The Use Of Case In Junior Middle School Biology Teaching

This paper described the meaning of the case teaching method﹐advantages of the case teaching in biological disciplines﹐present situation and problems of the case teaching, applications of the case teaching in the teaching of biology in junior middle school, the effectiveness of the case teaching in junior middle school biology teaching,which can prove that it's feasible to carry out the case teaching in biology teaching in junior middle schools.By attempting to do experimental study about the case teaching of biology in junior high school we form the teaching method of students center, the main focus of students practice, and the aim of training students the quality of innovation, in particular the innovative spirit and ability ,which are the basic values of classroom teaching .we contrast two classes that are taught in case teaching method and in conventional teaching way .The statistical analyses are that, in the Pre-test, regardless of experimental group or control group in the focused class, or experimental group or control group in the ordinary class, the examinations average are not significantly different, outstanding rates and passing rates do not change. In the later test, in the focus class, experimental group contrasted with the control group, the average are significant different, In the ordinary class, experimental group contrasted with the control group, the average is of a very significant difference, outstanding rates and passing rates do changer, teaching effect is remarkable. Practice has fully proved that the results of the case teaching practice. Case Teaching way is useful to reform the traditional concept of teaching methods, is useful to improve students'interest , ability and marks. It is also useful to help students learn how to learn and explore, learn how to exchange and cooperate, learn application and innovation.
