The Reflection And Case Designs On Life Oriented In High School Chemical Teaching

It is the current focus of international education reform for strengthening the links between courses and student life, as well as scientific and technological development of modern society. As an important goal for new high school curriculum reform in china, which can meet the diverse development needs.In order to carry out reformational teaching idea of the new chemisty curriculum, educators should establish the bridge of chemical education and life. The penetration of life-oriented teaching in high school chemistry education has important theoretical and practical significance.This paper firstly analyzed the development statue of chemical life-oriented teaching at home and abroad. Secondly, through investigating teachers and students, the paper find the current situation about life-oriented teaching in high school chemistry teaching applications. Thirdly, collected and analyzed the life-oriented teaching concent in high school chemistry. On these basis, In combination with the principles,theoretical basis and the present situation of the life-oriented teaching, this paper exploe the implentation teaching strategies and put forward several ways to permeate life-oriented teaching in high school chemical class: in classroom teaching, experiment teaching and extracurrcular practice, and give four case designs:(1)the class teaching, amount of substance in the chemical experiment(class 1).(2)Laboratory activities,the test of protein and calcium in tofu and iodine in kelp.(3) protein and calcium in green chemistry activity, homemade improvised teaching aid.(4) the extracurricular practice exploration case, made fruit battery. The facts show that the life-oriented teaching strategies in high school chemistry can greatly stimulate the motivation of students to learn chemistry, help students gradually to learn to analyze and solve the practical problems.Finally, I develop the experience and suggestion for the study. I hope it can provide reference for teachers' teaching and improve students' scientific literacy by the experience and suggestion.
