Nancy Thaler

Nancy Thaler

Nancy has been an educator since 2001 and has a bachelor's degree in English and a master's degree in education. She was drawn to teaching the unique courses offered at AoPS and the opportunity to work with passionate, engaged students. A-ha moments in the classroom make this work meaningful to her: students demonstrating understanding of a vocabulary word by showing its meaning through physical actions; students delivering a personal monologue reflective of practice in intonation and pacing; students excited to explore the wisdom of Athena or the troublemaking of Dionysus; or reporting on how their experiment is going in anticipation of presenting their science paper. In the classroom, Nancy gently leads a student-centered roomful of kiddos, allowing their voices to be heard, their effort to be nurtured, and their creativity to bloom. She also strongly believes that stickers make every session more fun.

Dr. Ziskind has a PhD in mathematics from UCLA. He taught college for 5 years and then worked in algorithm and software development at Boeing for 33 years. He takes pleasure in sharing the elegance and beauty of mathematics. It is a great feeling when a student perceives the essence of the logic behind some piece of mathematics. Dr. Ziskind proceeds slowly and thoroughly with his presentations and generally takes any opportunities to expand and deepen the basic material. He feels it is important for students to have a feeling for the ideas, not just the mechanics.

Our family regularly talks about AoPS. We try to think about how our life would be different without you all. What if my daughter hadn't learned to love math? What if she never experienced being pushed to her limits? Overcoming failure? She wouldn't be who she is. And she is AWESOME! A very proud mom here. We are so fortunate that we found AoPS Academy. I credit AoPS for much of her confidence.
