A Study On Formation Strategies Of High School Students' View Of Chemical Elements

Under the background of the new curriculum standard reform,the focus of this chemistry curriculum reform is to improve students' scientific literacy as the main purpose,pay more attention to the relationship between subject knowledge and social science,how to help students construct subject core literacy has become a hot topic in recent years.The view of chemical elements plays a leading role in the overall situation in the basic concept of chemistry,and has the value of domination and lasting transfer.It is of great practical significance to cultivate students' view of chemical elements to form chemical thinking methods.The author has been analyzed the basic connotation,constituent elements and the process of forming chemical element view,and has been constructed the chemical element view from three angles: knowledge of elemental compounds,teaching method and subject core accomplishment.The author has been studied and investigated the present situation of high school students' view of elements,and has been understood the development level of high school students' view of chemical elements and the teaching method of teachers' view of elements in actual teaching.Finally,the six teaching strategies of cultivating students' view of chemical elements was as follows.Such as:giving full play to the guiding role of core concepts in the study of elemental compounds;creating real problem situations in connection with the reality of production and life;analyzing students' learning situation and using concept map to construct element view;analyzing the logical system of teaching materials and cultivating students' understanding of chemistry and so on.The innovation of the thesis was to explore the forming process of element view from three angles: knowledge of element compounds,teaching method and subject accomplishment,and combined the questionnaire survey with the teacher's visit The result of the discussion explored the teaching strategies of constructing the view of elements.The construction of element view will be a long-term process,which requires teachers to fully excavate the corresponding core accomplishment behind each knowledge module in the teaching process,formulate the teaching goal based on coreaccomplishment,design the effective problem that can permeate the subject accomplishment,reach the teaching goal through the problem solving and the learning of element compound knowledge,and complete the construction of chemical element view.
