Research On The Current Situation Of High School Students' Physical Model Construction Under The Background Of Core Literacy

The core quality of physics refers to the necessary ability and character that students should have to adapt to their own and social development needs after learning physics knowledge.As an important part of the core quality of physics,"model construction" promotes the formation of students' scientific thinking and the study of physics.So after the core literacy is put forward,which level of "model construction" of students has reached the new curriculum standard? This is a problem worthy of study.In this dissertation,we collected one physics question and 230 answer cards of the second comprehensive examination of senior three in a middle school in Baise City,Guangxi Zhuang Autonomous Region.According to the description of the level of physical model construction in the physical core literacy,and combined with the specific situation of each question,we formulated the evaluation standard of each level.According to the evaluation criteria,the collected answer sheets are evaluated and the model construction level of students is analyzed from the perspective of different physical models,gender and class.The results show that:(1)the degree of mastering the molecular structure model is higher than that of the celestial body motion model.Among all the structure models,the electric field structure model is the best,and the scoring rate of the system models at different levels is quite different.The model of similar horizontal throwing motion process,collision system and isochoric process meet the requirements of graduation qualification set by the new curriculum standard.(2)The average score rate of boys is higher than that of girls,but the score rate of boys in magnetic field structure model and electric field structure model is slightly lower than that of girls.The average score rate of each level of the key class is higher than that of the ordinary class,especially the score rate of level 4 is significantly different.(3)Students' migration ability is weak,so they can't use the model flexibly.Poor modeling awareness.(4)The teacher neglected the highest level and the lowest level of questions.(5)From the results of the evaluation,the evaluation criteria developed in this study can reflect the level of the students in this test,which has a certain degree of effectiveness and operability.This study provides a certain reference for us to evaluate the level of model construction of students in the future,and also provides a reference for the future research of model construction in physical core literacy.
