Content Analysis Of High School Physics Textbooks Based On Physical Core Literacy

The “Guiding Opinions on Promoting the Educational Reform of General High Schools in the New Era” issued by the State Council states that,by2022,the new curriculum and college entrance examination reforms for general high schools will be fully launched and new textbooks will be launched.The new textbook is oriented towards the implementation of the task of “ cultivating the young by foresting a lofty ideal”,which is a concrete manifestation of General High School Physics Curriculum Standards(2017 Edition)and an important carrier for the cultivation of Physical core literacy.This article selects the compulsory one of the first edition of the PEP in 2019.First,it develops a set of quantifiable standards for Physical core literacy.It uses the content analysis method to quantify their presentation in textbooks,and then uses the induction to summarize the embodiment of textbooks in the cultivation of Physical core literacy.The following conclusions are reached in the quantitative analysis:(1)On the whole,in the presentation of the four aspects of Physical core literacy,scientific thinking and scientific inquiry dominate;(2)Judging from the specific presentation of each element,the frequency of presentation of the three elements of model construction,scientific reasoning,and evidence is relatively high,and the frequency of the four elements of movement view,problem,interaction view,and scientific essence is at a medium level;(3)The frequency of interpretation,communication,and scientific attitude elements is relatively small.The five elements of matter view,questioning innovation,scientific argumentation,social responsibility,and energy view are the most lacking.The following conclusions are reached in the qualitative analysis:(1)The setting of chapters,the construction of concepts and laws are worth exploring,which is in line with students' cognition and conducive to the cultivation in physical concepts;(2)Orderly and systematic penetration of scientific thinking and scientific methods,and the column of "scientific methods" has been added;(3)Emphasize scientific inquiry.On the one hand,it attaches importance to the effectiveness of evidence in the construction of concepts and laws.On the other hand,it adjusts the structure and changes the writing of experimental inquiry courses to guide students to conduct scientific experiments.(4)Attaching importance to scientific attitude and responsibility education,emphasizing the combination of theory and practice,and highlighting STSE thought are obviously seen.
