‘Interdisciplinary strategies’ in U.S. research universities   总被引：5，自引：0，他引：5  

Creso M. Sá 《Higher Education》2008,55(5):537-552

In the context of increasing support for interdisciplinary modes of research, many in the policy, scientific, and academic communities propose that universities should change structurally to reduce the barriers to investigation that involves researchers from multiple disciplines. This paper examines ‘interdisciplinary strategies’ in U.S. research universities—deliberate efforts to spur collaborative research across traditional departmental and disciplinary boundaries, including the creation and adaptation of university policies, practices, and structures. It identifies and analyzes the use of incentive grants to initiate new interdisciplinary units, the establishment of ‘campus-wide institutes’ that steer campus investments in interdisciplinary areas, and new modes of faculty hiring and evaluation. Illustrative examples are provided, and the implications of these strategies are discussed.

Understanding argumentation about socio-scientific issues on energy: a quantitative study with primary pre-service teachers in Spain     

Carolina Martín-Gámez  Sibel Erduran 《Research in Science & Technological Education》2018,36(4):463-483

Background Argumentation is an important discourse process in science that needs to be taught and learned as part of a repertoire of strategies to support the acquisition of scientific literacy. Research in science education indicates that beliefs or perceptions and the epistemological orientations of teachers influence their approaches to science teaching.

Purpose The paper aims to illustrate primary pre-service teachers’ understanding of argumentation based on a study using quantitative methodology. In particular, it aims to illustrate how these teachers view quality of arguments and teaching strategies related to argumentation in the context of a socio-scientific issue on energy.

Sample 332 pre-service teachers enrolled in a university teacher education programme in Spain were investigated. Many studies on argumentation have been conducted with small sample sizes of teachers. Hence, given the sample size, the study provides findings that are likely to be generalisable.

Design and methods A questionnaire was administered to the participants. The design of the questionnaire was guided by some existing analytical tools which were adapted for primary education purposes in the context of socio-scientific issues. This adaptation is novel in that the questionnaire items can potentially be used as diagnostic questions to assess primary teachers’ understanding of argumentation.

Results The results suggest that pre-service teachers had difficulty in understanding arguments and different pedagogical strategies to promote argumentation in classroom. For example, they did not understand the role and the meaning of warrants in scientific arguments and their understanding of the use of different kind of strategies is limited to debates, open discussions and experiments. The age range of the participants and the length of teaching experience had no impact on the quality of their understanding of argumentation.

Conclusions Pre-service science teacher education will benefit from incorporation of more robust and lengthy sessions on argumentation. For example, sessions could focus on quality as well as structure of arguments in science and more diverse pedagogical strategies to support argumentation in science lessons, such as the use of writing frames and presentations.  相似文献   

The Interplay between Habitus,Social Variables and Occupational Preferences     

vilhjálmsdóttir  Gudbjörg  arnkelsson  Gudmundur 《International Journal for Educational and Vocational Guidance》2003,3(2):137-150

European researchers have recently introduced Bourdieu’s habitus theory and research methods into the research field of career development. The advantage of Bourdieu’s theory is to overcome the theoretical problems that in this field have resulted from overemphasis on individual aspects of career development at the expense of social aspects. The habitus concept allows for the dichotomy between the individual and the social dimensions to be overcome. The research reported here looks at the interplay between habitus, social variables and career preferences but in a younger age group than has previously been studied. It also wonders whether habitus groups exist in the relatively homogenous population of Iceland at a relatively young age, i.e., before divergence in the educational system. Analyses resulted in five habitus groups being formed on the basis of endorsement of cultural and leisure activities. Furthermore, the five groups differed both in terms of sex composition and — importantly — of preferred future occupations. It was concluded that habitus groups form readily and have important implications for research and practice within the field of career counselling. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献   

Children's perseverative appearance-reality errors are related to emerging language skills   总被引：1，自引：0，他引：1  

Deák GO  Ray SD  Brenneman K 《Child development》2003,74(3):944-964

Two experiments explored the communicative bases of preschoolers' object appearance-reality (AR) errors. In Experiment 1, 3-, 4-, and 5-year-olds (N = 36) completed the AR test (with high- and low-deceptive objects), a control test with the same discourse structure but nondeceptive stimuli, and stimulus naming and memory tests. AR performance correlated positively with control (discourse) and naming test performance. Object deceptiveness had little effect. In Experiment 2, 3- and 4-year-olds (N = 64) completed AR tests that experimentally varied question phrasing and use of exemplar objects. Children also completed memory, vocabulary, and control tests (of verbal perseveration). AR performance variance was predicted by a composite perseveration score from three non-AR tasks, vocabulary, and exemplars. The results indicate that the discourse structure of the AR test elicits a perseverative tendency that is mediated by children's verbal knowledge.  相似文献   

Measuring systematic long-term trajectories of school effectiveness improvement     

Juan Pablo Valenzuela  Cristián Bellei  Claudio Allende 《School Effectiveness & School Improvement》2016,27(4):473-491

The objective of this study was to identify trajectories of school improvement experienced by Chilean elementary schools over the last decade. Using econometric analysis and controlling for potential confounding factors, we created an index of school performance combining outcome indicators focused on different school dimensions, and estimated the 2002/2010 evolution of school improvement for all Chilean schools with available data. Broadly, we estimated an average increase in the school performance of about 0.19 SD; nevertheless, while 41% of the schools increased their educational performance by at least 0.1 SD, 25% of the schools decreased it during the same period; we also found that improving school effectiveness was more probable among schools with lower student socioeconomic status (SES). Finally, we found that the observed school improvement trajectories tended to be non-linear; thus, we estimated that only 13.4% of the schools improved their performance in a systematic way during the entire decade.  相似文献   

Attitudes towards sexuality information for adolescents: what parents should and should not say     

Claudia Pineda Marin  Maria Teresa Munoz Sastre  Diego Alfonso Murcia  Mateo Bernal Castañeda  Angie Briceño Hernández 《Sex education》2019,19(5):582-596

The goal of this study was to investigate the attitudes of Colombians with respect to what can and what must not be said to young people of different ages and genders regarding sexuality. A convenience sample of 329 adults, aged 18–64 years, living in Bogotá participated in the study. They were presented with a set of 36 vignettes describing situations in which either a young girl or a young boy seemed to be concerned about sexuality and sexual relationships. Each scenario contained three items of information: the child’s gender, age and the parent’s decision (e.g. not to say anything regarding sexuality). Through cluster analysis, seven qualitatively different sets of attitudes were found. The five most common ones were: (i) it is never appropriate to talk about sexual matters (6%); (ii) delegate this responsibility to the school nurse (4%); (iii) provide incomplete information restricted to the biology of sexuality (11%); (iv) provide comprehensive information but with a recommendation of abstinence (28%); and (v) provide comprehensive information and a recommendation of pre-marital sexual experience (36%). Although it was expected that attitudes would vary as a function of the young person’s gender and age, such variations proved to be limited in their extent.  相似文献   

The impact of visuals: using a poster to present metaphor     

Ana Ma Roldán Riejos  Paloma Úbeda Mansilla  Ana Ma Martín Castillejos 《European Journal of Engineering Education》2001,26(3):301-310

Studying metaphor with students from similar fields but from different specializations may seem an overwhelming experience. However, the use of a contextualized poster where the images are more important than the actual words has demonstrated how the use of images in the classroom is a valuable tool. Analysis of a questionnaire handed out to a sample of 'English for Specific Purposes' students confirmed these conclusions. The following paper deals with the pedagogical implications that the use of a poster has proved to have with a multidisciplinary group of students.  相似文献   

Comparing the phonological and double deficit hypotheses for developmental dyslexia     

Pennington  Bruce F.  Cardoso-Martins  Cláudia  Green  Phyllis A.  Lefly  Dianne L. 《Reading and writing》2001,14(7-8):707-755

This study tested the predictions of thephonological and double deficit hypotheses byexperimentally examining speech perception,phoneme awareness, lexical retrieval (serialand discrete), articulatory speed, and verbalSTM in school age child (N = 35) and adolescent(N = 36) dyslexics, and both chronological age(CA) and reading age (RA) controls. Theresults confirmed the findings of previousstudies of a deficit in phoneme awareness indevelopmental dyslexia. At both age levels,dyslexics performed significantly more poorlythan both their CA and RA controls. Althoughdeficits in the other processes investigated,particularly in rapid serial naming, were alsoapparent, they were not as clear-cut as thedeficit in phoneme awareness. In general,definite evidence of a deficit in rapid serialnaming was limited to the more severelyimpaired dyslexics. Furthermore, although rapidserial naming contributed independent variationto various literacy skills, its contributionwas modest relative to the contribution ofphoneme awareness, regardless of whether theliteracy skill relied more or less heavily onphonological or orthographic coding skills. Further analyses suggested that variation inrapid serial skill is particularly importantfor fluent reading of text, whereas phonemeawareness is particularly important for thedevelopment of the ability to read byphonologically recoding letters or groups ofletters in words into their phonological codes.This explains the relatively strongcontribution of phoneme awareness to readingand spelling ability in general. In sum, thephonological hypothesis offers a moreparsimonious account of the present resultsthan the double deficit hypothesis.  相似文献

Detection of Differential Item Functioning with Nonlinear Regression: A Non‐IRT Approach Accounting for Guessing          下载免费PDF全文

Adéla Drabinová  Patrícia Martinková 《Journal of Educational Measurement》2017,54(4):498-517

In this article we present a general approach not relying on item response theory models (non‐IRT) to detect differential item functioning (DIF) in dichotomous items with presence of guessing. The proposed nonlinear regression (NLR) procedure for DIF detection is an extension of method based on logistic regression. As a non‐IRT approach, NLR can be seen as a proxy of detection based on the three‐parameter IRT model which is a standard tool in the study field. Hence, NLR fills a logical gap in DIF detection methodology and as such is important for educational purposes. Moreover, the advantages of the NLR procedure as well as comparison to other commonly used methods are demonstrated in a simulation study. A real data analysis is offered to demonstrate practical use of the method.  相似文献
