Development of decoding,reading comprehension,vocabulary and spelling during the elementary school years

The goal of this study was (1) to investigate the development of decoding(efficiency), reading comprehension, vocabulary and spelling during theelementary school years and (2) to determine the differences between poor,average and good performers with regard to the development of theseskills. Twice each year two standardized tests for each skill wereadministered. For two successive periods, one of the tests for each skill wasthe same. To describe the development in terms of a latent variable evolvingacross grades, the structured-means version of the structural equationmodel was used. The growth was expressed in terms of effect size. Withrespect to the first question, clear seasonal effects were found for readingcomprehension, vocabulary and spelling, while the seasonal effect fordecoding efficiency was restricted to the early grades. Progress tended tobe greater from fall to spring than from spring to fall. For decodingefficiency, and to a lesser degree for vocabulary and spelling, growthshowed a declining trend across grades. For reading comprehension, theprogress in grade 2 was lower than the progress in grade 3, but progresswas declining across higher grades. With respect to the second question,it appeared that initially low performers on reading comprehension,vocabulary and spelling tended to show a greater progress, especially inperiods where the largest amount of instruction was given. Although it wasfound that the low, medium and high ability groups remain in the sameorder, as far as their means are concerned, these findings do not confirmthe existence of a Matthew effect for reading comprehension, vocabularyand spelling. For decoding efficiency no clear differential effect could befound: the gap between the poor and good performers did not widen overtime for this skill.     

Expressive vocabulary development in children from bilingual and monolingual homes: A longitudinal study from two to four years

The early course of language development among children from bilingual homes varies in ways that are not well described and as a result of influences that are not well understood. Here, we describe trajectories of relative change in expressive vocabulary from 22 to 48 months and vocabulary achievement at 48 months in two groups of children from bilingual homes (children with one and children with two native Spanish-speaking parents [ns = 15 and 11]) and in an SES-equivalent group of children from monolingual English homes (n = 31). The two groups from bilingual homes differed in their mean levels of English and Spanish skills, in their developmental trajectories during this period, and in the relation between language use at home and their vocabulary development. Children with two native Spanish-speaking parents showed steepest gains in total vocabulary and were more nearly balanced bilinguals at 48 months. Children with one native Spanish- and one native English-speaking parent showed trajectories of relative decline in Spanish vocabulary. At 48 months, mean levels of English skill among the bilingual children were comparable to monolingual norms, but children with two native Spanish-speaking parents had lower English scores than the SES-equivalent monolingual group. Use of English at home was a significant positive predictor of English vocabulary scores only among children with a native English-speaking parent. These findings argue that efforts to optimize school readiness among children from immigrant families should facilitate their access to native speakers of the community language, and efforts to support heritage language maintenance should include encouraging heritage language use by native speakers in the home.

Phonological working memory: A critical building block for reading development and vocabulary acquisition?

In this article we review findings from a recent longitudinal study of the contribution of phonological working memory to vocabulary acquisition and reading development. A total of 80 children were tested initially at school entry at the age of four years, and were tested in three further waves at ages 5, 6, and 8 years. The results indicate that phonological memory skills constrain vocabulary growth during the first year or so in school but that subsequently, vocabulary knowledge is a pacemaker in the development relationship with memory. Phonological memory skill in prereading children was found to be significantly linked with scores on a reading test at age 8 which encourages the use of a phonological recoding strategy. The theoretical and practical implications of the findings, and important areas for future research, are discussed.

Self-efficacy, task complexity and task performance: Exploring interactions in two versions of vocabulary learning tasks

The present study aimed for better understanding of the interactions between task complexity and students?? self-efficacy beliefs and students?? use of learning strategies, and finally their interacting effects on task performance. This investigation was carried out in the context of Chinese students learning English as a foreign language in a university in China. The participants were 78 second-year university students (mean age?=?20.9?years). This study used a repeated-measures design with task complexity as the within-participants factor, and task sequence as the between-participants factor. Results indicated a significant task effect for self-efficacy beliefs and task performance, and a significant interaction effect of sequence with task complexity for learners?? self-efficacy beliefs in learning for both task versions, learners with higher self-efficacy beliefs had better task performances than learners with lower self-efficacy beliefs. The results also revealed a strong correlation between self-efficacy and the use of learning strategies for both tasks.     

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

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

Writing evaluation: rater and task effects on the reliability of writing scores for children in Grades 3 and 4

We examined how raters and tasks influence measurement error in writing evaluation and how many raters and tasks are needed to reach a desirable level of .90 and .80 reliabilities for children in Grades 3 and 4. A total of 211 children (102 boys) were administered three tasks in narrative and expository genres, respectively, and their written compositions were evaluated in widely used evaluation methods for developing writers: holistic scoring, productivity, and curriculum-based writing scores. Results showed that 54 and 52% of variance in narrative and expository compositions were attributable to true individual differences in writing. Students’ scores varied largely by tasks (30.44 and 28.61% of variance), but not by raters. To reach the reliability of .90, multiple tasks and raters were needed, and for the reliability of .80, a single rater and multiple tasks were needed. These findings offer important implications about reliably evaluating children’s writing skills, given that writing is typically evaluated by a single task and a single rater in classrooms and even in some state accountability systems.

Relationships of general vocabulary, science vocabulary, and student questioning with science comprehension in students with varying levels of English proficiency

This study investigated the influence of general vocabulary knowledge, science vocabulary knowledge, and text based questioning on the science reading comprehension of three types of students who varied in their English language proficiency. Specifically, grade 5 English-Only speakers, English Language Learners in the United States, and students learning English as a Foreign Language in a Spanish-speaking country were compared across the aforementioned variables to examine their relationship to reading comprehension. Findings indicated that general vocabulary, science vocabulary, and questioning contributed significant variance to the explanation of science reading comprehension. However, no particular variable was found to interact with language proficiency in their contribution to science reading comprehension. Findings are discussed in terms of the roles that each variable could play in content area comprehension. Implications for content-area literacy instruction of second-language students are considered.     

Otis-Lennon Mental Ability Test,Stanford Achievement Test,and Three Demographic Variables as Predictors of Achievement in Grades 2 and 4

Abstract

A series of multivariate statistical analyses was used to determine what relationships exist among three demographic variables, the Otis-Lennon Mental Ability Test (OLMAT), and the Stanford Achievement Test (SA T) at Grades 2 and 4. Data were obtained from the second grade classes in 1977-78 (V = 91) and 1979-80 (V = 103), and from the 1979-80 fourth grade class (/V = 91) in a rural middle income school district in southeastern New Hampshire. The best predictor of achievement at either Grade 2 or Grade 4 was the IQ variable alone. The correlations among the SAT subtests led to questions concerning that test’s construct validity and its use for differential diagnosis of educational problems of children. Among the Grade 2 variables, the best predictor of achievement at Grade 4 was the SAT; IQ was a negligible factor. Detailed study of the correlations between the OLMAT and SAT did not support the continued use of the group IQ test as part of the district’s comprehensive testing program; the costs expended cannot be justified by the value of the information obtained.     

The global growth of the International Baccalaureate Diploma Programme over the first 40 years: a critical assessment

The year 2007 was a highly significant one for ‘international education’ in an ‘internationally minded school’ context. It marked the fortieth anniversary of the first trial exam of the International Baccalaureate Diploma Programme (IBDP). This paper charts the rather random global growth of this programme, from it being a long‐awaited experiment in international education sat by 147 students in two schools, to it being a curriculum offered in 1779 schools in 128 countries. It is shown how the initially Eurocentric bias of the global spread has become a distinct North American one. At present 35% of schools can be found in the US, whilst Africa accounts for only 2%. In 38 countries there is a single school offering the programme. The wider implications of this regional disparity are explored, concluding that perhaps the programme requires a more critical and planned growth strategy.     

Spoken vocabulary growth: Its role in the development of phoneme awareness and early reading ability

In this paper, two theoretical positionsregarding the developmental origins of thephoneme as a unit for lexical representationand processing are outlined – theaccessibility and emergent positions. OurLexical Restructuring Model (Metsala & Walley1998), which is consistent with the secondposition, focuses on the role of vocabularygrowth in prompting the implementation of morefine-grained, segmental representations forlexical items in childhood; this restructuringis viewed as an important precursor to theexplicit segmentation or phoneme awarenessskills implicated in early reading success.Empirical evidence that supports this model issummarized, including preliminary results fromone of our most recent studies. Severalsuggestions are made for future research thatwill lead to a better understanding of thedevelopment of spoken word recognition and thelinks between speech- and reading-relatedabilities.     

Links among segmenting,spelling, and reading words in first and second Grades

Twenty first graders and twenty second graders were examined on skills in segmenting, reading, and spelling 50 words with regular and exceptional spelling patterns. By using the same words for each task, it was possible to assess the interrelationships among these skills on a word by word, child by child basis. A multivariate analysis of variance was conducted on difference scores among segmentation, reading, and spelling. Generally, differences favored segmentation and were maximized when final sounds were deleted and minimized when medial sounds were deleted. In addition, graphical analyses showed a greater probability of correct reading and spelling given correct segmentation than incorrect segmentation. Results were interpreted to support a computational notion of phonology as a prerequisite to reading and spelling, with a more reflective notion explaining the reciprocal relation between reading and segmentation of consonant blends and medial sounds.     

Teachers’ expectations about students’ use of reading strategies,knowledge and behaviour in Grades 3, 5 and 7

Although extensive basic research has been carried out on children’s metacognition, little is known about teachers’ views of their students’ cognitive and metacognitive skills in reading. The ways in which teachers expected their children to use, or to know how to use, certain reading skills are examined in this study. A questionnaire on reading components (strategies, knowledge and behaviour) was completed by 45 teachers in Grades 3, 5 and 7. In this questionnaire teachers were asked to make judgements about whether or not students of high, average and low ability levels in their classes would be likely to show these skills. An analysis of variance (grade×ability×component) revealed a significant interaction between ability and component. There was much greater variability in the three components for the low and average levels of ability. The main effect for ability was significant. The highest expectations of teachers were for high‐ability students in all the three groups of items, followed by average and low‐ability students. The main effect for component was also significant for knowledge. There was no significant difference between the grades. However, teachers hold equivalent performance expectations for high‐ability students in each of the three components, but for average and low‐ability groups, expectations were higher for knowledge than strategy and behaviour.

Social and emotional development in the first two years

Summary Social and emotional development begins from the moment of birth. Remarkably, infants are able to engage with their social world, particularly their parents and family. They start to establish a secure attachment with their primary caregivers who provide not only nurturance but guidance. A sense of security facilitates infants' exploration of their physical and social world. They demonstrate selective preferences—they prefer to look at faces and listen to voices—that reflect their genetically programmed disposition. Infants are able to express their emotions and recognize the emotional expressions of others. The development of basic human attributes emerge in the first few weeks and months of life. Caring, loving adults play such a critical role in providing learning opportunities to interact with others and express their emotions in an appropriate manner. Adults shape the quality of experiences that infants encounter and provide the basic building blocks of trust that support further development later in life.     

Physical and cognitive development in the first two years

Summary Physical and cognitive development proceed at a breathtaking pace in the first two years of life. Infants enter the world as competent individuals who actively explore the external world from the moment of birth. As their basic reflexes disappear, they begin to engage in intentional and purposeful behavior. Their ability to move, as in crawling and walking, and to manipulate objects extends their opportunities to learn about the physical environment. Responsive and supportive caregivers who work with infants and toddlers play a critical role in providing an optimal learning environment that takes into account infants' unique developmental needs. The next segment of the four-part series addresses the social and emotional development of infants and toddlers.
