Simulation studies use computer-generated data to examine questions of interest that have traditionally been used to study properties of statistics and estimating algorithms. With the recent advent of powerful processing capabilities in affordable computers along with readily usable software, it is now feasible to use a simulation study to aid in…

Even in primary school, mathematics achievement depends upon the efficiency of cognitive, metacognitive and self-regulatory processes. Thus, for pupils to carry out a computation, such as a written calculation, metacognitive mechanisms play a crucial role, since children must employ self-regulation to assess the precision of their own thinking and…

Ongoing research has demonstrated that culturally and linguistically diverse (CLD) students may be disproportionately represented among students with learning disabilities (LDs). The main aim of this research was to identify groups of CLD students at risk for LDs using the achievement criterion. To that end, 158 students participated in the…

An examination was conducted to address issues concerning the assessment of students with learning disabilities (LD) in English speaking Canadian postsecondary institutions. These issues concern the nature of appropriate and evidence-based assessment and whether there is fair access to academic accommodations for students with LD. Access to…

Psychoeducational assessment, and specifically cognitive testing, is important to the role of school psychologists; however, the utility of such testing has been called into question, and its future is unclear. Researchers are divided into two camps. One side grew disenchanted with cognitive testing after the failure of the discrepancy method to…

More than 20 years ago, psychologists first described gifted students with learning disabilities (LD). In the past decade, several sets of identification criteria have been proposed for this population. Many of the suggested assessment practices are unsupported by research in psychoeducational assessment, and some have been directly contradicted…

The Individuals With Disabilities Education Improvement Act of 2004 (IDEA; 2004) permitted lack of students' response to intervention (RTI) to be considered as a basis for documenting specific learning disabilities (SLD). The previous method of detecting SLD, which relied on IQ and achievement testing, consequently is no longer mandatory.…

Objective/Method: The Conner's Continuous Performance Test (CPT) was administered to four groups of adult college students who self-referred for comprehensive psychoeducational evaluation and received either no diagnosis (n = 30) or a diagnosis of ADHD (n = 26), a psychiatric disorder (n = 17), or various cognitive deficits (n = 22). Results: The…

The author reviews research which questions the worth of psychoeducational diagnosis of learning disabilities, and suggests a model that places the teacher as the primary decision maker in identification, diagnosis, and programing. Three concerns about psychoeducational diagnosis are raised: the conceptualization of learning disabilities as a…

An alternative to the IQ-achievement discrepancy model for identifying students with learning disabilities is the response to intervention (RTI) model. There is a growing literature base in support of the RTI model, and within the reauthorization of IDEA there is an allowance for an RTI approach whereby RTI "may" be used by school…

Questions concerning identifying and treating Attention-Deficit Hyperactivity Disorder (ADHD) are addressed, including whether ADHD is a handicapping condition, and what guidelines should be used for determining the need for educational services. A psychoeducational paradigm is presented to help school psychologists design effective programs for…

Intended for the student and teacher, primary source material is presented on theories and research relating to reading disability. Conflicting concepts of human development are discussed in the overview . Emotional neurophysiological, and cultural factors involved in causation are evaluated in 18 papers, diagnostic considerations in eight, and…

Written primarily for use by persons concerned with the establishment and operation of learning disability programs the text presents a rationale for programing, definitions, examples, and educational rationales for basic learning abilities, and a model school district policy statement. Preliminary screening, psychological evaluation, a…
