Users of educational hypertext are faced with the challenge of creating meaning both within and between texts. Cohesion is an important factor contributing to whether a reader is able to capture meaning and comprehend text. When readers are required to fill in conceptual gaps in text, comprehension can fail if they do not have sufficient…

This study explores the use of multiple measures to enhance the validity and reliability of inferences about school and district effectiveness. Using data from the state of Ohio, a framework for combining measures is applied to examine the individual and collective impact of multiple measures on both the federal AYP designations and state ratings.…

The evaluation of systematic review as part of the evidence-based or evidence-informed practice movement is a dominant theme in current debates in educational research. This article contributes to the debate by offering a personal, reflexive narrative on the process of doing systematic review, relating some of the arguments regarding the merits…

Many statistics educators believe that few students develop the level of conceptual understanding essential for them to apply correctly the statistical techniques at their disposal and to interpret their outcomes appropriately. It is also commonly believed that the sampling distribution plays an important role in developing this understanding.…

Colleagues in the field of mental health have made considerable progress developing inventories of evidence-based practice; however, the field of special education for children with emotional or behavioral disorders has only recently begun to do so. This paper provides some personal reflections on four major issues for consideration as we pursue…

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…

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…
