Research Into The Education Of Scientific Approach About Idealized Model In The Teaching Of Mechanics In A High School

The method of idealized model is an important scientific method, strictly speaking, the object of study for the most part in physics in middle school and even college is the idealized model. At the same time the method of idealized model has applied to every phase of physics study in high school, so it is an important scientific method to analyze and solve the problem.Based on the constructivism and migration theory, according to the book of Senior High School Physics Curriculum Standard (Experiment) and the new high school physics course materials (Physics1and Physics2), combined with the research findings of the education of significant scientific methods and the role in physics research and physics teaching, this paper discourse from three aspects in the construction process of the idealized model, the objectives and principles in the idealized model teaching. Then on the basis design a teaching case and analyze that.Based on the Senior High School Physics Curriculum Standard (Experiment),the new materials of high school physics course,curriculum resources, the material about history of physics and the characteristics of psychology and age, this paper analysis the education target levels of scientific method from the perspective of the law of students’ cognitive development, and finally come to four levels about teaching of the idealized model. Firstly, understand the characteristics of an idealized model in the study of physics; Secondly, enable students to experience the approach of idealized model; Thirdly, make sure students can try to use this method to study physical problems on other occasions; Last, enable students to understand the significances in solving physics problems and explore the laws of natural world about the idealized model.Based on the characteristics of the physical scientific method and cognitive rules of students, we propose the basic principles of education must be followed to carry out the physical sciences, that is: with the combination of the principles of the physics teaching, the principle of following in proper sequence, the principle of combining students main initiative with teachers guide, he principles of demonstration and practice, the principle of significant scientific methods of education. This paper emphasizes: we must clear the specific objectives of teaching about the idealized model first in the teaching of idealized model, and teach in accordance with the principles of education of scientific methods. As a teacher, we must disinter the feature and logical meanings of idealized model, organize teaching based on the method, and help students to acquire knowledge through scientific method.Science method education and knowledge education should be parallel, and only if we reify the goals of the educational about the scientific approach, it is conducive to the actual teaching of evidence-based and implementation in-depth. In the teaching, we should contrapose the characteristics of specific scientific methods, expand on the meanings of scientific method, and get knowledge from using the scientific method. Only if Students through this process, will be buried in the mind the seeds of method, took root and grew.
