Vocabulary learning

This article addresses the question of how to account for the growth in vocabulary knowledge that occurs during the elementary school years. Areas examined include the ways that word meanings are communicated, direct teaching of meanings vocabulary instruction as a part of reading instruction, and deriving and learning word meanings from verbal context. Taken singly, neither direct instruction of meanings nor learning word meanings from context seems to account all that well for the growth in vocabulary that is thought to occur.     

Speaking up for vocabulary: reading skill differences in young adults

This study is part of a broader project aimed at developing cognitive and neurocognitive profiles of adolescent and young adult readers whose educational and occupational prospects are constrained by their limited literacy skills. We explore the relationships among reading-related abilities in participants ages 16 to 24 years spanning a wide range of reading ability. Two specific questions are addressed: (a) Does the simple view of reading capture all nonrandom variation in reading comprehension? (b) Does orally assessed vocabulary knowledge account for variance in reading comprehension, as predicted by the lexical quality hypothesis? A comprehensive battery of cognitive and educational tests was employed to assess phonological awareness, decoding, verbal working memory, listening comprehension, reading comprehension, word knowledge, and experience with print. In this heterogeneous sample, decoding ability clearly played an important role in reading comprehension. The simple view of reading gave a reasonable fit to the data, although it did not capture all of the reliable variance in reading comprehension as predicted. Orally assessed vocabulary knowledge captured unique variance in reading comprehension even after listening comprehension and decoding skill were accounted for. We explore how a specific connectionist model of lexical representation and lexical access can account for these findings.     

Acquisition of three word knowledge aspects through reading

A number of studies have shown that second or foreign language learners can acquire vocabulary through reading. The aim of the study was to investigate (a) the effects of reading an authentic novel on the acquisition of 3 aspects of word knowledge: spelling, meaning, and collocation; (b) the influence of reading on the acquisition of partial and deeper knowledge of the words; and (c) the relationship between word frequency and learning gains. The results show that there was significant improvement in all three aspects of word knowledge. The measuring instrument detected greater partial than deeper knowledge gains in word meanings and collocations. The greatest learning gains in all three aspects of word knowledge were demonstrated for the words that occurred between 11 and 20 times in the text. The findings suggest that incorporation of extensive reading into language learning programs can contribute to significant improvement of learners' vocabulary knowledge.     

Does knowledge of connectives play a unique role in the reading comprehension of English learners and English‐only students?

Connectives (e.g., although, meanwhile) carry abstract meanings and often signal key relationships between text ideas. This study explored whether understanding of connectives represents a unique domain of vocabulary knowledge that provides special leverage for reading comprehension, and whether the contribution of knowledge of connectives to reading comprehension differs for students from distinct language backgrounds. Understanding of connectives, word reading efficiency and breadth of vocabulary knowledge of 75 English language learners (ELLs) and 75 English‐only (EO) fifth graders were assessed. Hierarchical multiple regression techniques revealed that understanding of connectives explained a sizeable and significant portion of unique variance in comprehension beyond that explained by breadth of vocabulary knowledge when controlling for word reading efficiency. The magnitude of this relationship was larger for EO students than for ELLs. Findings indicate that connectives play an important role in comprehension, but that the strength of their influence varies by readers’ linguistic background.     

The effects of speech production and vocabulary training on different components of spoken language performance

A group of 21 hard-of-hearing and deaf children attending primary school were trained by their teachers on the production of selected consonants and on the meanings of selected words. Speech production, vocabulary knowledge, reading aloud, and speech perception measures were obtained before and after each type of training. The speech production training produced a small but significant improvement in the percentage of consonants correctly produced in words. The vocabulary training improved knowledge of word meanings substantially. Performance on speech perception and reading aloud were significantly improved by both types of training. These results were in accord with the predictions of a mathematical model put forward to describe the relationships between speech perception, speech production, and language measures in children (Paatsch, Blamey, Sarant, Martin, & Bow, 2004). These training data demonstrate that the relationships between the measures are causal. In other words, improvements in speech production and vocabulary performance produced by training will carry over into predictable improvements in speech perception and reading scores. Furthermore, the model will help educators identify the most effective methods of improving receptive and expressive spoken language for individual children who are deaf or hard of hearing.     

The Effect of Questioning Style During Storybook Reading on Novel Vocabulary Acquisition of Preschoolers

The effects of adult questioning on children’s novel word acquisition during storybook reading were investigated. Three-year-olds were assigned to one of three conditions: vocabulary eliciting questions, noneliciting questions, and no questions (control). General vocabulary comprehension and novel word knowledge were equivalent across the groups before the storybook reading intervention. Children were read 3 storybooks repeatedly across 4 reading sessions and were tested for production and comprehension of novel words in the final session. Children’s novel word comprehension increased more in both question conditions than in the control condition, suggesting that type of question is not as important to word learning as children’s active engagement in discussion about novel words in general. Novel word production was not strongly affected by any of the reading conditions. However, asking children noneliciting questions did appear to foster production of new words more than not asking questions at all.     

Evaluating the role of polysemous word knowledge in reading comprehension among bilingual adolescents

This study reports on the development of an assessment to measure bilingual adolescents’ knowledge of polysemous vocabulary and explores the contribution of polysemous word knowledge to reading comprehension among those students. Spanish–English bilingual students in seventh grade (n = 107) completed a battery of standardized reading and language measures along with a researcher-designed measure of their knowledge of the academic senses of words that also have casual, everyday meanings. Item-response theory analyses and correlational analyses provided validity evidence for the assessment. Regression analyses indicated that students’ knowledge of academic senses of polysemous words predicted their reading comprehension, even after controlling for their knowledge of the casual sense of the same words, vocabulary breadth, and decoding skills. Findings suggest that comprehension of grade-level texts is uniquely predicted by the ability to recognize the meanings of familiar words when they appear in academic contexts.     

Models of Vocabulary Acquisition: Direct Tests and Text-Derived Simulations of Vocabulary Growth

Determining word meanings that ought to be taught or introduced is important for educators. A sequence for vocabulary growth can be inferred from many sources, including testing children’s knowledge of word meanings at various ages, predicting from print frequency, or adult-recalled Age of Acquisition. A new approach, Word Maturity, is based on applying Latent Semantic Analysis to patterns of word occurrences in texts used with children. This article reports substantial correlations in the .67 to .74 range between Word Maturity estimates and the ages of acquiring word meanings from two studies of children’s knowledge of word meanings, controlling for homographs. The agreement among these markedly different methods for determining when word meanings are understood opens up new research avenues. In addition, we have found that print frequency is associated with Word Maturity and tested knowledge of word meanings and that understanding concrete meanings required less print frequency exposure than verbally defined meanings.     

A Root Awakening: Vocabulary Instruction for Older Students with Reading Difficulties

There is reliable evidence that new vocabulary is primarily acquired through wide independent reading. However, struggling readers tend to avoid reading, resulting in limited word encounters and inadequate vocabulary growth, and they often have difficulties inferring the meanings of new words from context. While there are no clear solutions to the problem of vocabulary acquisition for older students with reading difficulties, there are instructional approaches that have some evidence of effectiveness for this population. We describe the research base and promising practices related to three aspects of vocabulary instruction: (1) creating a verbal learning environment that fosters word consciousness, (2) selecting and teaching specific words, and (3) teaching an independent word learning strategy through a combination of contextual and morphemic analysis. These instructional approaches are grounded in overarching principles recognized by researchers as being characteristic of effective instruction for students with learning difficulties, including explicit instruction, promoting cognitive and collaborative engagement, and providing many opportunities for practice, including distributed practice, with teacher feedback. Finally, we discuss the possibilities inherent in a cross‐content schoolwide approach to vocabulary instruction at the secondary level. We conclude with a call for additional research examining the effectiveness of instructional approaches to vocabulary development for secondary school students with reading difficulties, including a schoolwide collaborative model.     

Unraveling Vocabulary Learning: Reader and Item-Level Predictors of Vocabulary Learning Within Comprehension Instruction for Fifth and Sixth Graders

This study explores reader, word, and learning activity characteristics related to vocabulary learning for 202 fifth and sixth graders (N = 118 and 84, respectively) learning 16 words. Three measures of word knowledge were used: multiple-choice definition knowledge, self-report of meaning knowledge, and production of morphologically related words. Results indicate that significant vocabulary learning occurred on each measure and that certain words were easier to learn for certain types of readers. Controlling for other predictors in the model, reader characteristics like morphological awareness, reading comprehension, and language background were significant predictors of vocabulary learning, but not word reading fluency. Also, word characteristics like morphological family size and opaqueness were significant predictors of word difficulty but not number of morphemes or frequency of the word or root-word or affix. Controlling for other predictors in the model, morphological learning activities supported vocabulary learning for all 3 aspects of word knowledge. Implications for theory and instruction are discussed.     

Examining reading comprehension text and question answering time differences in university students with and without a history of reading difficulties

The current study aimed to examine performance times during text reading and question answering of students with and without a history of reading difficulties. Forty-three university students with a history of reading difficulties (HRD) were compared to 124 university students without a history of reading difficulties on measures of word and nonword reading rate, text reading rate and comprehension, and question answering times. Results showed that students with HRD demonstrated slower word, nonword, and text reading rates than their peers, but had comparable reading comprehension scores. Results also showed that students with HRD took longer to answer specific types of questions even when reading rate was controlled. Specifically, when word reading rate was controlled, students with HRD took longer to answer vocabulary, literal, inferential, and background knowledge questions. When text reading rate was controlled, they still took longer to answer literal, inferential, and background knowledge questions. These results suggest that students with a history of reading difficulties require extra time to complete reading comprehension measures for reasons other than just slower word and text reading rate. Findings of this study have implications for supporting university students with a history of reading difficulties.     

The contributions of vocabulary and letter writing automaticity to word reading and spelling for kindergartners

In the present study we examined the relation between alphabet knowledge fluency (letter names and sounds) and letter writing automaticity, and unique relations of letter writing automaticity and semantic knowledge (i.e., vocabulary) to word reading and spelling over and above code-related skills such as phonological awareness and alphabet knowledge. These questions were addressed using data from 242 English-speaking kindergartners and employing structural equation modeling. Results showed letter writing automaticity was moderately related to and a separate construct from alphabet knowledge fluency, and marginally (p = .06) related to spelling after accounting for phonological awareness, alphabet knowledge fluency, and vocabulary. Furthermore, vocabulary was positively and uniquely related to word reading and spelling after accounting for phonological awareness, alphabet knowledge fluency, and letter writing automaticity.     

The role of reading comprehension in word meaning acquisition during reading

The purpose of this study was to explore the influence of reading comprehension on the acquisition of word meanings from context and to compare it to the effects of local context characteristics, such as proximity and directness of context clues. The study also examined the effects of prior topic and enabling concept knowledge. Sixth-grade students were pretested on their knowledge of target vocabulary from two expository passages appropriate for their grade and reading level. The students were then familiarized with selected main concepts from one passage and, subsequently, read both experimental passages. Half of the target words appeared in an informative context, while the rest appeared in an less-informative context. A comprehension test and a vocabulary posttest followed the reading of each passage. Hierarchical Regression analyses indicated that reading comprehension level and prior main concept knowledge facilitated vocabulary learning from context. In comparison, the effect of presence or absence of informative context clues was not significant. These findings, underline the need for a reconceptualization of context to take into account the mental representation that readers construct in addition to the printed text that surrounds an unfamiliar word.     

It matters whether reading comprehension is conceptualised as rate or accuracy

This study shows that it makes a difference whether accuracy measures or rate measures are used when assessing reading comprehension. When the outcome is reading comprehension accuracy (i.e., the number of correct responses), word reading skills (measured as access to orthographic representations) account for a modest amount of the variance in the reading comprehension of 10‐year old children. However, this changes when reading comprehension is conceptualised as rate (i.e., number of correct responses per minute); when this is done, the correlation with word reading increases. The result was validated in two different reading comprehension tests. Moreover, this study indicates that it is not merely efficient word reading that influences the process of comprehending at a fast rate. When word reading and receptive vocabulary are controlled, a written measure of the ability to access and connect similar word meanings (synonym judgement) explains additional variance in reading comprehension rate.     

Minding morphology: How morphological awareness relates to reading for English language learners

This study explored subprocesses of reading for 157 fifth grade Spanish-speaking English language learners (ELLs) by examining whether morphological awareness made a unique contribution to reading comprehension beyond a strong covariate-phonological decoding. The role of word reading and reading vocabulary as mediators of this relationship was also explored. Results showed that fourth grade morphological awareness did not make a significant unique direct effect on fifth grade reading comprehension, controlling for phonological decoding, word reading, and reading vocabulary. Fourth grade morphological awareness did, though, make a unique moderate total contribution to fifth grade reading comprehension with reading vocabulary, but not word reading, mediating the relationship when controlling for phonological decoding. In contrast, phonological decoding made a nonsignificant total contribution to reading comprehension with neither word reading nor reading vocabulary mediating the relationship when controlling for morphological awareness. Alternative models were also explored, showing the importance of including both predictors in a model of ELL reading comprehension, primarily to include the support of phonological decoding to word reading and the support of morphological awareness to reading comprehension via reading vocabulary. Results highlighted the importance of morphological awareness in facilitating reading comprehension via improving reading vocabulary knowledge, and also the potential of interventions involving morphological instruction to support reading achievement for Spanish-speaking ELLs.     

The role of background knowledge in text comprehension for children learning English as an additional language

Children learning English as an additional language (EAL) often experience difficulties with reading comprehension relative to their monolingual peers. While low levels of vocabulary appear to be one factor underlying these difficulties, other factors such as a relative lack of appropriate background knowledge may also contribute. Sixteen children learning EAL and 16 of their monolingual peers, matched for word reading accuracy, were assessed using a standard measure of reading comprehension and an experimental measure of reading comprehension for which relevant background knowledge was taught before assessing understanding. Tests of receptive and expressive vocabulary were also completed. Results confirmed lower levels of reading comprehension for children learning EAL for both standard and ‘background’ controlled measures. Analysis of comprehension by question type on the experimental measure showed that while both groups made use of taught knowledge to answer inferential questions, children learning EAL had specific difficulties with both literal questions and questions requiring the interpretation of a simile. It is suggested that relevant background information should be used to facilitate children's text comprehension. Furthermore, several factors, especially vocabulary differences, but also text search strategies, context use and comprehension monitoring skills, may contribute to the comprehension difficulties experienced by children learning EAL.     

Unpacking the relation between morphological awareness and Chinese word reading: Levels of morphological awareness and vocabulary

The nature of the relations among morphological awareness, vocabulary and word reading in Chinese children remains relatively unclear. The present study aimed to distinguish between sublexical morphological awareness, referring to the ability to use the meaning cues of semantic radicals embedded in a compound character, and lexical level morphological awareness, defined as the ability to understand and manipulate single characters (i.e., morphemes) comprising Chinese compound words, on word reading. We also examined the role of vocabulary knowledge on the relation between morphological awareness and word reading at both the sublexical and lexical levels. A group of 172 Chinese second graders were administered measures of sublexical and lexical level morphological awareness, vocabulary knowledge, phonological awareness, orthographic knowledge, nonverbal ability, and word reading. Both sublexical and lexical levels of morphological awareness were moderately correlated with word reading. Vocabulary knowledge appeared to partially mediate the effect of sublexical morphological awareness on word reading, but it fully mediated the effect of lexical level morphological awareness on word reading. These results suggest that sublexical and lexical level morphological awareness play distinct roles in Chinese word reading; vocabulary knowledge is an important factor influencing the relation between morphological awareness and word reading in Chinese.     

Weak and strong novice readers of english as a foreign language: Effects of first language and socioeconomic status

This study examined individual differences among beginning readers of English as a foreign language (EFL). The study concentrated on the effects of underlying first language (L1) knowledge as well as EFL letter and vocabulary knowledge. Phonological and morphological awareness, spelling, vocabulary knowledge, and word reading in Hebrew L1, in addition to knowledge of EFL letters and EFL vocabulary, were measured. The study also investigated the effect of socioeconomic background (SES) on beginning EFL readers. Participants included 145 fourth graders from three schools representing two socioeconomic backgrounds in the north of Israel. The results indicate that knowledge of English letters played a more prominent role than knowledge of Hebrew L1 components in differentiating between strong and weak EFL readers. The Linguistic Coding Differences Hypothesis was supported by L1 phonological awareness, word reading, and vocabulary knowledge appearing as part of discriminating functions. The presence of English vocabulary knowledge as part of the discriminant functions provides support for English word reading being more than just a decoding task for EFL beginner readers. Socioeconomic status differentiated the groups for EFL word recognition but not for EFL reading comprehension.     

The role of word decoding,vocabulary knowledge and meta‐cognitive knowledge in monolingual and bilingual low‐achieving adolescents' reading comprehension

In this study, we analysed the relationships between word decoding, vocabulary knowledge, meta‐cognitive knowledge and reading comprehension in low‐achieving adolescents and examined whether the strength of these relationships differed between Grade 7 and 9 students and between monolingual and bilingual students. Tests were administered to 328 students in Dutch prevocational education. Multilevel analyses showed positive effects of vocabulary and meta‐cognitive knowledge on reading comprehension that were consistent across grades and across monolinguals and bilinguals. Additionally, we found a positive effect of word decoding for seventh graders, but no effect for ninth graders. There was also a positive effect of bilingualism on reading comprehension when vocabulary differences were controlled. This finding suggests that for bilingual students, reading comprehension is hampered by limited second‐language vocabulary knowledge and that these students will profit more from an increase in vocabulary knowledge than their monolingual peers. The results underline the importance of vocabulary and meta‐cognitive instruction for low‐achieving adolescents.     

The development and application of a specialised word list: the case of Fabrication

Learners in the trades are faced with learning a large amount of technical vocabulary along with the content of their field, but they do not tend to encounter this language outside their courses of study. This technical vocabulary is a core element in their developing knowledge of their trade and their learner identity. This article focuses first on identifying technical vocabulary in Fabrication using specialised written and spoken corpora, and through extensive checking with experts in the field as well as reference sources. A technical word list of 1079 types was developed, along with a list of common abbreviations and their meanings and a list of proper nouns. The technical word list covers over 30% of the vocabulary in the written Fabrication corpus and just over 9% of the spoken Fabrication corpus. The second part of the article discusses this vocabulary in light of the concept of vocational thresholds and provides suggestions for incorporating the word list into pedagogy, including an apprenticeship approach in which a focus on literacy/literacy acquisition is embedded into content teaching. Suggestions for future research are also included.
