《数学课程标准》中明确指出,“要让学生在生动具体的情境中学习数学。”[1]小学数学不会自发产生与现实生活的联系。运用数学知识和方法解决一些简单的实际问题,需要采用切实可行的方法。针对小学生教育实际,巧妙设计适合小学生特点的数学教学情境,通过实物演示、角色扮演、实验操作和多媒体等多种手段创设课堂教学情境,对于调动学生学习主动性、积极性和创造性,提高学生的参与度具有重要意义。
“Mathematics Curriculum Standard” clearly states that “let students learn mathematics in a vivid and specific context.” [1] Elementary mathematics does not spontaneously produce a link with the real life. The use of mathematical knowledge and methods to solve some simple practical problems requires the adoption of practical methods. According to the reality of pupils ’education, we design the situation of mathematics teaching which is suitable for pupils ingeniously and create classroom teaching situations through many kinds of means, such as demonstration, role playing, experiment operation and multimedia. It is of great importance to mobilize students’ initiative, enthusiasm and creativity in learning and to increase their participation Degree is of great significance.
