The Diagnosis And Correction Of Chemical Balance Problem Solving By Senior Two Students

The report of the 19th National Congress puts forward the following proposals: to implement the Party's educational policy in all respects,to carry out the basic task of establishing morality and fostering people,to develop quality education,to promote educational fairness,and to train socialist constructors and successors who have all-round development of morality,intelligence,Physique and the United States.The background of the new era has higher requirements and testing standards for chemical education.It is a great challenge for teachers and students nowadays that the school pays more attention to the cultivation of comprehensive and applied talents.The traditional educational thinking and method pay more attention to the score and the transfer of knowledge,but not to the application of knowledge,which leads to a disadvantage of studying one problem for another problem,especially in the problems of chemical equilibrium.The knowledge of chemical equilibrium is abstract and comprehensive and the questions type of chemical equilibrium in recent years are flexible and changeable,but there are some problems in students' cognition and understanding.At present,most of the students still have barriers to the learning of this part.In this thesis,the students of NO.31 Senior High School in Urumqi are the main research bodies to study the problem.The full text is divided into four parts.Part One,Introduction.It mainly includes three parts.Firstly,the research background and research significance of the subject are introduced.It was found that the diagnosis and correction of chemical equilibrium problems should be solved urgently.Then through literature research,it does not only analyze the current situation of education of chemical equilibrium module and the means of educational diagnosis,and reading and integrating a large number of literature on Chemical equilibrium Education diagnosis at home and abroad,but also defines the core concepts in the research process,summarizes the research status athome and abroad,and concludes that it is difficult for students to study the chemical equilibrium module.This study used several effective ways to do the research,including literature analysis,questionnaire survey,test,and work analysis.At last,formulate a corrective plan.In the second part,to carry out an investigation.By conducting an investigation and research on the problem from three aspects: interest,interview and questionnaire test.This paper classifies the interest survey questions from the senior two students' interest in learning chemistry,from the state while they were in class,previewing,reviewing counting as well as learning difficulties.And I also collect the interview content of the students.Correcting the test paper and counting the percentage of the options of each topic.Finally analyze the reasons for some several typical and common problems in the study.Part Three,analyze the survey statistics.This paper makes full use of the results of the survey,focusing on the obstacles that exist in senior two students in four aspects: Solving Chemical equilibrium Problems,mastering knowledge points,calculating ability and thinking ability to conduct comprehensive analysis and propose solutions.The fourth part is conclusion and reflection.On the basis of the new curriculum standard,this paper makes a teaching diagnosis of chemical equilibrium problems and puts forward some practical suggestions for the first-line educators.Based on the problems in the implementation of this study,this paper puts forward some reflections and suggestions.
