In this paper, a data perturbation method for minimizing the possibility of disclosure of participants' identities on a survey is described in the context of the National Assessment of Educational Progress (NAEP). The method distinguishes itself from most approaches because of the presence of cognitive tasks. Hence, a data edit should have minimal…

This article presents evidence from a national evaluation of the effects of 21st Century Community Learning Center after-school programs. The study was conducted in 12 school districts and 26 after-school centers, at which 2,308 elementary school students who were interested in attending a center were randomly assigned either to the treatment or…

A new report published by the Buckeye Institute for Public Policy Solutions is a minor variant on six similar reports published by the Friedman Foundation over the past three years. The new report repeats some of the errors in the previous reports, and it follows a parallel structure, arguing that the costs of dropping out are dramatic for the…

Purpose: The purpose of this paper is to examine the relationship of gender, work factors, and non-work factors with aspirations to positions in senior management. A process model of senior management aspirations was developed and tested. Design/methodology/approach: Data were collected via an online survey that resulted in a sample of 368 working…

This guest editorial describes ways teachers can use guessing games about an unknown item in a "mystery box" to help children improve their abilities to listen to others, recall information, ask purposeful questions, classify items by class, make inferences, synthesize information, and draw conclusions. The author presents information…

Purpose: The purpose of this study was to review research published by Educational Administration Quarterly (EAQ) during the past 10 years to determine if confidence intervals and effect sizes were being reported as recommended by the American Psychological Association (APA) Publication Manual. Research Design: The author examined 49 volumes of…

This paper draws on earlier work on ideas that underpin the collection and use of evidence in science in schools. It establishes that different types of practical work share the same procedural underpinnings. It then takes the work of Toulmin on argumentation to suggest that the idea of the "public claim" can be used to forge a link…

Models and modeling are frequently used as instructional tools in science education to convey important information concerning both the explanatory and structural features of topic areas in science. The efficacy of models as such rests almost entirely upon students' ability to conceptualize them as abstracted "representations" of…

Noting that although some children read aloud with apparent fluency, they fail to understand fully or remember connected discourse, this book brings together research on children who have a specific comprehension deficit. The book first provides an introduction and overview of adult and child text comprehension, and then describes the research.…

Two analyses of variance (ANOVA) models for item scores are compared. The first is an items by subject random effect ANOVA. The second is a mixed effects ANOVA with items fixed and subjects random. Comparisons regarding reliability, Cronbach's alpha coefficient, psychometric inference, and inter-item covariance structure are made between the…

A study examined how many and what kind of questions appear in elementary science and social studies textbooks and teachers' manuals. Approximately 7500 questions from fourth and fifth grade science and social science textbooks from three major publishers were classified according to the following characteristics: (1) type of cognitive demand; (2)…

In a study of memory use in language comprehension, 84 second grade, 54 sixth grade, and 54 college students produced elaborations on sentences. In a context elaboration, task students put sentences in different contexts, and, in a causal inferencing task, they inferred alternative reasons for events. Language understanding was measured by the…

The use of computers to build diagnostic inferences is explored in two contexts. In computerized monitoring of liquid oxygen systems for the space shuttle, diagnoses are exact because they can be derived within a world which is closed. In computerized classroom testing of reading comprehension, programs deliver a constrained form of adaptive…

Teachers' knowledge and understanding of classrooms is perceived in this study in terms of interpretation of non-verbal and situational cues. Two sets of videotapes of classroom episodes were prepared, one in Hebrew and one in Dutch. These tapes were viewed by Israeli and Dutch teachers in cross-cultural settings. Teachers responded in writing and…

Working on the assumption that story structure contributes to the reading comprehension of students, a study assessed the comprehension and recall of 12 seventh and eighth grade remedial reading students. Subjects read a basal story revised to conform to a familiar story grammar and the original, unrevised, basal story. The two original stories…
