Calculating and reporting appropriate measures of effect size are becoming standard practice in psychological research. One of the most common scenarios encountered involves the comparison of 2 groups, which includes research designs that are experimental (e.g., random assignment to treatment vs. placebo conditions) and nonexperimental (e.g.,…

Single-case experimental designs (SCEDs) provide a time- and cost-effective alternative to randomized clinical trials and offer significant advantages in terms of internal and external validity. A brief history and primer on SCEDs is provided, specifically for use in suicide intervention research. Various SCED methodologies, such as AB, ABAB,…

The traditional kappa statistic in assessing interrater agreement is not adequate when multiraters and multiattributes are involved. In this article, latent trait models are proposed to assess the multirater multiattribute (MRMA) agreement. Data from the Third International Mathematics and Science Studies (TIMSS) are used to illustrate the…

Through contributions from top leaders in Autism Spectrum Disorder (ASD), "Children and Youth with Autism Spectrum Disorder" examines the ASD research literature, discusses procedural implications, and makes recommendations for future practice and inquiry. It combines the most recent developments in established practices with newer and…

The Adult Literacy Research Working Group (ALRWG), a panel of experts on adult reading research and practice, was established by the National Institute for Literacy (NIFL) in collaboration with the National Center for the Study of Adult Learning and Literacy (NCSALL). It was part of the Institute's efforts to provide educators, parents and others…

This popular practitioner guide and text presents an effective, problem-solving-based approach to evaluating and remediating academic skills problems. Leading authority Edward S. Shapiro provides practical strategies for working with students across all grade levels (K-12) who are struggling with reading, spelling, written language, or math.…

This paper reviews what has been learned about evaluation ultilization during the past 20 years. Evaluation utilization is discussed in terms of what is used, who uses evaluation, when evaluation is used, how evaluation is used, where evaluation is used, and why evaluation is used. It is suggested that the personal factor - the interests and…

The purpose of this Guide is to advise researchers, policymakers, and others on when it is possible to conduct a high-quality randomized controlled trial in education at reduced cost. Well-designed randomized controlled trials are recognized as the gold standard for evaluating the effectiveness of an intervention (i.e., program or practice) in…

Essay tests are widely used to assess ESL/EFL learners' writing abilities for instructional, administrative, and research purposes. Relevant literature was searched to identify 70 empirical studies on ESL/EFL essay tests. The majority of these studies examined task, essay, and rater effects on essay rating and scores. Less attention has been given…

Introduction: Advising in Educational Psychology from the perspective of RDI takes on a stronger investigative, innovative nature. The model proposed by De la Fuente et al (2006, 2007) and Education & Psychology (2007) was applied to the field of improving teaching-learning processes at a school. Hypotheses were as follows: (1) interdependence…

By common consent there is a "gold standard" in reference to which the efficacy of medical interventions needs to be evaluated. It is suggested in this paper that in educational research achievement of this gold standard is rarely possible. It does not follow, however, that research that falls short of this standard is therefore valueless; there…

The mere fact that a library service is being used does not mean that the service makes a difference or has a positive impact on the user. This has significant implications for Special Library and Information Services (SL&IS) that have to constantly prove that they add value. Because of the difficulty of measuring impact effectively, the…

The chapters in this book reflect the work of science and mathematics educators who have worked for many years at the international level. As members of the International Consortium for Research in Science and Mathematics Education, their work provides readers with issues, models, practices, and research results that have applicability and…

The technical complexities and sheer size of international large-scale assessment (LSA) databases often cause hesitation on the part of the applied researcher interested in analyzing them. Further, inappropriate choice or application of statistical methods is a common problem in applied research using these databases. This article serves as a…

This article discusses the first stages of the work of the Teacher Education Group (TEG) in building research capacity in teacher education research and identifies the potential of the model adopted for future European initiatives in the field. The TEG work is part of the second phase of the Teaching and Learning Research Programme (TLRP), based…
