椭圆是最常见的曲线之一,椭圆的教学活动是平面解析几何的重点内容,有关椭圆的教学研究也是我们经常关注的课题.在此,谈谈本人采用“实验为先导,猜想作主线”方式进行椭圆教学的实践与思考,敬请同行专家指教.1　关于椭圆第一定义的教学教材(指人民教育出版社出版的高级中学教材 The ellipse is one of the most common curves. The teaching activity of the ellipse is the key content of the plane analytical geometry. The teaching research on the ellipse is also a topic that we often pay attention to. Here, I talk about using the “experiment as the guide, guess as the main line” method. The practice and thinking of elliptical teaching, please consult with peer experts. 1 teaching materials on the first definition of the ellipse (refer to the high school textbooks published by the People’s Education Publishing House
