Research On Misconception Diagnosis Based On Fourth Order Measurement ——Take "periodic Law Of Material Structure Elements" As An Example In Chapter 4 Of High School Chemistry Of Human Education Edition

Misconception refers to the concept or idea that learners have which is not completely consistent with the scientific concept or deviates from the nature of scientific phenomenon.High school students will have incorrect understanding of many concepts in the process of learning chemistry,and the reasons for these myths are also different.For example,people have accumulated experience in life,and some people have incorrect understanding of correct concepts influenced by more than one factor in the learning process.For example,when they acquire knowledge,they are misled by some factors,they misunderstand concepts and examples in textbooks,and negative transfer of subject knowledge.Once a myth is formed,it takes root in the brain,is easy to remember,and does not disappear over time.The existence of myth will affect the learning effect,so myth has always been a hot topic in education research.In this study,four-section measurement method was used as the research tool.Taking the fourth chapter "Periodic Law of Material Structure elements" as an example,four-section test questions were compiled to test the students of provincial key high schools,municipal key high schools and ordinary high schools in Harbin.And test results analysis,accuracy analysis,confidence index analysis and students learning this chapter in the process of the misconception diagnosis,at the same time to test the four-section measurement method in the diagnosis of the misconception research.The final research conclusion: three schools students in the atomic structure and the periodic table of elements,element periodic law,chemical bonds the myth of the common concept of three topics,students in the chemical bonds subject concept of myth,the most and the study found that four-paragraph measurement as a diagnostic tool in the study of the misconception has a good practicability.The innovations of this paper are as follows :(1)based on 2-phase measurement method,the three-step measuring method,on the basis of the introduced respectively after the answer and reason for confidence,four-paragraph measurement method to diagnose the students in the "material structure element periodic law" part of the myth of the existence of concepts,and inspection four-paragraph measuring method in the diagnosis of the scientific nature of the concept of myth;(2)Compare the degree and distribution of the misconceptions among the students of provincial key high schools,municipal key high schools and ordinary high schools in Harbin,and promote the students' understanding of the concepts;(3)It enriches the content of high school chemistry misconception diagnosis and provides reference and suggestions for high school chemistry teaching.
