在高中数学学习过程中,创造性思维、多变思维非常重要,在解决数学题目的时候,一定要注意多变思维的运用,“一题多解”不仅可以提高学生学习数学的兴趣,而且可以帮助学生从不同侧面、不同角度去思考问题,培养良好的解决问题的习惯,拓展学生的视野。下面就学生在学习了正余弦定理解三角形之后的一道习题,从多角度分析,给出不同的解法,说明课堂教学中应注意充分用一题多解,培养学生思维。
In the process of high school mathematics learning, creative thinking and changeable thinking are very important. When solving the mathematics problem, we must pay attention to the use of changeable thinking. The problem of “solving a problem with multiple answers” not only can improve students’ interest in learning mathematics, but also Students can help students think from different aspects and from different perspectives, cultivate good habits to solve problems and expand students’ horizons. The following students learn the sine cosine is a solution to the problem after the triangle, from a multi-angle analysis, gives a different solution, that should be fully utilized in classroom teaching should pay attention to more than one solution to develop students’ thinking.
