The innovation ability of chemical transfer reflects the requirement of the core accomplishment of chemistry discipline,and involves the advanced output of knowledge and experience in the content.Improving students’ innovation ability of chemical transfer is the requirement of the educational reform in the new era and the cultivation of innovative talents.Thinking set is an important factor affecting transfer and innovation,which has positive and negative transfer effects in chemistry learning,and the negative transfer effect is often more prominent.Eliminating students’ thinking set is of great help to improve the ability of transfer and innovation.The research question of this paper is to investigate the overall status quo of high school students’ chemistry subject transfer and innovation ability,build a teaching model to eliminate thinking set on the basis of rich theoretical basis,and test the effectiveness of this teaching method in improving students’ chemistry subject transfer and innovation ability through teaching practice and interview survey.Finally,some teaching strategies are proposed to eliminate the negative transfer of thinking set and cultivate students’ ability of transfer and innovation.This paper consists of five parts: the first part is the introduction,which expounds the background and significance of the research,sorts out the literature review,summarizes the research status at home and abroad on migration innovation ability and thinking set,and clarifies the research content,framework and methods;The second part is the theoretical basis and concept definition,with the purpose of clarifying important related concepts,sorting out the transfer theory,discussing the process of knowledge transfer and the mechanism of thinking set affecting the transfer,as well as the classification and causes of thinking set in chemistry teaching,and analyzing the influence of thinking set on students’ chemistry learning through specific cases.Based on this,the schema destruction teaching method is proposed to eliminate the thought set.The third part is the compilation of test papers,referring to Professor Wang Lei’s basic evaluation index of chemistry subject migration innovation ability,based on the evaluation index system,the compilation of test questions and test their reliability and validity.Then the test was carried out,and the test results were statistically analyzed from the perspectives of the overall situation,student gender and achievement.The fourth part is teaching practice.Combining the performance,classification and causes of thinking set in chemistry learning,it puts forward the teaching strategies to eliminate thinking set and improve the innovation ability of chemistry transfer of senior high school students.In combination with schema destruction teaching method,curriculum design was carried out with "REDOX reaction" as an example,experimental class and control class were set up,and the development and change of chemical migration innovation ability was investigated again.Variance analysis was conducted on the results of questionnaire survey of the two classes.Interviews with teachers and students were conducted to determine the effect of schema destruction teaching method on students’ thinking and the effectiveness of improving students’ ability of chemical transfer innovation.The fifth part mainly expounds the conclusion,innovation and shortcomings of this research,and makes a prospect for further research.The findings are as follows:1.In this study,the Test Paper of Chemical Migration Innovation Ability of High School Students(Volume A)and the Test Paper of Chemical Migration Innovation Ability of High School Students(Volume B),which are designed in this study,involve three ability elements: complex reasoning ability,systematic inquiry ability and innovative thinking ability.Three large questions are used to investigate,with full score of 60,and the overall reliability and validity of the two sets of questionnaires are good.2.The analysis of the questionnaire shows that the overall status of the innovation ability of chemical migration of senior high school students is general and at a medium level.Among them,the ability of systematic inquiry and complex reasoning is relatively good,while the ability of innovative thinking is relatively weak.In addition,high school students’ innovation ability of chemical transfer has significant differences due to different grades,but in the gender of high school students,the difference is not obvious.3.After constructing schema destruction teaching method and conducting teaching practice,it is found that after four class hours of training course,students’ innovation ability of chemical transfer has been slightly improved in general,but the improvement amplitude of the three dimensions is slightly different.It shows that the cultivation of students’ innovation ability of chemical transfer is a long-term process.Interviews with teachers and students show that they agree with the model,that is,the teaching model constructed can effectively eliminate the thinking set and improve the students’ ability of chemical transfer and innovation.4.According to the specific performance,classification and causes of the negative transfer effect of thinking set in chemistry learning,this paper puts forward targeted teaching strategies: teaching based on variable training,teaching based on effective failure and teaching based on problem solving,aiming at eliminating students’ thinking set and improving their ability of chemical transfer and innovation.This study provides a tool for evaluating the innovation ability of high school students’ chemical transfer,and provides specific measures and strategies for eliminating students’ thinking set and improving their innovation ability of chemical transfer,so as to guide the chemistry learning of high school students,improve the teaching quality of chemistry teachers in first-line middle schools,and apply theoretical research in teaching practice.At the same time,it is also found that there is still more research space in the strategic direction of improving the migration innovation ability of chemistry,and further research can be done to improve the migration innovation ability of chemistry. |
