锐角三角函数作为初中数学中重点教学内容,掌握好该知识点不但有助于学生取得良好成绩,同时更重要的是能够为其今后更高层次几何学习奠定坚实基础,为此这就要求广大教师必须做好该方面教学.然而结合笔者实践来看,由于受到诸多因素所影响,当前锐角三角函数教学效果普遍不佳,如此一来不但严重地影响教学质量,同时更会对后续三角函数教学任务有效开展造成极大的阻碍,对此教师必须认清该知识点的重难点,紧抓学生常见认识误区和思维障碍,采取有效策略进行 Sharp-angle trigonometry as the focus of junior high school mathematics teaching content, mastering the knowledge point will not only help students achieve good grades, but more importantly, to its future higher level geometry to lay a solid foundation, which requires the majority of teachers However, according to the practice of the author, due to many factors, the current acute trigonometric trigonometry teaching effect is generally poor, so not only seriously affect the quality of teaching, but also on the follow-up trigonometry teaching tasks Effectively carry out a great obstacle, this teacher must recognize the heavy and difficult points of knowledge, grasp the common misconceptions and thinking obstacles students to take effective strategies
