The Concept Of Prior Learning Of Physics Concepts And Transformation Strategy

Physical concept is the basic physics knowledge, an important part of students learning physics concepts is the physical basis of learning and key concepts of the master and the students will directly affect the level of understanding of other physical knowledge. When students learn physics, some students only mechanical memory of the knowledge taught by teachers do not know the physical methods of learning, when their existing concepts and scientific concepts learned in the contradiction, but keep in mind the concept of the study, figure out the reasons for conflict between the two, and only a small part of the students know the ins and outs of some physical knowledge, have some physical ways and means of learning, can clearly understand the contradiction between the two can be a good solution; traditional physics the concept of teaching, teachers will always intentionally or unintentionally, the minds of students as a "white board", by spoon-feeding teaching method of physical concepts to the students to the neglect of the active construction of student learning process, while ignoring the students already before the concept; the so-called first concept is the concept of students in learning science, before that they have formed a number of things or the views and opinions of certain phenomena. Some of the students before the concepts within a certain range is consistent with the scientific concepts, but some is also inconsistent with the scientific concepts, so the learning and mastery of scientific concepts can not be ignored role. Therefore, the education process must be based on the students before the concepts of generation and nurture it as a scientific concept of "growth point."This paper briefly introduces the concept of the importance of learning and the meaning of the former concepts are outlined on the previous day, also known as the concept of concepts, misconceptions, like heterogeneous want to wait, has not been specifically refers to teaching people in their daily lives gradually accumulated to form the concept. Then, at home and abroad about the concept of physical research before a brief introduction, and then in reference to the relevant literature and related research results, based on a combination of questionnaire and interview form, the concept of high school physics problems discussed before, analysis of some important concepts in physics the concept by the impact of the former reveals the causes of these former concepts and their characteristics, and further analysis of the concept of prior learning of physics concepts, and concept learning problems and so on. Finally, reference, according to the survey, presented the concept to the scientific concept of the physical transformation of the former strategy:concept map strategies, metacognitive training strategies, these strategies to guide the teaching and learning physics concepts, so that students learn more physics directional, so that more targeted teachers as much as possible before the use of the concept of positive transfer, avoid and eliminate the negative migration.Results of this study show that:(1) before the concept is real. (2) before the root causes of the concept from a wide range. (3) the physical characteristics of the concept before the concept of learning have a major impact. (4) to achieve before the concept into the strategies and approaches. Nepal is mainly based on the concept of assimilation theory Aosu and meta-cognitive theory, the concept of student learning through the internal mechanism and the analysis of problems and adopt effective strategies combine a variety of ways of thinking provoked the conflict between old and new students, so that Students to generate cognitive conflict, and the use or change their concepts before the final construction of new knowledge and the formation of scientific concepts.
