Implementing a randomized controlled trial design, the present study investigated the effects of two types of accommodations, linguistic modification and a glossary, for English learners (ELs) taking a computer-based mathematics assessment. Process data including response time and clicks on glossary words were also examined to better interpret…

Research indicates that the performance-gap between English Language Learners (ELLs) and their non-ELL peers is partly due to ELLs' difficulty in understanding assessment language. Accommodations have been shown to narrow this performance-gap, but many accommodations studies have not used a randomized design and are based on relatively small…

This study examines the power of cognitive and noncognitive variables to predict students' performance in algebra. We investigated students' prior year's assessment scores and demographic characteristics to predict eighth-grade algebra scores. Using California statewide assessment data, we explored predictive factors in three regression models.…

This study compared performance of both English language learners (ELLs) and non-ELL students in Grades 4 and 8 under accommodated and nonaccommodated testing conditions. The accommodations used in this study included a computerized administration of a math test with a pop-up glossary, a customized English dictionary, extra testing time, and…

Documents the findings of an experiment in which 12th-grade students taking a mathematics assessment were given monetary incentives to see whether such incentives would improve their performance. The study did not find that incentive increases performance. (Author/SLD)

In 1998 it became apparent that support for state assessments in Spanish at the elementary level was waning in Colorado, and it was likely that only an English-language version would be available for the grade 5 mathematics assessment in 1999. A study was conducted to provide empirical results to inform decisions regarding language accommodations…

Studied the importance of language in student test performance on mathematics word problems using items from the National Assessment of Educational Progress mathematics assessment. Results for 1,174 eighth graders show that students who were English language learners scored lower on the math test than proficient English speakers and that…

This study examines the linguistic features of the National Assessment of Educational Progress (NAEP) mathematics test items and investigates the significance of language-related variables for NAEP's assessment in the content area of mathematics. The continuing increase in the number of language minority students in classrooms nationwide has…

This study investigated the dimensionality of mathematics subscale scores from the National Assessment of Educational Progress for the assessment's Technical Review Panel, specifically for the data from the 1990 and 1992 main assessment in relation to students' instructional and noninstructional background variables. Discriminant analysis was…

This study compared the performance of English language learners and native speakers of English on mathematics word problems from the National Assessment of Educational Progress (NAEP) tests and investigated whether modifying the linguistic structures in the test items affected student test performance. The study began with the analysis of…

This study examined the impact of students' background characteristics (English language proficiency) on the level of effectiveness of various types of testing accommodations. Data were collected from 946 eighth graders, some of whom were English language learners. Four accommodation strategies were used: (1) modified (simplified) English language…

This publication reports the results of a research study on the feasibility and validity of various accommodations in the context of mathematics assessment. The study compared limited English proficiency (LEP) and non-LEP students' scores on 20 science items under three different conditions: standard National Assessment for Educational Progress…

Different forms of accommodation have been suggested in the assessment of English language learners (ELL). This study examined the effectiveness of a few accommodation strategies on the performance of ELL students in mathematics. A group of 946 eighth graders participated in this study. Using mathematics test items from the National Assessment of…

The impact of testing accommodation on the performance of students with limited English proficiency (LEP) was studied, focusing on the possibility of differential impact of accommodation strategies on subgroups formed based on students' background characteristics and the validity of assessments using accommodated versus nonaccommodated…
