Application And Research Of Paradigm Teaching In High School Chemistry Theory Knowledge

In the era of rapid increase of the total amount of knowledge,heavy academic work makes students bear great pressure,and the characteristics of diversified and scattered chemistry subjects also bring great burden to students' study.The concept of "reducing the burden on students" has become more and more popular.In 1951,the historian Hermann Heimpel proposed the idea of paradigm teaching,which was originally intended to solve the problems in education of federal Germany,such as the bloated teaching contents of various subjects,the increased academic burden of students and the decline of teaching quality.Since the conception was put forward,scholars have carried out theoretical and practical research,and found that the paradigm teaching method has an effect on students' mastery of knowledge and the cultivation of the core accomplishment of chemistry.On the analysis of the domestic and foreign research on paradigm course,on the basis of related theory as the support,based on the ordinary high school chemistry curriculum standards(2017 edition)",the construction of high school chemistry theoretical knowledge paradigm teaching research model and the implementation of high school chemistry theoretical knowledge paradigm teaching strategy,the questionnaire before the conclusion on the basis of practice,paradigm teaching method of the implementation of the requirements,carries on the teaching design and implementation.In the fourth stage of paradigm teaching,students' application of knowledge is emphasized,and students are required to pay attention to the social issues related to chemistry,which is conducive to the cultivation of "scientific spirit and social responsibility" in the core accomplishment of chemistry.Two classes in sanmenxia No.1 senior high school are selected as the research objects,and the two classes are parallel classes.In accordance with the established research model for practical research,in the experimental class teaching,teaching practice after the research object questionnaire analysis,focusing on the students' grasp of basic knowledge and the four stages of paradigm teaching.The research shows that :(1)The paradigm teaching method is in line with the learning characteristics of high school students,which makes them realize the fun of learning chemistry and effectively improve their learning initiative.(2)By implementing the paradigm teaching,students can master the theoretical knowledge and transfer the rules to another kind of things,which reduces thedifficulty of learning,reduces the pressure of learning,and enhances the confidence of learning chemistry.(3)Students can apply the knowledge they have mastered to solve practical problems in life,feel the wide application of chemical knowledge,and cultivate the core accomplishment of chemistry.On the whole,the paradigm teaching accords with the student development,enables the student to acquire the knowledge efficiently,the development ability,is worth to carry on the attempt and the research.
