在新课程标准的基本理念中提倡实现信息技术与课程内容的有机整合,提倡利用信息技术来呈现以往教学中难以呈现的课程内容,加强数学教学与信息技术的结合,鼓励学生运用计算机等进行探索和发现。从近几年的高考命题来看,更加注重对学生能力的考查,利用图像解题成为高考的一个热点,如零点问题常用图像解决。我们在讲解这种问题时,传统的“直尺+粉笔”已不能满足教学的要求,手绘图不仅速度慢而且精确度不高,有时会把学生导入误区,解答不准确,特别是有
The basic concept of the new curriculum standards to promote the realization of the organic integration of information technology and curriculum content, promote the use of information technology to render difficult to present in the teaching of course content, to strengthen the combination of mathematics teaching and information technology, to encourage students to explore using computers And found. In recent years, college entrance examination proposition point of view, pay more attention to student ability test, the use of image problem-solving as a hot college entrance examination, such as zero point commonly used image solution. When we talk about this kind of problem, the traditional “ruler + chalk ” can not meet the teaching requirements, hand-drawing is not only slow and not accurate, and sometimes students will be misunderstood, the answer is not accurate, especially in the
