An Analysis Of The Constructions Of The Lower-Years' Primary School Scientific Concepts According To The Error Preconception

On the stage of the primary school compulsory education,science teaching takes the important responsibility of the scientific enlightenment,and in which scientific concepts make great effects.While studying science,it is helpful for students to have a construction of the scientific concepts which may make them understand science much more correctly and comprehensively.But the lower-years' are not knowing nothing about the scientific concepts,but having error preconceptions.And error preconceptions may have a great effect while they're studying science and having a correct concept conception.If teaching based on the error preconception,it is not only requests teachers to pay more attention on students' studies,but also needs to give advices in time,so that it can achieve the aim of rebuilding scientific concepts and making scientific enlightenment come true.I take a research on the error preconceptions and try to find the causes for this association through the methods of the literature research,questionnaire and interviewing.Then I find the lower years' students have error preconceptions on the concepts of “Dissolution”,”Magnet”,”Moon phase” and so on through a random selection of the teachers and students in the city of L.And the reasons of having error preconceptions are because of the following: Daily experience comes first,approximate concepts are vague and confusing,and scientific method is not operating properly,negative transfer of scientific concepts and so on.This paper is aiming to solve the bad effects on the scientific error preconceptions to primary school science teaching by analyzing those reasons mentioned.And this paper may have a solution on these issues through these four aspects which are put forward a detection of pre-concept and have a rational plan on the conceptual construction;intuitively differentiating pre-concept and correctly standardizing concept construction;pay more attention to the import methods and construct concept efficiently and correctly;strengthen thought-guidance and promote the independent construction of concepts.
