研究训诂学必须贯彻联系性原则。所谓联系性原则,就是要坚持辩证法的观点,不要孤立地研究词义。这有两方面的涵义:一是要把词义的解释研究同音韵学、字学、语法学、修辞学等有关学科联系起来;一是要把词义的研究与化历史联系起来。  相似文献

Due in large part to the trends towards economic globalization, English has become the most widely disseminated and ubiquitous international language. The purpose of the study was to investigate what Taiwan’s EFL teachers at the elementary level believe about the policy of English as a compulsory subject and how they perceive the benefits and obstacles of the policy’s implementation. Ten elementary English teachers in Tainan City and its suburban areas participated in this study. Data were collected through teachers’ interviews, classroom observation and document analysis. Results found that all ten teachers agreed with the policy for English as a compulsory subject at the elementary level. They observed both positive and negative sides of this top‐down policy. Classroom observation and interview data revealed that EFL teachers had to plan their English classes with the constraints on a large class of students with mixed levels of proficiency, limited teaching hours and resources. Parents’ expectations of and attitudes towards English learning also became an obstacle.  相似文献

要提高学生的写作能力,需要长时间的练习,这也是一个循序渐进的过程。小学低年级主要进行的是写话训练,到了三年级,才开始尝试写作。写话训练是写作的基础,两者之间有着必然的联系,需要有效进行衔接。教师要思考如何更好地进行写话训练,以有效对接写作教学。文章结合教学实践,对写话训练与写作教学有效衔接进行论述。  相似文献

ABSTRACT

The demands on mathematical problem-solving have increased in almost all school systems internationally and may constitute a barrier for children with special educational needs (SEN). This study explored the role of fluid reasoning (FR), working memory (WM) and complex executive function of planning (EF) in children (N = 62) referred for assessment of SEN, and specifically of risk for mathematical difficulties (MD). Performances on FR, WM and complex EF of planning were used to predict risk for MD. Results showed that planning ability predicted children at risk for MD, beyond FR or WM ability, when comparing with children not at risk for MD. It was concluded that assessing the complex EF of planning in addition to FR and WM ability is crucial in identifying children at risk for MD. The importance of understanding how planning ability affects children’s mathematical problem-solving is discussed, in relation to assessment and teaching practices.  相似文献

High-School Students' Attitudes Regarding Procedural Abstraction   总被引:1,自引:0,他引:1  
During the last decade a new computer science curriculum has been taught in Israeli high schools. This curriculum introduces CS concepts and problem-solving methods independently of specific computers and programming languages, along with the practical implementation of those concepts and methods encountered in actual programming languages. The advanced study unit of the curriculum, Software Design, introduces the students to various aspects of software systems design through the use of abstract data types (ADTs). One main goal of the unit is to develop abstract thinking skills and problem-solving abilities. More specifically, the unit presents principles such as procedural abstraction, data abstraction, information hiding, modularity, efficiency, and reuse of code.We present the results of a preliminary study whose aim was to assess students' attitudes regarding procedural abstraction. The research population consisted of high-school students who attended the Software Design course (beginners), and a control group of undergraduate CS students (advanced). The results of the study clearly indicated a significant difference between the attitudes of the two groups. We found that the advanced students preferred algorithms that were formulated to some extent with high-level abstraction; however, they encountered a cognitive barrier when dealing with algorithms that they had evaluated as too abstract for them. However, beginners felt more comfortable with algorithms with low-level abstraction. Nevertheless they showed open-mindedness toward some degree of procedural abstraction. The results of the study were used to design scaffolding problem-solving tools for algorithm development, utilizing procedural abstraction techniques that can be adapted to various student populations (Haberman, B. (2002) SIGCSE Bulletin, 34(4), 60–64).  相似文献

《水浒》所表现的主旨一直被人们误读,其实,在“官逼民反”、“替天行道”、“忠义双全”等旗号下,是吏胥、军官和地主等统治阶级的中下层集团纠合流民和市民势力发动的一次争取权力的斗争,对封建政权并没有形成真正的冲击,而“八方共域,异姓一家”也只是虚幻的表象。  相似文献
