在高中数学的各类考试当中,都可以发现应用问题的影子。应用问题所占比重的稳步递增,向我们发出了两个信号:一是强调高中数学教学的重点所在,即要注重理论知识向生活实践的迁移,强化学生学以致用的能力;二是启发课堂教学开展的全新途径,以生活元素的引入更好地引发学生们的学习热情。发现生活中的三角知识,引发数学学习热情在很多学生的印象里,三角知识都是以数字和公式为主体的,似乎一谈到三角,就只有各种图形和计算。其实,三角的知 In the various high school math exams, you can find the shadow of the application of the problem. The steady increase in the proportion of application problems sent us two signals: First, emphasizing the emphasis of high school mathematics teaching, that is, paying attention to the transfer of theoretical knowledge to life practice and strengthening students’ ability to apply what they have learned; second, Teaching a new way to the introduction of life elements to better arouse students enthusiasm for learning. Triangular knowledge found in life, triggering the enthusiasm for learning mathematics In many students’ impression, trigonometry knowledge is based on numbers and formulas, it seems that when it comes to the triangle, there are only a variety of graphics and calculations. In fact, the triangle of knowledge
