students’ performance on open-ended problem solving tasks and their NAEP scores. Other
studies also indicate that curricula that emphasize complex mathematical tasks are indeed
beneficial for all students (Boaler, 2002b; Schoenfeld, 2002; Tarr et. al, 2008).
Another aspect of curricula that support diverse learners is grounding mathematical ideas
in contexts familiar to students (Boaler, 2008 Davis, West, et. al., 2007). Such contexts help
students leverage their everyday, out-of-school experiences for in-school learning, and motivate
students by communicating the power of mathematics in their worlds. In her seminal study
involving two schools attempting to implement reform-based instruction, Boaler (2008) found
greater gains in a school in which the mathematical tasks were closely tied to experiences in the
students’ lives. Similarly, one of the central tenets of the Algebra Project (Davis, et al., 2007)
curriculum is engaging students in shared experiences that serve to bring them into the language
and culture of mathematics. Their work shows that such experiences help students to connect
their own ways of reasoning and explaining to the formal structures of mathematical discourse.
Likewise, the teachers at Railside devoted considerable time and energy to developing
and enacting a curriculum that challenged students to engage with complex mathematical ideas.
They worked together to plan activities and lessons that they called “group-worthy” -- employing
mathematical tasks that foster deep engagement with challenging mathematical problems and
rich mathematical discussions among students. They continually revised these lessons together,
sharing ideas and strategies for optimal implementation, as well as analyzing failures and
potential pitfalls. Over the course of several years, each teacher had compiled a large binder with
these co-written and revised activities, which they used as the basis for their activities in the
classroom.

Classroom Practices that Support Equity
Equally important to the content of the curriculum are classroom practices that enable
students to engage with the curriculum and create mathematical meaning from it. Powerful
practices include those that foster student-centered discourse, student exploration of
mathematical ideas, and on-going feedback (Davis, et. al., 2007; Boaler, 2002b; Fullilove &
Treisman, 1990). Studies indicate that supporting students in working productively in small
groups to discuss their understanding and provide help to their peers leads to increased
performance (Webb & Farivar, 1994; Boaler & Staples, 2008; Silver & Stein, 1996; Fullilove &
Treisman,1990).
Researchers stress the importance of the role of teachers in fostering and facilitating
productive student discourse as well as the importance of “group-worthy” tasks (Cohen & Lotan,
1997; Boaler & Staples, 2008). Changing participation structures from lecture or teacher-
centered discourse to student-centered discourse may result in discomfort for some students and,
if not sufficiently supported, can lead to a lack of positive results (Lubienski, 2000). However, as
Webb and Farivar (1994) demonstrated with sixth-grade students, supporting students in learning
how to talk with and help each other and providing sufficient feedback on individual work
results in significant gains for Black and Latina/o students.
Issues of unequal status in classrooms can create inequitable learning in the context of
group work (Cohen & Lotan, 1997). Cohen and Lotan (1997) have identified two practices that
can address issues of differential status: broadening the meaning of “smart” by reorganizing
curriculum and instruction around multiple ways of representing and interpreting mathematics,
and assigning competence to low-status students by publicly recognizing these students’
mathematical ideas and contributions. Boaler and Staples (2008) studied the effects of these
18
classroom practices in mathematics classrooms at Railside High School, documenting their
positive effects on both mathematics achievement and the development of positive mathematical
identities. They found that the teachers at Railside regularly assigned competence to students
who did not see themselves as “smart” in mathematics, and found ways to support those students
in finding new ways to be smart, for instance, by asking productive questions. Railside teachers
also developed shared ways of supporting students to talk mathematically and to work together
on complex tasks. They found that giving students more challenging material was a critical
aspect of supporting higher levels of achievement.
Connecting to Students’ Cultural and Real-World Experiences
In addition to high-quality curriculum and classroom practices that support equity, an
important component of creating a classroom context that best supports the learning of students
from historically marginalized groups is connecting to students’ cultural or real-world
experiences. Learning is an inherently cultural endeavor (C. Lee, 2007; Nasir, 2011). The
research literature in mathematics education identifies two potential ways that math classrooms
can connect to students’ cultural worlds. The first is through activities that are “culturally
congruent,” that is, activities and content that draw on students’ knowledge base and experiences
outside of school. For instance, Gonzalez, Moll, and Amanti (2005) design classroom activities
that build on expertise in Latina/o students’ homes and communities. They incorporate families
and community members into the life of the classroom, and encourage teachers to connect with
families to better understand and utilize the cultural funds of knowledge of students and their
communities. Similarly, Civil (2007) and Moses & Cobb (2000) have designed mathematics
lessons that build on the cultural knowledge of students and families, for instance by creating
