1 Parents vs. TV L. Quentin Dixon Harvard Graduate School of Education

2 Parents vs. TV The Relative Importance of Caregiver Language versus TV Language in Predicting English Vocabulary Skills among Bilingual Kindergarten Children in Singapore

3 Todays Presentation Why Singapore? Previous Research Research Questions Methods Results Discussion

4 Why Singapore?

5 Why Singapore? 3 major ethnic groups: 77% Chinese 14% Malay 8% Indian 4 official languages: Mandarin, Malay, Tamil, & English Most families are not native-English speakers English is the medium of education Mother Tongue is a required subject

6 Why Singapore?

7 Why Singapore? Third International Math and Science Study (TIMSS) 1995 Third International Math and Science Study-Repeat (TIMSS-R) 1999 Reading Literacy Study 1991 Progress in Reading Literacy Study (PIRLS) 2001

8 Previous Research: TV and L1 vocabulary L1 English-speaking children learned vocabulary presented through TV (Rice & Woodsmall, 1988) Viewing Sesame Street was correlated with vocabulary growth among L1 English- speaking children (Rice, Huston, Truglio, & Wright, 1990).

9 Previous Research: TV and L2 vocabulary Home TV viewing significantly predicted Spanish-English bilingual childrens receptive and expressive English vocabulary at the beginning and end of kindergarten in the US (Uchikoshi, 2004). Dutch children learned L2 vocabulary through viewing subtitled and unsubtitled English TV programs (Koolstra & Beentjes, 1999)

10 Previous Research: TV and L2 vocabulary Frequency of TV viewing did not significantly predict English vocabulary of bilingual 2-year- old children in the US (Patterson, 2002)

11 Research Question What is the role of caretaker language, TV language and mother tongue vocabulary in predicting English vocabulary of kindergarten pupils in Singapore?

12 Stratified Random Sample of Kindergarten Centers by Region 28 centers participated

13 Within Center, Stratified Random Sample of Children by Ethnicity n = 285 59% Chinese 22% Malay 18% Indian

14 Sample by Home Language Language categoryPercentage (n = 285) English only16% English and Other27% Other Language Only 56%

15 Predictors Home Background Questionnaire Caretaker language TV language Peabody Picture Vocabulary Test-III Translated into Mandarin, Malay & Tamil

16 Outcome Measures Peabody Picture Vocabulary Test III (PPVT-III) in English

17 Control Variables Home Background Questionnaire Mothers education Family income Ethnicity Gender

18 Data Collection Procedures

19 6 local bilingual Research Assistants administered tests Fluent Mandarin, Malay, & Tamil speakers Trained to administer child assessments All data were collected within a 3-week period in July, 2003

22 Results: Caretaker Language

23 Results: TV Language

24 Discussion Supports studies that indicate children can learn vocabulary from TV (Uchikoshi, 2004; Koolstra & Beentjes, 1999; Rice, Huston, Truglio, & Wright, 1990; Rice & Woodsmall, 1988)

25 Discussion Seems to contradict the finding that number of hours of TV viewing did not significantly predict bilingual childrens English vocabulary (Patterson, 2002) BUT Number of hours of TV viewing was not significant

26 Limitations Correlational Parental report data
