Students often believe that mathematics does not belong to them; that mathematical content belongs solely to those who teach it, and that their mathematical voices are not important. Students do not see themselves as thinkers and holders of rich mathematical knowledge. At the heart of my research is empowering students to see themselves as creators and doers of mathematics. For this to happen, we need to develop learning contexts in which students are encouraged to explore and debate mathematical ideas. During my lecture, I will share findings, stories, and ideas from my research and teaching practice that I believe can assist all learners to find their mathematical voice and become deep, insightful thinkers of mathematics.
