The Research And Application Of Alternative Framwork And Conception Change

In the education theory we called the thinking and understanding are alternative framework. Which deviate from science conception and science phenomenon essence and caused just by the perceptual cognizance.In the physics education we called the alternative framework are mostly refers to the inherent in wrong views and opinions formed before studying the physics conception,just bu oneself’s life esperence and the former study.Students in learning physical knowledge is not an empty head into the classroom, like a piece of white paper what the teacher teach students knowledge accept what scientific knowledge. But through a variety of ways, some of the concepts and phenomena have some perceptual alternative conception. Because of the existence of alternative conceptions and learning physics has a negative effect, using only the traditional way of teaching in physics teaching is far from the ideal teaching effect and achieved good results. So for some physical knowledge and concept of students alternative conceptions, teachers must adopt some corresponding teaching strategies to guide students to realize the concept of change in teaching, so as to let the students understand the physical phenomena and the meaning of knowledge learned from nature, really understand the connotation of some physical phenomenon, stimulate learning enthusiasm and to physics learning interest.This paper through on-the-spot investigation, literature analysis, questionnaire research on alternative conception existence reasons and some characteristics of the. According to the characteristics and the reasons put forward the conceptual change theory, and summarizes some ways and means of conceptual change. At the same time puts forward some concept transformation of DO NN three step five step teaching, teaching OF four stage teaching and 5E teaching mode. In order to further study the feasibility of alternative conceptions in the actual operation, select Shandong Mengyin daigu, fourth grade students as the research object, research and practice of teaching related to this section of force and motion. And through the research and practice of the experimental class and the control class, confirmed the feasibility of conceptual change theory. Practice has proved that the teacher applied some conceptual change strategies in the classroom, students can be more active to participate in the classroom teaching, thus changing the classroom atmosphere, enhance the enthusiasm of students, improve physical performance. Enhance the student interest in learning physics.At the end of the study at home and abroad alternative conception research results, starting from the perspective of alternative conception, in order to investigate the features of different ideas and their mind alternative conception in physics in middle school from the start, put forward some cognitive conflict, using the experiment inquiry teaching, change the concept of cooperation learning strategy.
