指导学生正确地运用数学语言有助于学生透彻理解知识、正确运用知识,也有助于发展学生的逻辑思维和简明有条理地口头表达的能力。怎样教学生掌握数学语言呢?我平时注意到以下几点: 一、讲清词义。要求学生掌握精炼的数学语言,首先要使他们透彻地理解有关的名词术误的含义。我常借助直观教具,通过观察、讲述逐步提炼、概括,说明名词术语的意义。例如讲解“分数的意义”,必须使学生弄懂“单位一”、“平均”“若干份”、“一份或几份”等关键词语的意思。教学时,让学生观察一个圆形、一个正方形、一个长方形、一个直线段,再分别把它们平均
Guiding students' correct use of mathematical language helps students to thoroughly understand and use knowledge correctly. It also helps students to develop their logical thinking and concisely and verbally. How to teach students to master mathematical language? I usually noticed the following points: First, make clear the meaning. Asking students to master the refined math language first requires them to thoroughly understand the misleading implications of nouns. I often use visual aids, through observation, narration gradually refined, summarized, explain the meaning of terminology. For example, to explain the meaning of “scores,” students must understand the meaning of the key words such as “unit one,” “average” “several portions,” “one or more portions.” Teaching, let students observe a circle, a square, a rectangle, a straight line, and then respectively average them
