一、激发学习兴趣,树立正确的数学观教师在教学中适当穿插数学史的教学,在课堂上讲点趣闻轶事,能极大地提高学生学习数学的积极性,起到意想不到的效果。以下是我讲授八年级(上)平方根的一个片断。师:同学们,今天在新课前我想先给大家讲一个故事,好不好?生:好(兴奋)。师:(幻灯片展示)大约公元500年前,在遥远的古希腊,有一位伟大的数学家,他的名字叫毕达哥拉斯。毕在数学上的重大贡献是发现了勾股定理,揭示了直角三角形三
First, to stimulate interest in learning and establish a correct mathematical view Teachers in teaching proper interspersed teaching of history of mathematics, anecdotes in the class to tell anecdotes, can greatly enhance the enthusiasm of students to learn mathematics, played an unexpected effect. The following is a part of the square root of my eighth grade (above). Teacher: Students, I want to tell you a story today before the new class today. OK? Teacher: (Slideshow) Around 500 AD, in ancient Greece, far away, there was a great mathematician whose name was Pythagoras.
