Teaching Research On The Principle Of Chemical Reaction In High School Based On STSE Perspective

STSE (scientific, technical, social and environmental) education in Western education in order to meet the great scientific innovation, rapid development of technology and the progress of society and recognize that these are the environmental problems, and made education a major reorganization. Faced with such shocking worldwide educational innovation, coupled with China's traditional education itself has defects, and in recent years, frequent ecological and environmental problems, education reform is very important.High school chemistry is further research on the junior high school chemistry knowledge learned, it aims to help students understand the principles of chemistry discipline, basic properties of matter, as well as the substance of different responses and the like. Essence of "chemical reaction principle" module involved in a chemical reaction, the reaction in the process of change in the energy, chemical reaction rate, pH of the solution knowledge and electrochemistry, have great value in the production of life-such as said that the development and rational use of energy, the clever use of a catalyst, soil pH control cell development and metal corrosion, and so a lot of the actual process. So for the study "chemical reaction principle" elective module, not only to the importance of knowledge of the principles of learning, but also pay attention to the practical application of knowledge. Therefore, based STSE perspective of teaching "chemical reaction principle" module, opened up a new "chemical reaction principle" teaching approach to STSE teaching content scenarios material, effectively stimulate students' motivation to learn and improve learning initiative, thereby enhancing the the effectiveness of teaching, curriculum standards to achieve three objectives proposed, which reflects the true value of education.Herein by reference in English literature, part of the theory of STS education. Through PEP elective 4 "chemical reaction principle" teaching system induction, analysis college entrance examination questions, the integration of rich STSE teaching resources which penetrated, describes teaching strategies, writing instructional design and apply it to specific teaching practice. Specific study includes five aspects:The first part "Introduction", from starting the trend of social development analysis, as well as the characteristics of "chemistry principle" elective module, explains the importance of teaching from STSE perspective. As well as finishing the current research related issues, he explained the significance of the research and the main methods.The second part "STS education theory" of STS educational goals and basic content of the presentation made plain, and meet with high school chemistry teaching to do a simple analysis, which proposed a "chemical reaction principle" based STSE teaching perspective design, and describes the corresponding teaching strategies.The third part "STSE teaching content," mainly for the past five years, the volume of chemical entrance of the New Curriculum and the national title PEP "chemical reaction principle" Infiltration has STSE teaching content and subject knowledge collate, reflecting in STSE perspective the importance of teaching.Part IV, "based STSE perspective of chemistry "Course Design", selected textbooks content representative, social, environment, science and technology as the creative scene, were carried out thematic and fragmented instructional design, Contact students real life, starting from the actual experience of students, fully embodies the principle of student activity center.The fifth part chemical reaction principle "based on STS perspective" "experiment and analyze the results of teaching," by the same teacher in the same level of two classes, teaching experiment, using paper and pencil tests to collect data, and the use of Marco Cardiff chain analysis, teaching effectiveness were evaluated.Part VI, "conclusion", according to the trends of education reform and the characteristics of "chemical reaction principle" teaching content, the author describes the main points of the proposed Institute and areas for improvement, after the desired direction for future efforts.STSE perspective based teaching "chemical reaction principle" module conforms to the trend of education reform I had, but also conducive to the master, to improve the scientific knowledge of the practical ability of the students, greatly improving the effectiveness of teaching.
