新《课程标准》指出:数学教学是数学活动的教学,是师生之间、学生之间交往互动与共同发展的过程。数学课堂需要活力,没有活力的课堂,任教师用华丽的语言,再动听的语调,也不会打动学生的心灵,震撼学生的灵魂;没有活力的课堂,任教师用再先进的现代教学手段,也只是徒具其形,苍白无力;没有活力的课堂,教师不再年轻,学生不再生动。因此,在数学课上,教师要有意义地设计让学生感兴趣的学习情境来调动学生的内驱力,撬开学生智慧的大门,让数学课堂充满活力[1]。
The new “Course Standard” pointed out that mathematics teaching is the teaching of mathematics activities and is the process of interaction and mutual development between teachers and students and between students. The mathematics classroom needs vitality. There is no dynamic classroom. If the teachers use gorgeous language, then the tone of the melodious sound will not impress the students’ hearts and shake the soul of the students. There is no dynamic classroom, and teachers will use advanced modern teaching methods. It’s just a matter of fact, pale and powerless; in a classroom without energy, teachers are no longer young and students are no longer vivid. Therefore, in mathematics classes, teachers should meaningfully design learning situations that are of interest to students to mobilize the internal drive of students and open the door to the wisdom of students, so that the mathematics classroom is full of vitality [1].
