WWC Review of the Report "Accommodations for English Language Learner Students: The Effect of Linguistic Modification of Math Test Item Sets"
What Works Clearinghouse
The research described in this report is a randomized controlled trial in which seventh- and eighth-grade students were randomly assigned to complete a set of 25 math questions delivered with either standard language or language that had undergone "linguistic modification" by the research team. The purpose of the study was to assess the effects of using "linguistic modification" as a way of removing language barriers for English language learners and non-English language learners struggling with reading. Nearly 3,000 students from 13 middle schools in five school districts in California were randomly assigned to complete traditional math assessments or math assessments that had undergone "linguistic modification." Researchers then examined the results for three subgroups of students: Spanish-speaking English language learners (EL), non-English language learners who were not proficient in English language arts (NEP), and non-English language learners who were proficient in English language arts (EP). Comparisons were made between students who took the modified test and those who took the non-modified test. The study found a positive effect on math scores for students struggling with English who completed the "linguistic modification" item set relative to similar students who did not. The estimated six percentage-point gain on math achievement is statistically significant. The study found neither statistically significant nor substantively important differences for EP students who took the modified test, relative to those who did not. The research described in this report meets the What Works Clearinghouse (WWC) evidence standards without reservations. Appended are: (1) Study details; (2) Outcome measures for each domain; (3) Study findings for the mathematics achievement domain; and (4) Subgroup findings for the mathematics achievement domain. A glossary of terms is included. (Contains 6 tables and 5 endnotes.)
