Research Of Math Graphic Representation In Junior High School

Based on the reference to the research on math graphic representation, this paper summarized the developing of math graphic representation in junior high school and proposed the problems and difficulties of math graphic representation in junior high school in China at present. By the investigation and interview, we designed the math graphic representation in junior high school questionnaire can be used to investigate student's development of math representation with Chinese culture. It is good foundation for math graphic representation with reification and maneuverability. On the basis of math graphic representation in junior high school I give some recommendations on math teaching.The whole study is composed of four parts:â… . The problems and difficulties of math graphic representation in junior high school in China at present are: (1)The definition of math representation and math graphic representation are still ambiguity; (2)There is no sufficient practical research to support math graphic representation teaching; (3)There is no math graphic representation in junior high school questionnaire can be used with Chinese culture; (4)The validity of cultivating method's in math graphic representation is not to validate.â…¡. The math graphic representation in junior high school questionnaire with Chinese culture is developed and analyzed. The results indicated that:The math graphic representation in junior high school questionnaire has good homogeneity reliability and criterion related validity. So the development of math graphic representation in junior high school questionnaire has the good reliability and validity. It will become the math graphic representation in junior high school quantitative study measurement.â…¢. We investigated math graphic representation in junior high school. Result show that: 1, The correlation between grade, age and math graphic representation: (1)The correlation between age and math graphic representation is significant; (2)The correlation between year and math graphic representation show that: the means between grade one and grade two is significant; there is no obvious correlation between grade two and grade three; there is also no obvious correlation between grade one and grade three; (3)Boys and girls have no difference in math graphic representation; (4)There is no among sex, age and math graphic representation; (5)There is no obvious correlation among sex, grade and math graphic representation; 2, The correlation between math achievement and math graphic representation is significant. 3, Subjective analysis show that: (1) As learning common sense, students have age characteristics in learning math knowledge and that younger students rely on more graphic representation is obvious. (2) The higher-grade students has higher correct answer rate in overall math problem.â…£. Some recommendations on math graphical representation: (1)Using a variety of sensory perception to rich math graphic representation; (2) Giving association and imagination on basis of math graphic representation; (3) Promoting the harmonious of shape and number to develop mathematical thinking; (4) Constructing space concepts to develop math graphic representation.The innovative works include:1. Proposed the problems and difficulties of math graphic representation in junior high school in China at present.2. Developed the math graphic representation in junior high school questionnaire can be used to investigate students' math graphic representation with Chinese culture and has analyzed with quantities method.3. Investigated the math graphic representation in junior high school first time.
