数学课程标准指出,数学教学过程是教师引导学生进行数学活动的过程,是教师和学生之间的互动过程,是师生共同发展的过程,是一个不断生成问题、不断解决问题的过程.随机生成的数学课堂,有利于激发学生的学习兴趣,有利于学生掌握知识、培养思维能力和创新能力,也有利于促进教师的专业成长.教师经常会精心预设,从司空见惯的生活中,找到问题原型,让学生喜爱质疑,乐于探究,找到问题答案.有的课堂上,经常会出现教师没有设计到的问题,这就是课堂的随机生成,这种意外资源正是课堂的亮点,也考验教师的应变能力.
The standard of mathematics curriculum points out that the process of mathematics teaching is the process of teachers guiding students in mathematics activities, the interaction between teachers and students, the common development of teachers and students, the process of continually generating problems and solving problems. Of mathematics classroom, is conducive to stimulate student interest in learning, is conducive to students to master knowledge, develop thinking ability and ability to innovate, but also conducive to promoting the professional growth of teachers.Teachers often carefully preset, from the commonplace life, find the prototype of the problem , So that students like to question, willing to explore and find the answer to the problem.In some classrooms, teachers often do not have the problem of design, which is generated randomly in the classroom, this unexpected resources is the highlight of the classroom, but also to test the teacher’s response ability.
