The Research About The Junior High School Before The Simple Circuit Concept Transformation

Scientific concept for middle school physics are very important,it will effect physics study for a long time.Studies have shown that students have many preconceptions before current study,and students have the concept after current study.For the physics concepts before physics education,the author proposes some concept transformation strategy:get to know the concepts of students;initiate the concept of cognitive conflict of students;encourage students to recombine cognitive structure;adoption analogy teaching method.In teaching design,when cognitions are in conflict,it need to establish a new model.That can adjust and change their original structure of cognition.At last,the author carried on a practical research,the effect on the strategy of preconceptions was tested.The author run tests to evaluate students between the experimental class and the control class.The results conclude that the achievement of the students in the control class is more significant improved that the experimental class.The result indicates that the strategy can help students to change the simple circuit concept before physics education.
