The Factor Analysis And Survey On The Development Of Senior High School Students Chemistry Calculation Capacity

Chemical calculations are from the amount perspective of understanding andknowledge the composition and variation of chemical substances, chemical calculation isthe basic chemical knowledge and the integration of basic skills，not only to deepen theunderstanding of chemical knowledge, but also to train numeracy skills. Because theflexible and diverse of the chemical calculations problem, the chemical computing capacityof many students not reach the teaching requirements, and can not skilled in using theirknowledge to solve the problem of chemical computing class. So study the influencefactors of chemical computing power development is extremely important.In this study, the influencing factors to the students’ chemistry computing power as itstheme, is mainly explained the contents of four parts:First, by consulting the relevant literature and existing problem-solving research，determine that the factors affecting the high school students chemistry computing powerhave problem representation, knowledge level , strategy choice and numeracy skills.Second，Through the preparation of the questionnaire survey, interviews and thinkingaloud method. Survey 50 high school students of chemical computing power status quo.By statistical analysis showed that: the above four categories of factors on the developmentof the students chemical computing power have significant effect. Deep characterization ofthe core of the chemical development of computing power, Strategy for optimization is thekey to the development of chemical computing power, Understanding of knowledge is thebasis for the development of chemical computing power, Numeracy skills is the protectionof the chemical development of computing power.Third, according to survey data and teaching practice, proposed some teachingsuggestions to culture of the computing power of high school chemistry，in order toprovide the teachers with effective help.In the end, we discussed and prospect the problems existing in the thesis.
