Diagnostic classification models (DCMs) classify examinees based on the skills they have mastered given their test performance. This classification enables targeted feedback that can inform remedial instruction. Unfortunately, applications of DCMs have been criticized (e.g., no validity support). Generally, these evaluations have been brief and…

The authors of this article consider how education researchers can improve school violence and school safety research by (a) examining gaps in theoretical, conceptual, and basic research on the phenomena of school violence; (b) reviewing key issues in the design and evaluation of evidence-based practices to prevent school violence; and (c)…

The formula is simple: Highly effective teachers equal student academic success. Yet, the physics of American education is anything but. Thus, the question facing education reformers is how can teacher effectiveness be accurately measured in order to improve the teacher workforce? Given the demand for objective, quantitative measures of teacher…

This paper presents an analysis of the stability of principal components. Stability is measured by the expectation of the absolute inner product of the sample principal component with the corresponding population component. The usefulness and predictive validity of the model were supported through simulation. (SLD)

This paper proposes a model to establish which criteria are considered by stakeholders as valid for evaluating a program. The model is developed with the aim of increasing the credibility and use of evaluations. Stakeholders are involved in the identification of potential evaluation criteria, and ratings of validity and priority are used as the…

Developed a needs-assessment model and validated the model with five groups of stakeholders connected with an undergraduate university nursing program in Canada. Used focus groups, questionnaires, a hermeneutic approach, and the magnitude-estimation scaling model to validate the model. Results show that respondents must define need to clarify the…

Assessment systems to measure high educational standards emerged as the major theme at the 1996 conference of the National Center for Research on Evaluation, Standards, and Student Testing (CRESST), "Moving Up to Complex Assessment." This feature article, providing a summation of the proceedings of the conference, reports that the…

A model for evaluation of complex educational settings is proposed. The model covers measurement, judgment, and decision making and the related criteria of reliability, validity, and utility. A second proposed model depicts the provincial educational setting. The development of a provincial item bank illustrates the application of the models. (TJH)

Seven chapters present 31 propositions challenging traditional ideas about the nature and practice of program evaluation. Methods to improve evaluation models and approaches and ways to address intermediate and advanced evaluation issues are explored. The discussion also serves as an introduction to the most analytical and comprehensive of the…

This paper examines possible explanations for the fact that evaluation results are rarely used. Most explanatory factors for use of results in decision making mentioned in the literature have been clustered in three categories of variables. They concern: (1) the making of decisions about the practical problem; (2) the way in which evaluation is…
