动态几何题是中考的热点题型,“动”已成为中考眩目的亮点。但由于动态几何题的教学难度较大,学生往往十分畏惧解答这类题型,教师在教学解题思路时也受到限制。而几何画板具有数学视觉化和动态化的功能,能够提升此类问题的教学效果,有助于培养学生的分析能力和想象能力。本文以动态几何题中重叠图形面积的计算为例,探讨利用几何画板如何提升解题教学的效率。
Dynamic geometry is a hot test questions in the exam, “move ” has become a dazzling bright spot in the exam. However, due to the difficulty of teaching dynamic geometric problems, students are often very afraid of answering such questions, teachers are also limited in teaching solutions to problems. The geometrical drawing board has the function of mathematics visualization and dynamicization, which can improve the teaching effect of such problems and help to develop students’ analytical ability and imagination ability. In this paper, the calculation of the area of overlapped graphics in dynamic geometry is taken as an example to explore how to improve the efficiency of problem-solving teaching by using geometry drawing board.
