通过一节新课“反比例函数”(北师大版九年级上册第五章第一节)的内容制作教学课件,使我深刻地体会到了信息技术在数学课堂教学中的灵活性、直观性。制作起来比较麻烦,但能使课堂教学达到预想不到的效果。课后仔细回味,从教学设计到课堂教学觉得有很多值得反思的地方。一、教学设计备课时,我认真研读教材,认为本节课无论是重点和难点都要让学生掌握反比例函数的概念,以及如何与一次函数及一次函数中的正比例函数的区别。所以,我在讲授新课前安排了对“函数”
Making teaching courseware through the contents of a new lesson “Inverse Function ” (Beijing Normal University version of the ninth grade on the fifth chapter first) made me deeply understand the flexibility of information technology in mathematics classroom teaching, intuitive Sex. Produced more trouble, but can make classroom teaching to achieve the desired effect. After class aftertaste, from teaching design to classroom teaching there are many worth reflecting on. First, teaching design lesson preparation, I carefully study textbooks, that this lesson, both focus and difficulty should allow students to master the concept of inverse function, and how the function and the primary function of a proportional function of the difference. So, I arranged a new class before the “function”
