Previous research has suggested that children in the early grades of primary school do not have much awareness of morphemes.
In this study, a priming paradigm was used to try to detect early signs of morphological representation of stems through a
spelling task presented to Portuguese children (N = 805; age range 6–9 years). Primes shared the stem with the targets and contained well-articulated, stressed vowels; the
stems of the target words and pseudo-words contained non-stressed schwa vowels, which typically result in spelling difficulties.
If priming proved effective, the well-articulated vowels in the prime should result in an improvement in the spelling of the
schwa vowels. Primes were presented in two conditions: in only-oral or in oral-plus-written form. Effectiveness of priming
was assessed by comparison with a no-priming condition. For both words and pseudowords, there was a significant interaction
between priming effects and grade. No priming effects were detected in 6- and 7-year-old children; oral-plus-written priming
produced higher rates of correct vowel spelling for 8- and 9-year-olds; only-oral priming was effective in improving the vowel
spelling of 9-year-olds. Thus older children can use morphological information under priming conditions when the prime and
the target are not phonologically transparent but there is no evidence to suggest that younger children do so. 相似文献

Phonological awareness is a strong predictor of children's progress in literacy acquisition. There are different ways of segmenting words into sound sequences – syllables, phonemes, onset-rime – and little is known about whether these different levels of segmentation vary in their contribution to reading and writing. Does one of them – for example, phoneme awareness – play the major role in learning to read and spell making the other phonological units irrelevant to the prediction of reading? Or do different levels of analysis make independent contributions to reading and spelling?
Our study investigated whether syllable and phoneme awareness make independent contributions to reading and spelling in Greek. Four measures were used: syllable awareness, phoneme awareness, reading and spelling. Analyses of variance showed that Greek speaking children found it easier to analyse words into syllables than phonemes, irrespective of the influence of task variables such as position of the phonological element, word length, and placement of stress in the word. Regression analyses showed that syllable and phoneme awareness make significant and independent contributions to learning written Greek. We conclude that phonological awareness is a multidimensional phenomenon and that the different dimensions contribute to reading and writing in Greek.

Student mastery of rational number and proportional reasoning is a recognized challenge, yet supporting mastery is central
within mathematics and science. This paper focuses on a 4-lesson teaching programme which was designed to foster mastery in
the context of intensive quantities. Intensive quantities such as density, speed and temperature depend upon proportional
relations, require rational number for their representation and are relevant to science. Two versions of the teaching programme
were developed, one using ratio representation and the other using fractions. Implementation with 535 children aged 9–11 years
revealed that both versions promoted mastery of fractions, whilst the ratio version also supported proportional reasoning.
It is suggested that the ratio version provides useful foundations for teaching, even with children who, as with the present
sample, have no previous experience of ratios themselves. 相似文献

The relation between morphological awareness and reading and spelling in Greek: a longitudinal study
The aim of this longitudinal study is to examine the contribution of morphological awareness to the prediction of reading and spelling in Greek. The target group (N = 404) consisted of children, aged 6–9 years at the start of the project, who learn literacy in Cyprus. Because there are no standardized measures of morphological awareness for Greek Cypriot children, morphological awareness measures were developed and validated. A concurrent analysis of the first wave of data collection showed that morphological awareness made a unique contribution to the prediction of reading and spelling in Greek. The longitudinal analyses showed that morphological awareness predicted performance in reading eight months later, even after partialling out grade level, verbal intelligence, phonological awareness and initial scores in reading and spelling. This study makes theoretical, empirical and practical educational contributions. It shows the long term and specific relation of morphological awareness with reading in Greek and establishes the plausibility of a causal link between morphological awareness and reading, which must be tested in further research using intervention methods. In practice, this study contributes valid measures for assessing morphological awareness in Greek as well as a new measure of spelling skill. 相似文献

The basis of this intervention study is a distinction between numerical calculus and relational calculus. The former refers
to numerical calculations and the latter to the analysis of the quantitative relations in mathematical problems. The inverse
relation between addition and subtraction is relevant to both kinds of calculus, but so far research on improving children’s
understanding and use of the principle of inversion through interventions has only been applied to the solving of a + b − b = ?
sums. The main aim of the intervention described in this article was to study the effects of teaching children about the explicit
use of inversion as part of the relational calculus needed to solve inverse addition and subtraction problems using a calculator.
The study showed that children taught about relational calculus differed significantly from those who were taught numerical
procedures, and also that effects of the intervention were stronger when children were taught about relational calculus with
mixtures of indirect and direct word problems than when these two types of problem were given to them in separate blocks. 相似文献

Multiplicative reasoning is required in different contexts in mathematics: it is necessary to understand the concept of multipart units, involved in learning place value and measurement, and also to solve multiplication and division problems. Measures of hearing children's multiplicative reasoning at school entry are reliable and specific predictors of their mathematics achievement in school. An analysis of deaf children's informal multiplicative reasoning showed that deaf children under-perform in comparison to the hearing cohorts in their first two years of school. However, a brief training study, which significantly improved their success on these problems, suggested that this may be a performance, rather than a competence difference. Thus, it is possible and desirable to promote deaf children's multiplicative reasoning when they start school so that they are provided with a more solid basis for learning mathematics. 相似文献

Our past research identified two aspects of deaf children's functioning that places them at risk for underachievement in mathematics. The first is their reduced opportunities for incidental learning, and the second is their difficulty in making inferences involving time sequences. This article examines the effectiveness of an intervention program to promote deaf children's numeracy that was designed to deal with these two factors. The design involved a comparison of 23 deaf pupils participating in the project with a baseline group formed by 65 deaf pupils attending the same schools in the previous year. The project pupils were tested before and after the intervention on the NFER-Nelson Age Appropriate Mathematics Achievement Test. The intervention was delivered by the teachers during the time normally scheduled for mathematics lessons. The project pupils did not differ from the baseline group at pretest but performed significantly better at posttest. They also performed at posttest better than expected on the basis of their pretest scores, according to norms provided by the NFER-Nelson Age Appropriate Mathematics Test for assessing the progress of hearing pupils. We conclude that the program was effective in promoting deaf pupils' achievement in numeracy. 相似文献

An important, though somewhat neglected, aspect of learning to spell in English and in many other orthographies is that children have to learn about the conventional spellings for morphemes which often depart from strict letter-sound principles. There is some evidence that backward readers might have great difficulties with these spellings. We looked at a group of backward readers’ (BR) spelling of “ed” in regular past verbs and “wh” in interrogatives, and also at their grammatical awareness and we compared them to one control group matched on chronological age (CA) and to another matched on reading level (RL). The backward readers were considerably behind the CA controls in producing grammatically based spelling patterns correctly and also in the grammatical awareness tasks, but no worse than the RL controls in either of these domains: in fact they were better with the “wh” spellings. We conclude that learning the written language makes a significant contribution to the development of grammatical awareness and this interferes with BR progress in grammatical awareness when they are compared to their cohort. However, there is no evidence of an intrinsic difficulty with grammatical awareness among BR and perhaps this strength could be used to support their spelling. 相似文献

Several conventional spelling sequences for morphemes do not conform to letter-sound correspondence rules. One example is the -ed spelling for the inflectional morpheme at the end of English past verbs. Previous work has shown a close relationship between children's awareness of grammatical distinctions and their success in learning about this spelling sequence. However, this research was with real verbs and the children's spelling might have been influenced by familiarity with the words. To check this, we devised a task with pseudo-verbs. This is a novel use of pseudo-words, which hitherto have been a tool for testing letter-sound knowledge; here the spellings violated letter-sound relationships and followed a morphological pattern. The children heard passages with a pseudo-verb in the past tense and in other tenses and had to write the pseudo-verb in the past tense. The task contained both regular pseudo-verbs, whose stem was the same in the present and past tense, and irregular pseudo-verbs, which had different stems in the present and the past tense. The children's scores in a grammatical awareness task predicted their use of the -ed spelling sequence over a 21 month period. The children also used -ed endings significantly more often in regular than irregular pseudo-verbs. We conclude that the use of -ed endings for regular verbs reflects a morphological spelling strategy based on children's grammatical awareness. 相似文献

Because the spelling of many words in the English language (and in many other languages as well) depends on their morphemic structure, children have to have some knowledge about morphemes in order to learn to read and write. This raises the possibility that children gain much of their explicit knowledge about morphemes as a direct result of learning to read and to spell. We report two large-scale longitudinal studies that support the idea of this kind of causal connection. In the first study children’s success in spelling the inflexion at the end of regular past verbs predicted their performance in two morphological awareness tasks a year later. In the second study the children’s consistency in spelling morphemes predicted their ability to define new words on the basis of their morphemic structure. We conclude that the experience of learning to read and write does affect people’s knowledge of morphemes, and we argue that the causal relationship between morphemic knowledge and reading and writing is probably a two-way one. 相似文献
