# About Us

The UCLA Curtis Center is a group of K-12 and university mathematics enthusiasts who work together to improve the quality of K-12 mathematics activity.

The UCLA Curtis Center is a group of K-12 and university mathematics enthusiasts who work together to improve the quality of K-12 mathematics activity.

- Provide effective opportunities for K-12 teachers to deepen their understanding of the mathematics they teach, extend their knowledge of mathematics, and learn how to apply their mathematical knowledge to the work of teaching.
- Provide effective training of undergraduates for careers in mathematics teaching and mathematics teacher leadership.
- Write mathematics curriculum for use in K-12 mathematics classrooms that engages students in sense making, justification and application of mathematics.
- Develop mathematics assessments focused on problem sovling, communicating reasoning, and application of mathematics in order to promote student readiness for college mathematics courses, careers and life.
- Provide high quality mathematics activities for students in local schools to give them a view of mathematics as a creative reasoning and problem solving activity with intrinsic beauty and meaningful application.

The UCLA Mathematics Department has a strong tradition of involvement in the entire spectrum of mathematical activity with programs ranging from K-12 mathematics to advanced current research. The department’s involvement in mathematical activity at the pre-collegiate level was significantly shaped by Professor Emeritus Phil Curtis, who played a singular role in the establishment of most of the department’s current mathematics education programs.

Building on this tradition, on June 5, 2007, the department, at the impetus of Chair Christoph Theile and Professor Theodore Gamelin, established the Philip C. Curtis Jr. Center for Mathematics and Teaching, to further high quality K-12 mathematics activity.

Philip C. Curtis Jr. was a UCLA Mathematics professor for over 50 years and produced pioneering and internationally recognized work in the Banach Algebras. He was appointed as Chair of the UCLA Mathematics Department two times and was a leading advocate for high quality K-12 mathematics instruction.

Over his years in the UCLA Mathematics Department, Phil founded the statewide UC/CSU California Mathematics Diagnostic Testing Project, the UCLA Visiting High School Teacher Program, and the UCLA Joint Mathematics Education Program. He was instrumental in the development of the UCLA Mathematics Project, the UCLA Math Content Program for Teachers, and a program which prepared K-12 students for competitive mathematics exams. He passed on December 19, 2016.

Heather Dallas

Executive Director

Heather Dallas has taught mathematics for 25 years in local public schools and the UCLA Mathematics Department. As a public school teacher, Heather co-developed a specialized course for students previously excluded from Algebra in which failure rates were cut in half. In addition, she increased student access to success in BC AP Calculus, increasing enrollments sevenfold while maintaining an almost 100% pass rate. During this time, she taught and developed curriculum for the professional development efforts of both the California Math Project and the UCLA Mathematics Department. In 2000, she served as the UCLA Mathematics Department’s youngest ever Department Visiting High School Teacher and since then she has trained 17 cohorts of senior mathematics majors to be secondary mathematics teachers in her role as lecturer in the Department.

In her role as Director of The Curtis Center, Heather has led multiple projects with districts and industry partners aimed at improving the quality of mathematics activity in schools. She served as PI on two California Math Science Partnership grants and directed the 2015-17 Smarter Balanced Performance Task Development Project. In addition, she regularly provides national and statewide leadership in mathematics education, and has served on the California Academic Content Standards Committee, the U.S. Dept. of Education’s Race to the Top Technical Review, and the California Framework Committee. She is also a Nationally Board Certified Teacher.

Michelle Sidwell

Director of Special Projects

Michelle Sidwell earned a B.S. in Mathematics/Economics and a Masters of Education during her time at UCLA. During this time, she also engaged in mathematical research in the prestigious RIPS program at the UCLA Institute for Pure and Applied Mathematics. Upon graduation, Michelle taught mathematics at Crenshaw High School for six years. In this role, Michelle developed much of her own curriculum and significantly expanded student access to and success in AP Calculus and AP Statistics.

At The Curtis Center, Michelle has taught mathematics courses and professional development institutes for current teachers and authored curriculum for the mathematical training of teachers, including an 80-hour inquiry-based Geometry course. She served on the Project Leadership of BRIDGES, a California Math Science Partnership with Glendale Unified School District. In addition, she served as the High School Grade Band Leader for the 2015-2017 Smarter Balanced Performance Task Project, authoring and editing assessment items for use in summative statewide assessments used across 21 US States. Recently, she oversaw the development of 13 Geometry lessons which benefited from the use of magnetic polygonal tools, called Magformers, as concrete models.

Helen Chan

Director of Professional Development

Helen Chan earned a B.S. in Mathematics/Applied Science, a California Teaching Credential, and a Master of Education from UCLA. She has 23 years of experience in K-16 mathematics education, including 11 years with the UCLA Mathematics Department. In the Department, Helen taught mathematics courses for future elementary school teachers and mathematics courses for current elementary school teachers and co-authored a number of mathematics courses for current teachers.

Helen served as an author for the 2015-2017 Smarter Balanced Performance Task Project, writing a number of elementary mathematics performance tasks for use on summative statewide assessments across more than 21 US States. Currently, she writes mathematics curriculum and trains instructors for the Center’s professional development work with local mathematics teachers.

In addition to her work at The Curtis Center, Helen currently also teaches algebra at Da Vinci Innovation Academy.

Michelle Welford

Director of Formative Assessment

Michelle Welford holds a Bachelor’s degree in Mathematics, a Master’s in Education and is a Nationally Board Certified Teacher. She taught high school mathematics for 10 years during which time she wrote her own Geometry and AP Statistics curriculum. Her efforts significantly improved student access to success on the AP Statistics exam, with pass rates increasing from 20% to 94% after she took over the program. Michelle followed these successes by serving for five years as an instructional coach at University High School for the Los Angeles Unified School District during which time she also wrote professional development curriculum in geometry for the UCLA Mathematics Department.

Michelle’s work for The UCLA Curtis Center, draws on her extensive knowledge of mathematics, pedagogy, Common Core State Standards, incorporation of technology, teamwork/collaboration with others, meticulous attention to detail, and time management. Michelle Welford was Co-Director of the 2015-2017 Smarter Balanced Performance Task Project during which time she was pivotal in the development of 168 mathematical modeling tasks used in summative assessments across 21 US States.
