There is current research consensus that second language (L2) learners are able to adequately comprehend general English written texts if they know 98% of the words that occur in the materials. This important finding prompts an important question: How much English vocabulary do English as a second language (ESL) learners need to know to achieve…

The vocabulary research of the 1980s and 1990s brought a breath of fresh air into the language classroom. Teachers in many remote EFL locations had long suspected that vocabulary was their learners' main challenge, but there was little research evidence to confirm this or say what to do about it. Then, suddenly, work by Nation, Laufer, Meara,…

Researchers have developed several tests of receptive vocabulary knowledge suitable for use with learners of English, but options are few for learners of French. This situation motivated the authors to create a new vocabulary size measure for French, the "Test de la taille du vocabulaire" (TTV). The measure is closely modelled on…

Opportunities for incidental vocabulary acquisition were explored in a 121,000-word corpus of teacher talk addressed to advanced adult learners of English as a second language (ESL) in a communicatively-oriented conversation class. In contrast to previous studies that relied on short excerpts, the corpus contained all of the teacher speech the…

This study reports on the design and testing of an integrated suite of vocabulary training games for Nintendo[TM] collectively designated "My Word Coach" (Ubisoft, 2008). The games' design is based on a wide range of learning research, from classic studies on recycling patterns to frequency studies of modern corpora. Its general usage…

Many language courses now offer access to simplified materials graded at various levels of proficiency so that learners can read at length in their new language. An assumed benefit is the development of large and rapidly accessed second language (L2) lexicons. Studies of such extensive reading (ER) programs indicate general language gains, but few…

The study drew on an 80,000-word corpus consisting of narrative texts produced in response to picture prompts by 210 beginner-level francophone learners of English (11-12-year-olds). The unique feature of the corpus is its longitudinal character: The samples were collected at four 100-hour intervals of intensive language instruction, during which…

This replication study demonstrated that Jordanian college students studying English recognized the meanings of new words and built associations between them after comprehension-focused extensive reading. Controlled book-length reading generated more incidental word learning and a higher pickup rate than shorter tasks. Word frequency did not make…

Presents a case study that tests a mathematical model for its ability to predict second language vocabulary gains achieved through reading. To overcome the problem of small word gains noted in earlier studies of incidental acquisition, an adult learner of Dutch read a lengthy text and was tested on hundreds of words. The participant's gains were…

This paper examines how collaborative on-line databases can be used to meet the need for individualized instruction for academic vocabulary learners intending to do university work in English. It is argued that effective teaching and course design for preparing non-native English speaking students for study at English language universities must be…

University students used a set of existing and purpose-built on-line tools for vocabulary learning in an experimental ESL course. The resources included concordance, dictionary, cloze-builder, hypertext, and a database with interactive self-quizzing feature (all freely available at www.lextutor.ca). The vocabulary targeted for learning consisted…
