This is an exciting time to be a mathematics teacher-educator.

In the past two decades, we have developed a much better understanding not only of how children learn math, but also of how to teach math - and how to prepare teachers to teach math. A short (though incomplete) list of teaching practices that we know work to support student learning includes posing challenging tasks that connect to children’s prior understandings and out-of-school experiences, providing opportunities for children to make sense of and talk about mathematics, and promoting the use of mental mathematics based on patterns in our number system.

Yet it is also a challenging time to be a mathematics teacher educator because these teaching practices are not being used in most classrooms and schools. Further, there are many constraints limiting the use of these practices - ranging from high-stakes testing to crumbling schools.

Here, I am advocating for an approach to mathematics teacher preparation that takes seriously our responsibility to support novice teachers in making small changes in the status quo of mathematics teaching while working together with teachers to create more transformational changes.

At the level of the individual teacher, we have found that preparing teachers to make small changes in status quo practices and tools can be a successful approach that is both manageable for teachers and meaningful for their students. In my work with novice teachers, the small changes I emphasize most include:

1. Ask students “why” at least once every day. Why did that strategy work? Why does that strategy make sense? Why would this work for all numbers?
2. Instead of looking only for whether a student’s answer was right or wrong, focus on what was right in the student’s work. Then build on what the student did understand in your next discussion and next task.
3. Use your textbook as a tool. Find meaningful tasks in the materials - or tasks that could be meaningful and accessible for students with small changes in numbers or contexts.
4. Provide at least one opportunity each day for students to solve and explain problems mentally (without pencils, paper, calculators, or computers). This promotes students’ sensemaking, creativity and, most importantly, their sense that they are mathematicians.

At the heart of all of these changes is the idea that children learn best when they have opportunities to explore and make sense of mathematics and when teachers have opportunities to hear and respond to children’s ideas.

While these kinds of small changes can help teachers develop their teaching practices and can lead to increased learning for their students, classroom-level changes will ultimately only lead to, at best, incremental change in the status quo of the larger systems of mathematics education in the United States. However, expecting teachers to have the sole burden for changing these systems is not only ineffective, but also ethically problematic.

Thus, as teacher educators, we must also work together with teacher candidates and teachers to advocate for systematic changes in systems that continue to perpetuate oppression in mathematics education, that allow for the same groups of students to be denied opportunities to learn rigorous mathematics year after year, and that are silent in the face of crumbling and unhealthy school buildings.

To this end, teacher educators and teacher preparation programs must engage together with prospective and practicing teachers in work that: values advocacy skills and a sense of agency as important aspects of teaching; insures all students have access to relevant high-level curriculum; utilizes assessments that reflect the content and practices that we want all students to know and be able to do and supports students in reaching those goals; and understands schools are just one part of communities and that schools and students cannot be healthy unless and until their communities are healthy.

I began this article noting that this is both a challenging and exciting time to be preparing teachers to teach mathematics. The challenge is that the goal of providing meaningful and equitable mathematic education to all students has been a persistent, yet elusive, goal in the United States for many decades.

The excitement comes from the knowledge that we know what to do - in both K-12 and higher education - to prepare teachers to teach mathematics in meaningful and equitable ways. It should go without saying that the kinds of work described above require teachers who know their mathematics content well. However, the best mathematics teachers will be the ones who have been prepared to empower their students as mathematicians and to teach students that mathematics makes sense.

We know how to do this, but we need to be willing to work together across all of our communities to make the kinds of instructional practices and systemic changes described above accessible to every teacher and every student in the United States.
