520    The purpose of this study was to compare how English 
       language learners (ELLs) and monolingual English speakers 
       solved multiple-choice items administered with and without
       a new form of testing accommodation---vignette 
       illustration (VI). By incorporating theories from second 
       language acquisition, bilingualism, and sociolinguistics, 
       this study was able to gain more accurate and 
       comprehensive input into the ways students interacted with
       items. This mixed methods study used verbal protocols to 
       elicit the thinking processes of thirty-six native Spanish
       -speaking English language learners (ELLs), and 36 native-
       English speaking non-ELLs when solving multiple-choice 
       science items 
520    Results from both qualitative and quantitative analyses 
       show that ELLs used a wider variety of actions oriented to
       making sense of the items than non-ELLs. In contrast, non-
       ELLs used more problem solving strategies than ELLs. There
       were no statistically significant differences in student 
       performance based on the interaction of presence of 
       illustration and linguistic status or the main effect of 
       presence of illustration. However, there were significant 
       differences based on the main effect of linguistic status.
       An interaction between the characteristics of the students,
       the items, and the illustrations indicates considerable 
       heterogeneity in the ways in which students from both 
       linguistic groups think about and respond to science test 
       items 
520    The results of this study speak to the need for more 
       research involving ELLs in the process of test development
       to create test items that do not require ELLs to carry out
       significantly more actions to make sense of the item than 
       monolingual students
