We examined dynamic assessment's (DA's) added value over traditional assessments for identifying Spanish-speaking English learners' (ELs) risk for developing mathematics disabilities, as a function of the language of test administration (English vs. Spanish), type of math outcome, and EL's language dominance. At the start of first grade, ELs (N =…

We examined dynamic assessment's (DA's) added value over traditional assessments for identifying Spanish-speaking English learners' (ELs') risk for developing mathematics disabilities, as a function of the language of test administration (English vs. Spanish), type of math outcome, and EL's language dominance. At the start of 1st grade, ELs (N =…

The purpose of this study was to assess the added value of dynamic assessment (DA) beyond more conventional static measures for predicting individual differences in year-end 1st-grade calculation (CA) and word-problem (WP) performance, as a function of limited English proficiency (LEP) status. At the start of 1st grade, students (129 LEP; 163…

The purpose of this study was threefold: to examine unique and shared risk factors of comorbidity for reading comprehension and word-problem solving difficulties, to explore whether language minority (LM) learners are at increased risk of what we refer to as "higher order comorbidity" (reading comprehension and word-problem solving…

Presenting major advances in understanding learning disabilities (LDs) and describing effective educational practices, this authoritative volume has been significantly revised and expanded with more than 70% new material. Foremost LD experts identify effective principles of assessment and instruction within the framework of multi-tiered systems of…

The purpose of this study was to assess the value of dynamic assessment (DA; degree of scaffolding required to learn unfamiliar mathematics content) for predicting 1st-grade calculations (CAs) and word problems (WPs) development, while controlling for the role of traditional assessments. Among 184 1st graders, predictors (DA, Quantity…

During the past decade, responsiveness to intervention (RTI) has become popular among many practitioners as a means of transforming schooling into a multilevel prevention system. Popularity aside, its successful implementation requires ambitious intent, a comprehensive structure, and coordinated service delivery. An effective RTI also depends on…

Progress monitoring focuses on individualized decision making in general and special education with respect to academic skill development at the elementary grades. Progress monitoring is conducted frequently (at least monthly) and is designed to: (1) Estimate rates of improvement; (2) Identify students who are not demonstrating adequate progress…

The purpose of the present study was to explore the 3rd-grade cognitive predictors of 5th-grade computational skill with rational numbers and how those are similar to and different from the cognitive predictors of whole-number computational skill. Students (n=688) were assessed on incoming whole-number calculation skill, language, nonverbal…

With the last reauthorization of the Individuals With Disabilities Education Act (IDEA) and the Elementary and Secondary Education Act (ESEA, also known as No Child Left Behind or NCLB), special education research exerted a major influence on general education. Even so, the academic outcomes of students with learning disabilities (LD), who are the…

The authors report on a mixed-methods review of 24 studies that explores the predictive validity of dynamic assessment (DA). For 15 of the studies, they conducted quantitative analyses using Pearson's correlation coefficients. They descriptively examined the remaining studies to determine if their results were consistent with findings from the…

Formative evaluation focuses on program modification based on ongoing measurement of student progress. The literature on formative evaluation for mildly handicapped students indicates that four measurement dimensions are critical: (1) focus of measurement; (2) frequency of measurement; (3) data display; and (4) data utilization methods. (Author/CB)

A data-based approach is introduced as an alternative way to help teachers formulate decisions about the validity of test accommodations for students with learning disabilities. Three rationales for the approach are provided: an inadequate research base to guide decision-making, student heterogeneity, and problems with teacher's use of subjective…

This digest summarizes principles of performance assessment, which connects classroom assessment to learning. Specific ways that assessment can enhance instruction are outlined, as are criteria that assessments should meet in order to inform instructional decisions. Performance assessment is compared to behavioral assessment, mastery learning, and…

Curriculum-based measurement (CBM) is defined and described through a case study of a fourth-grade student. CBM is suggested as a system for monitoring goal appropriateness, adjusting instructional programs, and formulating instructional improvements. Potential contributions of CBM to special education practice are outlined, and areas of needed…
