Diagnosis Of The Obstacles In Solving The Problems Of Chemistry Calculation For Senior One

The essence of chemical calculation problems is the mathematical processing of chemical problems,that is,the process of quantifying the composition,structure,properties and changing laws of substances.Carrying out effective chemistry calculation problem-solving obstacle diagnosis is a prerequisite for realizing students' individualized teaching.If they can accurately diagnose the causes of obstacles in solving chemistry calculation problems for students of different categories,they can better prepare for students Targeted instructional design and chemistry calculation exercises.The combination of diagnosing different types of students' obstacles in solving chemical calculation problems and information technology to establish a chemical calculation problem diagnosis system can quickly diagnose the differences in obstacles among different types of students.The main theme of this study is to solve the types of obstacles and deep-seated causes in the process of chemical calculation problems.It mainly explains four parts:First,by referring to relevant literature and existing research on chemistry calculation problem solving obstacles,the obstacles affecting high school students' chemistry calculation problem solving are identified as follows: question examination obstacles,thinking obstacles,knowledge obstacles,computational Obstacles and psychological disorders.Second,through the preparation of diagnostic papers,analytical papers and questionnaires,using statistical analysis methods,interview methods and other research methods,105 high school first-year students were analyzed when they encountered obstacles in solving chemical calculation problems(Different classes,different genders,and different academic levels)perspective analysis and comparison of differences in the types of obstacles in chemical calculation problems.Thirdly,based on the survey data and empirical research,it proposes solutions to the obstacles that arise in the chemistry calculation class,which helps teachers better teach and students learn better.Fourth,the implications of conducting this study to us are discussed.
