pop-up glossary, English dictionary, extra testing time, and small-group testing
Students in grades 4 and 8 from a single school district in Southern California
Four accommodation conditions were tested computer accommodation with a pop-up English glossary, a customized English dictionary, extra time, and small-group testing. Computer administration with a glossary and extended time showed statistically significant effects accounting for 3.0 and 2.4 percent of the variance in math scores respectively. These accommodations did not affect the results of non-EL students, reducing potential accommodations related validity concerns. A customized English dictionary did not show a statistically significant effect and the small group testing accommodation lacked the sample size (power) to assess its potential effects.
