Education Research Of Primary Integer Division

This study originated in practice requires. Although the domestic scholars pay close attention to the integer division, it has not formed any integer division books of the elementary school. This study lasted half a year, by using the interview method and literature method as the main research methods, with the integer division teaching in primary schools, as well as an inquiry of the integration of existing research. Not only with a referenced significance, besides, it provides guidance for teaching practice. This is the significance of the research.Primary integer division is distributed among the materials in book2of grade2to book1of grade4. It contains the "division in the table","division in the table II","the division with remainder","divisor is a digit division" and "divisor is double-digit division". Teaching materials based on curriculum, curriculum came up with more clear requirements to the integer division teaching in primary schools than teaching materials, in the curriculum design, goal setting and teaching content.Most of the scholars and teachers think that the meaning of the average is gained from operation. Teachers lead to the "division algorithm in the table" by the "average derivation" while teaching the "division in the table", they could also use the "definition of average" parse "contains division" is average. But for "why using the multiplication division" solving the problems, it needs to resolve with the help of the multiplication and subtraction as a bridge. However, with the necessity of using vertical is not possible to understand by the experience formula for students, vertical writing forms were gained from the exploring merit. It has been a long time on the research of the remainder for the scholars."0" is a remainder, but it is not appropriate to teach that concept in this learning phase. In teaching progress, this permeability principle "divisor is a digit" is the most important and remarkable teaching requirement. The study concluded that using two methods which are teaching aids and blackboard writing auxiliary students to understand and study. This content arrangement "divisor is double-digit division" is similar with the knowledge of the last one, so by using old knowledge comparing to promote knowledge transfer is a common strategy.
