## Fast Facts

There are 125 MTCs in 39 states. We estimate that 2,100 teachers and 400 professors participate, with a potential impact on hundreds of thousands of students each year.

Math Teachers’ Circles are well aligned with the Common Core State Standards for Mathematical Practice and are among only a handful of professional development models recommended by the CBMS MET II report.

This 2015 article in *Perspectives in Urban Education* describes the benefits of MTC participation for teachers as practitioners of mathematics.

An article in the December 2014 *Notices* of the AMS describes MTCs for a mathematician audience.

A substantial benefit of [Math Teachers’ Circles] is that they address the isolation of both teachers and practicing mathematicians: they establish communities of mathematical practice in which teachers and mathematicians can learn about each others’ profession, culture, and work.

Recent research on Math Teachers’ Circles provides evidence about how the program affects participating teachers:

- Teachers develop stronger identities as mathematical thinkers and begin to see themselves as both teachers
*and*mathematicians (Hendrickson, 2016). - Teachers feel more pedagogically prepared and have increased self-efficacy as math teachers. They use more inquiry-based teaching practices in their classrooms (Marle et al., 2012).
- Mathematical knowledge for teaching increases after participating in a Math Teachers’ Circle workshop (White et al., 2013).
- On national surveys with hundreds of respondents, teachers report increased enthusiasm for mathematics; higher levels of professional engagement and leadership; and an increased belief that
*all*their students are capable of doing mathematics (cf. White & Donaldson, 2011).

Benefits for mathematics professors and departments are described in an article from the December 2014 Notices of the American Mathematical Society (Donaldson et al., 2014).

Several Math Teachers’ Circle sessions have also inspired mathematical research, including a publication in Mathematics Magazine by Gene Abrams and Jessica K. Sklar (Abrams & Sklar, 2010), and an article in the College Mathematics Journal co-authored by 13 members of the AIM Math Teachers’ Circle on Sets, Planets, and Comets (Baker et al., 2013).
