A Case Study Of The Different Conceptions Of Mechanical Concepts Based On FCI

Education and rejuvenating the country have become the consensus of the whole world,and talents are the foundation of the nation in the world today. Each country attaches great importance to basic scientific research, and as a scientific discipline, physics plays an indispensable role. Whether it is the frontier research scholars in Institutions of higher learning, or even in preschool education in the elementary education for students' scientific literacy training, the state has invested lots of manpower, material and financial resources, the authorities visible degree of importance for physical education. However, scientific research shows that the traditional education is to make students' ignorance of the state before formal learning, and that it is wrong for teachers to transfer the knowledge of human life to the students. Students are dynamic subjects, not completely ignorant of what they are about to learn. But more physics is closely connected with life,physical phenomenon is derived from the practice of life, therefore, in life, students have some physical phenomena have their own subjective judgment, although the need to go through the formal study of understanding of dragons and fishes jumbled together, and corrected, but education can not be underestimated,denied the subjective understanding of the students, and should use force to reverse the students' mistakes. These misconceptions, which exist before formal learning, are called"different ideas" in the minds of students.For the investigation of alternative conceptions in the minds of students,this study through literature review, understanding of the previous research results of this paper, the proposed the term alternative conception, and confusing terms associated with it,and discriminates the related terms, and the extract from specific concepts using the alternative conception the study of the. In the research phase of concrete,combined with the practice of the actual situation of the school, all students select two parallel classes as the research object,using the concept of mechanical test scale general international (Force Concept Inventory) or FCI, through the analysis on the data, finishing the objectively existing student alternative conceptions about the relationship between force and motion motion in the related concepts,and being in the understanding of students for the force and movement related concepts research students in the exchange, in which students have characteristics summary and alternative conception alternative frameworks of the crux of the problem, causes for the above alternative conception, to reverse the students'alternative framework in mind its own modest contribution.
