Analytical writing poses particularly challenging, yet often overlooked, language demands that need attention in educational research and practice. In this article, I discuss the Core Analytical Language Skills (CALS) construct and its relevance for school reading and writing. CALS refer to the set of learners' school-relevant language resources that are of high utility to understanding analytical texts across content areas. After a brief review of the relations between mid-adolescents' language and their school reading and writing proficiencies, I offer illustrative examples of individual differences in middle-schoolers' analytical writing and CALS. I argue, on the basis of recent but extensive empirical evidence, that without understanding and addressing the immense variability in the language resources that students bring to school and the language demands of reading- and writing-to-learn tasks and texts, schools run the risk of maintaining and even exacerbating the inequalities that exist in the larger society.

In this study, we examine the unique and shared contributions of Spanish and English core academic language skills (CALS) to English reading comprehension in a population of Spanish-English dual language learners in Grades 4 and 5 (n = 165). We focus on cross-disciplinary CALS, operationalized as sets of high-utility lexical, syntactic and discourse resources prevalent in school texts. This study finds that Spanish and English CALS are positively and significantly related, and, further, that both sets of skills exert a unique positive influence on English reading comprehension. Aligned with an interpretation of linguistic interdependence between Spanish and English academic language skills, results document their cross-linguistic contribution to reading comprehension for students enrolled in educational programs that foster literacy and content learning regularly in two languages.

The National Assessment of Educational Progress (NAEP) in Reading aims to measure reading comprehension for students in the United States and to monitor progress in our education system. NAEP Reading is developed based on an assessment framework document that is periodically revised to reflect the latest understandings about reading comprehension and its assessment. A key goal of the Visioning Panel (VP) and the Development Panel (DP) charged with updating the NAEP Reading Assessment Framework for 2026 was to lay the foundation for an assessment that made progress toward greater fairness, equity, and validity. In this essay, we discuss how the Framework development process unfolded and its results. We document the unusual ways the National Assessment Governing Board ("the Board") shaped the development process. We provide evidence that a small group of Board members aimed to preserve the status quo in reading assessment by downplaying reliance on expertise and authoritative sources of research on reading, learning, and assessment and by removing attention to equity in NAEP Reading. We also discuss both successful (i.e., approved by the Board) and unsuccessful (i.e., rejected by the Board) recommendations for changes to the 2026 Framework that initially were proposed by the DP. We end by considering how, despite the efforts of the small group of Board members, we as a literacy field can improve the nature and impact of our large-scale reading assessments, and NAEP in particular.

Mid-adolescence is a period of considerable potential growth in the language for academic writing. Yet, to date, few writing studies explore language development during this period and even fewer focus on longitudinal or diverse samples. In this study, we examined the development of language skills for academic writing in a socio-economically diverse sample followed from sixth to seventh grade (n = 124). In each grade, participants wrote summaries of a science text. Subsequently, summaries were scored for writing quality (WQ) and analyzed for productive language skills (lexico-syntactic and discourse features). Participants completed a receptive academic language assessment and a test that measured reading comprehension of the source text. First, we examined if WQ or productive language skills changed over time. Next, we tested if Grade 6 productive and receptive language skills predicted Grade 7 WQ. Results revealed syntactic growth over time. Grade 6 use of connectives and receptive language skills emerged as predictors of Grade 7 WQ.

Recently a novel instrument -- the Core Academic Language Instrument (CALS-I) -- aimed at testing a constellation of school-relevant English language skills was developed and validated for use in the United States (Uccelli, Barr, Dobbs, Galloway, Meneses and Sánchez, 2015. Core Academic Language Skills: An expanded operational construct and a novel instrument to chart school-relevant language proficiency in preadolescent and adolescent learners. "Applied Psycholinguistics" 36: 1077-1109). The unitary construct tested by the CALS-I was dubbed Core Academic Language Skills (CALS) and it aimed to identify and describe a set of skills that comprise academic language proficiency of high utility across curricular content areas. This study piloted a version of the CALS-I that was slightly modified for use in South Africa targeting specifically middle-school learners. The results of this study reveal that the CALS construct functions almost identically to the United States sample when tested in South Africa, and this provides strong evidence for the fundamental and cross-cutting nature of these pedagogically relevant skills.

In this cluster randomized control trial study, the authors explored the efficacy of an intervention designed to improve second-grade English learners' knowledge of challenging, high-utility English vocabulary. The authors also examined whether the intervention had a differential effect on content words that differ on two attributes (cognate status and abstractness designation) and whether the effects lasted across time. Within schools, teachers were randomly assigned to treatment or control conditions, resulting in 12 treatment classrooms and 10 control classrooms. Teachers in the treatment condition developed vocabulary using six methods: interactive shared reading, direct instruction of individual words, instruction in cognate use, activities to foster word consciousness and reinforce instructed words, and use of visual and linguistic supports. Teachers in the control condition read the same books with the target vocabulary inserted into the stories. Findings on the curriculum-based and standardized measure of vocabulary indicated that the intervention implemented for four 50-minute lessons per week for 18 weeks was effective in helping English learners acquire challenging high-utility school-relevant vocabulary (Cohen's d = 1.88 for content words; d = 0.41 for connecting words; d = 0.47 for the Test of Oral Language Development). The effects differed by word characteristics, with higher effect sizes for words that are noncognates (d = 1.57 for both concrete and abstract noncognates; d = 1.02 concrete cognates; d = 0.81 for abstract cognates). Ten months after the intervention, treatment students still outperformed control students on content vocabulary learned during the intervention (d = 1.31). This study helps validate a multifaceted approach to vocabulary intervention and research.

Academic language skills support mid-adolescents' comprehension of the language of school texts. To date, scarce research has explored associations between dual academic language skills and reading comprehension among mid-adolescent dual language immersion (DLI) students. This study examined individual differences in Spanish and English academic language skills and their contribution to English reading comprehension in a cross-sectional sample of DLI students in Grades 4-6 (N = 101). Taking advantage of a recently proposed construct, the core academic language skills (CALS), and the CALS instruments available in Spanish and English, dual academic language skills were examined as predictors of English reading comprehension. Results revealed that Spanish and English CALS were both significant predictors of English reading comprehension even after accounting for students' sociodemographic background, English proficiency designation, and English word reading fluency. Findings underscore the cross-linguistic contribution of Spanish academic language skills to English reading comprehension and highlight the importance of promoting these skills in both languages to support mid-adolescent DLI students' biliteracy development.

Two widely studied language skills in relation to reading comprehension are listening comprehension skill and academic language proficiency. Although their constituent skills and theoretical accounts of how they are related to reading comprehension share a large overlap, they have been studied in separate lines of work. In this study, we investigated the dimensionality of listening comprehension and academic language proficiency tasks, their relations to reading comprehension, and the impact of assessment modality (reading vs. oral language) of academic language proficiency, using data from children in Grade 2 (N = 350). Two cohorts of children from the same schools were assessed on the same set of listening comprehension, word reading, reading comprehension, and academic language tasks. Whereas the first three constructs were assessed in identical manner across the 2 cohorts, academic language tasks were assessed in different modalities (1 cohort in a reading context and the other cohort in an oral language context). Academic language proficiency and listening comprehension skill tasks were best described as having a general oral language construct that captured common variance among all the tasks as well as having specific residual factors. Students' average performance on academic language tasks was lower in the reading context, wherein students' reading skill was also captured beyond the academic "language" proficiency. Across assessment modalities, it was the general oral language construct, not the specific factors, that was reliable, and consistently and most dominantly related to reading comprehension after accounting for word reading.

Merging evidence from psychological models of reading comprehension, ethnographic research on language and literacy, and textual linguistics lines of research, the authors take the position that psychological models of reading comprehension often overlook written language comprehension and production as context-embedded, sociocultural processes. Using the example of academic language comprehension by middle grade learners, the authors present a series of studies that have informed the science of reading by making visible a precise set of high-utility academic language skills that support informational text comprehension during middle childhood (ages 9-14). Studies have suggested that these skills develop gradually throughout adolescence and significantly contribute to reading comprehension. Drawing on this research with the goal of informing the science of reading, the authors suggest that academic language comprehension involves for the reader (a) familiarity with a set of academic language forms commonly found in school texts, (b) experience with the sociocultural practices of understanding and using the academic language of text within a particular sociocultural community, and (c) aligning with or resisting the reader identities implied by the language of a text. The authors suggest that innovative research and pedagogical approaches are needed to broaden the conceptualization of language and reading comprehension relations from purely cognitive into one that embraces the reader's interaction with a text as a sociocultural phenomenon.

This study examines the relationships between school processes and literacy in public schools that serve low-income families in a midsize city in Colombia. We focus on four categories of school processes: instructional practice; school-community engagement; well-being of students, teachers, and parents; and community belonging. We present two key results. First, we find considerable variation in literacy performance across schools, despite serving students with similar family background characteristics. Second, we find community belonging to be the most salient school process for predicting literacy. Among measures of community belonging, higher levels of students' sense of belonging and lower levels of bullying were associated with higher literacy. This study contributes to the field of international and comparative education by highlighting the importance of relational and interpersonal dimensions of school processes for children's learning. Our study also demonstrates the value of adopting an interdisciplinary lens that combines economics, child development, and sociology to better understand the links between school processes and student learning.

Learning to use language in order to complete source-based writing tasks is a challenge for middle grade writers worthy of additional study, especially given that these tasks are increasingly common in classrooms. Here, we examined the contribution of receptive and productive cross-disciplinary academic language skills to the writing quality of middle graders' science summaries, after accounting for students' sociodemographic characteristics, their comprehension of the science source text, and general summary features (i.e., length and copy ratio). Our results suggest that the ability to produce a high-quality science summary is predominately driven by the writers' receptive academic language proficiency, comprehension of the source text and productive academic language used when writing, including text length. We contend that these results are illuminating because of the joint examination of students' productive and receptive academic language skills. In addition, this study attempts to unpack the relation between summary length and quality, identifying levels of receptive academic language skills as an important moderator. These findings have the potential to advance the current understanding of malleable factors associated with science writing proficiency, as well as with those associated with source-based writing more generally.

This study reports on the conceptualization of a new construct targeting the cross-disciplinary academic language skills most relevant to school reading comprehension, targeting the validation of the Core Academic Language Skills (CALS) Instrument, a novel assessment tool which measures this construct. Participants included Grade 4-8 monolingual English and bilingual students designated as English learners (N = 7,152) from the United States. The study investigated the dimensionality of the core academic language skills construct, the reliability and validity of the CALS Instrument, and the impact of school grade on students' performance in core academic language skills. Results revealed the assessment measure to be unidimensional and to discriminate performance by grade level. This study offers insight into the value of measuring cross-disciplinary school-relevant language proficiency, delineates skills to be targeted through instruction to support reading comprehension, and offers a tool to identify students who will benefit most from this instruction.

To assess text comprehension and concept mastery, standards-aligned measures have moved from using multiple-choice questions to using source-based writing tasks (sometimes referred to as Reading-to-Write tasks). For example, it is now common for students to be asked to read a text and then to produce a written response, often a summary or argumentative essay. While this task involves comprehension of the source text, it remains unclear the degree to which these reading-to-write tasks also tap additional skills, such as academic language proficiency, which may support or hamper the writer's ability to convey information acquired from reading. Given the lack of research focused on this question, in this study, we examined whether variability in early adolescents' Core Academic Language Skills (CALS) contributes to the quality of their written summaries of science source texts. A total of 259 participants in grades four to eight were administered the "Core Academic Language Skills Instrument (CALS-I)" and the "Global Integrated Scenario-Based Assessment (GISA)," which included a reading comprehension test and a summary writing task, both based on the same scientific source text. Findings revealed that CALS, previously shown to be associated with reading comprehension, have a robust positive relation with early adolescents' science summary writing quality, predicting unique variance over and above students' source text comprehension and demographic characteristics. Results highlight the relevance of paying instructional attention not only to content but also to language skills when preparing students to become independent learners in a content area. In addition, these findings offer some evidence for CALS as a cross-modality construct relevant to both reading and writing at school.

Although many adolescents struggle to comprehend text, the school-relevant language skills, which might contribute to variation in reading comprehension ability during this developmental period, remain understudied. To expand the research base, this study examines the concurrent development of academic language skills and reading comprehension in a sample of emergent bilinguals (EBs) and their English proficient (EP) peers (n = 573) followed over two academic years, from Grade six to seven. Parallel process latent growth modeling results reveal that academic language and reading comprehension skills develop concurrently, with growth rates in Core Academic Language Skills (CALS) positively associated with growth rates in reading comprehension. Furthermore, initial levels of CALS predicted rates of growth in reading comprehension. We also find that EBs, who are by definition in the process of acquiring English, begin Grade six with CALS that are far below their peers, but develop these skills at similar rates as their EP classmates. Results reveal the potential for CALS-focused instruction for improving adolescent learners' reading comprehension development, and highlight the particular relevance of supporting CALS for EBs, who are tasked with acquiring the language of print at the same time as they are acquiring other registers of English.

This study examines whether children's decontextualized talk--talk about nonpresent events, explanations, or pretend--at 30 months predicts seventh-grade academic language proficiency (age 12). Academic language (AL) refers to the language of school texts. AL proficiency has been identified as an important predictor of adolescent text comprehension. Yet research on precursors to AL proficiency is scarce. Child decontextualized talk is known to be a predictor of early discourse development, but its relation to later language outcomes remains unclear. Forty-two children and their caregivers participated in this study. The proportion of child talk that was decontextualized emerged as a significant predictor of seventh-grade AL proficiency, even after controlling for socioeconomic status, parent decontextualized talk, child total words, child vocabulary, and child syntactic comprehension.

With a sample of 7,752 fourth- to seventh-grade students in 25 schools which were randomized at the school level to condition, this article reports experimental impacts of an enhanced version of Word Generation on student outcomes at the end of Year 1 and of Year 2. Word Generation employs analysis, synthesis, critique, and problem-solving activities to build students' academic language, perspective taking, and ultimately their reading comprehension. Results indicate that the program improves the proximate outcome of academic vocabulary included in the curriculum after the first and second year of implementation for all students (Y1 effect size (ES) = 0.22, Y2 = 0.28 for fourth and fifth graders; Y1 ES = 0.13, Y2 = 0.16 for sixth and seventh graders). For those in the fourth and fifth grades, their perspective positioning skills also improved at the end of the first year (ES = 0.14), and their academic language skills (ES = 0.06), perspective articulation and positioning skills (ES = 0.12, 0.19), and reading comprehension (ES = 0.15) improved at the end of the second year. Among sixth and seventh graders, there were improvements in perspective positioning skills (ES = 0.19) and reading comprehension (ES = 0.10) at the end of Year 2. Effects after both Years 1 and 2 were stronger in high-exposure classrooms.

Although literacy achievement has improved in Chile, adolescents' underperformance in reading comprehension is still a serious concern. In English, core academic-language skills (CALS) have been found to significantly predict reading comprehension, even controlling for academic vocabulary knowledge. CALS are high-utility language skills that support reading comprehension across school content areas. Guided by an operational definition of Spanish CALS (S-CALS), three goals drove this study: to develop two psychometrically reliable tests, the S-CALS Instrument and the Spanish Academic Vocabulary (S-AVoc) Test; to explore the dimensionality of core academic-language proficiencies, as measured by these two tests; and to examine the contribution of core academic-language proficiencies to reading comprehension. A cross-sectional sample of 810 Chilean students (grades 4-8) participated in four assessments that measured standardized reading comprehension, word-reading fluency, Spanish academic vocabulary, and S-CALS. Using classical test theory and item response theory analyses, results yielded robust reliability evidence for both instruments. Consistent with prior research, S-CALS and academic vocabulary scores displayed upward trends in higher grades yet considerable within-grade variability. Confirmatory factor analysis revealed that S-CALS and S-AVoc were best conceptualized as part of a higher order construct, the Spanish core academic-language and vocabulary skills (S-CALVS). The aggregated S-CALVS scores predicted reading comprehension, beyond the contribution of grade, school factors, and word-reading fluency. This study advances our scientific understanding of CALS as relevant for adolescent literacy beyond the English language. The high-utility school-relevant language and vocabulary skills offer promising tools to inform and evaluate innovative reading comprehension interventions for Spanish-speaking adolescents.

Educators are aware of the need to promote students' academic language to support text comprehension. Yet, besides teaching academic vocabulary, many educators continue to ask, What would this instruction entail? Guided by a new framework known as core academic language skills (CALS), the authors' research focuses on delineating core language skills that contribute to reading comprehension to make them more visible to educators and researchers. In this article, findings from two studies are integrated to argue for a mixed-methods approach to advance academic language research and pedagogy. In study 1, the authors assessed upper elementary/middle school students' CALS and quantitatively examined the association between CALS and reading comprehension. In study 2, the authors used qualitative methods to collect and analyze students' oral reflections about academic language. Key findings from these studies and their implications for academic language pedagogy in today's schools are discussed.

This study focuses on connectives, linguistic devices that signal relations between ideas. Connective knowledge varies widely across grades and is known to support reading comprehension and school writing. Despite the important role that connective knowledge plays in reading and writing, few resources exist to support teachers in understanding which connectives to prioritize in Spanish literacy instruction. In this study we combined a secondary analysis of midadolescents' connective assessment data (810 students in grades 4–8) with a corpus linguistics frequency analysis of connectives in Chilean national science and social studies textbooks (1,079,593 total words), with the goal of generating a pedagogically relevant tool to support the instruction of connectives in Spanish literacy across content areas. To generate the Connective Frequency Bands Tool, we first examined the role of grade and connective type in midadolescents' connective knowledge. Secondly, we examined associations between students' knowledge and textual frequencies across content areas for each connective included in the assessment. Finally, informed by midadolescents' connective knowledge and by the corpus linguistics analysis of science and social studies textbooks from grades 1–8, we generated the Connective Frequency Bands Tool listing connectives frequencies by grade, connective type, and content area.

"Deep reading comprehension" refers to the process required to succeed at tasks defined by the Common Core State Literacy Standards, as well as to achieve proficiency on the more challenging reading tasks in the Program for International Student Assessment (PISA) framework. The purpose of this study was to test the hypothesis that three skill domains not frequently attended to in instruction or in theories of reading comprehension--academic language, perspective taking, and complex reasoning--predict outcomes on an assessment of deep reading comprehension. The Global Integrated Scenario-based Assessment (GISA; O'Reilly, Weeks, Sabatini, Halderman, & Steinberg, 2014) is designed to reflect students' abilities to evaluate texts, integrate information from an array of texts, and use textual evidence to formulate a position, all features of deep reading comprehension. We tested the role of academic language, perspective taking, and complex reasoning in explaining variance in end-of-year GISA scores, controlling for beginning-of-year scores and student demographics. All three predictors explained small, but significant, amounts of additional variance. We suggest that these three skill domains deserve greater attention in theories of reading comprehension and in instruction.

Learning to write in middle school requires the expansion of sentence-level and discourse-level language skills. In this study, we investigated later language development in the writing of a cross-sectional sample of 235 upper elementary and middle school students (grades 4-8) by examining the use of (1) lexico-grammatical forms that support precise and concise academic writing and (2) paragraph-level structures for organizing written discourse, known as micro-genres. Writing studies typically elicit and analyze long compositions, instead the present study employed two brief writing tasks that allowed for the evaluation of language skills while minimizing the influence of topic knowledge and other non-linguistic factors. Results of structural equation modeling revealed that the two facets of language proficiency studied--lexico-grammatical skills and skill in producing paragraph-level structures (micro-genres)--represented distinguishable dimensions of productive language skill in this sample. On both dimensions, older writers (grades 6-8) demonstrated greater skill than 4th and 5th graders. These findings, which provide an initial proof of concept for the use of short writing tasks to study language skills that support academic writing, are discussed in relation to writing theory and pedagogy.

Multimodal composing is part of the Common Core vision of the twenty-first-century student. Two descriptive studies were conducted of fifth-grade students' digital folktale retellings. Study 1 analyzed 83 retellings in relation to the types and frequencies of modal use, such as image, sound, movement, and written text, as well as their retelling accuracy. Students composed within a scaffolded digital composing environment which comprised the PowerPoint authoring/presentation tool and a researcher-developed story frame. All students' retellings included writing and visual design, 80% included animation, and 70% included sound. Retelling accuracy scores averaged 54%. Study 2 was conducted with a new group of 14 fifth-grade students who had previous digital retelling experience. The retellings included the same types of modal use, but at a higher level of frequency. In their retrospective design interviews, students expressed design intentionality and a metamodal awareness of how modes work together to create an appealing story.

Despite a long-standing awareness of academic language as a pedagogically relevant research area, the construct of academic-language proficiency, understood as a more comprehensive set of skills than just academic vocabulary, has remained vaguely specified. In this study, we explore a more inclusive operationalization of an academic-language proficiency construct, core academic-language skills (CALS). "CALS" refers to a constellation of high-utility language skills hypothesized to support reading comprehension across school content areas. Using the Core Academic Language Skills Instrument (CALS-I), a theoretically grounded and psychometrically robust innovative tool, we first examined the variability in students' CALS by grade, English-proficiency designation, and socioeconomic status (SES). Then, we examined the contribution of CALS to reading comprehension using academic vocabulary knowledge, word reading fluency, and sociodemographic factors as covariates. A linguistically and socioeconomically diverse cross-sectional sample of 218 students (grades 4-6) participated in four assessments: the CALS-I, a standardized reading comprehension assessment (Gates-MacGinitie Reading Test), an academic vocabulary test (Vocabulary Association Test), and a word reading fluency test (Test of Silent Word Reading Fluency). General linear model analysis of variance revealed that CALS differed significantly by grade, English-proficiency designation, and SES, with students in higher grades, English-proficient students, and those from higher SES backgrounds displaying higher scores, on average. Hierarchical multiple regression analyses identified CALS as an independent predictor of reading comprehension, even after controlling for academic vocabulary knowledge, word reading fluency, and sociodemographic factors. By specifying a set of language skills associated with reading comprehension, this study advances our understanding of school-relevant language skills, making them more visible for researchers and educators.

Beyond mechanics and spelling conventions, academic writing requires progressive mastery of advanced language forms and functions. Pedagogically useful tools to assess such language features in adolescents' writing, however, are not yet available. This study examines language predictors of writing quality in 51 persuasive essays produced by high school students attending a linguistically and ethnically diverse inner-city school in the Northeastern United States. Essays were scored for writing quality by a group of teachers, transcribed and analyzed to generate automated lexical and grammatical measures, and coded for discourse-level elements by researchers who were blind to essays' writing quality scores. Regression analyses revealed that beyond the contribution of length and lexico-grammatical intricacy, the frequency of organizational markers and one particular type of epistemic stance marker (i.e., epistemic hedges) significantly predicted persuasive essays' writing quality. Findings shed light on discourse elements relevant for the design of pedagogically informative assessment tools. (Contains 6 tables, 1 figure and 5 notes.)

This quasi-experimental study investigated the effects of an Internet-delivered universally designed depth of vocabulary intervention that targeted both English-speaking and Spanish-English-speaking students. Two hundred forty students, 49% of whom were Spanish-English bilinguals, participated in the 16-week intervention. Intervention students read eight multimedia texts with embedded instruction on 40 words and reading strategy support. Students could access all texts and activities in Spanish and English. In comparison to a control group, there were significant intervention effects on a standardized measure of vocabulary knowledge, but effects were non-significant for comprehension. Similarly, significant effects on researcher-developed measures of vocabulary depth were detected, but not for a researcher-developed measure of breadth.

This study examined the relative contribution of reading comprehension strategies and interactive vocabulary in Improving Comprehension Online (ICON), a universally designed web-based scaffolded text environment designed to improve fifth-grade monolingual English and bilingual students' reading achievement. Seventy-five monolingual English and 31 bilingual students from six classrooms were assigned to one of three ICON conditions: reading comprehension strategies, vocabulary, or a combined version of comprehension strategies and vocabulary. Students read eight multimedia folktales and informational texts within their respective ICON condition and completed embedded activities, researcher measures of comprehension and vocabulary, and pre- and postintervention standardized reading achievement tests. ANCOVA results indicated that after controlling for initial reading achievement, there was a main effect for condition on the researcher measure of vocabulary, with the combination group and vocabulary groups both significantly outperforming the strategy group. There was also an interaction effect, with differences between monolingual and bilingual Spanish-speaking students greatest in the strategy group. There was no effect of condition on comprehension, nor was there an effect of language status on narrative comprehension. However, there was a main effect of language status on expository text comprehension and standardized vocabulary achievement, with monolingual students performing more strongly than bilingual Spanish-speaking students. The results add to a growing body of research on the design and use of scaffolded digital text for diverse learners. (Contains 6 figures and 6 tables.)

This study describes how young Spanish-speaking children become gradually more adept at encoding temporality using grammar and discourse skills in intra-conversational narratives. The research involved parallel case studies of two Spanish-speaking children followed longitudinally from ages two to three. Type/token frequencies of verb tense, temporal/aspectual markers and narrative components were analyzed to explore interrelationships among grammatical and discourse skills. Children progressed from scattered unsystematic means of encoding temporality to mastering a basic linguistic system that included devices to mark "location of events", "temporal relations" and "aspectual meanings." The consolidation of perfective past tense to express narrative events marked a crucial developmental point which preceded an explosion of additional verb tenses and temporal markers. The value of spontaneous language data, and the need to study grammar and discourse simultaneously to construct a comprehensive developmental picture are highlighted. Results are discussed in relation to theoretical proposals on the development of temporality.

The sheer quantity of words known (breadth) is strongly predictive of reading comprehension, yet little is understood about how quality of word knowledge (depth) affects comprehension. A group of 35 bilingual and monolingual 5th-grade students worked on developing depth of knowledge of 8 words, culminating in an activity in which the students produced captions for images related to each word. The captions were scored using a 4-point depth scale, and similarities and differences between bilingual and monolingual students were assessed. Results indicated a significant effect of depth of word knowledge in predicting reading comprehension, particularly for students with average to strong oral language skills. (Contains 1 footnote, 6 tables, and 1 figure.)

Narrative attainment was assessed in 76 four-year-old children at risk for brain injury because of histories of early corrective heart surgery. Despite considerable heterogeneity in narrative performance, children with early corrective heart surgery produced fewer narrative components than typically developing children. Implications for clinical assessment and possible risks for socio-emotional relationships and academic achievement are discussed. (Contains references.) (Author/DB)
