The Teaching Status Quo And Improvement Countermeasures Of High School Chemistry "element Cycle Law"

Periodic law of element of knowledge has a history of one hundred years,in the national curriculum standard is increasingly perfect today,periodic law of element as an important part of high school chemistry theoretical knowledge,the teaching requirements also more and more keep improving.For foreign periodic law of element teaching current situation of literature retrieval,found that study abroad teaching resources are scarce,therefore,the content of the periodic law of element in the teaching materials from abroad and the country's scientific demand side to analyze the teaching status quo of foreign periodic trends.Comprehensive literature retrieval teaching research,put forward on the teaching of periodic law of element innovative teaching ideas.Research teaching concept as the core,based on the research of the classroom teaching activity,student's questionnaire research and different stages of teachers' interviews,induces periodic law of element present situation of teaching are: involved in the scientific development of historical facts content is one-sided;students are difficult to digest the complex knowledge;teaching away from real life;scientific experiments to explore some less and as the main body is teachers.To solve the problems found during the survey,follow the stage of Piaget's cognitive development theory,implement the humanistic theory of ideas,innovative teaching design of periodic law of element.This research main design innovation of teaching content including: the student the process of collecting data and scientific development of historical facts about science development;design a comprehensive model;add elements in the application of life,the comprehensive implementation of Science technology society;Take the student as the main body of scientific experiments to explore.Combined with the result of the education expert comments,it is concluded that integrating the above teaching research results of element periodic law teaching design,can solve the problem of the above situation reflected,also reflected the modern teaching idea--comprehensive training students' chemistry subject core literacy.
