Speech-language pathologists (SLPs) are experiencing the exciting challenge of serving increasing numbers of English Language Learners (ELLs) in U.S. schools. When ELLs struggle in school, they may be overreferred for speech-language services. SLPs are routinely expected to differentiate a language difference based on cultural, linguistic, and…

Purpose: Children with specific language impairment (SLI) demonstrate significant language impairments despite normal-range hearing and nonverbal IQ. Many of these children also show marked deficits in working memory (WM) abilities. However, the theoretical and clinical characterization of the association between WM and language limitations in SLI…

Background: The relation between academic self-concept and achievement has been examined in a large number of studies. The majority of these studies have found evidence for a reciprocal effects model. However, there is an ongoing debate on how students' achievement should be measured and whether the type of achievement indicator (grades, tests,…

Given the implementation of the No Child Left Behind (NCLB) Act, one might reasonably assume that the research literature on the effects of standardized testing would have been exposed, made widely familiar, and meticulously analyzed in the early 2000s. But just the opposite happened. As belief in the research literature's nonexistence has spread,…

In the United States as well as in much of the developed world, many of us tend to take for granted that children who do well on teacher-made and standardized tests are intelligent. But different cultures have different views of intelligence, so which children are considered intelligent may vary from one culture to another. Moreover, the acts that…

This article illustrates the use of an explanatory item response modeling (EIRM) approach in the context of measuring group differences in science achievement. The distinction between item response models and EIRMs, recently elaborated by De Boeck and Wilson (2004), is presented within the statistical framework of generalized linear mixed models.…

Value-added models help to evaluate the knowledge that school districts, schools, and teachers add to student learning as students progress through school. In this article, the well-known Education Value-Added Assessment System (EVAAS) is examined. The author presents a practical investigation of the methodological issues associated with the…

To examine the reasons for declining Scholastic Aptitude Test scores during the past two decades, this paper proposes an empirical achievement model incorporating students' demographic characteristics and an expanding test-taking population. While test scores and participation rates are positively correlated, participation changes over time mask…

Evaluation of 252 children with specific language impairments found varying degrees of congruence between clinically identified children and those identified using discrepancy, deficit, and standardized operational criteria. Results suggest that the global concept of a "specific language impairment" may not be a useful concept for either…

Some of the most pervasive educational innovations are occurring within teacher-education curricula at historically Black institutions. Although these institutions represent only 5 percent of U.S. univerities and colleges, they have produced 66 percent of the Black teachers. Data concerning historically Black and White state colleges in Maryland…

Examines practices that encourage false negatives and false positives on licensing and certification tests designed to protect the public. Recommends increasing the amount of testing or raising the required passing score for repeat test takers. (FMW)

This study analyzed the factor structure of the Woodcock Reading Mastery Tests Revised (WRMT-R), a test battery used to measure basic reading skills. Findings indicated that both forms of the WRMT-R contain a large unrotated general factor and, when rotated obliquely, two correlated factors representing basic skills and reading comprehension.…

This paper presents tables for converting raw scores on the Bayley Scales of Infant Development to Mental Development Index and Psychomotor Development Index values. The tables were developed to generate index values for young children with developmental delays, based on recent revision of the scales and standardization procedures. Methodology is…

Reading and math achievement subtest scores on several standard achievement tests were compared for 233 students with mental retardation. Correlations were generally moderate among subtests purporting to measure similar constructs. Significant mean differences were present for five of seven reading test comparisons and for six of eight math…

Two cases are reported to illustrate the ways in which standardized tests fail blind children. Other assessment devices are recommended to allow a child to demonstrate how he or she makes sense of the world, such as observational techniques, interviews, structured teaching, exploration, and play.
