The Survey And Practical Research Of Physics Class Preview In High School

Scaffolding is a new teaching model in constructivist theory under "recent developments" guidance raised, compared with traditional classroom, it pay more attention to the dominant position of students and active construction of knowledge process.This paper expand this study,the "cradle" teaching model used in teaching high school physics research,analytical applications in high school physics teaching method of "cradle" teaching model and to investigate the validity of the model, I hope to give the majority of high school physics teachers reference.Firstly, through literature, the paper combined with the theoretical basis of relevant research results on the subject and conducted inspection and study to build a research content of this paper.Secondly,through high school physics compulsory "law of conservation of mechanical energy" chapter of practical research, the front side of the students found their zone of proximal development, and to guide teaching, set up the stand in a recent development in the region to start teaching. Results of the questionnaire survey of students showed that conservation of mechanical energy for the content of this section,students in junior secondary basis of existing knowledge, it is possible to improve a degree of development and through rehearsal and life experience, while accepting some knowledge and understanding the use of barriers still exist. Therefore, when the holder to carry out teachingstyle, pay attention to the recent developments in the area of student conduct Scaffolding and grasp the knowledge construction process and methods, so that students are taught knowledge and skills learning unconsciously, becomes passive acceptance of knowledge to active construction of knowledge, skills upgrading and completion of teaching objectives in a relaxed atmosphere, the full development of the body and mind. In teaching, based on the zone of proximal development is recommended to carry out teaching different teaching contents cleverly selected bracket become passive to active, the hands of students returned to the classroom.Then, on the "law of conservation of mechanical energy" chapter in accordance with the theoretical scaffolding teaching mode requires scaffolding instruction design and carry out teaching of students,followed by the integration of the results of its study to verify the feasibility and effectiveness.Finally, we get the following conclusions:Scaffolding Instruction in teaching can help teachers found that students in different stages of the learning state, the level of real and potential level of development knowledge to master, making instructional design, to fully take into account the student’s zone of proximal development in the zone of proximal development and teaching were set up within the stent.For students, to realize that learning should be a positive initiative of the construction process, should think more and more hands and mouth,and to be good at communication and cooperation; secondly to have their own clear learning objectives, level of development of each student’s reality not quite the same, each person’s good points and interests are not the same, so for myself, set appropriate learning objectives and efforts as much as possible to improve their own weakness while continuing to enhance the advantages of the project.
