Based On The Inter-ethnic Comparative Study Of The Teaching Ability Of Dong And Lisu High School Students' Chemistry Lattice Ability

Based on field work,this paper mainly adopts the method of natural experiment and comparative method.This paper aims to quantitatively study the chemical lattice abilities of senior students of Dong ethnic group in Tongdao county and Lisu ethnic group in Gongshan county.Then,from the perspective of cognitive anthropology,this paper analyzes the qualitative differences and puts forward some suggestions on teaching students according to their aptitude.This paper consists of three parts:The first chapter,based on the existing schema theory,expounds the ability construction process of bottom lattice,position lattice and top lattice in the concept of schema inferior.On this basis,the knowledge structure of the five major sections of high school chemistry is analyzed,including the classification of substances,the structure of substances and the periodic table of elements,metal elements and their compounds,nonmetal elements and their compounds,and organic chemistry(isomers).The second chapter analyzes the knowledge structure of high school chemistry based on lattice ability and designs the questionnaire,describes the research object and process.According to the data and data of field work,the cognitive facts about chemical lattice ability of the two groups of senior high school students were compared and analyzed.It was found that the scores of dong students lattice base and lattice top were slightly higher than the scores of lisu students lattice base and lattice top,but the difference was not obvious.By comparing the position lattice abilities of dong students and lisu students,it is found that the score of lisu students position lattice abilities is obviously lower than that of dong students position lattice abilities.The third chapter,from the perspective of cognitive anthropology,analyzes the correlation between the difference of lattice ability between dong students and lisu students and the tendency of ethnic cultural character.Through the analysis,it is found that ethnic cultural character of dong students tend to be "weak mountain type" and ethnic cultural character of lisu students tend to be "weak water type".The "weak water type" of the lisu ethnic cultural character,the performance of the characteristics of the loose and not focused,makes the lisu students in the position lattice score is relatively low.Because of the need to focus on the position lattice,it is necessary to cultivate the lisu students’ compound thinking of knowledge structure,especially to strengthen the training of knowledge structure with the principle of "having and having only" and the strictness of the logical relationship between knowledge hierarchy.Moreover,it is suggested that teachers in minority areas cas grasp the "lattice ability"of different students to teach students according to their aptitude,so as to improve the chemical academic achievement of high school students in minority areas more effectively.
