摘要：AbstractGraphs as representational tools are very important in all disciplines especially in mathematics. They are useful for summari zing sets of data, obtaining and interpreting new information from complex data. The purpose of this study is to investigate pre-service mathematics teacher's graphing skills. The participants are 32 pre-service mathematics teachers from a public university. Graphing tasks and questions corresponding to the interpreting, modeling and transforming components of the graphing skill (Kwon, 2002) were used in gathering written data and interviews conducted with selected participants. It is concluded that students have problems in modeling and transforming tasks but they can extract information from graphs so they are better in interpreting tasks.
