Aim: Mutations in the "SLC16A2" gene have been implicated in Allan-Herndon-Dudley syndrome (AHDS), an X-linked learning disability syndrome associated with thyroid function test (TFT) abnormalities. Delayed myelination is a non-specific finding in individuals with learning disability whose genetic basis is often uncertain. The aim of this study…

Purpose: The mean length of children's utterances is a valuable estimate of their early language acquisition. The available normative data lack documentation of language and nonverbal intelligence levels of the samples. This study reports age-referenced mean length of utterance (MLU) data from children with specific language impairment (SLI) and…

This paper addresses the issue of how we might be able to assess productive vocabulary size in second language learners. It discusses some previous attempts to develop measures of this sort, and argues that a fresh approach is needed in order to overcome some persistent problems that dog research in this area. The paper argues that there might be…

This study compared oral personal and fictional narratives of diverse (African American and Caucasian) students with and without learning disabilities. Naturalistic conversation with embedded narrative prompts and supports provided the context for narrative elicitation. The participants were 82 fourth to seventh graders from urban and suburban…

Productive knowledge work and high-level literacy are essential for engagement in a Knowledge society. In the research reported in this article, students were engaged in sustained collaborative knowledge building in science and social studies. The vocabulary growth of 22 students over Grades 3 and 4 was traced, based on their entries to Knowledge…

A broad array of research findings suggest that older adults, as compared with younger adults, have a more positive sense of self and possibly a clearer and more consistent sense of self. Further, older adults report lower motivation to construct or maintain a sense of self. In the present study, we examined whether such differences in self-views…

The normalized gain, "g", has been an important tool for the characterization of conceptual improvement in physics courses since its use in Hake's extensive study on conceptual learning in introductory physics. The normalized gain is calculated from the score on a pre-test administered before instruction and a post-test administered…

Service supervision has become a central feature of the training of child psychotherapists in the UK. This paper reports on the work of a research workshop set up to explore the task and its complexities. The paper draws on several years of monthly meetings of a highly experienced group of supervisors. It discusses the methodology for studying…

An assessment with the Environment Rating Scales (ERS) is designed to give early childhood administrators and teaching staff much more than a set of quality scores. Appropriately used, an ERS assessment can provide a blueprint for planning and carrying out both immediate and long-range program improvements. Unfortunately, programs often complete…

In order to evaluate student learning achievement, several aspects should be considered, such as exercises, examinations, and observations. Traditionally, such an evaluation calculates a final score using a weighted average method after awarding numerical scores, and then determines a grade according to a set of established crisp criteria.…

Atypical attention, while not a diagnostic feature, is common in individuals with autism spectrum disorders (ASD). The study of these atypicalities has recently gained in both quantity and quality, due in part to an increased focus on attentional atypicalities as one of the earliest signs of ASD in infancy. A range of attentional processes and…

The study examines the professional development of junior-high-school teachers participating in the Israeli "Katom" (Computer for Every Class, Student and Teacher) Program, begun in 2004. A three-circle support and training model was developed for teachers' professional development. The first circle applies to all teachers in the…

Data of item responses to the Impossible Figures Task (IFT) from 492 Chinese primary, secondary, and university students were analyzed using the dichotomous Rasch measurement model. Item difficulty estimates and person ability estimates located on the same logit scale revealed that the pooled sample of Chinese students, who were relatively highly…

E-learning has become an increasingly important teaching and learning mode in educational institutions and corporate training. The evaluation of E-learning, however, is essential for the quality assurance of E-learning courses. This paper constructs a three-phase evaluation model for E-learning courses, which includes development, process, and…
