教育家杜威说过:“教师,一个引导者,他撑着船,学生用力地用浆把船划向前。”可见,教学过程关键要看学生是否‘用力’了,主动了,一旦主动学习了,那么就能达到理想的教学效果。《数学课程标准》提出,学生的数学学习活动应当是一个生动活泼的,主动的和富有个性的过程。实践证明,只有让学生主动、生动、轻松地学数学,学生的学习积极性才会不断提高,学习效率也会不断提高。那么,如何让学生主动、生动、轻松地学 The educator Dewey said: “Teacher, a guide, he holds the boat, students forcefully use the slurry to draw the boat forward.” Visible, the key to the teaching process depends on whether the students ’hard’ initiative, and once Take the initiative to learn, then you can achieve the ideal teaching effect. The Mathematics Curriculum Standard states that students’ math learning activities should be a lively, active and individualized process. Practice has proved that only by allowing students to take the initiative, vivid and easy to learn mathematics, student learning enthusiasm will continue to improve, learning efficiency will continue to improve. So, how to make students take the initiative, vivid, easy to learn
