Research On The Teaching Strategies In The Construction Of Ion View In High School Students

One of the important purposes of chemistry education is to improve the chemistry core literacy and promote the development in comprehensive qualities of students to satisfy the requirement of society as the qualified citizens in the future.In the process of receiving chemical education,students will finally understand the chemical knowledge in deep level and form the basic chemistry concepts through the initial understanding of the specific knowledge and skills of chemistry and subsequently continuous consolidation and deepening of the knowledge.The article focuses on the research on the teaching strategies in the construction of ion view in high school students under the guidance of constructivist theory.The difficulties on the study of ion view encountered by the students in the high school where author was engaged in pedagogical practice were identified through the methods such as literature review,educational experiment,classroom observation,teacher-student interviews and statistical analysis.The teaching strategies for breaking through the difficulties to construct the ion view were put forward,including:(1)Improving cognitive structure of individual to promote the cultivation of ion view;(2)Constructing models to help students understand ion view;(3)Cultivating ion view through inquiry teaching;(4)Strengthening memory to consolidate ion view;(5)Arousing interest to induce the formation of ion view.Through a comparative study between the experimental class and the control class in the high school by exerting of above mention strategies,it was found that the implementation of the above strategies could promote the construction of the ion view of high school students.The students in the experimental class have greatly improved the effectiveness,the pertinence and the learning confidence.Additional,the exertion of the teaching strategies may improve the teaching level of the teachers.
