Research On The Open Problem-solving Behavior Of High School Students With Different Concepts Of Chemical Change

The open question was first put forward by Shimada group of Japan when they studied mathematics problems,and then became a hot topic in the field of education and teaching.To carry out the research of open problem solving behavior can help teachers to better understand the students' open problem solving situation,so as to create an efficient classroom.The concept will have an impact on people's behavior,and the students' chemical concept will have a certain impact on the solution of their open problems.In this paper,a survey questionnaire for the concept of chemical change and a survey questionnaire for the concept of chemical open problems are compiled.Through the actual measurement,the paper explores the high school students' chemical open problem-solving behavior with different concept of chemical change,in order to put forward suggestions for students to solve the problem of chemical open problems Suggestion.In this study,students from six classes in grade two of two key senior high schools in Shandong Province are taken as the research objects,and different types of chemical openness problems are integrated.Combined with the research needs,a chemical openness problem-solving questionnaire is developed to test the subjects' chemical openness problems.SPSS and other statistical software were used to further analyze the specific situation of solving the problem of chemical openness.Combined with the basic connotation of the concept of chemical change in the new curriculum standard,a questionnaire of the concept of chemical change was developed,and the development level of the concept of chemical change of the subjects was distinguished based on the overall implementation of the questionnaire.Based on the subjects' daily chemical performance and language expression ability,six students with good performance and good communication ability were selected from the top 25% of the students in the questionnaire.After the interview,the collected recording materials were transcribed and analyzed One step is to explore the specific influence of the concept of chemical change on the open problem-solving behavior of senior high school students.The results show that:(1)the concept of chemical change will affect students' problem representation;(2)the concept of chemical change will affect students' search of problem space;(3)the concept of chemical change will affect students' metacognitive monitoring of problem solving.The innovation of the research are as follows:(1)the questionnaire of chemical open questions and the questionnaire of chemical change concept,which provide a new tool for the later testing of chemical open questions and chemical change concept;(2)the paper puts forwardthe problem representation,problem space search and metacognitive monitoring of chemical change concept affecting the open questions of senior middle school biochemistry It provides a new basis for open question teaching.
