The world we have come to know through the mathematical sciences comprises one ground within which new technologies are formed and changed. Society, which constitutes the settings within which mathematics and technology develop and work, is limited by them. Hence student potential may be freed by improved technology, but is also constrained by it. Foundational mathematics instruction should develop an appreciation of the role of reckoning within other disciplines, as well as build basic arithmetic theoretical content and procedural knowledge. Instruction should provide students with interesting and sufficient exposure to the rich body of fundamental mathematics that underlies various subject areas, and guide students to an appreciation of the intellectual depth and the abstract issues that will challenge them in their future collegiate studies.

Currently the Head of the Foundational Mathematics Department in the Division of Mathematics, Science and Health Careers at CCP, I have worked in the field of Higher Education for over 30 years, having taught undergraduate and graduate mathematics and computer science courses in colleges and universities across the country. Also I have served as a Mathematics and Computer Science department chairperson as well as supervised various mathematical sciences programs. My educational background includes a Doctor of Education with emphasis on the College Teaching of Mathematics from Columbia University in the City of New York. A Chicago native, I have a Bachelor of Science and a Master of Arts in Mathematics from Loyola University of Chicago.

Eric Neumann

Have you become convinced that math just doesn't make sense? Fret not: Professor Neumann can and will help you understand why math works the way it does. There are no non-math people. With just a little diligence, an open mind, and the right guidance, everyone can understand math.

Prof. Eric Neumann is an Assistant Professor in the Foundational Mathematics Department of Community College of Philadelphia. He joined CCP in 2012, and was granted tenure in 2016. He grew up in the suburbs of Chicago, earned his BA in Mathematics with a Psychology minor at Colby College in central Maine, and, while teaching at a small Christian high school in Camden, NJ, earned his MS in mathematics at Rutgers University-Camden.

He has taught or tutored all levels of mathematics from pre-K through calculus, and enjoyed the unique challenges of every level -- but he particularly loves studying the logical foundations of arithmetic and algebra, and articulating those big ideas in clear, relatable ways. Professor Neumann loves Jesus, his wife, his four kids, and the city of Philadelphia (in that order), and enjoys learning about natural movement, economic theory, and the diversity of human experience. He is passionate about finding new and better ways to foster deep and lasting mathematical understanding, and tries to live by two mottos: "Never stop learning," and "Soli Deo Gloria."

You might see Eric walking or cycling between CCP and his South Philly row home. If you do, please wave "hello," and try not to run him over.

Thierry Elin-Saintine, Ph.D.

I hold a Ph.D. in urban education from Temple University, a Master’s of Arts (M.A.) in Math Education and a Master’s of Fine Arts (M.F.A) in creative writing and literature from the City College of New York. My background in creative writing, the performing arts, and mathematics education have provided me the confidence and flexibility to embrace and favor the student-centered, social-justice oriented and cooperative learning environment where student engagement and critical thinking are central and always sought after.

For most of my teaching career, I have worked with students whose learning styles and accumulated negative mathematical experiences made it difficult for them to succeed in traditional mathematics classrooms. Thus, I have always been challenged and continue to revise and refine my pedagogical and instructional methods in order to produce lessons, activities and assessment tools that allow multiple points of access for different learners while engaging every student meaningfully. Mathematics is the perfect vehicle for problem-solving and critical thinking; my objective, regardless of students’ mathematical aptitude and interest level, is to foster students’ creative abilities and provide them with the tools needed to experience mathematics as it is intended.

In my view, the classroom represents a space and ongoing opportunities for students to deepen their understanding of the world, develop a more nuanced and sophisticated view of their lifeworlds (their lives outside the classroom), and to begin the process of imagining themselves as transformative agents committed to the fight for a more equitable tomorrow. I am convinced that mathematics classrooms are the ideal sites for this transformation.

Yusefa Smith, instructor of foundational mathematics, received her M.S. in mathematics from Rutgers University and B.S. in mechanical and aerospace engineering from Princeton University. Prior to Community College of Philadelphia, she was a high school math teacher in Cherry Hill Public Schools in NJ. Her teaching philosophy is that effort creates ability and so she strives to be a great motivator to her students to get their best effort. Her track coach often stated after a hard workout that it was “money in the bank.” Every workout was a small deposit towards achieving a personal goal. She uses the same idea in education. Every class, every homework assignment, every effort is “money in the bank.” Students bring the effort and she’ll provide the proper coaching.

She is currently the chair of the accelerated courses that are offered in the department in addition to serving in other committees in the department.

She has a great passion to help students that have a dis-like/phobia of mathematics. It is her desire to have students earn an adoration and understanding of mathematics in everyday real-life aspect. She is enthusiastic in helping all students excel through foundational levels of mathematics and enter academic degrees pursuing career that greatly uses and enforce the science and applications of mathematics, especially STEM. She is interested in research that focus on exploring methods for developing students’ understanding while they are taking lower-level mathematics courses to promote their engagement in advanced mathematics.
