在高中数学课程中,数学归纳法并不是一个“教师容易教,学生容易学”的单元.在教学实践中,教师们往往迫于教学进度的压力,在学生尚未领会这个方法的精髓时,就提供复杂多样的题目供学生练习,“两个步骤一个结论”的格式套用成了教学的重点.至于学生对数学归纳法原理是否理解,往往得不到足够的 In the high school mathematics curriculum, the mathematical induction is not a unit of “teachers are easy to teach, students are easy to learn.” In teaching practice, teachers are often forced by the progress of teaching pressure, when the students have not yet understood the essence of this method , To provide complex and diverse topics for students to practice, “two steps a conclusion ” format applied as the focus of teaching as to whether students understand the principle of mathematical induction, often not enough
