Evaluation And Research On The Formation Of Refraction Law Of Senior High School Students In The Context Of Optical Development History

As an important subject of natural science,basic physics education carries the important task of improving students’ concept formation level and core literacy.In the context of optical development history,based on the concept formation level and the development context of refraction law,the test paper is compiled to test the concept formation level,core literacy and influencing factors of refraction law concept formation of senior three students.Based on the analysis and synthesis of relevant literature,this paper first determines the dimension of concept formation according to the theory of concept formation at home and abroad,divides the concept formation level into 3 levels and 9 levels,and designs the concept formation level scale according to the concept formation level.Then it explores the historical context of the refraction law,presents the historical context of scientists exploring the refraction law and its related concepts,and obtains a two-way detailed list of knowledge topics and concept formation level according to the development history materials of the refraction law.Referring to the twoway detailed list,the concept of refraction law is designed to form a test paper,which is distributed to experts and front-line teachers for correction.Combined with expert suggestions and the characteristics of senior high school students,the concept of refraction law is revised to form a test paper,and the consistency of the revised concept formation level and content theme of refraction law is analyzed to finally form a concept of refraction law and form a test paper.Then,the practical research on the formation of the test volume of the concept of refraction law is carried out,and the quantitative data obtained from the practical research are descriptive statistical analyzed with SPSS25 and excel.Finally,according to the quantitative data of the practical research,the data are analyzed from three aspects: the level of the formation process of the concept of refraction law,the core literacy and the influencing factors affecting the formation of the concept of refraction law.The analysis results are as follows:1.Conclusion of the formation of the concept of refraction law:(1)Analysis on concept formation of refraction law:Description of the concept formation level of refraction law in each class: the concept formation level of refraction law in Class C1 is the highest,with 63 points,accounting for 92.6%of the total score(68 points),and the concept formation level of refraction law in class C4 is the lowest,with 7.5 points,accounting for 11.0% of the total score.Description of the proportion of achievement of each level in the concept formation level of refraction law: the proportion of achievement of each level in the concept formation level of refraction law falls in a ladder shape.Each class has the highest proportion of achievement of knowing level,slightly lower proportion of achievement of understanding level and the lowest proportion of achievement of being able to do level.(2)Comparative analysis of various levels of the formation of the concept of refraction law:From the average of the total standard scores,the standard scores of Class C1 and class C2 are positive,indicating that the formation level of refraction law of Class C1 and class C2 is above the average level,and the average score of Class C1 is greater than Class 2,indicating that the level of Class C1 is higher than that of class C2.From the average value of standard scores at all levels,the level of C1 class at all levels of the formation of the concept of refraction law is above the average level and higher than that of other classes;The formation level of refraction law in C4 class is below the average level,and the level is the lowest on the level of knowledge.2 conclusion of core literacy: Class C1 has the highest level of core literacy and class C4 has the lowest level of core literacy.3 conclusion of influencing factors on the concept formation level of refraction law: the influencing factors on the concept formation of refraction law include wrong modeling,concept confusion,concept ambiguity,scientific attitude cognition error and operation error.At the level of knowledge,the most influential factor is concept ambiguity;At the level of understanding and being able to do,the most influential factor is conceptual confusion.The conclusion of this study has some enlightenment on the research of concept formation level,the influencing factors of concept formation and the practice of Physics Teaching in middle school.
