| In modern times, the development and reform of education has become the important strategy of many countries facing with ever increasing international competition. Now science and technology is developing dramatically, the products of technology are prevailing, and the cycle of intellective aging is shorted faster. The core of international competition is the competition of talents. It is impossible for the most excellent teacher to pass on all knowledge to students, especially nowadays. So teaching knowledge is limited, and teaching how to think is essential. A teacher should be the guide of creative thinking. Therefore, education is not merely teaching knowledge, but teaching how to study, how to think and how to think creatively is more important.Based on research of many documents and teaching practice, I have explored anew teaching model of experiment-----Model of twice experimental method, inorder to solve many problems in biology experimental teaching. The model undergoes several stages: studying of theory, first confirming experiment, second exploring experiment and evaluating experiment. The characteristics of the model are fundamental, creative, feasible and easily accepted.The aim of this thesis on designing "model of twice experimental method" is to find a new method which not only combines the advantages of traditional teaching and present exploring education, but also overcomes their disadvantages in the light of advanced teaching theory. Through the proof of theory and practice, this new method is an effective way to develop students' creative thinking.In my thesis, I firstly illustrate the necessities of teaching reform about biological experiment based on the analysis of the current educational situation and the relationship between experiment and accomplishment education. Secondly, I analyze this new method theoretically (including the theoretical base, the specific procedures, noting items and applied range and so on.) and compare the new...
