IV: RESULTS FOR STUDIES 2 AND 3: THE UKBTAT MODEL AND ITS APPLICATION TO NONTARGET ADDITIONAL LANGUAGE LEARNERS.

Abstract

The aim of Study 2 was to develop the UKBTAT (UK Bilingual Toddlers Assessment Tool), the first screening tool for assessing the vocabulary size of bilingual 2-year-olds, in this case learning British English and one of the 13 target Additional Language. The aim of Study 3 was to establish the reliability of UKBTAT for bilingual children learning British English and any other non-target Additional Language. Norms for bilingual vocabulary in English were obtained through regression equations in linear mixed models, using variables shown to be predictive of comprehension and production in the previous analyses (Chapter 3). Similarly, norms for the Additional Language vocabulary were calculated for children learning one of the 12 target Additional Languages (Spanish is sadly absent from the final list of target languages due to some disagreement with the Spanish CDI editors, TEA Ediciones).
