The diagnosis of developmental dyslexia (DD) is reliant on a discrepancy between intellectual functioning and reading achievement. Discrepancy-based formulae have frequently been employed to establish the significance of the difference between "intelligence" and "actual" reading achievement. These formulae, however, often fail to take into…

Specialists in the field of large-scale, high-stakes writing assessment have, over the last forty years alternately discussed the issue of maximizing either reliability or validity in test design. Factors complicating the debate--such as Messick's (1989) expanded definition of validity, and the ethical implications of testing--are explored. An…

This paper focuses on two key aspects of self-evaluation in adult education and training through the perspective of (a) a social-cognitive framework which is used to categorise those factors that enhance self-efficacy and self-evaluation, and (b) the accuracy of self-evaluation. The social-cognitive framework categorises the factors that enhance…

Empathy has been suggested to facilitate effective collaborative problem solving in children. The current study adapted the Interpersonal Reactivity Index (IRI, Davis, 1980), a well-validated empathy measure for adults, for use with children aged 8 and 9 years. Four hundred and thirteen school children aged between 7;11 and 9;11 years completed…

Each year for the past 25 years, the Center for Gifted Education at the University of Arkansas at Little Rock conducts a three-week summer enrichment program for gifted and talented students entitled Summer Laureate/University for Youth. The program was developed to provide a practicum experience for teachers seeking either licensure or a master's…

Single equation regression models have been used rather extensively to test the effectiveness of Supplemental Instruction (SI). This approach, however, fails to account for the possibility that SI attendance and the outcome of SI attendance are jointly determined endogenous variables. Moreover, the standard approach fails to account for the fact…

States are establishing high stakes assessments to serve as a measurement tool of students' academic abilities. This study essentially explored and sought to understand some of Maryland's mathematics and science practitioners' perspectives on increase testing, and the No Child left Behind (NCLB) Act. Basically, the study sought to understand and…

This study aimed at finding out the effects of Mastery Learning Approach (MLA) on students' achievement in Physics. The study was Quasi-experimental and Solomon Four Non-equivalent Control Group Design was used. The target population comprised of secondary school students in Kieni East Division of Nyeri District. The accessible population was Form…

Psychological methods of assessing intelligence have been criticised because of their limited diagnostic-remedial nature and especially their lack of potential for initiating effective and pragmatic intervention programmes. Similarly, the means through which the results of such methods are communicated in order to make them useful and constructive…

The purpose of the study was to determine comparability of an online version to the original paper-pencil version of Defining Issues Test 2 (DIT2). This study employed methods from both Classical Test Theory (CTT) and Item Response Theory (IRT). Findings from CTT analyses supported the reliability and discriminant validity of both versions.…

This paper introduces an evaluation tool prepared to examine the quality of visuals in course-books. The tool is based on Mayer's Cognitive Theory of Multimedia Learning (i.e. Generative Theory) and its principles regarding the correct use of illustrations within text. The reason to generate the tool, the development process along with the…

A principal components analysis of the Teacher Rating Scale-Child (TRS-C) of the Behavior Assessment System for Children was conducted with a cross-sectional cohort of 659 children in Grades 1 to 5. A predictive validity study was then conducted with a 2-year longitudinal sample of 206 children. The results suggested that scores from the resulting…

The study developed a Big 6 Information Problem-Solving Scale (B61PS), including the subscales of task definition and information-seeking strategies, information access and synthesis, and evaluation. More than 1,500 fifth and sixth graders in Taiwan responded. The study revealed that the scale showed adequate reliability in assessing the…

Children with developmental disorders may present with listening and/or speech discrimination difficulties. This study explores whether teachers can identify these difficulties, using a questionnaire that rates children's listening, speech discrimination and comprehension abilities. The questionnaire was given to class-teachers of 52 pupils, aged…

Web-based courses are promising in that they are effective and have the possibility of their instructional design being improved over time. However, the assessments of said courses are criticized in terms of their validity. This paper is an exploratory case study regarding the validity of the assessment system used in a semi presential web-based…
