## 构造法在中学数学中的应用

Application of Construction Method in Middle School Mathematics
Abstract:Construction method is a way of solving math problems when these problems are difficult to solve with ordinary methods and need to be inspect， analysis and understand with new opinions to catch the internal linkage， use tools and create math model in mind. The way is to use this model to resolve math problems easier and quicker. Firstly， we need to clear basic concept of construction method; then， we need to understand what type of math problems can be solve by construction method in middle school (for instance: number， function， equation， number of columns， complex numbers， geometry， mathematical models， etc.). And to let student understand what aspects they should construct， find a general direction. So that it gives us an area of investigation， makes it easier to analysis and conclude. Finally， it analysis the law and application method of construction method in middle school mathematics.
Key words: Middle School Mathematics; Construction Method; Function; Equation.
