"Amount Of Substance" Thematic Knowledge For Solving Fault Analysisand Countermeasure Research To Solve Problems

Amount of substance is the first volume of high school chemistry knowledge, is the whole one of the most important content of high school chemistry knowledge system, the always throughout the chemistry learning, especially in the chemical calculation of amount of substance is at the core of knowledge. In the amount of material in the college entrance examination project content and related knowledge is necessary to test every year, so for students to learn chemistry, to learn the knowledge of project is very important. In the amount of material project learning teachers spend a lot of effort in the teaching, but in this part of the students in the process of problem solving a lot of errors, and to make the title of miss next time doing when the error rate is still high. So students in the process of amount of substance thematic learning an error what is the cause of the problem solving? How to solve the high student in the amount of material project learning problem solving wrong? This is to key research issues in this paperThis article is based on a large number of teaching on the basis of theoretical research on high student material under the condition of the amount of project learning, No.1High School Affiliated to Central China Normal University, the first grade four class as investigation object, USES the literature material method, interview method, questionnaire method of identifying markers, data statistics, the volume of the project learning of higher material problem solving fault from the perspective of learning theory and teaching practice research discusses through the rational analysis and scientific summary of the high student physical volume of the project learning problem solving wrong because of the nature of reason, and combined with relevant theory and empirical studies so as to suit the remedy to the case teaching practice put forward the corresponding teaching strategies which could serve as the majority of teachers and education workers practice teaching reference.Full text is divided into six chapters. The first chapter is introduction, introduces the content of this study and research the necessity of introducing the related research and research status at home and abroad; The second chapter of the wrong topic related concepts and related theory of study; The third chapter introduces the practice research process of the investigation and statistics of the questionnaire; The fourth chapter, according to the results of the empirical survey analysis high student in the amount of material project learning problem solving the cause of the error; The fifth chapter in combination with related based on the results of theoretical analysis and empirical investigation forward related countermeasures to solve the problem solving error; This chapter6studies the reflection and summarized.
