Analysis Of High School Physics Textbooks Based On The Core Literacy Of Physics

The competition of science and technology around the world is becoming increasingly fierce.The development of science and technology originates from talents,and the medium of talents is education.At present,the world pays great attention to education,and the educational experts have highly recognized the concept of lifelong education and constructivist learning theory.In order to improve the survival and development of students,it is advocated to improve the core quality of students in the process of education and teaching.This article refers to the newly issued "General High School Physics Curriculum Standards" in 2017,and selects the compulsory part of the high school physics textbook edicted by People's Education Press as the research object.Based on the analysis of the existing researches on the physical core literacy,the concept of each dimension element of the physical core literacy theory framework is defined operability,and it is used as a tool for the statistical analysis of core literacy in the textbook.Taking the section as the unit,the frequency and presentation mode of the physical core literacy elements in the compulsory part of the textbook are counted,and the following conclusions are drawn:(1)The model construction elements,scientific reasoning elements,scientific argument elements,and scientific essential elements of physical core literacy appear more frequently in the textbooks,and the content is better,reflecting the scientific knowledge and scientific methods in the process of textbook writing.(2)In the physical concept dimension of physical core literacy,the proportion of movement view elements,interaction view elements and energy view elements appearing in the textbooks is at a medium level;the problem elements,evidence elements and explanatory elements in the scientific inquiry dimension appear the frequency is at a lower-middle level;the STSE elements and scientific attitude elements of the scientific attitude and responsibility dimension appear at a low level in the textbook.(3)The time and space view elements of physical core literacy,the elements of communication,the elements of questioning innovation,and the elements of social responsibility are seriously insufficient in the textbooks.In response to the research results,the following implementation suggestions are proposed for the improvement of the preparation of new textbooks:(1)Increase the group cooperation and communication links in the physics experiment of teaching materials,and cultivate direct experience;In the assessment of communication,understand and consolidate physics knowledge,cultivate skepticism,critical spirit;(2)It is recommended to add the history of physics science and humanities knowledge in the questions and exercises.For example,the knowledge of physical scientists and other scientific knowledge as a group work,use the researcher's love of physics and the dedication of physics to cultivate students andand cultivate social responsibility with the relationship between physics and social civilization;time and space content can also be presented in the history of science and humanities.
