Research On Concept About The Atomic Structure Of The Former High School Students

Before the concept is not consistent with the scientific concept views andunderstanding. Students in the learning of new knowledge, always trying to contacttheir original understanding, the understanding is more simple, not comprehensive,but the students think "OK","reasonable" point of view, they are difficult to give upor change your point of view. Therefore, the students’ understanding of conceptsbefore, understand the way of concept formation, analysis of the impact of preconcept of science concept learning is the urgent need to solve the problems in theteaching of the concept.This study takes constructivism theory as a guide, drawing on related researchresults, research concepts before the first grade students in the presence of highatomic structure of this core concept learning; on this basis, the answer isrepresentative of the students interviewed, analyzes the ways students before theformation of the concept of atomic structure. Study found that high school studentsheld before the concept of a lot of the atomic structure of these concepts before,except with the concept of common, because the students to understand the influencerule and the characteristic of chemistry, misleading the reasons mainly from theteachers, teaching materials, knowledge negative migration, affect the existingknowledge and life experience.Through the research, the author puts forward suggestions on the teachers’teaching and textbook compiling. Teachers should know the importance of theconcept in the pre teaching, in teaching standard terminology, appropriate analogy andreasonable for example, put an end to arouse students’ preconceptions. Write teachingmaterial process as much as possible to avoid an objective reality, students’understanding of inappropriate; based on the students before the concept, the probleminto the type to get a new concept; cognitive bridge built by students, closely relatedto establish the student life experience has been.In the practice research process,carries on the investigation, analysis of the former concept questionnaire of highschool formed in the aspects of the atomic structure. Then the representative of the answers in the questionnaire interview students, ways of forming analysis concept inhigh school students in the aspects of the atomic structure, put forward to promote theformer concept teaching strategy.Hope that this study can improve the chemical concept teaching efficiency andenhance teachers and provide the reference for the students’ understanding of theconcept of forming process.
