Infant vocabulary development assessed with a British communicative development inventory

Communicative Development Inventories (CDIs) were collected from 669 British children aged between 1;0 and 2;1. Comprehension and production scores in each age group are calculated. This provides norming data for the British infant population. The influence of socioeconomic group on vocabulary scores is considered and shown not to have a significant effect. The data from British infants is compared to data from American infants (Fenson, Dale, Reznick, Bates, Thal & Pethick, 1994). It is found that British infants have lower scores on both comprehension and production than American infants of the same age.

Children's Vocabulary Development : The role of parental input, vocabulary composition and early communicative skills

The aim of this thesis is to examine the early vocabulary development of a sample of Swedish children in relation to parental input and early communicative skills. Three studies are situated in an overall description of early language development in children. The data analyzed in the thesis was collected within a larger project at Stockholm University (SPRINT- “Effects of enhanced parental input on young children’s vocabulary development and subsequent literacy development” [VR 2008-5094]). Data analysis was based on parental report via SECDI, the Swedish version of the MacArthur-Bates Communicative Development Inventories, and audio recordings. One study examined parental verbal interaction characteristics in three groups of children with varying vocabulary size at 18 months. The stability of vocabulary development at 18 and 24 months was investigated in a larger study, with focus on children’s vocabulary composition and grammatical abilities. The third study examined interrelations among early gestures, receptive and productive vocabulary, and grammar measured with M3L, i.e. three longest utterances, from 12 to 30 months. Overall results of the thesis highlight the importance of early language development. Variability in different characteristics in parental input is associated with variability in child vocabulary size. Children with large early vocabularies exhibit the most stability in vocabulary composition and the earliest grammatical development. Children’s vocabulary composition may reflect individual stylistic variation. Use of early gestures is associated differentially with receptive and productive vocabulary. Results of the thesis have implications for parents, child- and healthcare personnel, as well as researchers and educational practitioners. The results underscore the importance of high quality in adult-child interaction, with rich input fine-tuned to children’s developmental levels and age, together with high awareness of early language development.

Extending the Simple Knowledge Organization System for Concept Management in Vocabulary Development Applications

In this article, we describe the development of an exten- sion to the Simple Knowledge Organization System (SKOS) to accommodate the needs of vocabulary devel- opment applications (VDA) managing metadata schemes and requiring close tracking of change to both those schemes and their member concepts. We take a neo- pragmatic epistemic stance in asserting the need for an entity in SKOS modeling to mediate between the abstract concept and the concrete scheme. While the SKOS model sufficiently describes entities for modeling the current state of a scheme in support of indexing and search on the Semantic Web, it lacks the expressive power to serve the needs of VDA needing to maintain scheme historical continuity. We demonstrate prelimi- narily that conceptualizations drawn from empirical work in modeling entities in the bibliographic universe, such as works, texts, and exemplars, can provide the basis for SKOS extension in ways that support more rig- orous demands of capturing concept evolution in VDA.

Once upon a time, there was a pulchritudinous princess…: the role of word definitions and multiple story contexts in children’s learning of difficult vocabulary

The close relationship between children’s vocabulary size and their later academic success has led researchers to explore how vocabulary development might be promoted during the early school years. We describe a study that explored the effectiveness of naturalistic classroom storytelling as an instrument for teaching new vocabulary to six- to nine-year-old children. We examined whether learning was facilitated by encountering new words in single versus multiple story contexts, or by the provision of age-appropriate definitions of words as they were encountered. Results showed that encountering words in stories on three occasions led to significant gains in word knowledge in children of all ages and abilities, and that learning was further enhanced across the board when teachers elaborated on the new words’ meanings by providing dictionary definitions. Our findings clarify how classroom storytelling activities can be a highly effective means of promoting vocabulary development.

A Story of English Language Learning – How Can Children’s Literature be Used in Teaching Vocabulary to Young English Language Learners? : - A Literature Review

This study aims to find research relating to the use of children’s literature to promote vocabulary development in young children, particularly English language learners in Sweden. The main questions address how (methods) children’s literature can be used and why (reasons) children’s literature is often recommended for the teaching of vocabulary to young learners. The study also aims to explore reasons against the use of children’s literature in vocabulary teaching found in previous research. A systematic literature review was carried out, including results from five empirical studies. The studies involved native speakers, second language learners and foreign language learners from various backgrounds. The results suggest that while research has shown children’s literature to be a good tool to use with young learners, careful lesson planning needs to be carried out. Direct instruction and scaffolding using pictures, technology and gestures is recommended. Hence, the teacher plays an important part for the vocabulary development using children’s literature in the classroom.

Using parent report to assess bilingual vocabulary acquisition: a model from Irish

This chapter describes the adaptation of a parent report instrument on early language development to a bilingual context. Beginning with general issues of adapting tests to any language, particular attention is placed on the issue of using parents as evaluators of child language acquisition of a minority language in a bilingual context. In Ireland, Irish is the first official language and is spoken by about 65,000 people on a daily basis. However all Irish speakers are bilingual, and children are exposed to the dominant English language at an early age. Using an adaptation of a parent report instrument, 21 typically developing children between 16 and 40 months were assessed repeatedly over two years to monitor their language development. The form allowed parents to document their children’s vocabulary development in both languages. Results showed that when knowledge of both languages was accounted for, the children acquired vocabulary at rates similar to those of monolingual speakers and used translational equivalents relatively early in language development. The study also showed that parents of bilingual children could accurately identify and differentiate language development in both of the child’s languages. Recommendations for adapting and using parent report instruments in bilingual language acquisition contexts are outlined.

A Longitudinal Investigation of Infant Gesture Use and Parent Speech: Unique and Dynamic Influences on Infant Vocabulary Acquisition

How do infants learn word meanings? Research has established the impact of both parent and child behaviors on vocabulary development, however the processes and mechanisms underlying these relationships are still not fully understood. Much existing literature focuses on direct paths to word learning, demonstrating that parent speech and child gesture use are powerful predictors of later vocabulary. However, an additional body of research indicates that these relationships don’t always replicate, particularly when assessed in different populations, contexts, or developmental periods.

The current study examines the relationships between infant gesture, parent speech, and infant vocabulary over the course of the second year (10-22 months of age). Through the use of detailed coding of dyadic mother-child play interactions and a combination of quantitative and qualitative data analytic methods, the process of communicative development was explored. Findings reveal non-linear patterns of growth in both parent speech content and child gesture use. Analyses of contingency in dyadic interactions reveal that children are active contributors to communicative engagement through their use of gestures, shaping the type of input they receive from parents, which in turn influences child vocabulary acquisition. Recommendations for future studies and the use of nuanced methodologies to assess changes in the dynamic system of dyadic communication are discussed.

Lexicon for the Sensory Description of Australian Native Plant Foods and Ingredients

Understanding and describing Australian flavor has proved to be a challenge for marketers of native foods because of the diversity of unique flavor signatures exhibited. Descriptive analysis techniques were applied, using a panel of 11 experienced judges, to define and articulate the sensory properties of 18 key commercial Australian native plant foods and ingredients including fruits, herbs and spices. Quantitative descriptive data were transformed into concise and accurate verbal descriptions for each of the species. The sensory language developed during the vocabulary development panel sessions was combined, categorized and ordered to develop a sensory lexicon specific for the genre. The language developed to describe the foods and ingredients was diverse and distinctly Australian including aromas such as musk, rosella, citrus and spiced tea to eucalypt, bush scrub, fresh beetroot and wheat biscuit. Practical Applications This work provides a clear, useful means of characterizing and accurately describing the flavors of Australian native plant foods and ingredients. This information has been communicated to the native food industry, chefs, formulators, food technologists and flavor experts, and provides knowledge that will assist the wider food industry to successfully develop flavor blends and produce food products from native food ingredients. It is anticipated that extension of this information to both the local and international food markets will stimulate a renewed interest in Australian native ingredients and open new market opportunities for the industry. The data developed by this research have also formed the basis of quality control targets for emerging native foods and ingredients.

Phonological sensitivity and reading: evidence from precocious readers

This paper reports the results from a study investigating the level of phonological sensitivity, letter knowledge and reading ability of two groups of children between the ages of 5 and 7 years. One group of children were identifies as being fluent readers at the age of 5 years, before they had begun school. These children were paired with a group of children of the same age and vocabulary development but who were not yet reading. The performance of the two groups of children on the tasks measuring phonological sensitivity confirmed the view of Stanovich (1986, 1992) that phonological sensitivity lies on a continuum from shallow to deep. Shallow levels of phonological sensitivity, tapped by rhyming tasks, seem to be necessary for reading to progress whereas deeper levels of sensitivity develop later and have a more reciprocal relationship to the reading process.

The effects of using rap music on the fluency skills of 2nd grade African American students

A concern for both educators and policy makers is how to increase the reading achievement of African American students. Studies have shown that rap music, which has its roots in the African American community, can be used as a tool to facilitate this increase, specifically how using rap songs in reading lessons can improve a child's reading motivation, information recall, and vocabulary development. There are also studies on how repeated reading of a text can help improve a child's reading fluency. Yet, there are no studies that combine rap music and repeated reading of a text. This study describes the effects of using a culturally responsive reading strategy on the fluency, decoding, and comprehension skills of African American students. ^ The sample consisted of 105 African American students within eight, second grade classrooms at two different elementary schools. The classes were randomly selected and assigned to the rap group or the control group. Students received eight half-hour sessions using either a rap text or a traditional text in a repeated reading lesson. All of the students were pre-tested and post-tested on the Oral Reading Fluency and the Nonsense Word Fluency portions of the Dynamic Indicators of Basic Literacy Skills Test. Additionally, a researcher constructed comprehension quiz was given to the students at the beginning, middle, and end of the study. Research questions were analyzed using ANOVAs and t tests. ^ The hypotheses were not supported but there was some evidence that rap music in a reading lesson helped improve the fluency skills of African American students at one of the schools. The results also revealed that rap music used in a reading lesson initially improved the comprehension skills of African American students. The rap treatment may not have worked best overall because of the lack of intensity of the treatment. ^ The study has shown some evidence to support using culturally appropriate materials such as rap with students. There needs to be more research on the interaction between teaching methods, materials, and students. ^

Collocations used in DELE B1 reading tests

This paper aims to investigate the use of collocations in DELE B1. We select the reading texts from DELE B1 (2010 to 2014) as research data. The investigation includes: First of all, we will study the theory of collocation and the classification as well as its application to the foreign language learning and teaching. Second, we will analyze the types of collocation annotated by Corpus Tool. Third, we tend to calculate the frequency use of each type of collocations written in Spanish reading texts. Next, we will discuss the interrelationship between collocations and text themes. Finally, we would like to compare the differences of results of collocation use between these two corpus tools: Corpus Tool and Corpus del Español in order to understand the native speakers’ preference of use collocations as well as to provide supplementay materials for teaching of Spanish reading. We hope that the expected results of our research will offer useful references for improving students' Spanish reading comprehension to pass DELE B1 examinations.

Liens entre les pratiques parentales préscolaires en littéracie et la lecture à 8 ans : Médiation par le vocabulaire et la connaissance des lettres

Ce mémoire doctoral s’intéresse aux pratiques parentales en littéracie comme prédicteurs des différences précoces en lecture. Les études antérieures ont rapporté des liens préférentiels entre deux types de pratiques parentales en littéracie, deux habiletés préalables à la lecture et le développement de la lecture au primaire. D’une part, l’enseignement des lettres par le parent, une pratique formelle, contribuait à la connaissance des lettres, laquelle était un prédicteur des habiletés de lecture de l’enfant. D’autre part, la lecture parent-enfant ainsi que l’exposition aux livres, des pratiques informelles, prédisaient le développement langagier de l’enfant, lequel contribuerait plus spécifiquement à la compréhension en lecture. L’hypothèse selon laquelle des processus de médiation sont impliqués a été proposé par plusieurs chercheurs mais, aucun n’avait testé formellement cette hypothèse. De plus, la contribution des pratiques parentales en littéracie était évaluée une seule fois, en maternelle ou au début de la première année du primaire, ce qui ne permettait pas d’identifier l’âge vers lequel il devient pertinent d’introduire l’enfant au monde littéraire. L’objectif du mémoire était donc d’évaluer formellement un modèle de double médiation à l’aide d’analyses acheminatoires tout en considérant l’exposition à la littéracie tout au long de la petite enfance. En accord avec les liens préférentiels suggérés dans la littérature, on a constaté que l’enseignement des lettres par les parents à 4 et 5 ans prédisent indirectement les habiletés en lecture (8 ans; décodage et compréhension en lecture) via leur contribution à la connaissance des lettres (5 ans). Également, le vocabulaire réceptif de l’enfant (5 ans) était un médiateur des contributions de la lecture parent-enfant à 2.5, 4 et 5 ans, à la compréhension en lecture (8 ans). Ce mémoire souligne l’importance d’initier les enfants à la littéracie en bas âge afin de supporter leur acquisition subséquente de la lecture.

SES-RELATED DIFFERENCES IN WORD LEARNING: EFFECTS OF COGNITIVE INHIBITION AND WORD LEARNING

Socioeconomic status (SES) influences language and cognitive development, with discrepancies particularly noticeable in vocabulary development. This study examines how SES-related differences impact the development of syntactic processing, cognitive inhibition, and word learning. 38 4-5-year-olds from higher- and lower-SES backgrounds completed a word-learning task, in which novel words were embedded in active and passive sentences. Critically, unlike the active sentences, all passive sentences required a syntactic revision. Measures of cognitive inhibition were obtained through a modified Stroop task. Results indicate that lower-SES participants had more difficulty using inhibitory functions to resolve conflict compared to their higher-SES counterparts. However, SES did not impact language processing, as the language outcomes were similar across SES background. Additionally, stronger inhibitory processes were related to better language outcomes in the passive sentence condition. These results suggest that cognitive inhibition impact language processing, but this function may vary across children from different SES backgrounds

Ontologies and the Semantic Web: Problems and Perspectives for LIS Professionals

Many years have passed since Berners-Lee envi- sioned the Web as it should be (1999), but still many information professionals do not know their precise role in its development, especially con- cerning ontologies –considered one of its main elements. Why? May it still be a lack of under- standing between the different academic commu- nities involved (namely, Computer Science, Lin- guistics and Library and Information Science), as reported by Soergel (1999)? The idea behind the Semantic Web is that of several technologies working together to get optimum information re- trieval performance, which is based on proper resource description in a machine-understandable way, by means of metadata and vocabularies (Greenberg, Sutton and Campbell, 2003). This is obviously something that Library and Information Science professionals can do very well, but, are we doing enough? When computer scientists put on stage the ontology paradigm they were asking for semantically richer vocabularies that could support logical inferences in artificial intelligence as a way to improve information retrieval systems. Which direction should vocabulary development take to contribute better to that common goal? The main objective of this paper is twofold: 1) to identify main trends, issues and problems con- cerning ontology research and 2) to identify pos- sible contributions from the Library and Information Science area to the development of ontologies for the semantic web. To do so, our paper has been structured in the following manner. First, the methodology followed in the paper is reported, which is based on a thorough literature review, where main contributions are analysed. Then, the paper presents a discussion of the main trends, issues and problems concerning ontology re- search identified in the literature review. Recom- mendations of possible contributions from the Library and Information Science area to the devel- opment of ontologies for the semantic web are finally presented.
