我原来教《植物的茎》这一课,采用的教学方法是,先采集几株植物标本放在讲台上,上课时,我分别拿起不同的植物,指着植物茎的部分向学生介绍讲解。我讲得很详细,生怕学先听不懂,结果,学生虽然知道植物有茎这个部分,但要他们具体现说茎的位置,有些学生就有点模糊不清。有几个学生竟把不属于茎的部分也说成是茎。 I originally taught “plant stems” this lesson, the teaching method is to collect several plant specimens collected on the podium, class, I picked up different plants, pointing to the part of the plant stem to explain to students . I talked in great detail for fear of learning to understand first. As a result, although students knew that plants had stem parts, they were somewhat ambiguous when asked to specify their position. There are several students who actually say that the part that does not belong to the stem is also the stem.
