Playing Around with Measures of Center: From Double Dutch to Social Justice

Mark taught mathematics in grades 6-12 in northern California public schools and experienced firsthand the power of creating learning environments in which students – particularly those historically marginalized by inequitable approaches to school mathematics – are supported in making sense of mathematics through collaborative inquiry and culturally relevant lessons.  Since earning a doctorate and becoming a mathematics teacher educator in 2005, he has taught future and current teachers of mathematics in content and methods courses at the undergraduate and graduate levels and has published over 40 articles and two books including Reimagining the Mathematics Classroom: Creating and Sustaining Productive Learning Environments, K-6. All his work is driven by a belief that every student has the potential to be successful in learning mathematics and a commitment to ensuring this potential is fulfilled in every classroom.
