Training undergraduates to prepare for careers in mathematics teaching and teacher leadership

Developing mathematics curriculum and assessments that engage students in creative reasoning and meaningful application of mathematics.
Our Team
Heather Dallas
Executive Director
Heather Dallas has taught mathematics for almost 30 years in local public schools and the UCLA Mathematics Department. As a public school teacher, Heather codeveloped 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 almost 20 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 201517 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. Heather’s father was the first LAUSD mathematics teacher to bring computers into the classroom in 1978 and her grandfather was a high school English teacher.
Michelle Sidwell
Assistant Director
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 80hour inquirybased 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 20152017 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.
Michelle Welford
Director of 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 CoDirector of the 20152017 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.

In the Department, Helen taught mathematics courses for future elementary school teachers and mathematics courses for current elementary school teachers and coauthored a number of mathematics courses for current teachers.
Helen has authored Smarter Balanced Performance Tasks for use on summative statewide assessments across more than 21 US States. Currently, she leads the Center’s professional development team.
Eden Murphy
Director of 9th12th Professional Development
Eden Murphy holds a Master of Arts in Education, a Bachelor of Arts in Mathematics. Her practitioner experience includes ten years of mathematics teaching and coaching in the Apple Valley Unified School District, during which time she worked to create an equitable and accessible pathway to Calculus, while also becoming a leader in instruction that centers around student inquiry of mathematics by means of modeling and proof. Currently, Eden provides mathematical and pedagogical training to mathematics teachers across California, in addition to authoring mathematics performance tasks as part of the Center’s partnership with the Smarter Balanced Assessment Consortium. Eden has particular expertise around best practices for online instruction as well as appropriate use of educational technologies in the mathematics classroom.
Julian Rojas
Secondary Mathematics Specialist
Julian Rojas holds a Master of Arts in Education and a Bachelor of Science in Mathematics for Teaching from UCLA. He has seven years of practitioner experience teaching mathematics, engineering and computer science in public and private schools in Los Angeles. He has taught at both the middle and high school levels.

Our History
The UCLA Curtis Center is involved in a variety of activities that benefit from the intersection of university and K12 mathematics expertise. This activity is the continuation of decades of departmental involvement in the entire spectrum of mathematical activity, from K12 to university to career. The department’s involvement at the precollegiate level was significantly shaped by Professor Emeritus Phil Curtis over a fiftyyear period. While producing pioneering and internationally recognized work in the Banach Algebra, Professor Curtis served twice as Department Chair and advocated for departmental involvement in K12 mathematics activity. Over his many years of service, he worked to establish six programs supporting K12 mathematics activity including the statewide UC/CSU California Mathematics Diagnostic Testing Project, the UCLA Visiting High School Teacher Program and the UCLA Joint Mathematics Education Program, the UCLA Mathematics Project, the UCLA Math Content Program for Teachers, and a program which prepared K12 students for competitive mathematics exams.
Building upon Professor Curtis’ tradition, at the impetus of Chair Christoph Theile and Professor Theodore Gamelin, the UCLA Math Department established the Philip C. Curtis Jr. Center for Mathematics and Teaching on June 5, 2007 and appointed Professor Curtis as its first Faculty Advisor and Heather Dallas as its Executive Director.
Professor Phil Curtis passed on December 19, 2016, and we miss him dearly.
Mathematicians and Teachers Working Together
Professor Phil Curtis recognized that no one person has the totality of expertise required to effect meaningful, highimpact positive change in America’s K12 mathematics activity. In each of his programs, he intentionally developed nonhierarchical collaborative communities of K12 and university mathematics faculty. This respectful ethos was the fertile soil that grew the Department’s current K12 mathematics activity and is now the sunlight to which it leans.
Curtis Center efforts are still regularly effected by teams of K12 and university mathematics faculty. Whether authoring new K12 or continuing education curriculum, assessments, and courses of study, university mathematics faculty often benefit a collaboration by enhancing mathematical precision, highlighting the mathematical horizon, and/or suggesting mathematically interesting questions. K12 mathematics faculty benefit collaborations by focusing the work on mathematical issues most relevant to K12 mathematics departments and providing professional knowledge of language, pedagogy, and sequencing appropriate to the K12 classroom as well as an understanding of student’s common errors and interests.
