Survey And Research Of Sexual Difference Of Junior Middle School Students' Understanding Ability Of Statistical Graphs

In take the information and the technology as in the foundation society, the data becomes one kind of important information day by day.In order to understands the world well, the people must learn to process each kind of information, in particular numerical information.The collection, the reorganization and analysis information ability has become the information age each citizen basic accomplishment a part. The statistical graphs is some chaotic data visualization, through to statistical graphs understanding, the people may analyze obtain some correct conclusions.Understood the male female student's in statistical graphs understanding difference, through the curriculum and the teaching, can effective avoid the male female student's in mathematics study difficulty, can have some models and the help to the junior middle school probability statistics curriculum and the teaching.The author will conduct the research to the below question: (1) junior middle school male, female student to several kind of commonly used statistical graphs. (2) creates this kind of present situation the reason analysis.(3) Aavoids this kind of sex difference for the reduction, the union statistical chart teaching, counts the curriculum to the junior middle school the establishment and the classroom instruction puts forward some proposals.The research from the test questionnaire survey, the non-intelligence factor questionnaire survey, unifies author's teaching to practice three aspects to obtain.The research indicated that,(1) male female student in the statistical graphs understood the aspect has the common feature The four aspects ranked in a descending order of the percent mean scores are: graph construction, graph reading, graph evaluation and graph interpretation. (2) generally speaking male student is friends with in statistical graphs reading and the explanation compared to the female student, but the female student is better than in the statistical graphs. manufacture the male student.In statistical graphs appraisal male female student not obvious difference.(3) male female student understood in the statistical graphs because in the difference the grade different has the difference slightly.First day the grade female student in statistical chart reading, the manufacture as well as the explanation aspect is lower than the male student, only then in statistical chart appraisal slightly high and male student.Second day the grade female student is lower than the male student well in statistical chart reading and the explanation, the statistical chart manufacture in the male student, in the statistical chart appraisal is higher than the male student slightly.The third day grade, the male female student in the statistical chart understood on the difference reduces obviously.Above research explained that,The junior middle school male, the female student in the statistical graphs understood the aspect has certain difference truly, but the female student is not a weak one who counts the study.If the teacher can give the female student in the teaching process more attention and the encouragement, can the more reasonable arrangement curriculum, certainly be able to reduce or to avoid this kind of difference.
