Contrasting orthographically similar words facilitates adult second language vocabulary learning

When learners acquire new words in a second language (L2), their lexical representations and links are initially imprecise. As new, similar words are learned, these representations must become more specific to avoid errors. This study investigated whether contrasting similar words triggers this sharpening process and facilitates learning. In a multiple-choice learning task, 114 adults acquired orthographically and semantically similar L2 (pseudo)words by either contrasting them or not. In Experiment 1, participants contrasted the L2 words, and in Experiment 2 they contrasted words in their first language. Only contrasting orthographically similar L2 words facilitated their acquisition. We conclude that contrasting underspecified representations serves as a learning mechanism that guides attention to relevant lexical information. As such, it enables learners to build more specific representations and is conducive to learning. Possibilities for further research and potential implications for L2 vocabulary instruction are discussed.     

Knowledge of words, knowledge about words: Dimensions of vocabulary in first and second language learners in sixth grade

Despite acknowledging the complex nature of vocabulary knowledge, researchers have rarely investigated the dimensionality of this construct empirically. This study was designed to test a multi-dimensional model of English vocabulary knowledge for sixth-grade students from linguistically diverse backgrounds (n = 584). Participants included language minority students learning English as a second language (L2) and students who learned English as a first language (L1). Students were assessed on 13 reading-based measures tapping various aspects of vocabulary knowledge. Using multiple-group confirmatory factor analysis, we found that vocabulary was comprised of three highly related, but distinct dimensions—breadth, contextual sensitivity, and morphological awareness. This three-dimensional model was found to hold for L2 learners as well as L1 speakers. Although the L2 learners were statistically significantly lower than the L1 students on all three dimensions, the magnitude of the difference for morphological awareness (d = .37) was somewhat smaller than that for vocabulary breadth (d = .52) and contextual sensitivity (d = .49). Results were similar for a subsample of Spanish-speaking L2 learners and for the full sample of L2 learners from various home language groups. Findings support a distinction between word-specific and word-general knowledge in understanding individual and group differences in vocabulary.     

First and second language vocabulary affect early second language reading comprehension development

The aim of this study was to examine variation in early reading comprehension development for second language (L2) readers compared with first language (L1) readers and to investigate the impact of vocabulary knowledge in their first and second language. Participants were 75 Dutch monolingual children (L1 readers) and 71 Turkish–Dutch bilingual children (L2 readers), aged between 6 and 8 years old at the start of the study. In a longitudinal design, three waves of data were collected across second and third grades. The L2 readers had lower reading comprehension scores than the L1 readers on average, but this performance gap narrowed over time. To further investigate variation among the L2 readers, four categorical subgroups of L2 readers were identified with varying levels of L1 (Turkish) and L2 (Dutch) vocabulary knowledge by means of cluster analysis. Group membership was related to reading comprehension and showed an interaction with time, indicating that reading comprehension performance of the two L2 subgroups with high L1 vocabulary increased more over time compared with L1 readers. The L2 subgroup with high vocabulary in both languages even caught up with their monolingual peers in third grade. These findings demonstrate how individual differences in L1 and L2 vocabulary knowledge explain variation in early L2 reading comprehension development and highlight the importance of considering L2 readers' first language in research and education.     

Keywords and vocabulary acquisition: Some words of caution about words of assistance

Consistent results of two experiments with relatively technical, native language vocabulary, showed that effectiveness of keyword methods depended upon whether meanings of words to be learned were abstract or concrete and whether comprehension was assessed immediately or after a delay. Keywords bearing acoustical similarities to vocabulary items whose meanings were presented as sentences consistently facilitated students’ retention of the meanings of concrete items on immediate posttests. However, in contrast to recent research on foreign language vocabulary having simpler definitions, these experiments showed that it may be difficult to use the keyword method to aid long-term retention with moderately complex. abstract, native language vocabulary. Parts of this study, which was partially supported by the Kansas State University Bureau of General Research, were presented at the Annual Meeting of the American Educational Research Association, Boston, 1980.

The development of seventh graders' views of nature of science

This study investigated the development in students' nature of science (NOS) views in the context of an explicit inquiry‐oriented instructional approach. Participants were 18 seventh‐grade students who were taught by a teacher with “appropriate” knowledge about NOS. The intervention spanned about 3 months. During this time, students were engaged in three inquiry‐oriented activities that were followed by reflective discussions of NOS. The study emphasized the tentative, empirical, inferential, and creative aspects of NOS. An open‐ended questionnaire, in conjunction with semi‐structured interviews, was used to assess students' views before, during, and after the intervention. Before instruction, the majority of students held naïve views of the four NOS aspects. During instruction, the students acquired more informed and “intermediary” views of the NOS aspects. By the end of the intervention, the students' views of the NOS aspects had developed further still into informed and “intermediary.” These findings suggest a developmental model in which students' views develop along a continuum during which they pass through intermediary views to reach more informed views. Implications for teaching and learning of NOS are discussed. © 2007 Wiley Periodicals, Inc. J Res Sci Teach 45: 470–496, 2008

The development of word retrieval abilities in the second year and its relation to early vocabulary growth

The present research investigated the development of word retrieval abilities late in the second year when most children display a marked increase in word production. When asked what was hidden in a given box, children with still quite limited productive vocabularies were reliably less likely to produce the labels of the hidden objects than were children with larger productive vocabularies even though (1) all children could name those objects and (2) all children did well when asked to find those same hidden objects. Additionally, the provision of pictorial cues facilitated word retrieval, especially in the early stage of lexical development. Naming errors during a naturalistic book-reading session peaked in children whose productive vocabularies had recently begun to expand, further suggesting that word retrieval processes undergo significant changes at this time.     

Academic vocabulary and middle school English learners: an intervention study

The goal of this experimental intervention study was to determine if evidence-based instructional strategies for general vocabulary words are effective with middle school English learner (EL) students and academic vocabulary words. Participants showed significantly more growth in their knowledge of academic vocabulary during the treatment condition than during the control condition. A secondary goal of this study was to examine the predictive utility of students’ English language proficiency, and students’ general vocabulary knowledge in English was a positive predictor for their academic vocabulary growth during the intervention. However, participants’ growth during the control period had the greatest predictive utility for their growth during the intervention. Furthermore, this relationship was negative, suggesting that the intervention had the greatest benefits for students who made the least progress in English vocabulary in the absence of the intervention. Implications for instruction, policy, and future research are presented.     

Syllable and rime patterns for teaching reading: Analysis of a frequency-based vocabulary of 17,602 words

A frequency-based vocabulary of 17,602 words was compiled and analyzed in order to group words with recurring syllable and rime patterns for teaching reading. The role of the rime unit (e.g.,ite inkite andinvite) in determining vowel pronunciation was central to the analysis because of the difficulty that the ambiguity of English vowel spelling presents to children who do not learn to read words easily. Vowel pronunciation in each orthographic rime was examined, both for its consistency in all words in which the rime occurs and for regularity, defined as conformity to the most frequent pronunciation for each vowel spelling in each of six orthographic syllable types. Of the 824 different orthographic rimes, 616 occur in rime families as the building blocks of almost all the 43,041 syllables of the words. These rimes account for a striking amount of patterning in the orthography: 436 are both regular and consistent in pronunciation (except where a single exception word occurs); another 55 are consistent but not regular. Of the remaining 125, only 86 have less than a 90 percent level of consistency. The high order of congruence of orthographic and phonological rimes suggests their usefulness as units for teaching reading.

Effects of individualized word retrieval in kindergarten vocabulary intervention

We examined the effects of adaptive word retrieval intervention on a classroom vocabulary program on children’s vocabulary acquisition in kindergarten. In the experimental condition, word retrieval was provided in a classroom vocabulary program, combining implicit and explicit vocabulary instructions. Children performed extra word retrieval activities and received semantic feedback for words they did not learn during the classroom vocabulary program. Eighty-seven children were in the experimental condition, and 115 children were in the classroom vocabulary control condition. Results showed the adaptive word retrieval intervention to stimulate higher learning gains than the classroom vocabulary program on the learning of the target words. Children in the experimental condition also showed transfer effects; they described more words on a standardized expressive vocabulary test than children in the control condition. The research findings suggest additional value of word retrieval with feedback for classroom vocabulary learning.     

Reading with vocabulary intervention: evaluation of an instruction for children with poor response to reading intervention

Interventions combining phonically based reading instruction with phonological training are generally effective for children with reading (decoding) difficulties. However, a minority of children respond poorly to such interventions. This study explored the characteristics of children who showed poor response to reading intervention and aimed to improve their literacy and language skills via a new theoretically motivated intervention. Twelve 8‐year‐old treatment poor responders with severe and persisting reading difficulties participated. A 9‐week reading intervention incorporating reading, phonological and vocabulary training was implemented. Before the intervention began the children showed almost no progress over 6 months of regular classroom education, on measures of oral language and literacy. Over the intervention period improvements were made on measures of reading, phonological awareness and language skills, which were maintained 6 months later. Although the intervention was effective, it should be noted that most children remained poor readers and require ongoing remediation.

An investigation of whether fantasy books,compared to same topic nonfiction,promote second graders' creativity

Narrowing of the curriculum because of standardised testing has caused creativity to be neglected in many schools; integration into reading instruction may provide a solution. This repeated measures study incorporated figural transformation drawings after a read-aloud of a book highlighting nutrition information as a way to both review book comprehension and integrate creativity. Nineteen second graders, aged 7–9 years from Iowa, USA, participated in 16 weekly trials, alternating between a nonfiction nutrition book and a fantasy book presenting true nutrition concepts. Results showed significantly greater creativity generally and in specific creative skill areas under the fantasy condition.     

Mind the gap: vocabulary development in the primary curriculum

In the context of an on-going project emphasising the centrality of speaking and listening in the primary curriculum, the present article turns to vocabulary development: to the wide differences characterising primary age children in this regard, to their consequent unequal access to the wider curriculum, and to means by which such deficiencies may be addressed. This article reports how, given a variety of in-service supports, teachers in a small group of schools undertook to define relevant aims and objectives and to include a range of appropriate approaches in their teaching. Particular emphasis was placed upon active and ‘explicit’ vocabulary instruction. The viability and effectiveness of the strategies employed were assessed through analysis of a range of collected data; numerous examples of which are presented and evaluated here. This article concludes by reviewing such matters from teachers’ as well as pupils’ perspectives, and by emphasising the role of explicit instruction within the various approaches discussed.
