要培养学生编应用题的能力,必须重视把数学表达式转化为数学语言,再把数学语言转化为文字叙述。下面就如何进行“两个转化”的教学谈几点认识和体会: 一.重视教学表达式和数学语言间相互变化在教学中,让学生用不同的数学语言表达同一算式,不仅可以使学生加深对基本概念,术语和运算符号的理解,而且可以培养学生运用数学语言准确地表达数量关系的能力(同时也培养了学生的口头表达能力),从而也就为培养学生编应用题的能力奠定了基础。如在进行乘法算式的教学中,让学
To train students' abilities in compiling questions, we must attach great importance to converting mathematical expressions into mathematical languages and then turning mathematical languages into written narratives. The following on how to carry out the “two transformations” of teaching to talk about some understanding and experience: One. Emphasis on teaching expression and mathematical language mutual change In teaching, allowing students to use different mathematical language to express the same formula, not only can make students deepen The understanding of basic concepts, terminology, and operator notation also fosters students' ability to use mathematical language to accurately represent quantitative relationships (and also to develop students' verbal communication skills) and thus to develop students' ability to compose questions basis. As in the teaching of multiplication formula, let's learn
