Society is moving from an industrial age into an information age. It is these needs. . Many important problems require making sense of large amounts of information with the help of technological resources. A great deal has been learned recently about how students learn mathematics and develop mathematical autonomy. If students are to become good problem solvers, they need extensive opportunities solving challenging problems.
Students are sense-makers.
If given the opportunity, they are capable of developing creative and useful strategies. Many routine skills that have dominated classroom practices of the past can be acquired, when they are needed, in the context of solving problems. Students' attitudes and dispositions toward mathematics are strongly influenced by classroom experiences, the home, and the community. Confidence, eagerness, persistence and other valued dispositions develop while doing interesting and important mathematics. All students are capable of doing mathematics.
