Investigation And Research On The Teaching Status Of The "Material Structure And Properties" Module Of High School Chemistry

The “material structure and nature” module is an important part of high school chemistry knowledge framework,and plays a fundamental role in high school chemistry learning.The knowledge of “material structure and nature” module is abstract and hard to understand,which makes teachers have many problems in the module teaching.Therefore,the implementation of “material structure and nature”teaching is taken as the research content,and some suggestions are put forward.In the first chapter,the paper summarized the research results of “material structure and nature” teaching of senior high school chemistry at home and abroad,especially the research results of textbook analysis,students' learning disabilities and learning difficulties,teaching strategies,etc.,and brought out the research problems,research methods and research ideas of the paper.In the second chapter,the paper briefly reviewed the two theories of teaching and learning process: learning motivation theory and constructivism theory;summarized the content of the “material structure and nature” module and the requirements of the new curriculum standard;and summarized the composition and content of the high school chemistry core literacy.The content of this chapter is the theoretical basis for the analysis of the survey data.In the third chapter,the paper explained the relevant questions of the questionnaire.Based on the analysis of the interview results,a questionnaire on the teaching implementation of “material structure and nature” module in senior high school chemistry was compiled.The questionnaire was distributed to the wechat group of senior high school chemistry teachers in each county and district of Tangshan City for investigation.Using statistical software SPSS22.0 the data reliability analysis was carried out,and the Klenbach coefficient ? is 0.911(> 0.9),which shows a good reliability and usefule value of educational measurement.In the fourth chapter,the paper analyzed the survey results,including the following aspects:(1)teachers' understanding of the new curriculum standard;(2)teachers' understanding of module opening;(3)teachers' understanding of textbooks;(4)teachers' understanding of teaching;(5)teachers' understanding of the influences of learning the module on students.In the fifth chapter,the paper summarizes the survey results and analysis,and puts forward constructive suggestions.The results show that:(1)the opening of the module of “material structure and nature” was in good condition.Most teachers thought that the difficulty of the module was moderate,which was helpful for the formation of scientific values;(2)most of the teachers had a good grasp of the new curriculum standard and the core quality of chemistry;(3)among the factors that affect teaching difficulties,most teachers thought that abstract knowledge and difficult-imagining spatial configuration of particles were the most difficult points.The paper puts forward three constructive suggestions:(1)schools should carry out teacher training activities in various forms to improve teachers' teaching ability;(2)teachers should control the teaching process in many aspects and adopt flexible and diverse teaching forms to improve teaching effect;(3)teachers should take active and appropriate ways to solve the various problems encountered in teaching according to the content characteristics of “material structure and nature” module.
