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…

Abedi, Jamal; Leon, Seth; Kao, Jenny C. – National Center for Research on Evaluation, Standards, and Student Testing (CRESST), 2008
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…

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…
