Models and Paradigms in Kuhn and Halloun     

Paul Joseph Wendel 《Science & Education》2008,17(1):131-141

In Modeling Theory in Science Education, Halloun (2004) adopts the word ‘paradigm’, but his use of the term is radically different from that of Kuhn. In this paper, I explore some of the differences between Kuhn’s paradigms and Halloun’s paradigms. Where Kuhn’s paradigms are public, community-defining exemplars of practice, Halloun’s paradigms are private, individualized ways of thinking. Where Kuhn writes of the paradigm shift as a revolutionary, vision-altering conversion experience, Halloun writes of a gradual evolution from one way of thinking to another and an easy back-and-forth switch between paradigms. Since Kuhn’s paradigms are self-enclosed and incommensurable, there is no objective standard by which one paradigm can be shown to be superior to the other. But Halloun uses ‘viability’ as a standard for paradigm choice. Underlying all of this is the more basic question of whether the history of science is an appropriate metaphor for student progress in the classroom. I conclude with some brief thoughts on this question.  相似文献   

试析美国研究型大学基层学术组织模式   总被引：3，自引：0，他引：3  

ZHENG Xiao-qi  WANG Zhan-rui 《高等教育研究》2007,(12)

美国研究型大学基层学术组织是以学科为基础的独立的、自主的学术组织。其组织规模主要根据教学科研任务的需要来决定。其内部管理以教授统治为主,采取的是少数服从多数的决策机制。总结和归纳美国研究型大学基层学术组织的现状与改革动向,对于探讨我国研究型大学未来的改革重点与方向具有重要的借鉴意义。  相似文献

On-line estimation of concentration parameters in fermentation processes     

Xiong ZH  Huang GH  Shao HH 《Journal of Zhejiang University. Science. B》2005,6(6):530-534

INTRODUCTION Saccharomycete, closely linked with human life, is the only microbe that has been utilized to the extent of over a million tons in the world, and is one of the modelled biological bacteria mostly used in modern genetic engineering. Since there are no effective online instruments for measuring the production or resultant concentration, which is a very important quality index in fermentation process, soft sensors (Martin, 1997; Tham et al., 1991; Assis and Filho, 2000; Salgad…  相似文献

Reconsidering the Character and Role of Inquiry in School Science: Analysis of a Conference   总被引：2，自引：1，他引：1  

Richard Grandy  Richard A. Duschl 《Science & Education》2007,16(2):141-166

We summarize a conference on scientific inquiry bringing together science educators, cognitive scientists and philosophers of science with three goals:

1.	to establish how much consensus exists about scientific inquiry,
2.	to discuss implications of that consensus for teaching science,
3.	to identify areas where consensus is lacking to establish where further research and discussion would be most valuable.

五年一贯制教师教育模式作为自20世纪80年代兴起的一种整合型教师教育模式,经过二十余年的发展与完善,在美国当今的教师教育研究与实践中已占有一席之地。弗吉尼亚大学作为该模式的首创者和成功践行者,其五年一贯制模式得到了多方的高度认可。该模式中一体化的培养体制、高度融合的课程以及密切合作的师资是践行教师教育理论与实践、学科专业教育与教育专业教育有机融合理念的集中体现和重要保障。  相似文献   

Performance factors and immigration. Impact of individual and school variables / Factores de rendimiento e inmigración. Impacto de variables individuales y escolares     

Paula Elosua 《Cultura y Educación》2019,31(1):1-30

The way schools address migratory movements has a direct impact on integration and social cohesion, making the in-depth study of factors that affect the lower performance of immigrant students in comparison with non-immigrants essential. Using a methodology based on random coefficient models, this paper analyses the differential effect of individual level and school level variables on the estimation of mathematical competence in non-immigrant and immigrant populations. Data are extracted from an educational assessment programme carried out in the Basque Autonomous Community. The sample consists of 16,981 students with an average age of 13.7 years, of which 1,369 are immigrant students. The results reveal that individual and family-level variables show significantly higher impact on student performance than school-level variables. The article concludes by emphasizing the importance of investing in policies to support diversity that work at family level, as a means to achieve fuller equity.  相似文献
