根据Klinge和Nicolle的论述,句子的成分可分为命题内容和操作成分两类。命题内容传递概念信息.而操作成分则传递程序信息。句子表达的语言意义就是程序信息与概念信息的结合。概念信息和程序信息这两个概念有助于人们更好地理解英语时态的意义。  相似文献

数学不仅是较简洁、较深刻表达物理概念、规律的语言,而且是研究物理学的抽象思维和推理的工具.在物理发展过程中,观察和实验是物理学的基础,而数学是物理学研究不可缺少的工具,借助它收集信息、分析信息、处理信息,进而建立物理概念和推演物理规律,建立物理学的理论体系.例如天体力学结合数学推导,  相似文献

Good conceptual understanding of physics is based on understanding what the key concepts are and how they are related. This kind of understanding is especially important for physics teachers in planning how and in what order to introduce concepts in teaching; connections which tie concepts to each other give direction of progress—there is “flux of information” so that what was learned before provides the basis for learning new ideas. In this study, we discuss how such ordering of concepts can be made visible by using concept maps and how they can be used in analysing the students’ views and ideas about the inherent logic of the teaching plans. The approach discussed here is informed by the recent cognitively oriented ideas of knowledge organisation concentrating on simple knowledge organisation patterns and how they form the basis of more complex concept networks. The analysis of such concept networks is then very naturally based on the use of network theory on analysing the concept maps. The results show that even in well-connected maps, there can be abrupt changes in the information flux in the way knowledge is passed from the initial levels to the final levels. This suggests that handling the information content is very demanding and perhaps a very difficult skill for a pre-service teacher to master.  相似文献

In view of the lack of work on the understanding of resistance concept, we studied the understanding that high school students (from the eighth to the twelfth grades) were able to develop with regard to the interrelationships between this concept, and the potential difference and current concepts (Ohm's law). In addition, we explored the immediate effects of exposure to electricity courses on the intuitive mastery of these relationships. The participants were presented with information on potential difference and intensity of current and asked to predict the corresponding resistance values. In this current-potential difference context, the resistance concept was difficult to understand. For the majority of participants, resistance was a direct function of both current and potential difference, which is more reminiscent of the concept of power than of the concept of resistance. The systematic teaching of electricity concepts and Ohm's law had only limited, positive as well as negative, effects on the understanding of these relationships. The implications for education are discussed.  相似文献

The theoretical background and different methods ofconcept mapping for use in teaching and in research on learning processes are discussed. Two mathematical projects, one on fractions and one on geometry, are presented in more detail. In the first one special characteristics of concept maps were elaborated. In the second one concept mapping allowed students' individual understanding to be monitored over time and provided information about students' conceptual understanding that would not have been obtained using other methods. Regarding the students' individual concept maps in more detail there were some additional findings: (i) The characteristics of the maps change remarkably from fourth grade to sixth grade; (ii) There is some evidence that prior knowledge related to some mathematical topics plays a very important role in students' learning behaviour and in their achievement; (iii) Concept maps provide information about how individual students relate concepts to form organised conceptual frameworks; (iv) Long-term difficulties with specific concepts are able to be traced. These findings are discussed with regard to results of other studies as well as to their implications for the teaching of mathematics in the classroom.  相似文献

教学信息化与教学理念革新   总被引:2,自引:0,他引:2  
现代化信息技术改变了人们对阅读、写作和计算的认识,对教育革新带来了几乎无尽的可能性。教学过程的信息化是新技术与新观念相互作用的过程。教学信息化对教师、学生角色的冲击为树立正确的教学信息化观念提出了迫切要求。应用现代化信息技术深化教学改革,首先要树立正确的教育信息化观念。  相似文献

“话题”(Topic)是和“述题”(Comment)相对的话语层面的概念,语义上的“有关性”(Aboutness)是话题和述题之间的基本关系属性。从词性上看,体词性或谓词性的句法成分都可以充当话题;从数量上看,话题可以不止一个。话题是“准话题”(Further-topic)的现实表现。“话题”和“焦点”(Focus)是从不同的语用层面进行的分类,两者可以在信息新旧度上建立起一个由旧到新的连续统。  相似文献
