Research On The Application Of Problem Teaching Method In Chemistry Teaching In Yunnan National Senior High School

Education should be geared to the needs of modernization,of the future.In order to conform to the development of the times,the new curriculum reform is being in process like a raging fire.Problem teaching method is a relatively mature teaching method which has been widely studied and developed in recent years.This method emphasizes the student-centered approach with the teacher combining the latest development area of students' cognition to create a targeted problem situation,so that students can independently mobilize multiple intelligence to actively participate in solving problems,and hence realize the meaningful construction of knowledge in the problem solving.This teaching method lays more emphasis on students' subjectivity,the process of knowledge acquisition and the development of students' personality and thinking.What students learn is not only knowledge but also the ability to solve problems.On the basis of elaborating the relevant theories and concepts of problem teaching method,this paper closely combines the characteristics of Yunnan nationalities high schools and students,and takes senior high school students as the research object.Through the consideration and integration of a large number of literature,this paper explores the problem teaching process which is applicable to Yunnan nationalities high schools,and this study implements the problem teaching method in senior one throughout the whole year.The selected textbooks are chemistry compulsory Bookl and compulsory Book2 of people's education press,and the teaching contents are divided into three knowledge modules:basic concepts of chemistry,inorganic chemistry,and organic chemistry.This paper is mainly divided into four parts.The first part is about problem posing and the current situation research,which mainly combs the educational background of the new curriculum reform and the research status of the problem teaching method at home and abroad.It aims to find the research direction of this paper and determine the research content and research methods.The second part is the definition of core concepts and theoretical basis for research.Through the accurate definition of the core concept of the problem teaching method,the most relevant theoretical basis of the problem teaching method is explored,that is,the constructivist theory.Based on the theory of constructivism,the characteristics and implementation process of the problem teaching method are proposed.The third part is the study of teaching practice.According to the knowledge category attribute,the knowledge in Book 1 and Book 2 is divided into three basic types:basic concepts of chemistry,inorganic chemistry and organic chemistry.By analyzing the characteristics of each type of knowledge,ideas and precautions are proposed for various types of knowledge when using problem teaching method,and provide typical teaching cases.The fourth part is the research conclusions and prospects.The results show that the influence of the problem teaching method on the students of Yunnan nationalities high school has the following five aspects:1 improving students'recognition of chemistry courses;2 improving students' participation in chemistry classes;3 promoting students' chemistry achievements;4 building up students' self-confidence in learning chemistry;5 enhancing students' interest in learning chemistry.In addition,this study compared the teaching effectiveness of the problem teaching method for various types of knowledge.The results show that the problem teaching method is more effective in basic concepts of chemistry and inorganic chemistry,but there were no significant differences in the results of the organic chemistry which is relatively unfamiliar to students between the experimental class and uncontrolled class.In summary,this paper sorts out the relevant theories and researches of the problem teaching method,and puts forward the implementation process of the problem teaching method based on the characteristics of Yunnan nationalities high school.It analyzes the effect of the problem teaching method in Yunnan nationalities high school,compares different teaching effects of the problem teaching method on different types of knowledge,and investigates the recognition and evaluation of students for problem teaching method,which provides a reference for the application of problem teaching method in Yunnan nationalities high school.
