Research On Thinking Obstacles And Breakthrough Strategies Of Senior High School Students In Solving Chemical Industrial Process Questions

With the further development of the new curriculum reform,chemistry in the college entrance examination is more and more combined with reality production and life.From the analysis of the high test papers in recent years,the "chemical industry process problem",which is closely related to chemical production,has become a hot topic and a mainstream topic.From the point of view,this kind of question type is very comprehensive,can be said to be both the experiment topic,the picture problem,the calculation problem is also a deduction analysis problem.This not only requires students to familiar with all kinds of textbook knowledge,learn to information processing and processing,at the same time also require students to pay attention to in the social development related to the chemical technology,and the harmonious development of the ecological environment.So the majority of students are afraid of this kind of topic,have no way to go,the score is very low.If we can find the student in the teaching of thinking obstacle in the treatment of the industrial process problem of,studies and sums up the effective teaching methods and strategies,then will be able to greatly improve the students' first,reduce the fear of students studying chemistry,improve the learning interest and level.This study focuses on "What is the chemical process problem'","What are the thinking barriers for students to solve the chemical process problem",and "What are the strategies for breaking through the thinking obstacles in the chemical process?",through the literature survey method,the questionnaire survey method and the interview survey method,to start the research.This research paper is divided into five chapters:The first chapter is the introduction.It mainly introduces the background and significance of the research,emphasizes the content of the research,the ideas,and the research methods used.Through the study of literature,Summarize the scholars 'analysis and understanding of the chemical process problem,explain the structure,type,characteristics and functions of the chemical process problem,and analyze and summarize the chemical process problem that appeared in the college entrance examination in the past five years.The second chapter is the definition of the relevant concepts and theoretical basis.This paper summarizes the classification of thinking characteristics and mental disorders of high school students,and combs the problem solving theory,cognitive diagnosis theory,and SOLO classification theory.The third chapter is the investigation and analysis of the thinking obstacles of high school students in solving such problems.It describes the methods of questionnaire survey and interview,and deals with and summarizes the data as a whole,thus obtaining information.The fourth chapter is the strategy research,combined with the problem of the response in the investigation,put forward the relevant strategies to break through the chemical process problem.The fifth chapter is the conclusion of this study,introduces the results of the study,and reflects on the relevant implications and shortcomings of the research on teaching work.Through the research and investigation of the subject,the following conclusions are drawn:Students' thinking obstacles in dealing with industrial process problems are mainly unfamiliar to the knowledge points.Weak ability to process information and process information;Psychologically there is a shadow of resistance and panic on this subject.Therefore,it is suggested in the following teaching that teachers can improve students' interest in studying chemistry through experiments or how to relate to chemistry in daily teaching.Build knowledge network and systematize the knowledge of high school,especially the elements and their compounds;To pay attention to the study of chemistry and technology in human education edition;Strengthen the training of the process problems,be familiar with the way of examination,and improve the speed and ability of the problem.A multi-purpose question,multiple questions and one use,layer-level migration,expand the student thinking space.
