The Sorting And Analysis Of Fuzzy Restricted Words And Its Teaching Strategies In Senior High School Biology Textbooks

Fuzziness is the essential attribute of human language.In order to describe the biological knowledge scientifically and accurately,there are some inevitably fuzzy restricted words in the biology textbooks of senior high school,such as: The nucleus is the main place for storing genetic information;DNA is the genetic material of most organisms,and so on.Some of fuzzy restricted words are included in the test and make some students confused.Textbooks are almost the tools that teachers and students need to use in each class,it is the carrier of knowledge and the important basis for teachers to pass on knowledge.So it is necessary to study the fuzzy restricted words in senior high school biology textbooks.The author consulted literature of Fuzziness and vague language,defined the fuzzy restricted words in the senior high school biology textbook which published by Jiangsu Education,and analyzed the objectivity of fuzzy restricted words in textbooks.By reading the "biology curriculum standards for senior high schools" and other relevant examination instructions,combining the biological test questions and academic level test questions of Jiangsu college entrance examination in recent five years,and sorting out the typical fuzzy restricted words in five textbooks which Compulsory one,Compulsory two,Compulsory three,Elective one and Elective three.In order to test the typicality and reliability of the fuzzy restricted words,the author makes a questionnaire survey on some senior high school biology teachers and some senior two and three school students in some schools.Over investigation results it can be seen that the fuzzy restricted words that writer comb out is typical and reliable.Questionnaires were also found through teacher and student surveys,there are some teachers and students of teaching materials appeared in the fuzzy restricted words is low degree of concern,most of the teachers on the teaching method of fuzzy restricted words in the textbooks of the limitations of designated keywords and in the case citedcounterexample two ways.The author analyzed the fuzzy restricted words in Compulsory one.Around the content of fuzzy restricted words teaching given suggestions,the author put forward six kinds of teaching strategies,including future interest strategy,in-depth exploration strategy and special strategy,appropriate counterexample development strategy,key words strategy,contrastive induction strategy,for the majority of teachers in senior high school biology reference.The purpose of the subject research is not to establish relevant theories and to sum up the relevant laws,but to sort out and solve some of the details of the compulsory teaching materials of Jiangsu high school biology textbooks.
