反思是人类特有的一种心智活动,也是人有意识地考察自己的行为及其情境的能力,它能使人们更清晰地理解自己的行为和行为后果,从而更理性、更有目的地开展活动。没有反思,学生的理解就不可能从一个水平升华到更高的水平。就中学生的生物学习而言,反思应指中学生对自己的学习活动过程的再思考与再审视,它既是一种思维形式更是一种学习习惯。 Introspection is a kind of mental activities peculiar to human beings. It is also the ability of people to consciously examine their own behaviors and situations. It enables people to understand their own behaviors and behavioral consequences more clearly so that they can conduct activities more rationally and purposefully. Without reflection, student understanding can not be sublimated from one level to a higher level. In terms of biological learning of middle school students, introspection should refer to secondary school students' rethinking and reexamining of their own learning activities. It is both a form of thinking and a learning habit.
