追问是科学课堂教学中对话策略的组成部分。为了使学生弄懂弄通,教师往往在一问之后再次提问,穷追不舍,直到学生能正确理解为止。追问本身不是目的,只是引导学生进一步深入理解问题的手段。科学课堂教学中,不断生成新问题,需要教师根据学生的答问、讨论等学习活动的展开,对学生的思维进行即时的疏导、点拨。 Questioning is part of the dialogue strategy in science classroom teaching. In order to get the students to get things done, teachers tend to ask questions again after a question, chasing after, until the students can understand correctly so far. Questioning is not an end in itself, it is just a means of guiding students to further understand the issue. In the classroom teaching of science, new problems are constantly emerging. Teachers are required to conduct immediate learning activities based on students ’questions, discussions and discussions, and to promptly guide and direct the students’ thinking.
