Strategies Of Developing The Students' Expression Ability In High School Physics Examinations

In physics exams,what examinees lose easily is not pure certain physics knowledge,still have the answer in the exam the step is written not standard.The subjective questions,which account for 70% of the total score of physics,are composed of experimental questions,computational argumentation questions and optional questions,focusing on the backbone knowledge and discipline comprehensive ability of high school physics.It is a basic skill for the examinee to express the physics examination paper in written form.This is also restricting a part of the excellent students can not get full marks,high scores one of the factors,especially after the implementation of online marking,the specification of the problem solving and the cleanliness of the paper put forward higher requirements.At the same time,the ordinary high school physics curriculum standard(2017 edition)"with" core literacy "instead of" the ordinary high school physics curriculum standards(2011 edition)"in the"knowledge and skills,process and methods,emotional attitude values "three dimensional goal,and points out that: the physical discipline core literacy is mainly composed of" physics concepts and applications ","scientific thinking and innovation","scientific inquiry and communication","the scientific attitude and responsibility" four aspects of the elements.Compared with the old curriculum standards,the new curriculum standards emphasize more on students' communication ability in physics.In terms of the accomplishment of "scientific inquiry and communication",it is clearly pointed out that students should have the willingness and ability to cooperate and communicate,and can accurately express,evaluate and reflect the process and results of inquiry.And high school students in the process of learning physics,the main way of subject communication is the written expression of physics exercises.This topic by setting high school physics papers written specification standards,from the viewpoints of both teachers and students in ordinary high school physics teaching in the physics exam papers written specification strategy of cultivating the ability of expression,the researchers after a semester of personal teaching practice,observation and analysis of the class as a whole,the physical difference,and the physical writing is not standard of students' physical performance and proved from the physical ability training of papers written specification,is the core can improve the high school physical science literacy and improve students' physical performance.
