我覺得幾何教學有兩點應經常引起我們的注意,那就是: 1.培養學生正確地認識圖形,運用幾何知識解决一些實際問題。 2.引導學生對圖象的積極觀察,積極思維,從而啓發與培養其邏輯推理的能力。所以我講解梯形時,採取了下面的教學方式進行。 (1) 通過實例,導出定義,舉例如下: 1.我國民族形式所謂“八字門牆”的建築,在地面上的構圖是怎樣的形狀? 2.延伸於原野上的鐵路、公路的路基,其横

Instruct students to actively observe and positively think about images, so as to inspire and develop their ability of logical reasoning. So when I explained the trapezoid, I took the following teaching method. (1) Derive definitions through examples, as follows: 1.
