Page 5: Parents vs. TV L. Quentin Dixon Harvard Graduate School of Education.

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

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).

Page 9: Parents vs. TV L. Quentin Dixon Harvard Graduate School of Education.

Previous Research: TV and L2 vocabulary Home TV viewing significantly predicted

Spanish-English bilingual children’s 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)

Page 10: Parents vs. TV L. Quentin Dixon Harvard Graduate School of Education.

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)

Page 11: Parents vs. TV L. Quentin Dixon Harvard Graduate School of Education.

Research Question What is the role of caretaker

language, TV language and mother tongue vocabulary in predicting English vocabulary of kindergarten pupils in Singapore?

Discussion Supports studies that indicate

children can learn vocabulary from TV (Uchikoshi, 2004; Koolstra & Beentjes, 1999; Rice, Huston, Truglio, & Wright, 1990; Rice & Woodsmall, 1988)

Page 25: Parents vs. TV L. Quentin Dixon Harvard Graduate School of Education.

Discussion

Seems to contradict the finding that number of hours of TV viewing did not significantly predict bilingual children’s English vocabulary (Patterson, 2002)

BUTNumber of hours of TV viewing was not significant
