How does validating activity contribute to the modeling process?

Contemporary scholars describe mathematical modeling as a transformation of a real-world problem to a mathematical problem and back again. This paper treats a critical issue in the modeling process: how modelers determine if the transformation from the real world to mathematics was carried out well. I present an empirically derived typology of validating activities explaining how validating functions to ensure a mathematical model will yield a reasonably accurate prediction. The typology arose from analysis of four engineering undergraduates’ production of 276 instances of validating. The nuances of validating suggest that creating and maintaining relationships between reality and mathematics is more complex than a transformation and that we should afford a more prominent role to validation in the modeling process.     

Interest in an expository text: How does it flow from reading to writing?

This study investigated the flow of interest in a reading-to-write activity. It was hypothesized that (a) different contents in a text would stimulate different types of interest and (b) different writing tasks would impact differently students’ use of interesting text segments. Participants were 247 11th- and 12th-grade students, who were divided into 6 groups according to a 2 (interesting vs. uninteresting topic) × 3 (type of writing task) design. While reading, students rated novelty, curiosity, impressiveness, importance, and willingness to reflect on each text segment. Participants were then assigned to one of three writing tasks, namely argumentation, text designing, and composition. Results showed that concepts were regarded as important, events/activities as impressive, and evaluations as most worthy of reflection. Topic interest was explicitly expressed mainly in the argumentation condition, where increased topic interest scores after reading and writing were also found.     

How does phonological awareness relate to nonword reading skill amongst poor readers?

This study examined phonological awareness at the level of phonemes and rhyme and related this to nonword naming ability. Poor readers were compared with 11 year old chronological-age controls and 8 year old reading-age controls. The poor reader group was impaired for chronological age in all tasks, and impaired for reading age at nonword naming and phoneme deletion. The poor readers' rhyming skills, however, were commensurate with reading age. Individual variation was observed together with exceptions to the group findings; most poor readers performed within the range of the reading-age controls on the phonological tasks and in nonword naming. Dissociations in phonological skills were evident, including indications that intact awareness of rhyme may not be a prerequisite for the development of phoneme awareness. Furthermore, phoneme awareness correlated significantly with poor readers' word and nonword reading ability, whereas rhyming skill did not. Therefore, phoneme awareness may be more important than rhyming skill in understanding reading disorders.     

Contributions of morphological skill to children’s essay writing

Morphological skills have previously been found to reliably predict reading skill, including word reading, vocabulary, and comprehension. However, less is known about how morphological skills might contribute to writing skill, aside from its well-documented role in the development of spelling. This correlational study examines whether morphological skill, as measured by a sentence generation task tapping both derivational morphology and meta-syntactic skills, predicts performance on a standardized essay writing task for fifth- and eighth-grade U.S. students (N = 233), after controlling for grade level, comprehension, and writing fluency. Multilevel analyses indicated that morphological skill and writing fluency were each uniquely predictive of essay quality, and this finding was consistent regardless of whether accurate spelling was required in the morphological task. Our results suggest that morphological skills play an important role in writing, as has been previously documented in reading and spelling.     

How do different cognitive and linguistic variables contribute to reading in Arabic? A cross-sectional study from first to sixth grade

The contribution of linguistic and cognitive variables to reading processes might vary depending on the particularities of the languages studied. This view is thought to be particularly true for Arabic which is a diglossic language and has particular orthographic and morpho-syntactic systems. This cross-sectional study examined the contribution of phonological, orthographic, morphological, semantic, syntactic, visual perception, rapid automatic naming and phonological working memory abilities to decoding and fluency (the two components of reading). The results, obtained from 1305 native Arabic-speaking children in first–sixth grade, were analyzed using path models. The analysis revealed that memory and orthographic knowledge contributed to both components of reading, while phonological awareness contributed mainly to decoding and rapid automatic naming contributed to fluency. The contribution of morphology to the two components, which appeared already in the first grade, was weak and inconsistent. Finally, the results showed that visual perception, semantics, and syntax predicted neither decoding nor fluency. The data presented here suggest that reading development in Arabic differs from other languages, a finding that might explain certain difficulties in reading acquisition in Arabic. The results are discussed in the light of previous findings in the literature and the specific features of Arabic.     

How can action learning contribute to social capital?

This paper explores the contribution that action learning can make to the formation of social capital via experiences of action learning projects in NHS Pathology Services in the UK. The paper describes the development of action learning practice in recent years, reviews the notion of social capital and considers how action learning might contribute to its formation. A case study of action learning in the development of a locally unified pathology service is used to illustrate the processes by which actions and learnings may be transferred and extended from sets to contribute to organisational learning in wider systems and networks.

How does writing for publication help professional development of teachers? A case study in China

Publications by teachers reporting results or case studies of school-based teacher inquiry activities benchmark their professional development by indicating they have a ‘stance of inquiry’. Such papers also disseminate valuable knowledge to the education community for sharing. Essay or case writing has always been a part of school-based teacher learning in China. The small-scale qualitative study reported here examines the impact of producing publications on the professional development of teachers within the context of educational reform. Findings show that producing publications contributes to teacher development in three ways. First, an expanded knowledge base gives the teachers new understandings of student-based learning. Second, teachers obtain insight into their practices by making their tacit knowledge explicit. Third, teachers have a sense of achievement by theorising personal experience. Publications serve as ‘boundary objects’ which can potentially help teachers achieve and develop their professionalism by disseminating individual knowledge into the public knowledge domain with transformative learning. Such developments, however, normally tend to focus on expanding local pedagogical practice. More emphasis on the notion of ‘teachers as researchers’ through critical reflection may help teachers perform as transformative intellectuals whilst searching for ways to retain teachers’ voices in their written publications.     

How can evaluation contribute to educational policy? the uses of information in Australia

Conclusion There are volumes of data and much other information potentially available for school systems and schools for evaluating performance and modifying policy and practice. There is always a risk of injudicious data gathering that creates more information than can sensibly be used. We often known more than we understand. Careful selection of the data to be used and appropriate analysis and interpretation can turn information into understanding and perhaps, finally, wisdom.

Application of English cohesion theory in the teaching of writing to Chinese graduate students

The English cohesion theory proposed by Halliday and Hasan makes great contributions to the understanding of the coherence and cohesion of the English texts. It should be applicable in the teaching of English writing so as to improve the cohesion in the students＇ compositions. The present paper describes apractice of this order among non-major graduate students, and discusses its results. The conclusion is that teaching activities of this kind can indeed improve the cohesion in the students＇ compositions. Finally the paper raises a few concerning problems which remain to be further explored.     

How different are they? A comparison of Generation 1.5 and international L2 learners’ writing ability

A growing body of literature in second-language writing suggests that the writing ability of international second language (L2) learners, who attend post-secondary education abroad after having completed high school in their home countries, and the so-called Generation 1.5 population, that is, L2 learners who enter post-secondary education after attending high school in the new country, differs. The present study provides much-needed empirical evidence concerning potential differences in the writing ability of these two groups. Many-facet Rasch measurement procedures were used to analyze learners’ writing scores in five components, based on a theoretical model of writing ability: grammatical, cohesive, rhetorical, sociopragmatic, and content control. Results revealed that the international learners performed better overall than the Generation 1.5 learners and that the two groups had opposing strengths and weaknesses in grammatical and sociopragmatic control. Language program administrators and practitioners can use these results when designing curricula addressing the needs of diverse groups of L2 learners.     

How to Move from Power-based to Dialogic Relations? Lessons from Roma Women

In its growth strategy for the coming decade, the EU recognises the Roma as one of several groups especially affected by poverty and social vulnerability. So far, many efforts to reverse this social exclusion have failed; imposed solutions based on power relations have ignored Roma voices and suggestions from the community. As a result, the EU now emphasises the urgency of identifying measures that can effectively help their situation. This article draws on data from a qualitative longitudinal case study of predominantly Roma schools in Spain. It shows how the move from power-based relations with Roma families to more dialogic ones has helped overcome both social and educational exclusion. Two dimensions are identified that facilitate this transition: demonopolisation of the expert knowledge and recognition of the Roma culture. By introducing dialogic relations, these schools have encouraged more Roma women to participate in different domains; they have also increased their academic expectations, moved beyond society's prejudice towards the Roma, and helped new role models to emerge.

How does early childhood care and education affect cognitive development? An international review of the effects of early interventions for children from different social backgrounds

A number of authors have investigated the impact of early childhood education and care programs on the development of children. Often they have focused on the effects on children from socio-economically disadvantaged families. To assess the effects of various preschool programs on cognitive development, recent key studies were reviewed. In addition, the extent to which these programs could establish equal educational opportunities for children from different social backgrounds was evaluated. Program start, intensity, and duration were considered. The findings indicate that the vast majority of recent early education and care programs had considerable positive short-term effects and somewhat smaller long-term effects on cognitive development and that in relative terms children from socio-economically disadvantaged families made as much or slightly more progress than their more advantaged peers. Despite this, early childhood education and care cannot compensate completely for developmental deficits due to unfavorable learning conditions in disadvantaged milieus. Implications for research and policy are discussed.
