Two commonly used test types to assess vocabulary knowledge for the purpose of reading are size and levels tests. This article first reviews several frequently stated purposes of such tests (e.g., materials selection, tracking vocabulary growth) and provides a reasoned argument for the precision needed to serve such purposes. Then three sources of…

Purpose: In this article, we review the role of retrieval practice on the word learning and retention of children with specific language impairment (SLI). Method: Following a brief review of earlier findings on word learning in children with SLI and the assumptions behind retrieval practice, four experiments are described that compared novel words…

Currently, a relatively large number of spoken and written conventionalized expressions have been collected, catalogued, and systematized. In language pedagogy, a clear implication is that teaching grammar and vocabulary is likely to be more complicated than working with syntactic rules and single-word items. Old and new insights associated with…

One of the questions facing language instructors is how direct vocabulary instruction should be. Much recent research into vocabulary acquisition and studies of learning strategies strongly indicates that the explicit vocabulary learning vs. implicit vocabulary learning issue is not a dichotomy, but rather a continuum (Hunt and Belgar, 2005; Lee…

This paper explores the concurrent and predictive validity of the long and short forms of the Galician version of the MacArthur-Bates CDI (IDHC). Forty-two Galician-speaking children were longitudinally evaluated at age 1 ; 6, 2 ; 0 and 4 ; 0. On the first two occasions, the subjects' vocabulary and grammar skills were assessed through the IDHC.…

This investigation examined the ability of 44 preschool children to acquire novel words embedded in storybook contexts. Previous investigations of word learning have typically consisted of novel words for which synonyms exist. It is argued that the acquisition of unfamiliar words that refer to existing concepts that already have labels is not…

Does early gesture use predict later productive and receptive vocabulary in children with pre- or perinatal unilateral brain lesions (PL)? Eleven children with PL were categorized into 2 groups based on whether their gesture at 18 months was within or below the range of typically developing (TD) children. Children with PL whose gesture was within…

Broad-stroke approaches to vocabulary teaching in preschool include effective instructional elements, yet may be too ill-structured to affect the vocabulary learning of children experiencing serious delays. Using a formative research approach, this study examines the design potential of a supplemental vocabulary instruction technique that…

There is a growing awareness of the importance of academic vocabulary, and more generally, of academic language proficiency, for students' success in school. There is also a growing body of research on the nature of the demands that academic language places on readers and writers, and on interventions to help students meet these demands. In this…

There are normally two major research reasons for assessing second and foreign language (L2) knowledge: either to gauge a participant's actual level of competence/proficiency or to assess language development over a period of time. In testing, the corresponding contrasts are typically referred to as proficiency tests on the one hand and…

This study investigates the effects of receptive and productive vocabulary tasks on learning collocation and meaning. Japanese English as a foreign language students learned target words in three glossed sentences and in a cloze task. To determine the effects of the treatments, four tests were used to measure receptive and productive knowledge of…

Children from immigrant, low-income families in the Netherlands start school with a limited vocabulary in the language of instruction; therefore, this places them at risk for developing reading difficulties. Exposure to books is assumed to reduce their 2nd language (L2) vocabulary disadvantage. In this experiment, we examined the effects of video…

This study examined the relationship between viewing an infant DVD and expressive and receptive language outcomes. Children between 12 and 15 months were randomly assigned to view "Baby Wordsworth," a DVD highlighting words around the house marketed for children beginning at 12 months of age. Viewings took place in home settings over 6 weeks.…

Background: Increasing evidence suggests that childhood language problems persist into early adulthood. Nevertheless, little is known about how individual and environmental characteristics influence the language growth of individuals identified with speech/language problems. Method: Individual growth curve models were utilised to examine how…

This investigation examined the Spanish and English receptive vocabulary and language comprehension abilities of bilingual preschoolers who attended Head Start over a two-year period. It was hypothesised that bilingual children's development would follow linear trajectories and that the development of children who were only exposed to Spanish in…
