The classroom of science class is a classroom full of problems. In class, students come into the classroom with problems and get out of the classroom with new problems. They are trained and developed in solving problems. Group discussions are carried out around a wide variety of issues.

(2) to some key problems which are easily neglected, we can set up problems in time to arouse the attention and thinking of students, and to cultivate their precise and rigorous scientific spirit. (3) in summary, set some comparative or inductive problem, a concept, to help students to better distinguish between similar or related to summarize the rules and the nature, to cultivate students respect for evidence of scientific literacy, improve the students reasoning ability analysis. Two, discussing habits is a powerful guarantee for effective discussion. A good discussion habit should be taken from the lower grades to achieve the best results. Low grade students especially love to discuss learning, but often not cooperative learning, more difficult to effectively carry out their study, in the group discussion is easy to forget the self restraint, or to let things drift; self-centered, love to do hero; or in view of the lack of scientific basis for discussion; and or discuss easily in the pr
