Secondary School Students’ Construction and Use of Mathematical Models in Solving Word Problems     

Salvador Llinares  Ana Isabel Roig 《International Journal of Science and Mathematics Education》2008,6(3):505-532

This study focussed on how secondary school students construct and use mathematical models as conceptual tools when solving word problems. The participants were 511 secondary-school students who were in the final year of compulsory education (15–16 years old). Four levels of the development of constructing and using mathematical models were identified using a constant-comparative methodology to analyse the student’s problem-solving processes. Identifying the general in the particular and using the particular to endow the general with meaning were the key elements employed by students in the processes of construction and use of models in the different situations. In addition, attention was paid to the difficulties that students had in using their mathematical knowledge to solve these situations. Finally, implications are provided for drawing upon student’s use of mathematical models as conceptual tools to support the development of mathematical competence from socio-cultural perspectives of learning.  相似文献   

也谈“通感”——从·心理学到认知语言学     

宋兆娟 《安顺师范高等专科学校学报》2008,10(1):33-36

通感是一种语言现象,也是一种认知现象,有着生理学和心理学基础。从认知的角度来看,通感现象是不同感官之间的经验映射,是一种认知方式,它的认知机制与隐喻相同。  相似文献   

大学精神是高校形象建设的理念基础   总被引：3，自引：0，他引：3  

彭向刚 《大学教育科学》2008,(5):12-17

高校形象是高校综合实力的表征,是社会公众对高校的价值追求、功能作用、地位层次、基本特征等方面的一种共性反映和普遍评价。一所大学的形象具有怎样的风格,与众多因素有关,其中有没有独树一帜抑或富有特色的教育理念和大学精神是至关重要的。大学精神是大学这种特殊组织所秉持的宗旨,是大学在长期发展中所形成的引领大学方向、约束大学行为的价值观系统以及在此基础上形成的规范体系。大学精神决定了高校形象建设的战略规划,决定了高校形象建设的主体人格,决定了高校形象的价值实现,决定了高校品牌的格调。可以说,大学精神是一所大学的灵魂,是高校形象建设的理念基础。  相似文献   

观念世界的教育变革 ――现代小说中的教育叙事研究刍议   总被引：1，自引：0，他引：1  

田正平  陈桃兰 《华东师范大学学报(教育科学版)》2008,26(3):71-76

现代小说里的教育叙事,生动地记录了教育现代化进程中的某些片段,形象地反映了某个特定历史时期教育变革的时代主题。这些变革虽然只是通过现代小说体现的,但这种观念形态的呈现对于研究现代教育史有着特殊的价值。它不仅可以拓宽教育史研究的视域、丰富教育史研究的资料,还可以完善教育史著作的文本写作。对这一领域的研究,前人已经取得了一些开拓性的成果,但仍需要进一步引起重视。  相似文献   

仿拟修辞的认知解读   总被引：1，自引：0，他引：1  

吕煦 《河北师范大学学报(哲学社会科学版)》2008,31(6):105-109

仿拟不仅是一种修辞手段．更是一种认知活动;对仿拟的认知解读包含着概念整合过程。从认知的角度,运用合成空间理论并结合语境、关联两个相关要素来描述仿拟概念整合过程中的一系列状态．从而把仿拟生成和推理的动态机制有效地揭示出来。对仿拟的认知分析与探索,一方面深化了修辞学研究。另一方面证明了合成空间理论对仿拟言语行为有着很强的阐释力。有助于人们对该理论的进一步理解和运用。  相似文献

Active Learning session based on Didactical Engineering framework for conceptual change in students’ equilibrium and stability understanding     

Michael Canu  Mauricio Duque  Cécile de Hosson 《European Journal of Engineering Education》2017,42(1):32-44

ABSTRACT

Engineering students on control courses lack a deep understanding of equilibrium and stability that are crucial concepts in this discipline. Several studies have shown that students find it difficult to understand simple familiar or academic static equilibrium cases as well as dynamic ones from mechanics even if they know the discipline’s criteria and formulae. Our aim is to study the impact of a specific and innovative classroom session, containing well-chosen situations that address students’ misconceptions. We propose an example of Active Learning experiment based both on the Didactical Engineering methodology and the Conceptual Fields Theory that aims at promoting a conceptual change in students. The chosen methodology allows, at the same time, a proper design of the student learning activities, an accurate monitoring of the students’ rational use during the tasks and provides an internal tool for the evaluation of the session’s efficiency. Although the expected starting conceptual change was detected, it would require another activity in order to be reinforced.  相似文献   

Effects of Conceptual Change and Traditional Confirmatory Simulations on Pre-Service Teachers’ Understanding of Direct Current Circuits     

Mustafa Baser 《Journal of Science Education and Technology》2006,15(5-6):367-381

The objective of this research is to investigate the effects of simulations based on conceptual change conditions (CCS) and traditional confirmatory simulations (TCS) on pre-service elementary school teachers’ understanding of direct current electric circuits. The data was collected from a sample consisting of 89 students; 48 students in the experimental group who were taught simulations based on CCS, and 41 students in control group who followed the TCS. Subjects in both groups used open source software (Qucs) to simulate electric circuits. All students were administered Electric Circuits Concepts Test (DIRECT), Science Process Skills Test, Physics Attitude Scale, and Computer Attitude Scale before the treatment. Pre-test analyses revealed that there is no significant difference between experimental and control groups in terms of understanding of direct current electricity. After completing 3 weeks treatment, all students received the DIRECT again as a post-test. Analysis of covariance was used. Science process skills and attitudes toward computers were taken as covariates. The results showed that the conceptual change based simulations caused significantly better acquisition of conceptual change of direct current electricity concepts than the confirmatory simulation. While science process skills and attitudes towards computer made significant contributions to the variations in achievement, gender differences and interactions between gender and treatment did not. Eleven weeks later, the DIRECT was reapplied to the students in both groups. Eleven weeks delayed post-test results showed that the experimental group outperformed the control group in understanding of direct current electric concepts.  相似文献   

概念隐喻理论与英语词汇教学     

郭霞  赵海萍 《山西财经大学学报(高等教育版)》2008,11(4):53-55

莱考夫和约翰逊的概念隐喻理论认为,隐喻是人类的认知现象,是一种思雏方式。文章将概念隐喻理论具体运用到大学英语的词汇教学中,探讨了如何通过概念隐喻来学习英语多义词、英语习语以及如何通过概念隐喻将相关词汇联系起来习得。  相似文献
