The effect of the number of syllables on handwriting production     

Eric Lambert  Sonia Kandel  Michel Fayol  Eric Espéret 《Reading and writing》2008,21(9):859-883

Four experiments examined whether motor programming in handwriting production can be modulated by the syllable structure of the word to be written. This study manipulated the number of syllables. The items, words and pseudo-words, had 2, 3 or 4 syllables. French adults copied them three times. We measured the latencies between the visual presentation and the first production (L1), the first and second production (L2), and the second and third production (L3). The results show an effect of the number of syllables in L1 for pseudo-words but not for words and on L2 and L3 for all the items (Experiments 1 and 2). Experiment 3 ruled out an interpretation of the latencies for pseudo-words in terms of reading time with a delayed copying task. Experiment 4 replicated the previous results and assessed the effect of varying the temporal interval between the second and third trials. The results of the four experiments confirm the role of the syllable in word writing. The number of syllables of a word modulates the time course of handwriting production.

Ponctuation et Connecteurs: Une Approche Textuelle et Génétique     

Michel Fayol  Bernard Lété 《European Journal of Psychology of Education - EJPE》1987,2(1):57-71

Two experiments were carried out in order to study the development of textual punctuation use in children from 7 to 13. Four unpunctuated stories (following Mandler & Johnson’s narrative grammars 1977) involving or not a connective (et/alors/après) at different places were submitted to subjects who had to write them down in adding punctuation marks. The results show a strong textual impact on the frequency of punctuation which is higher at the beginning and at the end of the stories. We found also a strong impact of connectedness: the frequencies and types of punctuation marks varied in relation to connectives:et was rarely punctuated;alors was mainly associated with commas whereasaprès was more often associated whith periods. These effects were significant mainly from 11 years of age on, except for the impact ofet already observed at 7 years of age.  相似文献   

Exemplarism in moral education: Problems with applicability and indoctrination     

Michel Croce 《Journal of moral education》2019,48(3):291-302

ABSTRACT

This article introduces an account of moral education grounded in Zagzebski’s recent Exemplarist Moral Theory and discusses two problems that have to be solved for the account to become a realistic alternative to other educational models on the market, namely the limited-applicability problem and the problem of indoctrination. The first problem raises worries about the viability of the account in ordinary circumstances. The second charges the proposed educational model with indoctrinating students. The main goal of this article is to show how an exemplar-based account of moral education can handle both problems without compromising its structure and upshot.  相似文献   

Nature of Science and Science Content Learning     

Hanno Michel  Irene Neumann 《Science & Education》2016,25(9-10):951-975

Besides viewing knowledge about the nature of science (NOS) as important for its own value with respect to scientific literacy, an adequate understanding of NOS is expected to improve science content learning by fostering the ability to interrelate scientific concepts and, thus, coherently acquire scientific content knowledge. However, there is a lack of systematic investigations, which clarify the relations between NOS and science content learning. In this paper, we present the results of a study, conducted to investigate how NOS understanding relates to students’ acquisition of a proper understanding of the concept of energy. A total of 82 sixth and seventh grade students received an instructional unit on energy, with 41 of them receiving generic NOS instruction beforehand. This NOS instruction, however, did not result in students having higher scores on the NOS instrument. Thus, correlational analyses were performed to investigate how students’ NOS understanding prior to the energy unit related to their learning about science content. Results show that a more adequate understanding of NOS might relate to students’ perspective on the concept of energy and might support them in understanding the nature of energy as a theoretical concept. Students with higher NOS understanding, for example, seemed to be more capable of learning how to relate the different energy forms to each other and to justify why they can be subsumed under the term of energy. Further, we found that NOS understanding may also be related to students’ approach toward energy degradation—a concept that can be difficult for students to master—while it does not seem to have a substantive impact on students’ learning gain regarding energy forms, transformation, or conservation.  相似文献   

Ignis Fatuus Effect of Faculty Category: Is the Tenure Versus Non-Tenure Debate Meaningful to Students’ Course Experiences?     

Jessica Ostrow Michel  Diana Chadi  Marisol Jimenez  Corbin M. Campbell 《Innovative Higher Education》2018,43(3):201-216

The American professoriate is shifting its majority makeup from tenure track to non-tenure track faculty members. Less known, though, is what the implications of this shift are for students’ course experiences. We sought to examine the extent to which the teaching practices, with regard to academic rigor and cognitively responsive teaching, differ between faculty category using observational measures of teaching in the classroom. We found that broad categorizations of faculty may not be meaningful unless they are examined in particular contexts, such as discipline and class size.  相似文献   

Screening the active constituents of Chinese medicinal herbs as potent inhibitors of Cdc25 tyrosine phosphatase, an activator of the mitosis-inducing p34cdc2 kinase     

Yang H  Zheng S  Meijer L  Li SM  Leclerc S  Yu LL  Cheng JQ  Zhang SZ 《Journal of Zhejiang University. Science. B》2005,6(7):656-663

Objective: To screen and evaluate the active constituents of Chinese medicinal herbs as potent inhibitors of Cdc25 phosphatase. Methods: The affinity chromatography purified glutashione-S-transferase/Cdc25A phosphatase fusion protein and Cdc2/cyclin B from the extracts of starfish M phase oocytes are used as the cell cycle-specific targets for screening the antimitotic constituents. We tested 9 extracts isolated from the Chinese medicinal herbs and vegetables including the agents currently used in cancer treatment by measuring the inhibition of Cdc25A phosphatase and Cdc2 kinase activity. The antitumor activity of the extracts was also evaluated by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay and flow cytometry. Results: Cdc25A inhibitory activity and antitumor activity are detected in the extracts isolated from three Chinese medicinal herbs Agrimona pilosa; Herba solani lyrati; Galla chinesis. Conclusion: We found three extracts isolated from Chinese medicinal herbs have potential inhibitory activity of Cdc25 phosphatase using a highly specific mechanism-based screen assay for antimitotic drug discovery.  相似文献   

Genetic evidence for bidirectional effects of early lexical and grammatical development     

Dionne G  Dale PS  Boivin M  Plomin R 《Child development》2003,74(2):394-412

This article addresses the autonomy hypothesis of vocabulary and grammar and bootstrapping mechanisms in early language development. Two birth cohorts of 1,505 and 1,049 same-sex twin pairs from the UK were assessed at 2 and 3 years on grammar and vocabulary, using adapted versions of the MacArthur Communicative Development Inventory. Vocabulary and grammar correlate strongly at both 2 and 3 years in both cohorts. Multivariate genetic modeling reveals a consistently high genetic correlation between vocabulary and grammar at 2 and 3 years. This finding suggests the same genetic influences operate for both vocabulary and grammar, a finding incompatible with traditional autonomy hypothesis, at least in early acquisition. Crosslagged longitudinal genetic models indicate both lexical and syntactical bootstrapping operate from 2 to 3 years.  相似文献   

Complex Education Systems: from steering change to governance     

Alain Michel 《European Journal of Education》2016,51(4):513-521

The theories and approaches of steering/monitoring a process of change within education systems have evolved over the last 20 years or so as a result of many factors such as globalisation and decentralisation, a faster pace of change, increasing expectations and demands from various stakeholders (parents, employers, teacher unions, etc.) and the growing influence of OECD and of the EU in the field of education because of some more or less explicit standards and policy recommendations. All these evolutions contributed to increase the complexity of the education systems and of the instruments and procedures required to establish some coherence between the initiatives of a large number of more autonomous stakeholders. Our main objective here is to describe how the previous notions and concepts used in analysing the conditions for steering education systems have been gradually integrated within a larger paradigm: the ‘governance of multi‐level complex education systems’.  相似文献   

p2pDating: Real life inspired semantic overlay networks for Web search     

Josiane Xavier Parreira  Sebastian Michel  Gerhard Weikum 《Information processing & management》2007

We consider a network of autonomous peers forming a logically global but physically distributed search engine, where every peer has its own local collection generated by independently crawling the Web. A challenging task in such systems is to efficiently route user queries to peers that can deliver high quality results and be able to rank these returned results, thus satisfying the users’ information need. However, the problem inherent with this scenario is selecting a few promising peers out of an a priori unlimited number of peers. In recent research a rather strict notion of semantic overlay networks has been established. In most approaches, peers are connected to other peers based on a rigid semantic profile by clustering them based on their contents. In contrast, our strategy follows the spirit of peer autonomy and creates semantic overlay networks based on the notion of “peer-to-peer dating”. Peers are free to decide which connections they create and which they want to avoid based on various usefulness estimators. The proposed techniques can be easily integrated into existing systems as they require only small additional bandwidth consumption as most messages can be piggybacked onto established communication. We show how we can greatly benefit from these additional semantic relations during query routing in search engines, such as Minerva, and in the JXP algorithm, which computes the PageRank authority measure in a completely decentralized manner.  相似文献
