An Empirical Study Of Applying Logical Reasoning Ability To Effectively Solve The Calculation Problem Of Chemical Equilibrium

At present, in the domestic chemical education research shows, in high school chemistry, chemical equilibrium calculation is a difficult problem for senior high school chemistry learning, students is hard to solve the chemical equilibrium calculation problem. Teachers how to use the students’knowledge, experience and basic cognition, and combined with the characteristics of the knowledge of chemical equilibrium, find out the causes and breakthrough this problem in the teaching of chemical equilibrium calculation has become a significant research topic. For the above, access to large amounts of information and the actual findings, logical reasoning ability in solving chemical equilibrium calculation is significant. In this research, how to use logical reasoning ability effective solving chemical equilibrium calculation problem and change the chemical equilibrium calculation problem as the current situation of the teaching difficulties.The article is divided into six parts:The first part introduces the research background, purpose, significance, research ideas and methods. And details of relevant chemical equilibrium new curriculum courses standards and the college entrance examination syllabus requirements.The second part introduces the researches on chemical equilibrium problem-solving with logical reasoning ability. Theoretical Study on the present status of chemical problem-solving, secondary school students thinking development are also described.The third part describe the related concepts and theoretical basis.The fourth part is the focus of the content study, to analyze the chemical equilibrium test scores of the session high school students from Huizhou City, Guangdong Province, chemical equilibrium calculation problems is found indeed a difficulty for their learning. In addition to the level of some students’logical reasoning test, combined chemical results found logic levels on chemistry learning has a strong positive correlation. Also combined with the students’ answer to the Guangdong College Entrance Examination in chemical equilibrium calculations in recent years, analyze the factor of chemical equilibrium learning difficulties.The fifth part is an important part of the study, this part is made to solve the problem of chemical equilibrium calculation with logic reasoning strategy based on the results of the fourth section. And by some of the best students of the problem solving process and analyze the logic thinking strategies (deductive strategy, induction strategy, analogy policy) is effective. It also moved to how to use the policy to solve the water solution in the chemical equilibrium calculation problems.The sixth part of the paper summarizes the results and reflection of research.
