The Study Of Senior High School Students' Physics Modeling Competence And Cultivating Strategy

Today,in vigorous development of science and technology and increasingly competency,science education is more important,which is the key way of scientific literacy improvement and innovation ability development.How to effectively realize the educational function of science education.The consensus view in the field of international science education is that"learning science is learning how to modeling,and only know how to modeling can promote the development of students' scientific literacy and scientific concept".In many countries,scientific modeling competency has been considered as the main issue in the new science curriculum standard.In our country,the physics modeling competency is also included in the framework of the physics core literacy,as a key guiding ideology for revising new high school physics curriculum standard.Although the value of modeling competency in physics and even science education has been widely recognized,but the physics modeling competency elements which is the prerequisite for cultivating physics modeling competency is still not clear.At present,there is a lack of systematic and in-depth empirical research on this subject at home and abroad.The empirical research on physics modeling competency elements is just a problem that might has a large theoretical and practical significance in academic research,in national educational policies,in schools.Therefore,this thesis chooses to study the structure of physics modeling competence and the cultivating strategy of students'physics modeling competence from the perspective of disciplines of physics.The topic has theoretical and practical significance for the cultivation and development of students' physics core competence.This research carries out an empirical investigation about the key elements of physics modeling competency,and it mainly focuses on the four aspects:firstly,determining the meaning of physics modeling competency;secondly,constructing the framework of the elements of physics modeling competency;thirdly,investigating and analyzing the status quo which students' physics modeling competency is cultivated in senior middle school in China;fourthly,the strategies for the cultivation and improvement.This thesis mainly discusses the following aspects:The first part is theoretical study which is composed of the first,the second and the third chapter.The first chapter mainly elaborates the research background,the content,the method,the design and so on.In this chapter,we determine to study the construction of the modeling competence under the specific discipline of physics.In the second chapter,we discussed the related research in four fields from the study of intellectual structure,the research of modeling competence structure model,the teaching research of cultivating students' modeling competence and the research of modeling competence evaluation.The third chapter defines four core concepts of this thesis:model,modeling,physical modeling and physical modeling competence.The theoretical basis of this thesis includes Spearman's intellectual two-factor theory and Wechsler's "intellectual non-intellectual factors"theory,Schwarz's scientific modeling competence structure theory,Hestenes' physics modeling cycle teaching theory,Halloun modeling process model theory.The second part is empirical research,composed of the fourth chapter and the fifth chapter.In this part,we construct the framework of the physics modeling competence structure by using the Grounded theory research method based on the related theory and the fact material.And we design the questionnaire based on the framework to investigate the current situation of the senior high school students' modeling competence.The fourth chapter,we use the Grounded theory research method to construct the physics modeling competence constituent elements framework,and use the scientific knowledge map method to test the reliability of the framework.We selected 35 subjects with high physics modeling competency in physics and other natural science sub-disciplines(eg.chemistry,geography,astronomy and biology),interviewing them one by one using an interview outline about psychological activity and behavioral characteristics.The interviews were mainly about their psychological and behavioral characters and the growing course of these 35 subjects'scientific modeling competency.We picked up 3663 expressions which can represent physics modeling competency in the interview record which containing more than 300,000 words by following the strategies of Charmaz's Grounded theory.Through the initial coding,focused coding and axial coding,we categorized these expressions according to the logical relationship,and generalized the framework of the elements of physics modeling competency from the categories.There are 11 key elements which attributed to construct physics modeling competency in 3 dimensions.It includes the Non-cognitive factor of modeling,the basic competency factor of modeling,the special competency factor of modeling.The Non-cognitive factor of modeling includes discipline interest,success motivation,and character trait.The basic competency factor of modeling includes analytical ability,transfer of learning,self-development ability,and communication&cooperation.The special competency factor of modeling includes knowledge of discipline,special experience,model thinking and meta-modeling knowledge.Through drawing "modeling competency" scientific knowledge map,we summarized the high-frequency,strong-center,high-burst keywords which reflect the physics modeling competency.On this basis,this thesis analyzed the elements of modeling competency which domestic researchers have focused on.And then we extracted the principal component of the physics modeling competency and carried out the principal component analysis to obtain the contribution rate of the cumulative variance of the principle component.Based on the contribution rate,we proved the qualitative research conclusion has a higher reliability.In the fifth chapter,the investigation and analysis of the status quo which physics teachers cultivate senior high school students' physics modeling competency are carried out.In addition,we also provided a quantitative analysis of the current standards of primary school science curriculum,junior high school science curriculum,junior high school physics curriculum,senior high school physics curriculum.This result provides evidence to support cause of the problems which schools and teachers cultivate student's physics modeling competency.The third part is the cultivating strategy and the recommendations of the thesis,consisted of chapters 6 and 7.In the sixth chapter,based on the results of questionnaire survey and curriculum analysis,we analyze the current outstanding problems and puts forward the strategy of school cultivating students' physics modeling competence.In chapter 7,we summarize the research work of this thesis,including the research conclusion,the innovations of the research and the prospects of the next step.
