A popular theoretical account of developmental language and literacy disorders implicates poor auditory temporal processing in their etiology, but evidence from studies using behavioral measures has yielded inconsistent results. The mismatch negativity (MMN) component of the auditory event-related potential has been recommended as an alternative,…

This article addresses the perennial issue of the criteria by which qualitative research should be evaluated. At the present time, there is a sharp conflict between demands for explicit criteria, for example in order to serve systematic reviewing and evidence-based practice, and arguments on the part of some qualitative researchers that such…

This article reviews the processes, issues and dilemmas involved in evaluation research undertaken in the context of changing and evolving government policy in education. The article is grounded in an evaluation of the National Partnership Project (NPP), the team conducted on behalf of England's Teacher Training Agency (TTA) in 2004-2005. It will…

This study examined the impact of rater agreement on decisions concerning the alignment between the "Golden State Examination in High School Mathematics" (California Department of Education, 2001a) and the University of California (UC) "Statement on Competencies in Mathematics Expected of Entering College Students" (Academic…

Applying Bloch's law to visual word recognition research, both exposure duration of the prime and its luminance determine the prime's overall energy, and consequently determine the size of the priming effect. Nevertheless, experimenters using fast-priming paradigms traditionally focus only on the SOA between prime and target to reflect the…

A substantial number of published articles in speech communication research today is experimental/social scientific in nature. It is only in the past decade that scholars have begun to put the history of communication under the lens. Early advocates of the adoption of the method of social scientific inquiry were J. A. Winans, J. M. O'Neill, and C.…

The visual image is so information-rich that describing its content fully can be very problematic. Trying to codify or analyze the content in any systematic way often proves even more difficult. Nevertheless, reducing certain aspects of visual data to a set of numbers can be useful because it exposes characteristics of the message that might be…

Applied psychologists who provide services to nations composed of multiple and widely varied cultural groups face certain ethical dilemmas that would not arise in more homogeneous societies. These ethical dilemmas revolve around the concept of population generalizability, which refers to the applicability of research findings across different…

Problems inherent in relying solely on statistical significance testing as a means of data interpretation are reviewed. The biggest problem with statistical significance testing is that researchers have used the results of this testing to ascribe importance or meaning to their studies where such meaning often does not exist. Often researchers…

This document results from a seminar held to initiate a dialogue on the ways and means of strengthening research capacity in developing countries. The seminar participants hoped to take stock of the economic and social changes that nations around the world have witnessed in this decade. These changes have engendered shifts in educational research…

To assess young children's understanding of false belief, investigators often show them a familiar container, then demonstrate that it holds an object different from the one the children expected. The children are then asked what they originally thought the container held, and what another container will hold. Three-year-old children typically…

Research results should not be taken at face value; some research is not well designed, and readers must be able to assess whether the research carried out actually supports the results or may be explained otherwise. Research reports are usually divided into introduction or literature review, methods, results, and discussion and conclusions. Basic…

The effects of various discourse variables on the psycholinguistic processing of sentences within paragraphs by 36 competent adult readers were investigated. Eye movement measures were used as the dependent variables reflecting psycholinguistic processing. When all of the constraints within which the study had to be performed were examined, it…

A quantitative method, meta-analysis, is used to integrate research findings from a representative group of 38 coaching studies. Because different studies reported results on different scales, effect size was used to transform all results to a common metric. This meta-analysis showed that there are two distinct literatures on the effectiveness of…
