educational research questions. The increase in instrumented…

Building and evaluating artifacts specifically for K-12 education, technologists committed to design sciences are needed along with an approach to evaluation increasing the systemic transfer from research and development into school settings. The authors describe THE VIRTUAL LAB scanning electronic microscope simulation, including (a) its…

The intent of this document is to describe approximately 30 management science and organizational behavioral techniques with practical applications in school business management. Each technique is described by the mechanics of using the technique, specific applications of the technique, and requirements and constraints in the use of the technique.…

The 7th International Conference on Education Data Mining held on July 4th-7th, 2014, at the Institute of Education, London, UK is the leading international forum for high-quality research that mines large data sets in order to answer educational research questions that shed light on the learning process. These data sets may come from the traces…

The labor market spillover effects of welfare reform were estimated by using models that pool time-series and cross-section data from the Current Population Survey on the state-year cell means of wages, employment, and other labor market outcomes for various demographic groups. The labor market outcomes in question are dependent variables that are…

This manual provides a description of the development and a guide to the use of the assessment resources developed in connection with the Far West Development, Dissemination, and Evaluation (DD&E) Functional Competence Training Program. The document concentrates on a user-oriented description of the content, validation, and use of the final…
