Optimizing The Physical Law Teaching In Junior Middle School And Improving Students’ Scientific Literacy

In traditional middle school physics law teaching,teachers mainly pay attention to the way how to impart regular knowledge to students.Teacher always train students in the knowledge of relevant laws.Students’ interest and their scientific literacy are disregarded.This study is guided by the teaching idea of modern physics law.It studies the optimization scheme of physics law teaching in junior high school in detail.And put the scheme into practice.Finally,it has get a good teaching efficiency.This thesis summarizes the theories,characteristics,methods and strategies of physics law teaching at home and abroad.And it analyzes the concept,characteristics and requirements of physics law teaching in junior high school.Also the thesis analyzes the theories of cultivating and improving students’ scientific literacy.This thesis puts forward a scheme on how to optimize the law teaching.And it raises the clear question and make students form carry out the scientific thought.Students can do the scientific experiments and scientific reasoning.and also they can grasp the essence and relation of physical phenomena.Finally,the students can understand and master the laws of physics accurately.Meanwhile,they can apply the knowledge of physical law.This thesis carefully designed three teaching cases.And put these cases into practice.Case one,the teaching case of "rectilinear propagation".This case uses a series of beautiful light pictures and it contains some interesting little experiments.This case can arouse students’ enthusiasm.And students chat and discuss with each other in study.It can give students a feeling of beauty,allow them to feel the charm of physics and improve students’ scientific literacy.And this teaching case achieves a good teaching results.Case two,"plane mirror imaging".The case uses magic to introduce the teaching situation.It can build a series of mysterious and interesting practical activities for students.The case can guide students to understand the principle of plane mirror imaging and the application of plane mirror imaging in life.Case three,"the relationship between fluid pressure and flow velocity." The case let students do the little game of make a paper airplane,and take advantage of the common characteristics of birds and aircraft.It can introduce the airplane lift mode.Through a series of interesting experiments,the students are playing in middle school.Finally,students can learn the relationship between the fluid pressure and the flow velocity.Also,they could combined with the typical cases of life and production.Students are able to apply their knowledge.Their scientific literacy and the their physical law knowledge can achieve synchronous development.The case achieves a good teaching results.The innovation of this thesis is that it established a new optimization scheme of physics law teaching in junior high school.The scheme combines the teaching content with the junior high school students’ cognitive level and psychological characteristics.The scheme attracts students’ interest through carefully designed experiments.And it also improves students’ scientific literacy.The scheme is scientific and reasonable.After testing,the scheme achieves a good teaching results.
