4. 4 Mirjam Trapman, EARLI 2009 Individual attributes Research questions What are the literacy-related individual variables associated with reading comprehension of both monolingual and bilingual at-risk adolescents? What is the role of low order literacy skills in reading comprehension of at-risk adolescents?

5. 5 Mirjam Trapman, EARLI 2009 Decoding skills and reading comprehension Role of decoding skills diminishes over time –Correlations between both skills is higher for beginning readers than for older children (a.o. Aarnoutse & Van Leeuwe 1988) –Role of higher order skills increases Hypotheses for our population – two possibilities 1. There is no correlation – after elementary school 2. There is a correlation – participants lag behind Hypotheses tested for two groups of participants Monolingual and bilingual at-risk adolescents

6. 6 Mirjam Trapman, EARLI 2009 Sample Lower tracks of prevocational secondary education (vmbo): basic and middle management program 30% lowest end of CITO End of Primary School Test Grade 7 N = 63 Monolingual (N = 32) and bilingual students (N = 31) –Maroccan (n = 10), Turkish (n = 9), Antillean (n = 4), Surinamese (n = 4), Capeverdian (n = 3), Chinese (n = 1)

14. 14 Mirjam Trapman, EARLI 2009 Total amount of explained variance - 48% for the monolingual group - 72% for the bilingual group Role of grammar significant contribution for the bilingual group, but not for the monolingal group, once decoding skill is in the model already Role of decoding skills significant contribution for the monolingual group, but not for the bilingual group Difference between monolinguals and bilinguals

15. 15 Mirjam Trapman, EARLI 2009 What are the literacy-related individual variables associated with reading comprehension of both monolingual and bilingual at-risk adolescents? Monolinguals: decoding skills Bilinguals: grammar What is the role of low-order literacy skills in reading comprehension of at-risk adolescents? Monolinguals: significant contribution Bilinguals: no significant contribution Back to the questions

16. 16 Mirjam Trapman, EARLI 2009 Discussion Possible explanation role vocabulary and grammar? difference in performance between groups? Near future analyses
