| Mathematical computing ability is one of the three basic abilities of traditional mathematics.It is also one of the ten core words proposed in the "Compulsory Education Mathematics Curriculum Standards(2011 Edition)",and is also included in the "Ordinary High School Mathematics Curriculum Standards(2017 Edition)".of the core literacy,the cultivation of computing ability can promote the development of mathematical thinking,form a good habit of standardizing thinking problems.Understand the current situation of students' calculations,analyze typical operational errors,extract the influencing factors and propose targeted strategies.The key to the development of computing power is based on the following three questions: 1 to build a high-student mathematics computing ability evaluation model,according to the model to prepare test papers;2 to conduct test papers and questionnaires for students,Analysis and calculation status;3According to the analysis results,the influencing factors of computing power are extracted,and the training strategy is given in a targeted manner.Based on the above research questions,the author uses literature analysis,test paper test and questionnaire survey and statistical analysis research methods.First,the concept,structural elements and level division of mathematical computing ability are reviewed,with reference to Professor Cao Yiming of Beijing Normal University.“Performance Theory Model” and Sun Ting's “Three-Dimensional Evaluation Framework for Mathematical Theory of Theoretical Competence”,the three-dimensional evaluation framework for mathematics computing ability is constructed from the three dimensions of subject content,ability structure and level.Secondly,it will be compiled.The test papers and questionnaires were tested for reliability and validity,and formal tests were conducted on XZ city two parallel classes of three experimental classes in the first year of a school,collecting and collating data,and using SPSS.21 and EXCEL software to analyze the status quo(The current situation of the high school students' computing ability level,the difference in the degree of mathematics achievement,the difference in the ability of students with different genders,and the typical operational errors in the test paper).After the test paper analysis,the current situation of the XZ city high school students' computingability is obtained: 1 the overall computing level of the students is not high,and the computing power is positively correlated with the mathematics scores;2 the computing power has no gender difference.Then through the typical error analysis of the students in the test paper,the students are explored.The weakness of computing power: 1 students' attitudes are not correct,lack of interest and other mental abilities;2 basic concepts such as computational concepts,formula theorems are not reliable;3 can not select appropriate thinking methods according to the characteristics of the topic,use mathematical strategies.In summary,the conclusions of this study are as follows:(1)The mathematics computing ability of students can be measured.The mathematical computing ability evaluation model of this study has certain feasibility.(2)According to the analysis of test papers,the influencing factors of XZ city computing power are the individual psychological factors of students.Mathematical operation knowledge cognitive structure factors,mathematical thought methods and teachers;(3)based on the influencing factors,from the perspective of students and teachers,it is proposed to raise the mathematics computing ability of high school students,that is,to pay attention to non-intellectual factors Positive effects on students' mathematical operations,improve the cognitive structure of mathematics knowledge,improve the rationality and accuracy of computing,pay attention to the optimization of students' thinking quality,improve the flexibility and simplicity of computing,improve the professional quality of teachers,and strengthen their demonstration effect. |
