Morphological awareness and learning to read Chinese

This study investigated the nature of morphological awareness and its relation to learning to read Chinese characters among 46 Chinese-speaking preschool children. The children took a morphological awareness task, which varied in semantic transparency and morpheme position. Children’s vocabulary knowledge and extant character reading ability were measured. Additionally, a character learning task was administered. Results showed that children’s performances on morphological awareness were affected by semantic transparency but not by morpheme position. Morphological awareness was related to vocabulary knowledge when partialling out character reading ability but not to character reading ability after partialling out vocabulary knowledge. The results of the character learning task further revealed that morphological awareness was related to character identification in the words that were just taught but not to character identification in the words that were not taught or in pseudowords. The relation between morphological awareness and character identification ceased to be significant when partialling out the variance in children’s prior knowledge of the characters to be learnt. Taken together, the findings suggested that vocabulary knowledge may play a more important role than reading ability in the initial development of morphological awareness and that the facilitative effect of morphological knowledge in reading does not seem to be significant in the very initial stages of reading acquisition.     

Efficacy of Rich Vocabulary Instruction in Fourth- and Fifth-Grade Classrooms

A multi-cohort cluster randomized trial was conducted to estimate effects of rich vocabulary classroom instruction on vocabulary and reading comprehension. A total of 1,232 fourth- and fifth-grade students from 61 classrooms in 24 schools completed the study. Students received instruction in 140 Tier Two vocabulary words featured in two grade-level novels. Teachers were randomly assigned to either rich vocabulary (treatment) or to business as usual (control). Teachers in the treatment condition allotted 30 minutes per day to the intervention for 14 weeks. Hierarchical linear modeling revealed positive, significant treatment effects on distal and proximal measures of vocabulary and comprehension. However, average distal treatment effects were small (approximate d =.15) compared with proximal effects (approximate d = 1.24). Observations of teachers’ language arts instruction indicated that treatment teachers spent significantly more time on vocabulary and less time on comprehension instruction than did teachers in the control condition. Results support the intensity and depth of the instruction for learning the taught corpus of words, and modest transfer to global vocabulary and comprehension.     

Building Vocabulary Knowledge in Preschoolers Through Shared Book Reading and Gameplay

This study moves beyond previous investigations to examine whether an educational intervention combining shared book reading with a vocabulary game increases children's vocabulary knowledge. Four‐year‐olds (N = 44) were randomly assigned to dyads in either an intervention (shared book reading plus vocabulary review game) or comparison condition (shared book reading, after‐reading vocabulary review, and game that did not teach vocabulary). After two 30‐min sessions, results demonstrated that the intervention condition outperformed the comparison condition on measures of receptive and expressive knowledge of taught vocabulary words. Children in the intervention group who scored the lowest at pretest on the receptive measure saw the most gains in taught word knowledge. Findings suggest that combining vocabulary gameplay with shared book reading improved children's learning of the vocabulary words in comparison to a comparison group.     

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.     

The keyword method and children's vocabulary learning: An interaction with vocabulary knowledge

Fifth-grade students with either high or low levels of vocabulary knowledge were taught a list of new vocabulary words according to the mnemonic keyword method. The children were randomly assigned either to one of three keyword instructional conditions that varied in the degree of structure provided by the experimenter, or to a no-strategy control condition. All three variations of the keyword method facilitated students' vocabulary learning. Aptitude × treatment interactions involving vocabulary knowledge materialized, however, such that the degree of keyword method structure made far less of a difference for the high knowledge students than it did for the lows. In particular, when the children had to execute the dual components of the keyword method entirely on their own, low vocabulary knowledge students experienced considerably more difficulty than did highs.     

Exploring the feasibility of a classroom‐based vocabulary intervention for mainstream secondary school students with language disorder

Vocabulary knowledge has been shown to be a predictor of academic success, posing a challenge for children and young people with language disorder. Language disorder can persist into adolescence and yet there is limited evidence on how to support the vocabulary skills of adolescents with language disorder in a mainstream setting. This article describes an experimental study aimed at investigating the feasibility of a whole‐class approach to increase the understanding and use of curriculum vocabulary in adolescents with language disorder. Ten curriculum words were taught by the science teacher using a phonological‐semantic approach, and 10 matched same‐topic words were taught using routine teaching practice. Progress was made post‐intervention in word knowledge of both low‐frequency experimental and control words, with significantly greater change in knowledge of the experimental words. Most students, and the teacher, viewed the phonological‐semantic word‐learning approach favourably.     

Exploring the dimensionality of morphological knowledge for adolescent readers

This study examined the dimensionality of morphological knowledge. The performance of 371 seventh‐ and eighth‐graders on seven morphological knowledge tasks was investigated using confirmatory factor analysis. Results suggested that morphological knowledge was best fit by a bifactor model with a general factor of morphological knowledge and seven specific factors, representing tasks that tap different facets of morphological knowledge. Next, structural equation modelling was used to explore links to literacy outcomes. Results indicated the general factor and the specific factor of morphological meaning processing showed significant positive associations with reading comprehension and vocabulary. Also, the specific factor of generating morphologically related words showed significant positive associations with vocabulary, while specific factors of morphological word reading and spelling processing showed small negative relationships to reading comprehension and vocabulary. Findings highlight the complexity of morphological knowledge and suggest the importance of being cognizant of the nature of morphology when designing and interpreting studies.     

Direct and Extended Vocabulary Instruction in Kindergarten: Investigating Transfer Effects

Abstract

The purpose of this study was to investigate the efficacy of an 18-week program of direct and extended vocabulary instruction with kindergarten students on both proximal measures of target word knowledge and transfer measures of generalized language and literacy. A second purpose was to examine whether treatment effects would be moderated by initial receptive vocabulary knowledge measured at pretest. In a quasi-experimental design, 80 kindergarten students from schools serving large at-risk populations were taught the meanings of 54 vocabulary words within interactive story read alouds over 36 half-hour instructional lessons (2 lessons per week over 18 weeks). An additional 44 students served as a no-treatment control. Findings indicated that students who received vocabulary instruction outperformed controls on a measure of target word knowledge as well as measures of generalized receptive vocabulary and listening comprehension. In addition, initial receptive vocabulary was strongly related to posttest performance on all measures. Implications are discussed in relation to supporting vocabulary development in the early grades within a multitier framework of instruction and intervention.     

Teaching abstract vocabulary with the keyword method: effects on recall and comprehension

Twenty-five adolescents with learning disabilities were randomly assigned to either a keyword mnemonic condition or an experimenter-directed rehearsal condition and were individually taught 16 difficult vocabulary words, including 8 concrete and 8 abstract words. After an instructional period, students were given a test of literal recall as well as a comprehension test of their ability to apply newly acquired vocabulary words in a different context. Results indicated that mnemonically trained students outperformed control students on both abstract and concrete words, and on recall tests as well as on comprehension tests. Implications for vocabulary instruction as well as theories of learning disabilities are discussed.     

Effectiveness of Supplemental Kindergarten Vocabulary Instruction for English Learners: A Randomized Study of Immediate and Longer-Term Effects of Two Approaches

Abstract

A two-cohort cluster-randomized trial was conducted to estimate effects of small-group supplemental vocabulary instruction for at-risk kindergarten English learners (ELs). Connections students received explicit instruction in high-frequency decodable root words, and interactive book reading (IBR) students were taught the same words in a storybook reading context. A total of 324 EL students representing 24 home languages and averaging in the 10th percentile in receptive vocabulary completed the study (Connections n = 163 in 75 small groups; IBR n = 161 in 72 IBR small groups). Although small groups in both conditions made significant immediate gains across all measures, Connections students made significantly greater gains in reading vocabulary and decoding (d =.64 and.45, respectively). At first-grade follow-up, longer-term gains were again greater for Connections students, but with smaller effect sizes (d =.29 and.27, respectively). Results indicate that explicit Connections instruction features designed to build semantic, orthographic, and phonological connections for word learning were effective for improving proximal reading vocabulary and general decoding; however, increases in root word reading vocabulary did not transfer to general vocabulary knowledge.     

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.     

Vocabulary knowledge and morphological awareness in Chinese as a heritage language (CHL) reading comprehension ability

This study explored the role of vocabulary knowledge and morphological awareness in reading comprehension ability of Chinese as a heritage language (CHL) learners. One hundred ninety five CHL students participated in this study and completed a series of measures including two sets of vocabulary knowledge (one consisting of items pertaining to early exposure to spoken Chinese and the other comprised of items selected from a pool of words in Chinese as a foreign language classrooms), morphological awareness (structural awareness and functional awareness), and reading comprehension ability (lexical inference and passage comprehension). Drawing upon structural equation modeling with a bootstrap estimation method, the study found that vocabulary knowledge and morphological awareness both contributed to reading comprehension among CHL learners. More critically, the results indicated that morphological awareness mediated the relation between vocabulary knowledge and reading comprehension in CHL learners. Furthermore, multiple regression analyses probed the relative contributions of vocabulary knowledge measures to morphological awareness and reading comprehension, and found that vocabulary knowledge acquired in formal Chinese instruction contributed to morphological awareness and reading comprehension, to a greater extent, than that gained through early exposure to spoken Chinese.     

Improving the Acquisition of Novel Vocabulary Through the Use of Imagery Interventions

The purpose of this study was to investigate the impact of imagery interventions on the vocabulary acquisition abilities of second grade students. A total of 15 students were randomly assigned to three different intervention conditions: Word Only, which involves the simple verbal presentation of a vocabulary word; Dual Coding, in which a picture was paired with the vocabulary word, and Image Creation, in which students were told to create a mental picture of the vocabulary word in their mind and draw it on paper. These students were taught a total of 21 vocabulary words: seven animal and habitat words, seven musical instrument terms, and seven science terms. A Latin square design was used, in which each group of students rotated through each of the interventions, being exposed to a different treatment condition for each category of words. Participants were measured on the number of words they were successfully able to acquire through the use of experimenter designed comprehension measures. While no statistical significance was shown between the interventions across the word categories, a significant difference was found between the Image Creation and Word Only interventions within the science terms category. Students also reported that the imagery interventions facilitated the ease with which they learned the words. The findings have implications for increasing the success of classroom instruction, specifically for presenting novel vocabulary words to early elementary learners using imagery methods.     

Comparing Effects of Instruction on Word Meaning and Word Form on Early Literacy Abilities in Kindergarten

Research Findings: The present study compared effects of explicit instruction on and practice with the phonological form of words (form-focused instruction) versus explicit instruction on and practice with the meaning of words (meaning-focused instruction). Instruction was given via interactive storybook reading in the kindergarten classroom of children learning Dutch. We asked whether the 2 types of instruction had different effects on vocabulary development and 2 precursors of reading ability—phonological awareness and letter knowledge—and we examined effects on these measures of the ability to learn new words with minimal acoustic-phonetic differences. Learners showed similar receptive target-word vocabulary gain after both types of instruction, but learners who received form-focused vocabulary instruction showed more gain in semantic knowledge of target vocabulary, phonological awareness, and letter knowledge than learners who received meaning-focused vocabulary instruction. Level of ability to learn pairs of words with minimal acoustic-phonetic differences predicted gain in semantic knowledge of target vocabulary and in letter knowledge in the form-focused instruction group only. Practice or Policy: A focus on the form of words during instruction appears to have benefits for young children learning vocabulary.     

Contribution of morphological awareness and lexical inferencing ability to L2 vocabulary knowledge and reading comprehension among advanced EFL learners: testing direct and indirect effects

Within the Structural Equation Modeling framework, this study tested the direct and indirect effects of morphological awareness and lexical inferencing ability on L2 vocabulary knowledge and reading comprehension among advanced Chinese EFL readers in a university in China. Using both regular z-test and the bootstrapping (data-based resampling) methods, the study found that morphological awareness contributed to L2 vocabulary knowledge directly and indirectly through the mediation of learners’ lexical inferencing ability. It was also observed that morphological awareness made no significant unique or direct contribution to reading comprehension after adjusting for vocabulary knowledge; its indirect effects on reading comprehension, however, were significant, both through the mediation of vocabulary knowledge alone, and the multiple mediations of lexical inferencing ability and vocabulary knowledge.     

Effects of a Supplemental Vocabulary Program on Word Knowledge and Passage Comprehension

Abstract

A cluster randomized trial estimated the effects of a supplemental vocabulary program, Elements of Reading®: vocabulary on student vocabulary and passage comprehension in moderate- to high-poverty elementary schools. Forty-four schools participated over a period spanning 2 consecutive school years. At baseline, 1,057 teachers and 16,471 students from kindergarten, first, third, and fourth grade participated. The schools were randomly assigned to either the primary or intermediate grade treatment group. In each group, the nontreatment classrooms provided the control condition. Treatment classrooms used the intervention to supplement their core reading program, whereas control classrooms taught vocabulary business-as-usual. The intervention includes structured, weekly lesson plans for 6 to 8 literary words and aural/oral and written language activities providing multiple exposures and opportunity for use. Hierarchical linear modeling was used to estimate both proximal (Year 1) and distal (Year 2) effects on vocabulary and passage comprehension. The intervention had positive and statistically significant proximal effects but no statistically significant distal effects. The results indicate that the intervention can improve targeted vocabulary and local passage comprehension, but expecting global effects may be overly optimistic.     

Derivational morphology and spelling in dyslexia

This exploratory study aimed to evaluate the spelling of derived words by dyslexic adolescents and to verify whether this is associated with lack of vocabulary and/or morphological knowledge. A cross-sectional reading level-design was employed in order to determine differences in spelling, derivational morphology and vocabulary tasks between dyslexic students aged 13+ and age-matched and reading level matched control groups. The study confirmed a profound spelling impairment of dyslexic students in comparison with two control groups but this was not associated with poor vocabulary in relation with their age-peers. In contrast, they exhibited lower levels of morphological knowledge than age-matched controls but equivalent with the reading level controls. These results are interpreted in the light of current developmental models of spelling that support a reciprocal interaction between spelling and metamorphology.     

Analysis of Malay word structure by pre-service special education teachers: foundation-level knowledge for remedial instruction

Pre-service special educators' Malay word structure knowledge was assessed through their analysis of words. A total of 69 participants analysed a vocabulary list based on a set of criteria formulated from the Malay language word structure. Results indicated that they were able to count syllables and phonemes, and identify types of affixations; however, they were unable to identify syllabic structures and word categories accurately. The morphemic and phonetic structure of words also had a moderating effect on their analysis of syllabic structures. The results implied that pre-service teachers of a transparent language still needed explicit instruction in grapheme–phoneme skills, phonic skills, morphological structure and word categories, but less instruction on phonological structure.     

Augmented Reality for Teaching Science Vocabulary to Postsecondary Education Students With Intellectual Disabilities and Autism

The purpose of this study was to examine the use of an emerging technology called augmented reality to teach science vocabulary words to college students with intellectual disability and autism spectrum disorders. One student with autism and three students with an intellectual disability participated in a multiple probe across behaviors (i.e., acquisition of science vocabulary words) design. Data were collected on each student's ability to define and label three sets of science vocabulary words (i.e., bones, organs, and plant cells). The results indicate that all students acquired definition and labeling knowledge for the new science vocabulary terms. Results are discussed in the context of applying universal design principles with emerging technologies to create authentic opportunities for students with intellectual disabilities and autism spectrum disorders to learn science vocabulary.

The moderating influence of instructional intensity and word type on the acquisition of academic vocabulary in young English language learners

This study used a within-subjects design to explore two instructional conditions for developing vocabulary in second-grade Spanish-speaking English learners (ELs)—extended instruction and embedded instruction implemented during shared interactive reading. Words assigned to the extended condition were directly taught using a multifaceted approach that included visuals, bilingual definitions, examples, spelling, and partner-talk about the words’ meaning. Words assigned to the embedded condition were taught solely through brief definitions to embedded text, writing activities, and songs. In the control condition students heard the target words read aloud during shared interactive reading but without definitions or direct instruction. The study also explored the interaction between instructional condition and word type. Four types of words—abstract cognates, abstract noncognates, concrete cognates, and concrete noncognates—were randomly assigned to each condition. Nine teachers in four schools and 187 second-grade ELs participated in this within-subjects intervention, which took place in transitional bilingual classrooms. Findings indicated that across all word types, both extended and embedded instruction were more effective than the control condition in helping ELs acquire vocabulary. Findings also indicated that extended instruction was more effective then embedded instruction for all word types except concrete cognates suggesting that these young Spanish-speaking ELs were advantaged by word knowledge in their home language. Finally, while embedded instruction was less effective than extended instruction, it was much more effective than a control condition. Embedded instruction takes significantly less preparation and instructional time than extended instruction, offering teachers a practical way to teach more vocabulary to ELs.
