例题教学是数学课堂教学的重要组成部分,在目前的例题教学中,由于教学任务紧,教学内容多,教师往往把例题草率处理,这样做使得学生偏重于记忆一些方法和发展一些具体技能,而不是高层次地思考。理论和实践证明,从例题变式的视角展开教学活动,正确处理例题的变式与课堂教学的关系,才能让教师的教与学生的学产生质的飞跃。例题变式教学已经成为初中数学课堂教学改革的一个风向标。
The example teaching is an important part of the mathematics classroom teaching. In the current example teaching, because the teaching task is tight and the teaching contents are numerous, the teachers tend to deal with the examples in a hasty manner. In doing so, the student pays more attention to memorizing some methods and developing some specific skills. Not a high-level thinking. Theory and practice have proved that teaching activities can be started from the perspectives of the examples and the relationship between the examples and the classroom teaching can be correctly handled so that the quality of teaching and student learning can be leapfrogged. Examples of variant teaching has become a junior high school mathematics classroom teaching reform a benchmark.
