Addressing Educational Disparities with Omar Zuniga and Lisa Ceja : Shattering Inequities Podcast Episode 103

Is mathematics the great gatekeeper in education? In this powerful episode of the Shattering Inequities podcast, Dr. Robin Abdelrahman South sits down with stellar educators Omar Zuniga and Lisa to uncover why math is often a bottleneck for student success and what we can do about it.

Through their powerful personal stories and professional experiences, Omar and Lisa reveal the invisible systemic barriers that create achievement gaps. They argue that the solution isn’t just about “fixing” teachers or students, but about fundamentally redesigning the educational systems that hold inequities in place.

Tune in to explore field-tested strategies and the critical importance of setting a clear, high bar for all students, ensuring every child receives the premium education they deserve.

In this episode, you’ll discover:

• The Real Bottleneck: Why mathematics is a critical gatekeeper for high school graduation and college success, especially for historically underserved students.

• Educators' Lived Experiences: The personal journeys of Omar and Lisa, from being the only people of color in their advanced math classes to becoming fierce advocates for equity.

• The Myth of the Even Playing Field: How different textbooks, inconsistent standards, and inequitable grading practices within the same school or district create systemic traps for students.

• Defining the Floor: The urgent need to establish a clear, consistent, and rigorous academic "floor" for every student, in every classroom, to provide a truly equitable education.

• From Belief to Action: Inspiring "not on my watch" stories where educators challenged low expectations and proved that all students can achieve at the highest levels when given the right support and opportunity.

• System-Level Solutions: How focusing on systems—like curriculum alignment, data reflection, and equitable grading policies—is more effective than focusing on individual instruction alone.
