A Qualitative Study On The Solution Of The Chemical Balance Problem Of Gifted Students In Senior High Schools

"Change concept and Equilibrium thought" is one of the five important content dimensions of the core accomplishment of high school chemistry discipline,and chemical equilibrium is also a difficult knowledge of high school students ’ chemistry learning.In learning the knowledge of chemical equilibrium,students will encounter many learning difficulties,resulting in a chemical equilibrium of the myth concept.This paper studies the behavior of solving the problem of chemical equilibrium in gifted chemistry,analyzes the mental operation of students to solve the problems of chemical equilibrium,and puts forward some suggestions for the study of students ’ knowledge of chemical equilibrium.This study first combs and reviews the literature on chemical equilibrium,analyzes the knowledge of chemical equilibrium textbooks,determines the relevant concepts and knowledge involved in chemical equilibrium,and draws the concept map in combination with expert opinions.According to the research needs,the chemical equilibrium Survey questionnaire was compiled,and based on the results of chemistry and mathematics examination,combined with the recommendation of the teacher and the head teacher,the evaluation of the classmate was assisted,and 6 gifted students were selected as the research object in 105 sophomore science experiment Class of a general high school in Shandong province,and the method of thinking aloud was adopted.To carry out the measurement of the Chemical Equilibrium Survey questionnaire,and to translate the recorded content into the oral report,from the results of solving the problem,the concept of chemical equilibrium and the use of the theory,the basic skills of solving problems,problem-solving behavior and strategies to analyze the oral report data,in order to understand the students on chemical equilibrium related knowledge reconciliation skills understanding and application And analyze the factors that affect the success or failure of sophomore science gifted.With the help of empirical research results,chemistry teachers have a deeper understanding of gifted students,so as to adopt more effective teaching methods and strategies,guide them to think and solve chemical problems,and then develop targeted courses,so as to provide some assistance to the potential of mining gifted students.The research shows that:(1)Correct problem characterization is an important factor affecting the success of solving problems;(2)The successful solving process is a meticulous process of analysis and reasoning,and(3)the correct application of the concept and principle of chemical equilibrium is the key to successfully solve the problem of chemical equilibrium.The innovation of this study: first,the compilation of Chemical equilibrium survey questionnaire for the future chemical equilibrium of the practical study provides a new tool to be used for reference;second,the preliminary study shows that problem characterization,programmatic analytical reasoning and chemical equilibrium principle and concept application are important factors affecting the solution of chemical equilibrium problem of sophomore science gifted.This also provides some empirical data for further research on the solution of chemical equilibrium problem.
