In this study, self-reports of 34 individuals with developmental disabilities (DD) were compared with proxy ratings from family and providers. Correlations between the ratings of individuals with DD and the proxy raters were low, as were the correlations between family members and providers. In all scales except "cognition," the individual with DD…

Infant-control habituation methodology, although serving the research community well, has never been carefully analyzed. A main use is to equate infants in their level of habituation prior to experimental manipulations in a posthabituation phase. When studied analytically and with simulation, it is found to have serious difficulties. It…

Government and public focus on accountability for program outcomes, combined with practical and ethical constraints on experimental designs, make nonexperimental studies of social programs an increasingly common approach to producing information on program performance. In this paper, we compare the effectiveness of alternative nonexperimental…

This article discusses the current issues involved in the evaluation of children who have both intellectual gifts and a specific learning disability (SLD) in reading. Given recent changes in federal special education law (i.e., the Individuals With Disabilities Education Improvement Act of 2004), the use of a unified assessment model that…

This volume gives language teachers, software designers, and researchers who wish to use technology in second or foreign language education the information they need to absorb what has been achieved so far and to make sense of it. It is designed to enable the kind of critical reading of a substantial literature that leads to a balanced and…

This article briefly reviews the central ideas associated with the notion of systemic reform and indicates how these ideas are manifested in the draft of the National Science Education Standards. The draft is critiqued and what the critique suggests about the viability and utility of the notion of systemic reform is considered. The discussion…

A scaling procedure has been developed for ordering binary parallelogram preference data. The procedure uses minimum variance of the item ranks averaged across persons as the optimization criterion. Two seriation strategies are employed. One is pairwise interchange. The second joins together the vector end points and breaks this circle between…

Designed to provide teachers in early childhood education and other interested educators with criteria for evaluating the quality of plot, characterization, and style in picture story books, this instrument uses a set of eight criteria for evaluating these literary elements. Each criterion is followed by statements that illustrate different ways…

Principles of program evaluation research are outlined so that bilingual education program coordinators can conduct methodologically acceptable program evaluations. The three basic principles of evaluation research are: identification of the program participants, definition of the program intervention, and assessment of program effectiveness.…

The dissemination of successful educational innovations has long been a strongly supported policy in educational settings. Recent research developments have led to a debate as to the appropriateness of a centralized versus decentralized dissemination policy. The current research provided a test of the modified Research, Development and Diffusion…

The purpose of this study is to explore the potential uses of photography and its practical implications as a qualitative evaluation technique. Potential uses are proposed: (1) systematic recording of a program activity; (2) highlighting specific events; (3) illustrating a point; (4) leading the evaluator to specific persons, activities, and…

A new indicator of item difficulty, which identifies effectiveness ranges, overcomes the limitations of other item difficulty indexes in describing the difficulty of an item or a test as a whole and in aiding the selection of appropriate ability level items for a test. There are three common uses of the term "item difficulty": (1) the probability…

This paper describes how a naturalistic inquirer can demonstrate rigor, or trustworthiness, and how an auditor might assess it. Looking at both inquiry products and processes, Part 1 of this paper describes how an audit may assess whether an inquiry's findings and conclusions are grounded in the raw data, and whether appropriate conventions were…

The materials in this paper were drawn from an action caucus called to seek common criteria for the presentation and judging of oral interpretation and forensic tournaments. The first section of the paper consists of presentations made by participants. Topics covered in these presentations are (1) consistency in judging, (2) the role of oral…

Previous research on performance evaluation systems has failed to take into account user acceptance. Employee acceptance of a behaviorally-based performance appraisal system was assessed in a field experiment contrasting user preference for Behavioral Expectations Scales (BES) versus Behavioral Observation Scales (BOS). Non-union sales associates…
