The Level Of The Primary Data Processing Capacity Study

Data Processing capabilities have become one of the important contents in the primary and secondary mathematics curriculum.China published the Obligation Education Mathematics Curriculum Standards in 2001,proposing some requirements about the Data Processing in the first and second stages,such as able to select bar charts,line charts intuitive,that represent the data effectively.As a kind of new content coming into the elementary mathematics curriculum,the deep research is so necessary about theory,curriculum design,teaching practice and so on.The author thought that there are two questions worthy of further discussion as following:(1) How to divide the level of Data Processing capabilities in first and second stages? (2)How different backgrounds impact Students' data processing capabilities?From the perspective of mathematics curriculum,this article has revealed the mathematics nature about data processing,and also analyzed the Standard's requirements about data processing.After that the author has made some presuppositions about the different level about the data processing capacity between the two stages,and then developed the test framework and some items about the data processing.According to the results of test the author has described and analyzed the features of each level objectively and also calibrated the presuppositions;at the same time the author has pointed out some questions,that reason has also be analyzed.On the base of the results of this research,the author has provided some recommendations for curriculum design,teaching,learning and evaluation about the data processing curriculum.The test about students' data processing capabilities in this research has been evaluated from two aspects such as data processing's knowledge and consciousness. At the same,the author studied 'different backgrounds impact Students' data processing capabilities'.According to the analysis of the mathematics nature about data processing,the data processing has also been further divided into three sub-dimensions,such as organizing the data,Describeing the data using charts, Describeing the data using number.This research has answered the following two questions:(1) How to divide the level of Data Processing capabilities in first and second stages and how about the concrete performance of different levels?(2)How different backgrounds impact Students' data processing capabilities? After the test the author has also interviewed with some students and teachers about some typical mistakes and problems to find out the reasons.Finally,with the results of the investigation,the author has provided some specific recommendations for curriculum design,teaching,learning and evaluation about the data processing curriculum.Sincerely hope this research will lead to more thought and discussion about the estimation curriculum.
