The purpose of this study was to apply a random item mixture nominal item response model (RIM-MixNRM) for investigating instruction effects. The host study design was a pre-test-and-post-test, school-based cluster randomized trial. A RIM-MixNRM was used to identify students' error patterns in mathematics at the pre-test and the post-test.…

Latent transition analysis (LTA) was initially developed to provide a means of measuring change in dynamic latent variables. In this article, we illustrate the use of a cognitive diagnostic model, the DINA model, as the measurement model in a LTA, thereby demonstrating a means of analyzing change in cognitive skills over time. An example is…

This study used a multiple probe across participants design to examine the effects of a model drawing strategy (MDS) intervention package on fraction comparing and ordering word problem-solving performance of three Grade 4 students. MDS is a form of cognitive strategy instruction for teaching word problem solving that includes explicit instruction…

A multilevel latent transition analysis (LTA) with a mixture IRT measurement model (MixIRTM) is described for investigating the effectiveness of an intervention. The addition of a MixIRTM to the multilevel LTA permits consideration of both potential heterogeneity in students' response to instructional intervention as well as a methodology for…

Response to intervention (RTI) is a new method of identifying students with learning disabilities. RTI's increasing implementation affects all teachers and students, in both general and special education. The authors provide educators with a practical understanding of what RTI may look like in the classroom and how co-teaching as an instructional…

Currently, learning disabilities (LD) are diagnosed on the basis of the discrepancy between students' IQ and reading achievement scores. Students diagnosed with LD often receive remedial instruction in resource rooms. The available evidence suggests that the educational policy based on this discrepancy model has not yielded satisfactory results.…

One validated model for teaching strategies to less skilled writers is the self-regulated strategy development (SRSD) approach. This method has been used to successfully improve the writing of children with learning disabilities and has recently been extended to students with emotional and behavioral disorders and attention-deficit/hyperactivity…

Response to Intervention (RTI) is an instructional framework through which schools can provide early intervention for students experiencing academic and behavioral difficulties. It is also promoted as an alternative to the IQ-discrepancy model for identifying students with learning disabilities. Most states have developed, or are developing,…

Response to intervention (RTI) is a framework for providing interventions and services at increasing levels of intensity until students succeed. The framework helps teachers and schools provide instruction and interventions matched to student needs, monitor progress frequently to guide decisions about changes in instruction or goals, and apply…

The Responsiveness to Intervention (RI) model for diagnosing learning disabilities has been proposed as an alternative to previous definitions. Given the importance of reliable and valid assessment in the instructional process, assessment must be a crucial aspect of any RI approach. Curriculum-based measurement (CBM) has been discussed in previous…

The use of demonstration plus permanent model (DPM) as a teaching strategy was evaluated with 19 learning disabled students (ages 9-14) in the area of computational skills. Results indicated that DPM effectively helped students acquire computational skills across instructional sequences for addition, subtraction, and multiplication. (Author/DB)

Reviews assistive technology as it relates to postsecondary students with learning disabilities by (1) tracing its development, (2) identifying models of assistive technology service delivery and specific services, (3) describing specific assistive technologies, and (4) reviewing research on the effectiveness of assistive technology with…

The article maintains that a reductionist fallacy in the four major models (medical, psychological, behavioral, and cognitive strategy) underlying services to learning disabled students explains the efficacy problems that have long plagued the field. (Author/DB)

This paper discusses the two important domains affecting the success of learning strategy training for students with learning disabilities or other mild handicaps: students' knowledge of critical skills and information potentially related to strategy use, and students' motivation to learn and use the strategy. The paper presents an eight-stage…

Children with attention deficit/hyperactivity disorder (ADHD) are at increased risk of academic difficulties and special education placement (Barkley, 1998). One academic area, written expression, has received little research attention. This study assessed the effectiveness of a validated strategy instruction model--Self-Regulated Strategy…
