智能板涡旋。在小学的数学教学过程中，数学教师最头疼的是，学生很难理解和学会在数学中应用抽象问题，并且可以通过电子白板解决这个问题。例如，去年在我们学校举办的同一类异构活动，这位两位老师同时在六年级“放大和减少图形”中。两位教师都能够使用电子白板成功展示上下文，认知在活动中引入的引入，在探究中的创新，通信中的互补，升华反射，改进应用??等等。教学理念，课堂可以清晰，专注，难以实现有效的突破，实现预期的课堂效果。在课堂开始时，两位教师都创造了有效的情境介绍。差异是老师一个选择了同学的照片。通过使用电子白板的不同尺度功能，学生可以体验现实生活中的扩大。申请，揭示主题;另一位老师b介绍了他们唐小梅的校园的照片，利用序幕的功能逐渐向学生展示上课，让学生感到近距离，突然关闭教师和学生的距离，这部分老师的亮点 is not only to create the situation, but also to put the photo in the grid of the electronic whiteboard, through the question: the same is magnified, what is the difference? Let students naturally think of how much each side of the graph is enlarged in their minds, basically solving the difficult points of this lesson. In the expansion part of the class, the two teachers showed their magical powers. The same thing is that this is not just a pure math class. It can expand the students' horizons, embodying mathematics from life, and mathematics application and life. The difference is that Teacher A has collected a lot of pictures using the scale. For example, our Shenzhen World Window, the enlarged picture of the snowflake is beautiful, etc., and many beautiful pictures are designed to be displayed to the students gradually; Teacher B is expanding this aspect. The main focus is on the use of enlargement and reduction. The copying machine is enlarged by 200% and reduced by 50%. To design a beautiful picture into a newspaper held by the school, it needs to be scaled down according to a certain scale. The image slides stimulate the interest of students in the electronic whiteboard one by one.
