Theory Study And Practice In View Of Project Based-learning In The Chemistry Teaching Of Middle School

It is a mode of a kind of probing into study which the middle and primary schools of U.S.A. adopt extensively at present " Project- based learning ". Its theoretical foundation is pragmatism education theory, Bruner's plural intellectual theory of studying the theory and Gardiner of discovery of building the doctrine of constructing and studying theory, Dewey. This text is from analyzing the chemical teaching situation investigation and chemistry of some key middle schools in Jiangxi Province study the situation investigation and set out, is it use" Project- based learning " the mode go on teaching among the chemical teaching in middle school to propose, in order to change the current situation of the chemical teaching of middle school with single mode at present.Learn the mode to being based on project, from this text from " project" , " model of teaching", the circles of odd concepts is it take place to make "project-based learning", etc., to is it analyze on the basis of theoretical foundation that project study , carry on the discussion to operation course of mode this systematically to go on, students' role carries on the localization to the teacher in the procedure of operating. Should teach mode apply practice to, high second grade make up " comprehensive utilization of used battery ", " fountain experiment study " , "water" in Rui Jin First Middle School -Source thematic speech of the life ", "the lead poisoning prevents consciousness from being investigated ", "the garbage disposal of the city is investigated ", " analyze by red rock soil sour alkali degree " , " specialist lecture of acid rain" , " the black-and-white photograph is made " , " the chemical picture library of middle school is made" nine projects study the group. Study in group's teaching practice because of the project in nine, especially to " lead poisoning prevent from consciousness investigate" and " black-and-white photograph make " two teaching cases go on evaluation and analysis this text, draw based on project to study mode have effectiveness strong, educational teaching result remarkable conclusion.Through to " based on project to study" mode theory make analysis and discussion this text, use to middle school first line " Project- based learning " mode carry on case that teaching practice make analysis and appraise, think that uses this mode to carry on teaching, is favorable to the realization of the new course goal, can combine the study of the knowledge skill together in the cultivation that students practiced ability effectively; Use this mode to carry on teaching, help to change our country's already existing single appraisal system; Use this mode to carry on teaching, help to train students' Science Explorations spirit and innovation ability.
