GSDMC Executive Board
Jason Slowbe, President
I have taught high school math since 2004 – my first 3 years were in Cleveland, OH, then I moved to Southern California and taught at Escondido High School, San Marcos High School, and currently at Great Oak High School. Whether it's professional development, curricular revisions, or my wicked addictions to GeoGebra, Excel, and programming, my passion is teaching high school mathematics. I have worked with NCTM in various roles, including Illuminations, the Reasoning and Sense Making Task Library, Regional and Annual program committees, and as a task group leader for NCTM’s High School Summer Institutes. I work with the CMC-S Conference Committee for their Palm Springs conference. With GSDMC, I have been the Secretary and also Webmaster since 2010, and now welcome the opportunity to lead GSDMC forward as President.
Mindy Shacklett, VP Programs
Mindy Shacklett is San Diego County Office of Education (SDCOE) Mathematics Coordinator. Her previous work at three Fortune 500 companies provides irrefutable support for her claim that "math cannot exist in isolation..ever." After having taught various math courses in San Diego high schools, she now supports mathematics teaching in the county's forty-three districts, focusing on providing professional development for administrators and teachers in support of implementing the Common Core State Standards for Mathematics.
Chris Bonta, VP Membership
I am currently the AP Stats teacher and Algebra 1 lead at Carlsbad High School. I am also a football coach and the Senior class advisor. I spent this past summer on a team responsible for aligning our Algebra curriculum with the new Common Core Standards. I have been working in education for the past 14 years as a teacher, tutor, and coach. Some highlights in my career have been working with Upward Bound and serving as an instructor at Mira Costa College in their adult education program helping adults complete their high school diploma. I have been very lucky to have the experiences of working at a private school, a charter school, two public high schools, and two colleges. I am expecting to graduate in March from National University with a Masters in Educational Leadership and will also receive my administrative credential.
Sean Nank, Secretary
The GSDMC brings resources to students, parents, and educators in our local communities that are essential for connections, collaboration, and the betterment of mathematics education. We stand on a precipice of change with our transition to Common Core. This transition makes GSDMC more important than ever before. I look forward to the opportunity as secretary to bring my experiences and resources to our wonderful organization. I will use my experience as a Presidential Awards for Excellence in Mathematics and Science Teaching (PAEMST) recipient, author, researcher, consultant, and ICME-12 appointed mathematics assessment expert to continue the great work at the GSDMC.
