This book "supplies a vocabulary of English words and idiomatic phrases 'arranged … according to the ideas which they express'. The thesaurus, continually expanded and updated, has always remained in print, but this reissued first edition shows the impressive breadth of Roget's own knowledge and interests."
The author examines the ways that specialized language development teachers assess the linguistic skills of preschool children for whom German is a second language. In a longitudinal study, she also investigates how accurately language development teachers are able to judge these skills. These multi-methodical studies contribute to the field of bilingual language education and language acquisition research.
