教师“沉”下去的重点是学生能叙述的教师不替代,学生能操作的教师不示范,学生能发现的教师不暗示,学生能提问的教师不先问。让学生在“动”中学会评价,学会求知,学会交往。 Teachers “Shen ” go down the focus is not to replace the students can be described in the teacher, the students can operate the teacher does not demonstrate the students can find the teacher does not imply that students can ask questions without first asking. Let students learn evaluation in “move ”, learn to know and learn to interact.
