数学课程的一个任务,就是培养学生在数学学习过程中,对用符号表示数及其运算的理解和感受。数学符号是具有简洁性和抽象性的规范语言.它准确、清晰,具有简约思维、提高效率、便于交流的功能。罗素说过:“什么是数学?数学就是符号加逻辑。”可见.培养学生的符号感对于数学语言表达思想具有重要的意义,也是发展学生思维的需要。一、让学生感到引入符号的必要数学符号的引入,可简短地表示和反映数量关系与空间观念中最本质的属性,并推进数学的发展。因此,在教学中应当生动地展示这种青境,让学生感到引入符号的必要性,并从中体验到优越性,从而
One of the tasks of maths course is to train students to understand and feel the number of symbols and their operation in mathematics learning process. Mathematical notation is a normative language with conciseness and abstraction, which is accurate and clear, has simple thinking, improves efficiency and facilitates communication. Russell said: “What is mathematics? Mathematics is the symbol plus logic.” It can be seen that cultivating students ’sense of symbol is of great significance to the idea of mathematical language expression, but also the need to develop students’ thinking. First, letting students feel the introduction of the necessary mathematical symbols to introduce symbols can briefly represent and reflect the most essential attributes of quantitative relations and spatial concepts and promote the development of mathematics. Therefore, in teaching, this kind of green environment should be vividly displayed so as to make students feel the necessity of introducing symbols and experience the advantages from them
