[Abstract]:According to Piaget's theory of cognitive development, the score has the meanings of "number of copies", "quotient", "measurement", "arithmetic" and "ratio". The above five different meanings correspond to the cognitive characteristics of students of different ages. However, in the teaching materials (take the teaching version of people as an example), the different meanings of scores are reflected according to the grade. In the teaching of scores, the meaning of "number of copies" is emphasized to help students understand the scores. We should also pay attention to the students' deep understanding of the meanings of the five different levels of scores. Only by understanding the different meanings of scores can we really understand the essence of scores and master all kinds of complex operations of fractions.
