The classification of science into disciplines is at the heart of bibliometric analyses. While most classifications systems are implemented at the journal level, their accuracy has been questioned, and paper-level classifications have been considered by many to be more precise. However, few studies investigated the difference between journal and the paper classification systems. This study addresses this gap by comparing the journal- and paper-level classifications for the same set of papers and journals. This isolates the effects of classification precision (i.e., journal- or paper-level) to reveal the extent of paper misclassification. Results show almost half of papers could be misclassified in journal classification systems. Given their importance in the construction and analysis of bibliometric indicators, more attention should be given to the robustness and accuracy of these disciplinary classifications schemes.  相似文献

This study investigated the strategy characteristics and development of children with mathematical disabilities (MD) in the domain of simple addition and subtraction, in terms of Lemaire and Siegler's model of strategic change, using the choice/no-choice method and the combined chronological-age (CA)/ability-level (AL)-match design. Four groups of children, matched on either CA or mathematical AL, solved a series of 36 problems with the bridge over 10 in four conditions. In the choice condition, children could choose between retrieval, decomposition to 10, and counting on to solve each problem. In the retrieval, decomposition, and counting conditions, they had to answer the same 36 problems using retrieval, decomposition to 10, and counting on, respectively. The results revealed clear differences in the frequency, efficiency, and adaptiveness with which the CA-matched children applied the available strategies. In contrast, we observed no differences in strategy frequency, efficiency, and adaptiveness between the AL-matched children. These results support the hypothesis that the strategy development of children with MD is marked by a delay rather than a specific deficit. Moreover, this study further documents the value of the methodology used to study children's strategy use and development in the domain of simple arithmetic.  相似文献

Based on a synthesis of contributions from differentauthors, we present a theoreticalframework that provides some foundations for schoolscience, and we define someresearch problems. We start from what is already knownabout students' models andcognition in order to construct proposals of didacticalintervention. The cognitive modelof science, developed in the philosophy of science throughstudying scientists' activity,has allowed us to propose an analogous model for schoolscience in which experimentationand language play the key roles. We emphasise the relativeindependence of school scienceand scientists' science.  相似文献

Information is presented about the organization of graduate studies, based on questionnaire responses of 582 coordinators of Canadian graduate programs. These coordinators, who were representative of disciplines and geographic regions, provided information about a wide range of matters, including enrolments, staff, admissions, supervision, research, publications, financial support, teaching experience, and completion rates and times. Many substantial differences were noted among the percentage frequencies of responses for departments classified by discipline and size. For example, students were perceived to choose their doctoral theses topics themselves much more frequently in education, social sciences, and humanities than in engineering, medical sciences, physical sciences, and biological sciences. Also, departments with smaller numbers of full-time graduate students tended to provide all doctoral students, with some teaching experience to a greater extent than did larger departments.  相似文献

We study the comprehension of a multimedia technical document about gear functioning by young pupils. The research is focused on the effect of three factors on the construction of a mental model: illustration format (animated versus static) signaling cues (presence versus absence) learner-control of information delivery (three rhythms of presentation: speed, slow and self-controlled). The experimental procedure, conducted with 123 children, follows three phases: pre-test, individual passation of the lesson, comprehension test, delayed post-test. The goal of the pre-test is the evaluation of prior knowledge about gears, but also the control of spatial and verbal working memory aptitude and reading performance. The results show an effect of the animated format, of signaling cues and of the rhythm on the immediate comprehension test and delayed test. For the immediate comprehension test, these effects are different according to the kind of comprehension question (recall, transfer, explanation). These effects are maintained at the delayed post-test, for the self-controlled condition and for the pupils with low prior knowledge. The factor information delivery rhythm shows an effect for the delayed post-test. Our observation device of the behaviour of the child during the lesson was specially designed to explore the reading strategies between the medias.  相似文献

This study addresses the issue of illusion of incompetence among elementary school children. The first objective is to examine whether teachers are able to recognize children with an illusion of incompetence, The second objective is to see whether teachers’ appraisal of the behaviours and psychological characteristics of these children differ from their appraisals of other children. Seventy-four teachers and their 684 pupils from the fourth and fifth grades who were participating in a larger project were examined. By and large, only 31.3% of the pupils affected by an illusion of incompetence were identified as such by their teachers. However, teachers evaluated boys with an illusion of incompetence as being less autonomous, having a more negative mood and being more withdrawn than their peers. The teachers did not report these characteristics in girls with an illusion of incompetence. The discussion focuses on various hypotheses likely involved in teachers’ difficulty in identifying children whose self-appraisals of competence are negative.  相似文献

ABSTRACT

This article focuses on the interplay between institutional arrangements, family strategies, and market devices in the transition to higher education (HE) in France with a view to documenting both persistent features of the French ‘conservative’ educational regime and recent changes, in particular those related to neo-liberal influences. Using a theoretical model inspired by research on welfare regimes and integrating key elements of the sociology of networks, institutions, and markets, as well as data from a comprehensive qualitative study, the article focuses on three main topics: the impact of both institutional stratification and family choices on segregation and channelling into HE; the framing of students’ choices generated by impersonal policy instruments and personal human guidance; the role of private providers and agencies, as well as the devices they use to influence students’ transition to HE. The conclusion emphasises the impact of these different processes on the perpetuation of educational inequalities.  相似文献

336 students, 186 girls and 150 boys were met at the end of the school year, both at grade six and at Secondary one, in order to examine the impact of the transition from elementary to secondary school on various motivational variables. Analyses showed changes in self-efficacy beliefs and learning goals, whatever students’ level of achievement and gender. However, self-efficacy beliefs appeared as the most powerful predictor of academic performance at both school levels. In addition, the pattern of relations between academic performance and the variables examined was relatively similar at both times of measurement. The discussion focuses on changes in self-efficacy beliefs and learning goals and on their relations to academic performance.  相似文献

This article uses a fictionalized scenario to examine how three students at an “ordinary” suburban high school in Canada negotiate the context-specific conditions, discourses, and practices that make schools important sites of identity formation. It argues that drawing from Foucault's ideas on the “subjection” of individuals, as well as from the field of performance studies, provides a fresh perspective to redress the potential mismatches between official multicultural education discourses and the lived schooling realities of students. In the process, it demonstrates how subjection and adolescent performativity can be useful analytics through which to understand student identities and/in schooling. The article concludes with some implications for shifts in policy, pedagogy, and practice to help schools engage with student diversity.  相似文献

Situations are often regarded as the panacea which guarantees concretisation of abstract notions. Recent research results have led us to qualify this opinion. After analysing briefly the notion of situation, we raise various issues on the basis of the responses of children aged 11–15 to the racing car problem. We observed various limits brought about by the situation in the abstraction prócess, and also that the task involved more abstract notions (even pictorial) than expected. The conclusion singles out some principles ensuring a better use of situations and points out key problems such as the role of mental images and the importance of the spoken language.  相似文献
