| Abstract: | Algebraic expressions are very important contents in j unior mathematics curriculum. At the same time they are also the boring part in the past. Unlike the traditional way that algebraic expressions mainly deal wit h the operations, the New Century Version Textbooks emphasis the function of rep resentation, emphasis the connection between algebraic expressions and real worl d problems, and emphasis the students' understanding. For the operations the tex tbooks lower the degree of difficulties on one hand, and on the other hand the t extbooks emphasis the meaning of the operations. |
