Exploring the relationship between physics-related epistemological beliefs and physics understanding     

Christina Stathopoulou  Stella Vosniadou 《Contemporary educational psychology》2007

Three studies are reported that investigated the relationship between secondary school students’ physics-related epistemological beliefs and physics conceptual understanding. Study 1 involved the development of a Greek Epistemological Beliefs Evaluation Instrument for Physics (GEBEP) which was administered to 394 students (10th graders). Study 2 investigated the hypothesis that physics epistemological sophistication as measured by the GEBEP is a good predictor of physics understanding. The participants were selected from the 394 students who participated in Study 1. More specifically we selected the 10% (38) students with the highest scores in the GEBEP (high epistemological sophistication group, HES) and the 10% (38) students with the lowest GEBEP scores (low epistemological sophistication group, LES) and measured their understanding of Newton’s three laws using the Force and Motion Conceptual Evaluation instrument (FMCE) developed by Thornton and Sokoloff (1998). The results showed that the HES group had significantly higher scores in the FMCE than the LES group. Regression analysis showed that beliefs regarding the Construction and Stability of physics knowledge and the Structure of physics knowledge were good predictors of physics understanding. Study 3 re-examined the same hypothesis on a new independent sample of students. The results based on the entire sample, showed again that beliefs regarding the Construction and Stability of physics knowledge predicted physics understanding. Overall, the results suggest that sophisticated physics-related epistemological beliefs are necessary but not sufficient for physics understanding and point to the importance of taking them into consideration in physics education.  相似文献

关于纵向科研经费申请和管理的探讨     

Shen Ya Ping 《大连大学学报》1995,(3)

本文从选题、可行性分析研究、经费预算、组织项目等几个方面论述了应怎样申请纵向科研经费,并就使用原则、使用范围和结算等方面论述了如何管理好纵向科研经费,以便正确合理使用,发挥好经费的应有效用。 高校为顺利开展科研工作并取得预期的成果,必须有足够的科研经费做保证。筹措科研经费的重要渠道是来自国家、省、市有关部门和本校,这就是所谓的纵向科研经费。所以,如何争取纵向科研经费,并管理使用好这类经费,是每一名科研人员和科研管理工作者都关心和需认真研究的问题。本文拟谈谈我对这方面的认识,以与同志们探讨。  相似文献

An assessment of how scientific literacy-related aims are actualised in the National Primary Science curricula in China and Finland     

Yan Wang  Jari Lavonen  Kirsi Tirri 《International Journal of Science Education》2019,41(11):1435-1456

This research compared how the scientific literacy-related goals of the current Chinese and Finnish national science curricula at primary school level are actualised using a revised Programme for International Student Assessment (PISA) scientific literacy framework in the content analysis of the curricula. The content of the curricula focuses principally on knowledge, followed by competencies and attitudes, respectively. The learning context was seen to be thoroughly integrated with the content in both countries. However, the curricula are written in different ways. Generally, the literacy objectives for both curricula are based on scientific knowledge (Vision I) and the application of knowledge-based skills in situations (Vision II). However, they are characterised by implicit views that derive from the pursuit of the value-driven transformation of individuals and society achieved through science education (Vision III). The Chinese curriculum appears to favour the Anglo-American curriculum tradition, whereas the Finnish curriculum appears to be more attached to the Bildung-Didaktik tradition in terms of core tasks and the specification of objectives. The recommendation is that Vision III should be included in the science curricula, and should explicitly relate to social and scientific topics with a view to furthering a scientifically literate public.  相似文献   

The impact of science motivation on cognitive achievement within a 3-lesson unit about renewable energies     

《Studies in Educational Evaluation》2016

Our study analyzed the influence of motivation towards science in relation individual cognitive achievement scores. 232 10th graders of college preparatory school level (‘Gymnasium’) completed a cognitive achievement test three times and a questionnaire quantifying motivation towards science once. A three-lesson module dealt with aspects of the topic renewable energies. The knowledge test was applied one week before (T-0), directly after (T-1) and six weeks after (T-2) participation in the learning module. The questionnaire on science motivation was completed at T-0 in order to receive unaffected data. A test-retest group (acting as control group) of 37 students completed the questionnaires with no intervention. Three motivational groups were selected: highly motivated, intermediate and less motivated. The intervention group showed substantial knowledge gain in short- and in long-term perspectives, almost independently of motivational levels. A positive linear relation between motivation and content knowledge was observable for each test schedule. In particular, intrinsic factors are shown to be responsible for this relationship.We recommend implementing appropriately designed educational settings to promote intrinsic aspects in order to foster performance almost independently of pre-existing knowledge and science motivation We presume pre-existing knowledge as well as learning to be influenced by motivation towards science. Also, pre-existing knowledge may influence individual motivation towards science. Consequently, beyond scientific contents, a focus on motivation of adolescents in science may lead to a synergetic effect for life-long learning.  相似文献   

Models in Physics, Models for Physics Learning, and Why the Distinction may Matter in the Case of Electric Circuits   总被引：1，自引：0，他引：1  

Christina Hart 《Research in Science Education》2008,38(5):529-544

Models are important both in the development of physics itself and in teaching physics. Historically, the consensus models of physics have come to embody particular ontological assumptions and epistemological commitments. Educators have generally assumed that the consensus models of physics, which have stood the test of time, will also work well as teaching models, and for many topics this assumption is at least unproblematic and in many cases productive. However, in the case of electric circuits the consensus models are highly abstract and consequently inaccessible to beginning learners. Certain historically derived analogues for the consensus models are accepted in texts, but these are demonstrably ineffective for helping learners grasp the fundamental concepts of electric circuits. While awareness of other models circulates informally in the teaching community, these are not well documented in the science education literature and rarely referred to in authoritative texts, possibly because the models do not share the ontological assumptions and epistemological commitments that characterise consensus models. Consequently these models have not been subjected to a disciplined critique of their effectiveness for teaching purposes. In this paper I use criteria drawn from the science education literature to reflect on why I have found particular models valuable in teaching electric circuits. These criteria contrast with the epistemological and ontological features that characterise the consensus models of science, and my reflection leads me to attend explicitly to the ways in which meanings are created within physics. This suggests that all models, whether consensus models or not, can be used more knowingly for important educational ends.
