RESUMO

PURPOSE: There is limited research on the writing of young Spanish-English bilinguals and their writing in both languages. In the current study, we addressed whether written syntax features differed by language (English and Spanish) and varied as a function of grade level, English learner status, and instructional program (dual or English immersion). We also examined whether Spanish and English syntax features were related cross-linguistically and related to writing quality within languages and whether these relations to writing quality were moderated by grade level, English learner status, and instructional program. METHOD: We examined written syntax features of Spanish and English essays by simultaneous and emergent bilinguals in Grades 1, 2, and 3 in either Spanish-English dual immersion or English immersion instruction in the United States (N = 278). Essays were scored for quality and evaluated for mean length of T-units, number of verbs, number of noun agreement words, and number of subject agreement words accurately conjugated. RESULTS: Written syntax features significantly differed by language and varied as a function of grade level, English learner status, and instructional program. Grades 2 and 3 wrote longer utterances, more verbs, and greater noun agreement accuracy than Grade 1. Syntax features were related to writing quality within languages, but Spanish relations were weaker for English learners than non-English learners and for dual immersion students than English immersion students. CONCLUSION: Our findings suggest written syntax features may be useful for evaluation of English-Spanish simultaneous and emergent bilinguals' writing.

RESUMO

Purpose: A large body of literature showed that word reading and listening comprehension-two proximal predictors of reading comprehension according to the simple view of reading-are related. Grounded on the direct and indirect effects model of reading (Kim, 2020a, 2020b, 2023), we examined the extent to which the relation is explained by domain-general cognitions or executive functions (working memory and attentional control) and emergent literacy skills (language and code-related skills including morphological awareness, phonological awareness, orthographic pattern recognition, letter naming fluency, and rapid automatized naming). Method: Data were from English-speaking children in Grade 1 (N = 372; 52% boys; 60% White children, 26% African American children, 6% multiracial children, 6% Hispanic children, and 2% Asian American children). Results: Results from structural equation models showed that word reading and listening comprehension were moderately related (.54). When working memory and attentional control were included as predictors, the relation became weaker (.39). When morphological awareness was additionally included, they were no longer related (.05). The other emergent literacy skills did not add explanatory power beyond executive functions and morphological awareness. Conclusion: These results indicate that executive functions and morphological awareness largely explain the shared variance between word reading and listening comprehension for English-speaking beginning readers.

RESUMO

We examined the dimensionality of oral discourse skills (comprehension and retell of texts) and the relations of language and cognitive skills to the identified dimensions. Data were from 529 English-speaking second graders (Mage = 7.42; 46% female; 52.6% Whites, 33.8% African Americans, 4.9% Hispanics, 4.7% two or more races, .8% Asian Americans, .6% American Indians, .2% Native Hawaiians, 2.5% unknown; data from 2014-2015 to 2016-2017). Confirmatory factor analysis revealed that oral discourse skills are best described as four related but dissociable dimensions of narrative comprehension, narrative retell, expository comprehension, and expository retell (rs = .59-.84). Language and cognitive skills had different patterns of relations to the identified dimensions and explained larger amounts of variance in comprehension than in retell.

RESUMO

PURPOSE: Children's ability to adjust one's language according to discourse context is important for success in academic settings. This study examined whether second graders vary in linguistic and discourse features depending on discourse contexts, that is, when describing pictures in contextualized (describing the picture to an examiner while looking at it together) and decontextualized (pretending to describe the picture to a friend while sitting in front of the examiner) conditions. METHOD: A total of 330 English-speaking second graders in the United States (M age = 7.33 years; 53% boys; 55% Caucasian children, 35% African American children) described three pictures in contextualized and decontextualized conditions. Children's picture descriptions were transcribed verbatim and coded for linguistic (e.g., elaborated noun phrase) and discourse (e.g., proper character introduction, degree of decontextualization) features. RESULTS: Type-token ratio was higher in the contextualized condition than in the decontextualized condition, whereas certain types of elaborated noun phrases (e.g., simple descriptive noun phrase, noun phrase with postmodification), coordinating conjunctions, and nonclauses occurred more frequently in the decontextualized condition, controlling for total productivity and student demographics. The proportion of proper character introduction was higher in the decontextualized condition, whereas higher degrees of decontextualization and complex perspective-taking were found in the contextualized condition. CONCLUSION: Various linguistic and discourse cues illustrated the extent to which primary grade students employ their discourse knowledge when producing oral language.

RESUMO

Eye movements provide a sensitive window into cognitive processing during reading. In the present study, we investigated beginning readers' longitudinal changes in temporal and spatial measures of eye movements during oral versus silent reading, the extent to which variation in eye movements is attributable to individual differences and text differences, and the functional form of growth trajectories of eye-movement variables. Data were from 363 English-speaking children (52% male; 59.8% White) in the US who were followed longitudinally from Grade 1 to Grade 3. Results showed a rapid decrease in temporal eye-movement measures (e.g., first fixation) and an increase in spatial eye-movement measures (initial landing position) in both oral and silent reading. The majority of variance in eye movements was attributable to individual differences whereas some variance in initial landing position was due to text differences. Most eye-movement measures had nonlinear growth trajectories where fast development tapered off near the end of Grade 3 while initial fixation count and total gaze count in silent reading had a linear growth trajectory. The findings provide a first large-scale look into the developmental progression of eye movements during oral and silent reading during a critical period when reading skills rapidly develop.

RESUMO

In this study, we examined burst length and its relation with working memory, attentional control, transcription skills, discourse oral language, and writing quality, using data from English-speaking children in Grade 2 (N = 177; M age = 7.19). Results from structural equation modeling showed that burst length was related to writing quality after accounting for transcription skills, discourse oral language, working memory, and attentional control. Burst length completely mediated the relations of attentional control and handwriting fluency to writing quality whereas it partially mediated the relations of working memory and spelling to writing quality. Discourse oral language had a suppression effect on burst length but was positively and independently related to writing quality. Working memory had an indirect relation to burst length via transcription skills whereas attentional control had a direct and indirect relation. These results suggest roles of domain-general cognitions and transcription skills in burst length, and reveal the nature of their relations to writing quality.

RESUMO

We examined the relation between reading prosody and reading comprehension, using a systematic review and meta-analysis to estimate the strength of the relation and to understand whether the strength of the relation varies by prosody feature (adult-like contour, F0 sentence-final declination, grammatical pauses, ungrammatical pauses, prosody scale), students' developmental phase of reading skill as examined by grade level, and orthographic depth. A total of 35 studies (K = 98; N = 9,349; Grades 1-9, 8 languages) met inclusion criteria. Overall a moderate relation (.51) was found between reading prosody and reading comprehension. Furthermore, the strength varied by prosody feature such that the relation was stronger for prosody rating scale than for pitch indicators such as adult-like contour and F0 sentence-final declination. However, grade and orthographic depth were not significant moderators. These results suggest that the relation between reading prosody and reading comprehension is not unitary and should consider specific aspects of reading prosody.

RESUMO

We investigated the dimensionality and relations between L1 and L2 writing skills in narrative and informational genres, and higher order cognitive skills-inference, perspective taking, and comprehension monitoring-for Spanish-English dual language learners in primary grades. Dimensions of written composition and higher order cognitive skills were examined, comparing nine alternative models. Data from 317 dual language learners in Grades 1 and 2 were used in confirmatory factor analysis and structural equation modeling. For the dimensionality of written composition, a unidimensional model, where writing was characterized as a single underlying construct across languages (Spanish and English) and genres (narrative & opinion), fit the data best. With regard to the dimensionality of higher order cognitive skills, data supported a bifactor model with (a) a general factor that captures common variance across languages and across inference, perspective taking, and comprehension monitoring skills and (b) specific factors by language (Spanish and English). The higher order cognition general factor was fairly strongly related to writing quality (.59), and the relation remained even after accounting for sex, poverty status, grade level, English learner status, school, and biliterate status. These relations were similar for students in English immersion program and Spanish-English dual immersion programs. These results indicate potential cross-language transfer of higher order cognitive skills, and the roles of higher order cognitions in written composition for Spanish-English dual language learners.

RESUMO

This article presents the application of the interactive dynamic literacy (IDL) model (Kim, 2020b) toward understanding difficulties in learning to read and write. According to the IDL model, reading and writing are part of communicative acts that draw on largely shared processes and skills as well as unique processes and skills. As such, reading and writing are dissociable but interdependent systems that have hierarchical, interactive, and dynamic relations. These key tenets of the IDL model are applied to the disruption of reading and writing development to explain co-occurrence of reading-writing difficulties using a single framework. The following hypotheses are presented: (a) co-occurrence between word reading and spelling and handwriting difficulties; (b) co-occurrence of dyslexia with written composition difficulties; (c) co-occurrence between reading comprehension and written composition difficulties; (d) co-occurrence of language difficulties with reading difficulties and writing difficulties; (e) co-occurrence of reading, writing, and language difficulties with weak domain-general skills or executive functions such as working memory and attentional control (including attention-deficit/ hyperactivity disorder [ADHD]); and (f) multiple pathways for reading and writing difficulties. Implications are discussed.

RESUMO

We examined the relations of inference, vocabulary, decoding, short-term memory, and attentional control to reading comprehension and mathematics performance for first-grade students in the US (N = 83). The students were composed of 75% Hispanics, 15% Whites, and 6% Asian Americans. Students' performance on mathematics and reading comprehension were very strongly related (r = 0.88). Results from path analysis showed that inference (0.27 ≤ s ≤ 0.38) was independently and positively related to both reading comprehension and mathematics performance after accounting for short-term memory, attentional control, decoding, and vocabulary. Decoding was independently related to reading comprehension, but not mathematics, whereas vocabulary was independently related to mathematics, but not to reading comprehension. Attentional control was directly related to mathematics, and indirectly related to reading comprehension and mathematics via inference, vocabulary, and decoding, with a substantial total effect on reading comprehension and mathematics (0.56 respectively). Short-term memory was not directly nor indirectly related to reading comprehension and mathematics. Overall these results show that language and cognitive skills are shared resources of reading comprehension and mathematics, and highlight the roles of attentional control and inference skill in reading comprehension and mathematics.

RESUMO

Perspective taking, one's knowledge of their own mental and emotional states and inferences about others' mental and emotional states, is an important skill for writing development. In the present study, we examined how perspective taking is expressed in writing and how it is related to overall writing quality. We analyzed seventh graders' source-based analytical essays (N = 195) to investigate (1) the extent to which students incorporated perspective taking in their essays, (2) how the extent of perspective taking in essays differ by students' sex and English learner status, and (3) the extent to which perspective taking in writing is associated with overall writing quality. Findings revealed that students wrote more from their own perspective than that of others. Moreover, the results of multi-level analyses suggested that female students exhibited more varied perspectives but there was no meaningful difference by English learner status. Lastly, greater extent of perspective taking, particularly that of higher level of perspectives (i.e., dual perspective), was associated with better writing quality, after accounting for students' demographic backgrounds (e.g., sex, poverty status, English learner status) and essay length. These results underscore the importance of writing from multiple perspectives on writing quality.

RESUMO

Text reading fluency refers to the ability to read connected texts with accuracy, speed, and expression (prosody), and has garnered substantial attention as an important skill for reading comprehension. However, two fundamental questions remain-the dimensionality of text reading fluency including text reading efficiency (accuracy and speed) and reading prosody, and the directionality of the relation between text reading fluency and reading comprehension. These questions were addressed using longitudinal data from Grade 1 (Mage = 6.36 years) to Grade 3 (Mage = 8.34 years). Majority of children were White (approximately 60%) and African American (26%) with 39% to 52% from low-SES backgrounds, depending on the grade. Text reading fluency, word reading, listening comprehension, and reading comprehension were measured. Results from confirmatory factor analysis revealed that text reading fluency is a multidimensional construct with a trifactor structure, which has a general factor that captures common ability across text reading efficiency and reading prosody as well as local and specific factors that are unique beyond the general factor. However, the general factor was the most reliable factor, whereas local and specific factors were not reliable. The directionality of the relation between text reading fluency and reading comprehension was addressed by examining two competing structural equation models-text-reading-fluency-as-a-predictor/mediator model and text-reading-fluency-as-an-outcome model-and data supported the former. These results indicate that text reading fluency is a multidimensional construct, and it acts as a predictor, mediating the relations of word reading and listening comprehension to reading comprehension.

RESUMO

We investigated the relations among theory of mind (ToM), mental state talk, and discourse comprehension. Specifically, we examined the frequency of mental state talk in children's oral recall of narrative texts and informational texts as well as relations among ToM, mental state talk (inclusion of mental state words in the recall of narrative and informational texts), and narrative and informational text comprehension. Results from children in Grade 4 (N = 132; Mage = 10.39 years) revealed that a greater number of mental state talk instances appeared in children's recall of narrative texts than in their recall of informational texts, but the mean number also differed across texts within a genre. ToM skill predicted the extent of mental state talk in narrative texts and informational texts, and the relation was stronger for narrative texts than for informational texts, after accounting for vocabulary, grammatical knowledge, working memory, and attentional control. Mental state talk in narrative texts was extremely strongly related to narrative comprehension, whereas mental state talk in informational texts was weakly related to informational text comprehension. Results suggest that ToM skill relates to mental state talk in the recall of texts, and both ToM and mental state talk play greater roles in comprehension of narrative texts than in comprehension of informational texts.

RESUMO

Retell is used widely as a measure of reading comprehension. In this meta-analysis, we evaluated the relation between retell and other measures of reading comprehension among students in Grades 1-12. Data from 23 studies (82 effect sizes; N = 4,705 participants) showed a moderate relation between retell and other measures of reading comprehension, r = .46. Moderation analyses revealed that the relation was stronger when reading comprehension was measured by cloze or maze tasks than when measured using a multiple-choice format. In addition, the relation was weaker in higher grades, but this was largely explained by text genre or the number of prompts in retell. The relation between 'oral' retell and reading comprehension was stronger with a greater number of prompts provided during retell tests. In contrast, results did not differ by other features of retell such as reading mode (oral or silent), text genres of retell (narrative or informational), or use of different oral retell evaluation methods (e.g., number of words or ideas, overall quality). Overall, the results indicate a moderate relation, on average, between retell and other measures of reading comprehension. However, the moderate magnitude indicates caution for using retell as the sole measure of reading comprehension. The results also indicate a need for a better understanding about more systematic approaches to retell assessment (e.g., number and kind of prompts in the case of oral retell) as a measure of reading comprehension.

RESUMO

To expand our understanding of script-general and script-specific principles in the learning of letter names, we examined how three characteristics of alphabet letters-their frequency in printed materials, order in the alphabet, and visual similarity to other letters-relate to children's letter-name knowledge in four languages with three distinct scripts (English [N = 318; M age = 4.90], Portuguese [N = 366; M age = 5.80], Korean [N = 168; M age = 5.48], and Hebrew [N = 645; M age = 5.42]). Explanatory item response modeling analysis showed that the frequency of letters in printed materials was consistently related to letter difficulty across the four languages. There were also moderation effects for letter difficulty in English and Korean, and for discriminatory power of letters in Korean. The results suggest that exposure to letters as measured by letter frequency is a language-general mechanism in the learning of alphabet letters.

RESUMO

We investigated the effect of writing interventions on written composition for students in primary grades (K-G3) with a focus on whether effects vary as a function of different dimensions of composition outcomes (i.e., quality, productivity, fluency, and other), instructional focus (e.g., transcription, self-regulation strategies such as Self-Regulated Strategy Development [SRSD]), and student characteristics (i.e., initially weak writing skills). A total of 24 studies (number of effect sizes, k = 166; N = 5589 participants) met inclusion criteria. The overall mean effect size was moderate and positive (ES = .31) with some variation across the dimensions of composition: .32 in writing quality, .31 in writing productivity, .15 in writing fluency, and .34 in writing: other. SRSD had large and consistent effect sizes across the outcomes (.59 to 1.04) whereas transcription instruction did not yield statistically significant effects on any dimensions of composition due to large variation of effects across studies. Variation in instructional dosage (total length of instruction) did not explain variation in the effect sizes. Lastly, the average effect on writing quality was larger for writers with weaker writing skills compared to those with typical skills.

RESUMO

We investigated the contributions of multiple strands of factors-individual characteristics (struggling reader status, working memory, vocabulary, grammatical knowledge, knowledge-based inference, theory of mind, comprehension monitoring), a text feature (narrative vs. expository genre), and question types (literal and inferential)-to one's performance on discourse comprehension in oral language (listening comprehension), using data from 529 second graders. Results from explanatory item response models revealed that substantial variance in listening comprehension was attributable to differences between items, texts, and children, respectively. Narrative versus expository genre distinctions explained almost all of the variance attributable to text differences. In contrast, literal versus inferential question distinctions did not explain item responses after accounting for text and reading comprehension status. However, there was a moderation between struggling reader status and question type such that struggling readers had a slightly higher (2%) probability of getting inferential questions right compared to typically developing readers, after accounting for individual and text factors. Struggling readers have a lower probability of accurate item responses than typically developing readers, but the difference disappeared once language and cognitive skills (e.g., working memory, vocabulary) were taken into consideration. The effects of text genre and question type on item responses did not differ as a function of children's language and cognitive skills. Overall, these results underscore the importance of considering individual, text, and assessment factors for children's performance in listening comprehension.

RESUMO

The authors propose an integrative theoretical model of reading called the direct and indirect effects model of reading (DIER) that builds on and extends several prominent theoretical models of reading. According to DIER, the following skills and knowledge are involved in reading comprehension: word reading, listening comprehension, text reading fluency, background knowledge (content knowledge and discourse knowledge), reading affect or socioemotions, higher order cognitions and regulation (e.g., inference, perspective taking, reasoning, and comprehension monitoring), vocabulary, grammatical (morphosyntactic and syntactic) knowledge, phonology, morphology, orthography, and domain-general cognitions (e.g., working memory and attentional control). Importantly, DIER also describes the nature of structural relations-component skills are hypothesized to have (a) hierarchical relations; (b) dynamic (or differential) relations as a function of text, activity (including assessment), and development; and (c) interactive relations. The authors then examined the hierarchical relations hypothesis by comparing a flat or direct relations model with hierarchical relations (or direct and indirect effects) models. Structural equation model results from 201 Korean-speaking first graders supported the hierarchical relations hypothesis and revealed multichanneled direct and indirect effects of component skills. These results are discussed in light of DIER, including instructional and assessment implications for reading development and reading difficulties.

RESUMO

Theory of mind has received intensive attention in research as an important skill to develop. Furthermore, recent evidence indicates its role in discourse comprehension. In the current study, we examined the mediating role of theory of mind in the relations of foundational language and cognitive skills (working memory, attentional control, vocabulary, and grammatical knowledge) to discourse comprehension using the direct and indirect effects model of text comprehension and production (Kim, 2016) as a theoretical framework, and using longitudinal data from kindergarten to Grade 2. Structural equation model results showed that theory of mind partially mediated the relations in both grades, and the effects (standardized regression weights) were similar in kindergarten and Grade 2. Interestingly, the relations of language and cognitive skills to theory of mind differed in kindergarten versus Grade 2. Language and cognitive skills had moderate to strong longitudinal stability, and these skills in kindergarten were indirectly related to discourse comprehension in Grade 2 via the language and cognitive skills in Grade 2. These results support the mediating role of theory of mind as well as the nature of structural and longitudinal relations among language and cognitive skills and to discourse comprehension.

RESUMO

BACKGROUND: Writing involves multiple processes, drawing on a number of language, cognitive, and print-related skills, and knowledge. According to the Direct and Indirect Effects model of Writing (DIEW; Kim & Park, 2019, Reading and Writing, 32, 1319), these multiple factors have hierarchical, interactive, and dynamic relations. AIMS: I examined the hierarchical relations of language and cognitive skills to written composition as well as the relation of topic knowledge to written composition, using DIEW as a theoretical framework. SAMPLE: One hundred thirty-two English-speaking students in Grade 4 were assessed on written composition, topic knowledge, oral language (vocabulary, grammatical knowledge, discourse-level oral production), higher order cognitions (inference, perspective taking [theory of mind], monitoring), domain-general cognitions (working memory and attention), and transcription skills (spelling and handwriting fluency). METHODS: Structural equation modelling was used to compare hierarchical relations models with a direct or flat relations model. RESULTS: The hierarchical relations model was supported. Discourse oral language skills and transcription skills completely mediated the relations of the other component skills to written composition, and the included component skills explained 82% of variance in written composition. Substantial total effects were found for discourse language, transcription, attention, working memory, vocabulary, theory of mind, and grammatical knowledge. Topic knowledge was moderately related to writing, but this relation became weak once the other skills were accounted for. CONCLUSIONS: Component skills have hierarchical structural relations and make direct and indirect contributions to written composition. Furthermore, the role of topic knowledge in written composition appears constrained by language and transcription skills for developing writers.
