运动变化类的试题是各地考试的热点之一,但由于初中学生习惯于静态问题的解证,对动态问题往往感到棘手,甚至束手无策．为适应课程改革的要求和学生数学素质的提高,在教学中必须注意挖掘动态问题,有计划、有目的地安排一些运动变化类的习题,以拓宽学生的视野,达到培养学生分析问题和解决问题的能力的目的．本文就动态题的题型及解法作初步探讨．
The test of sports variation is one of the hotspots in local examinations. However, because junior middle school students are accustomed to the verification of static problems, they often find it difficult to deal with dynamic issues, and they are even helpless. In order to meet the requirements of curriculum reform and the improvement of students’ mathematics qualities, we must pay attention to mining dynamic problems in teaching, and arrange some kinds of exercise changes in a planned and purposeful manner so as to broaden students’ horizons and achieve students’ problem analysis and problem solving. The purpose of the ability. This paper makes a preliminary discussion on the questions and their solutions to dynamic questions.
