5-7 Grade Students With The Number Of Letters Understanding Level Of Investigation And Study

Compulsory education teaching emphasis on helping students’ build number sense and symbolic sense, the consciousness of "symbol" is the number of letters. Students level of understanding of the number of letters to the students from arithmetic to fast learning algebra, also laid the groundwork for future learning algebra, so to let students establish algebraic thinking is to make students grasp the content of the letter number contained. This article focuses on the research of 5 to 7 grade students in the number of letters of the problems existing in the learning process and the impact of external factors on its.This article focuses on the research of 5 to 7 grade students in the number of letters of the problems existing in the learning process and the impact of external factors on its.In the whole course of the investigation, the author of 5 to 410 students in grade seven in letters several aspects has carried on the questionnaire, six teachers and 12 students for the interview, according to the division SOLO understanding level, finally draw the conclusion:Nowadays most of students’ thinking there is a big problem of abstract algebra, in terms of number of letters, more than five grade students in a single structure level, grade 6 students in a more diverse level of structure, and only a few can achieve grade, seven related structure level.There are many factors that can cause this situation, the author through interview and questionnaire is summarized, and the students’ mathematics reading ability is weak, and in two period of convergence problems. Finally the author puts forward several opinions for the above two aspects.
