The Research Of Organic Chemistry Effective Teaching Strategy Based On Student's Learning Difficulties And Analysis Of Test Questions

Organic chemistry is an important part of chemistries in senior high school,which can reflect thinking method of chemistry better.Additionally,it occupies an important position in the National College Entrance Examination(NCEE)with its difficult and key features during chemistry teaching at senior high school,and the largest number of students are willing to choose this model in three elective models in the examination,while the students have difficulties in “method transformation” from inorganic chemistry to organic chemistry.Thus,it has great significance of studying on effective teaching strategies of organic chemistry.In this study,the author firstly collected relevant literatures about organic chemistry teaching at senior high school and found out deficiencies of existing literatures through analysis so as to determine research direction of organic chemistry.Then,the author launched program from two aspects: the first step is to analyze learning difficulties of students.Open questionnaires are used to investigate difficulties of students at senior 2 and senior 3 in organic chemistry learning.Then the author sorted out the main problems of students while facing with organic chemistry learning and found out original reasons through these questionnaires;the second step is to analyze the organic chemistry part of NCEE in recent 5 years from 2012 to 2016.Later,statistical analysis is used on test points and frequency in organic chemistry parts of NCEE and the reasons for losing points.Gradually,the author provided theory support and strategies in the aspect of organic chemistry teaching including knowledge network construction strategy,and organic model building strategy(spatial structure model of organics,organic inference model,organic synthesis model)through combination investigation about learning difficulties and test paper analysis of organic chemistry so as to promote learning transformation,on the basis of learning theory on information processing,learning theory on learning transformation,and learning theory on cognition.Finally,it is used for breaking through difficult points in teaching of organic chemistry and offer reference for frontline teachers.
