《植物的根》一课是小学自然三年级教材,认识直根和须根是本课一个重点,以往的教学,我习惯于让学生观察各种各样的根后,直接告诉学生科学规范的名字,孩子们虽然记住了,可我老觉得缺少点什么。 The “root of plants” lesson is the third grade natural primary school textbooks, know straight roots and fibrous roots is a key focus of this lesson, I used to let students observe a variety of roots, the students directly to the scientific norms name Although the children remember, but I always feel missing something.
