We meta-analyzed the effectiveness of incidental second language word learning from spoken input. Our sample contained 105 effect sizes from 32 primary studies employing meaning-focused word-learning activities with 1,964 participants with typical cognitive functioning. The random-effects meta-analysis yielded a mean effect size of g = 1.05,…

There remains considerable disagreement about which factors drive second language (L2) ultimate attainment. Age of onset (AO) appears to be a robust factor, lending support to theories of maturational constraints on L2 acquisition. The present study is an investigation of factors that influence grammatical and lexical complexity at the stage of L2…

Research in adults has shown that novel words are encoded rather swiftly but that their semantic integration occurs more slowly and that studying definitions presented in a written modality may benefit integration. It is unclear, however, how semantic integration proceeds in children, who (compared to adults) have more malleable brains and less…

Spoken language data were collected from six adult second language (L2) English learners over a year-long period in order to explore the development of word polysemy and frequency use. The data were analyzed both quantitatively and qualitatively. In the first analysis, the growth of WordNet polysemy values and CELEX word frequency values were…

This study examines the effects of learning context and age on second language development by comparing the language gains, measured in terms of oral and written fluency, lexical and syntactic complexity, and accuracy, experienced by four groups of learners of English: children in a study abroad setting, children in their at-home school, adults in…

Examines the learning and use of academic English words by students who differ socioculturally. Argues that the Greco-Latin vocabulary of English offers various levels of potential difficulty for students from different class, cultural, or linguistic social factions. Infers some changes to practices in native and second language academic English…

Reports on the third year of a research project to document and evaluate an innovative foreign language in elementary schools (FLES) program in Japanese for Grades K-5. Findings indicate that the children progressed considerably in foreign language proficiency and developed positive attitudes toward language learning. (28 references) (Author/CK)
