Discussion On The Establishment Of Physics Key Competences Scale For Senior High School Students

With the new round of curriculum reform carried out by the national education authorities,the core quality of physics has become the focus of discussion and research in the field of education.Then another problem is put in front of educators:under the framework of the new curriculum reform,how to objectively evaluate students'core qualities of physics and effectively test our educational achievements.Obviously,a physics paper cannot meet this requirement.Therefore,it is necessary to study the measurement of physical core literacy.In this paper,questionnaire survey,interview,factor analysis,data analysis and other quantitative and qualitative research methods.Taking "new physics curriculum standard(core literacy edition)","yunnan academic level examination outline"and"scientific literacy questionnaire"as reference,combining with the teaching practice in senior high school,this paper sorts out and analyzes the three levels of core index framework that can reflect the core literacy of senior high school students in physics.Among them,there are 4 first-level indicators,20 second-level indicators and 128 third-level indicators.Then,relying on the three-level index framework and combining with the relevant theoretical knowledge of psychometrics,the specific items of the scale are compiled in the mechanics part.Specific items have been strictly screened,necessary preliminary and retest have been conducted,and the reliability test of statistics has been conducted.The scale developed in this paper has achieved high reliability and validity.Of course,the scale developed in this paper belongs to the educational measurement scale.In the actual operation,samples from different regions or different time periods are selected for measurement,and the results may be different.The compilation of educational measurement scale is a huge systematic project in itself.Without mature experience reference,the author was forced to make a meaningful attempt due to practical needs.The scale compiled is only the mechanical part,and users should update and improve it according to the actual situation before using it.
