材料:

种子的萌发 教师课前要求学生收集一些种子萌发的资料,或者向家长了解“春种”时农民要做的事。上课时,在复习种子的结构后,教师请学生谈谈“春种”时农民要做些什么,并请学生把在家萌发的种子拿出来展示。教师发现有个别组没能拿出成果.让他们谈一谈原因,有个别组说他们在做实验时水放少了,有个别组说不出原因。此时,教师启发学生思考为什么有些组的实验成功了,而有些失败了,使学生意识到种子萌发需要一定的条件.教师鼓励学生猜测种子萌发可能需要什么环境条件。 大多数学生猜测种子萌发需要水、空气、光照、肥料、土壤等。教师选择“种子的萌发需要充足的水”引导学生设计实验方案。通过讨论,教师引导学生认识对照实验法.播放一段种子萌发多组对照实验录像,给予学生提示。然后请各组学生运用对照实验法设计其他条件的实验方案。课后执行实验方案。

问题: 作为一名教师,在这种学习活动实施阶段应做些什么工作?

Product Description
      In the 150 years since the publication of Origin of Species, Charles Darwin has been considered between
two extremes-a great biologist or heretic (持异端学说者). However, the truth is much more difficult to
understand than that. In any case, Darwin's theory of evolution and natural selection had the greatest influence
in history.
      In The Darwin Myth, author Benjamin Wiker offers a full-side analysis of Darwin's theories as well as the
social, scientific, and religious effect of his work. Scientists often cause debates (争论) that will last for
generations for their new theory. Still, no scientist has caused more debates than Charles Darwin. To some
he is the revolutionary "father" of evolution. To others his theory of evolution unconsciously disagrees with
many ideas in modern eugenics. (优生学) In The Darwin Myth: The Life and Lies of Charles Darwin, author
Benjamin Wiker will make them clear.
Contents
