Theoretical And Practical Research On Cultivating Senior High School Students' Chemical Reverse Thinking

In the current era,the country's demand for innovative talents is getting higher and higher,and students' thinking is a major factor in determining whether they can innovate.It requires students to have certain innovative thinking abilities.Reverse thinking is an important part of innovative thinking,and it plays an important role in the cultivation of innovative thinking ability.For students,the cultivation of reverse thinking can also help them overcome stereotypes and broaden their ways of thinking,etc.In recent years,some experts and scholars have begun to pay attention to the chemistry review class,continue to explore the review mode,put forward novel insights and carry out specific teaching practices,which makes the chemistry review class have a leap-forward development.Looking at these new viewpoints and theories,it is found that the research focus is on the thinking training in the chemistry review class.Therefore,it is very necessary to carry out research on the cultivation of reverse thinking in the high school chemistry review class.The research is divided into the following parts:The first part is the introduction.It puts forward the research purpose and significance,sorts out the research ideas and clarifies the research content,and determines the methods for carrying out this research: literature research method,questionnaire survey method,teacher interview method and action research method.The second part is to consult relevant domestic and foreign documents,sort out the current situation of reverse thinking and chemistry review class,and summarize the current hotspots and deficiencies of current teaching research.At the same time,this part also defines the concepts of �thinking� and �reverse thinking�,and elaborates the theoretical basis of the research in this article.In the third part,a questionnaire was designed to investigate the current situation of reverse thinking in high school chemistry classrooms,and found that there are problems in the current classroom: teachers have certain theoretical knowledge for the training of reverse thinking in chemistry class,but they are not very motivated in actual teaching,especially in review classes;students have a certain foundation of reverse thinking,but there is still room for improvement,and teachers need to be conscious to guide them.The fourth part is theoretical research.It proposes the teaching mode of cultivating students' reverse thinking with �inspiration link ? orientation link ? execution link ?deepening link ? feedback link� as the main teaching process in the chemistry review class,and based on this,the corresponding lesson examples are designed,and the teaching strategy of cultivating reverse thinking in the chemistry review class is proposed from the three aspects of concept law,experiment and exercises.In the fifth part,teaching practice is carried out to test the effectiveness of teaching strategies and teaching models,and two classes with similar starting levels are selected to carry out teaching experiments.After the one-semester teaching experiment,draw conclusions through the issuance and statistics of test papers and questionnaires,it is concluded that the review teaching model and strategies proposed in this study can help improve students' chemistry academic performance and stimulate students' interest in chemistry review courses.Finally,the article obtains the conclusions from the research and discusses the achievements and innovations of this research.And also we reflect the deficiencies and bring up the prospect of the research.
