Practice Research On The Experimental Teaching Of Junior High School Physics "Light Phenomenon" Unit Based On Scientific Practice

"Scientific practice" is the inheritance and development of "scientific inquiry",and since the term "scientific practice" entered the field of science education,it has caused new changes in international science education.With the promulgation of the new curriculum standards for compulsory education,China has paid more and more attention to the cultivation of students’ core competencies in physics and students’ practice.Therefore,this study has a role in "Does unit experimental teaching based on science practice promote the development of physics core literacy of junior high school students?" "Conduct research,which is divided into two parts: theoretical discussion and practical research:Theoretical discussion: Through reading a large number of literature on scientific practice and unit teaching research,we will discuss and summarize how to design pre-and after-class physics experiments based on scientific practice and the key links of physics experiment teaching in class.Practical research part: The author selected two natural classes in the internship school for research,and practiced the overall planning and lesson teaching design of the "Light Phenomenon" unit experiment based on scientific practice in the experimental class.After the teaching practice,the students were assessed through the unit test of students’ core physics literacy and students’ hands-on practical work,and the following conclusions were reached:Unit experimental teaching based on scientific practice cannot significantly improve students’ core literacy in physics in a short period of time,but it has a certain role in promoting the development of junior high school students’ scientific inquiry literacy,and at the same time has a positive impact on students’ academic performance,and helps to improve students’ scientific practice ability.
