Problem-based Learning In High School Biology Teaching In The Practice And Thinking

China's current education status is on the one hand, the community's desire for creative talent, on the other hand, the lack of awareness of the problem. Therefore, we must be on education teaching methods, teaching strategies for reform, the problem of awareness training students suspected spirit and the spirit of innovation.The study based on problem, referred to PBL, is a mainly to solve the problem of teaching mode. This reform of teaching in foreign countries has been fruitful, that it will also provide China's reform a new teaching methods and ideas, and make valuable resultsBased on the theoretical study and teaching in high school biology in practice, this paper try to make a modest force in exploring a Chinese characteristics suitable for the high school biology teaching model. At the same time, Hope played "Paozhuanyinyu" the role of lead more teachers into the teaching of the new model, so that our high school biology curriculum reform the true sense of implementation, rather than a mere formality. By using literature, experimental research, Comparative Study of Law and action research method based on comprehensive research, the theory of learning has been explored.The practice of research papers are part of photosynthesis and respiration for the case, the teaching process PBL made all-round display. The case set up for students of the problem is that Africa's food shortage problem, given to African students will soon send a senior agricultural experts role to the students task is to develop a raise in agricultural production in the crop yield of specific measures which Students carry out independent, collaborative problem-based learning. Through issue-based learning, students have the flexibility of photosynthesis and respiration, and other knowledge and in real life applications, and to develop awareness of the problem of the students, the habit of critical thinking, the development of a self-study and solve practical strategy Problems.Finally, the practice of the results of the PBL teaching model shows it is worth trying in the high school biology teaching reform.
