Culture + Pedagogy + Mathematics: Multiple Perspectives in a Latino Community
In this presentation I focus on the influence of a teacher and her teaching practice, with a vision of social
justice, on Latina/o students’ learning of mathematics. This study builds on current understandings in the
area of mathematics education, as well as on Latina/o students’ academic opportunities. It draws on a multi-
level framework to explore Latina/o students’ mathematical learning from a socio-historical perspective
(Martin, 2000). The teacher’s, students’, and parents’ perspectives are included throughout the process of
inquiry. This study is based on the premise that learning is goal-oriented and identity is an integral
component of learning in connection to the community. A collaborative environment is central to supporting
students’ identities as mathematics learners and critical mathematics citizens. Students’ participation in the
classroom community needs to include interconnections with their lived-culture (Gutierrez & Rogoff, 2003;
Moll, 2000) and a critical lens embracing diversity as a resource. These connections support students’ sense
of ownership in the negotiation of mathematical meanings. Finally, through the in-depth case studies I
identify those cultural beliefs that might have an oppressive effect on students and their communities
(Martin, 2006), but also those that resist and counter deficit views that society bestows upon them.

Toward a Definition of Literacy: Implications for Mathematics Classrooms and Teacher Education
A singular, agreed-upon definition of literacy does not exist. Indeed, there are compelling arguments for
maintaining flexible definitions of literacy that continue to evolve over time. We will explore various
definitions of literacy-particularly those that embrace a broad notion of text-and consider their usefulness for
making sense of mathematical participation. Indeed, when creating diagrams, manipulating symbols, and
explaining solutions to problems are viewed as literacies necessary for reasoning, learning, and
communicating mathematics, literacy instruction must be viewed as a requisite component of mathematics
instruction. Implications for the preparation of teachers will be discussed.

Modeling and Probing Practical Rationality in the Teaching of Algebra:
Animations and Teachers' Talk About Them
When justification, reasoning, and proof appear in the secondary curriculum, why do they tend to appear in
geometry classes, and not in the algebra classes that the same students take? More particularly with respect
to algebra, why does the secondary curriculum, in both reform and traditional variants, seem to resist the
inclusion of justification, reasoning, and proof? Why are so many of the methods taught in algebra left
unjustified? As a window into such questions, in this talk, I will outline the rationality of mathematics teaching
(Herbst & Chazan, 2003) as an object of study in mathematics education. This construct is based in a view of
teaching as a social activity that occurs in a particular kind of societal institution with its own kind of
"economy." Thought experiments in mathematics teaching (ThEMaT) is a research project that has explored
this rationality by building models of situations in mathematics teaching, like the doing of algebra word
problems and the solving of equations, and then testing hypotheses derived from these models. These
hypotheses were tested through data collected from teacher study groups convened around animations of
high school classroom practice. This process will be illustrated around claims about the nature of instruction in
algebra word problems in the US.

Rethinking Change
We'll consider a sequence of concrete case examples, anchored to a single image (of a fossil shell) to explore
the complexity of building mathematical models in compelling realistic situations. The case examples draw on
work with calculus undergraduates and dance majors from an experimental mathematics course. In the
course of extended conversations and collaborations with students over several years, we'll sketch evolving
thinking about how learners, thinking mathematically and physically about change and motion, made sense
of real-world situations.
