Conventional mathematics instruction has failed to help many students in urban schools to develop desirable forms of mathematical proficiency. A promising alternative is offered by instruction that is oriented toward helping students develop a meaningful understanding of mathematical ideas through engagement with challenging mathematical tasks. For 5 years, teachers involved in the QUASAR project have engaged in developing and implementing this alternative style of mathematics instruction in urban middle schools. In this article, some critical features of QUASAR instruction are described and exemplified, and some findings regarding the positive impact of this instruction on students are discussed. Finally, some of the challenges and obstacles encountered in attempting to build the capacity of teachers and schools to offer meaning-oriented mathematics instruction are identified.
