Design Research On Open Chemistry Problems

Open questions play an important role in improving students' innovative ability.The study of open questions has become a hot topic in the new era.In the context of the new chemistry curriculum reform,scholars have focused on the design and compilation of open chemistry issues as a "breakthrough" in open chemistry research.This study starts from the formal characteristics of the conditions,methods and open conclusions of open questions,compiles and conducts open measurement of chemistry open questions,and selects typical subjects to conduct in-depth interviews in order to make suggestions on the design of open chemistry questions.This study sorted out and reviewed the relevant literature on open chemical issues,defined the connotation and characteristics of open chemical issues,combined seven design types of open chemical issues,and compiled a questionnaire for open chemical issues.Taking 320 students in the first grades of two ordinary senior high schools in Shandong Province as the research object,the actual measurement was carried out with the open chemical questionnaire.Collect and process survey data,correct and assign questionnaires,select effective questionnaires according to the questionnaire response,use SPSS Statistics 21.0 statistical software for quantitative data management and analysis,and grasp students' solutions to different types of open chemical problems.Determine the outline of the interview,select 7 participants for in-depth interviews,translate the recorded materials into documents for qualitative analysis,and test the students' explanatory knowledge of open problems in chemistry.Finally,combined with the results of quantitative analysis and qualitative research,understand the process of solving students' open problems in chemistry,and then explore the design of open problems in chemistry.The research results show that:(1)the greater the degree of openness of chemistry questions,the better the fluency,flexibility,and creativity of students 'responses;(2)the openness of problem representation and problem gathering space affects the opening of students' chemistry The important characteristics of sexual problem solving;(3)The knowledge content contained in the test questions will affect the solution of students' open problems in chemistry.The innovations of the thesis are mainly reflected in:(1)The questionnaire of chemical chemistry openness questionnaire,which provides a new tool for future research on chemical chemistry openness question;(2)Propose the solution to the problem of chemical chemistry openness The factor is innovative and provides a theoretical basis for the open problem of design chemistry.
