The Research On Applying Scaffolding Instruction To Electromagnetism Teaching In Junior Physics

Science education in the process of improving scientific literacy plays a decisive role,physical education occupies an important place in science education and can help to promote scientific literacy.However,the physics of highly abstract,logical characteristics tend to students learning in trouble,and electromagnetism is the most difficult part in physics.Constructivism pointed out that students complete a higher level of learning task requiring a lower level of knowledge and ability levels as support.Abstract and logical ability of junior middle school students are still at an early stage,students construct their own knowledge system step by step with scaffolding's support in the learning process of electromagnetism.Based on the cognitive theory of constructivism,study on scaffolding instruction in the application of electromagnetic teaching in junior middle school,carried out the following work:Base on the theory of constructivism,recent development area,Ausubel' s learning,to define the conception of scaffolding instruction.According to the psychological characteristics and learning effects of the middle school students,scaffolding to be divided three classes include heuristic,experience and evaluation.The processes of scaffolding instruction are breaking down the learning tasks,determining the zone of proximate development and learning style,last,organize works.Based on the theory and practice of instructional scaffolding,feature,combined with the actual situation of physics teaching in junior middle school in Yunnan province,through a questionnaires surveys the teaching status for scaffolding instruction in junior high school physics teaching.The result shows that most teachers are not familiar with scaffolding instruction that cannot effectively be applied to teaching.To use scaffold effectively require teachers make study of scaffolding instruction about the types and the ways to set up.Based on the analysis of the questionnaire,Authors designed the three teaching cases include "Ohm's law","power" and "magnetic".In the process of designing,according to the reason of usingscaffolding instruction,The procedures of the instructional design,the theory and the difficulties in students learning to conduct analysis,reflection and summary.
