Research On The Influence Of High School Students' Chemical Experiment Operation On Their Psychological Safety

As we all know,chemistry is an experimental-based discipline.Chemistry experiments are extremely important for students to study chemistry.They can stimulate students' interest in learning,help them form chemical concepts,consolidate chemical knowledge,acquire chemical experiment skills,and cultivate practical and realistic ideas.Serious scientific attitudes and training of scientific methods.The process of chemical experiments has great complexity,variability and danger.Therefore,the complexity,variability and dangerous chemical experiment process will have a great impact on students' psychological safety.Therefore,the study of the impact of high school students' chemistry experiment operations on their psychological safety provides scientific and valuable advice for subsequent teaching.This study is first to ask questions,to explain the background of the research and the significance of the research;Then comb and analyze the related literatures on psychological security,chemical experiments,and the relationship between psychological safety and chemical experiments,determine the concept of psychological security,and explain its meaning;Based on the connotation of psychological safety,combined with the specific chemistry experiment operation of students,the questionnaire of the influence of experimental operation on the psychological safety of high school students was compiled.The 430 Students in the first and second grades of high school affiliated to Qufu Normal University were selected as the research objects.Collecting and collating the survey data,using SPSS21.0 statistical software for data analysis: On the one hand,the corresponding analysis of the data results,and draw conclusions,on the other hand,from the two aspects of students and teachers A suggestion for a sense of security in the Chemical Experiments Operations Center.research shows:(1)The safety of experimental operations will have an impact on students' psychological safety.In general,the higher the safety of the experimental operation,the stronger the psychological safety of the students.(2)The degree of complexity of the experimental operation will have an impact on the psychological safety of the students.In most cases,the simpler the experimental procedure,the stronger the student's psychological security.(3)The normative nature of experimental operations will have an impact on students' psychological safety.In general,the more standardized the experimental operation,the stronger the psychological safety of students.The innovation of the thesis is mainly reflected in: Firstly,from the perspective of chemicalexperiment operation,combined with the specific operation of the chemical experiment process,the self-made high school students' experimental operation has a certain innovation on the psychological safety impact questionnaire;Through the research on the chemical experiment operation of high school students,the impact on their psychological safety is analyzed,which has certain novelty.This study provides a reference for the chemical safety of chemistry teachers in chemistry teachers.
