针对数学课堂教学中存在的种种问题,我校数学组进行了《数学课堂教学的有效性》专题研究。下面我就这个研究专题,结合自己的教学实践,从情境的创设、教材的使用、学生的学习方式及练习的设计等几个方面,谈几点不太成熟的看法。一、联系实际创设情境创设有效的生活情境是提高数学课堂教学有效性的重要条件。如在教学“圆的面积”一课时,在课的开始,我用课件显示一幅图画:用绳子栓住一只羊,绳子的另一端栓在木桩上,羊绕着木桩运动形成一个圆。这个动画情境很快吸引了学生,学生就会很想知
In view of the various problems in the classroom teaching of mathematics, the mathematics group in our school conducted a special study on the effectiveness of the classroom teaching in mathematics. Here I talk about this research topic, combined with my own teaching practice, from the creation of the situation, the use of textbooks, student learning and practice design aspects of several less mature views. First, contact the actual situation to create an effective life situation is to improve the effectiveness of classroom teaching of mathematics an important condition. For example, at the beginning of the lesson, I showed a drawing using courseware: a sheep tied with a rope, the other end of the rope tied to a stake, and a sheep moving around a stake Form a circle. This animated scenario quickly appeals to students and students will want to know
