High School Chemistry Classroom The Situational Teaching Practice

New "Chemistry Curriculum Standards" puts:teaching students should pay attention to existing experience, and let them live in familiar situations in order to feel the importance of chemistry learning; teachers should be good at guiding students to find problems in the real situation, discuss them in a targeted manner and come up with ideas to solve problems to enable students to develop their recognition gradually. Situational teaching process is to meet the academic requirements of a teaching method.In this paper, constructivist learning theory and the theory of modern teaching theory are used as the main basis for the high school chemistry to explore how to collect material, process material situations, and create teaching situation in different ways according to the characteristics of situation. Making use of a questionnaire survey, interviews and classroom practice, combined with the method quasi-experimental style of teaching in chemistry, the thesis explores students' interest in teaching, student awareness of the problem, problem solving ability and academic impact in chemistry situations.The thesis is divided into four parts. The first part introduces the research background, purpose, ideas, methods, and reviewed the situation teaching and research profiles at home and abroad; the second part identifies the connotation of the context, teaching situations, then describes and summarizes the situations of the type of chemistry teaching and theory base; The third part explores and summarizes the basic procedures and approaches in the creation of situational teaching in high school chemistry class. Also, the author lists a number of cases the implementation of situational teaching; and analyses the effects of contextual teaching. The last part involves conclusions and reflections.The results show that:in Chemistry, reasonable and properly creating teaching situation can improve the level of student interest in chemistry learning, so students can be effective in finding problems, analyzing and solving problems, but also conducive to the improvement of academic performance; At the same time chemistry teachers are also put forward higher requirements.
