Abstract


The score is an important content of elementary school mathematics teaching . Fraction concept is a huge system , students ' understanding of the fraction concept is not easy , fraction concepts are interrelated , and a chain of average , division , decimals, about points , common denominator , ratios , percentages , etc. together constitute the tight score conceptual system . Teaching today , students' scores grasp of the concept system what are the problems it ? Select few primary test , aimed at understanding the students grasp the situation and to identify the student's score in the concept of learning about the fraction of concept system exists understand some of the problems : ① student scores meaning relatively simple. ② The student did not really establish the fractional concept system , the structure is relatively loose concept in their minds , most of the various concepts in the isolated state . ③ student understanding of the relationship between scores and percentages , division ratio problems . Under the guidance of the three questions , through the analysis and teaching of the Su Jiaoban textbooks , found many debatable textbooks in the the fraction concept architecture arrangements and the specific content of the presentation , such as the fraction of the structure of the conceptual system can arrangements closer , teaching materials should improve the structure of the fractional - concept system ; introduce the significance of scores from different angles ; than to reveal the essential attribute . Teachers in Score teaching to enrich students' conceptual representation system ; attention to the links between the various concepts , to help students develop a concept network , the fractional concept is part of the teaching system more perfect .
