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…

Abedi, Jamal; Zhang, Yu; Rowe, Susan E.; Lee, Hansol – Educational Measurement: Issues and Practice, 2020
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 incorrect response choices, or distractors, by students with disabilities in standardized reading assessments. Differential distractor functioning (DDF) analysis differs from differential item functioning (DIF) analysis, which treats all answers alike and examines all wrong answers against the correct answer. DDF analysis…

O'Conner, Rosemarie; Abedi, Jamal; Tung, Stephanie – Regional Educational Laboratory Mid-Atlantic, 2012
This study describes English language learner (ELL) student enrollment and achievement trends in Delaware public schools from 2002/03 to 2008/09. Two research questions guide this study: (1) How did the enrollment of ELL students in Delaware public schools change between 2002/03 and 2008/09?; and (2) How did performance (the percentage scoring at…

Abedi, Jamal; Leon, Seth; Kao, Jenny C. – National Center for Research on Evaluation, Standards, and Student Testing (CRESST), 2008
This study examines performance differences between students with disabilities and students without disabilities students using differential item functioning (DIF) analyses in a high-stakes reading assessment. Results indicated that for Grade 9, many items exhibited DIF. Items that exhibited DIF were more likely to be located in the second half…

Herman, Joan L.; Abedi, Jamal – US Department of Education, 2004
The Annual Yearly Progress (AYP) requirements of No Child Left Behind (NCLB) underscore both the mandate and the challenge of assuring that English Language Learners (ELLs) achieve the same high standards of performance that are expected of their native English speaking peers. The intent indeed is laudable: states, districts, schools, and teachers…
