Math & Science

Elizabeth Sczesnak

Elizabeth Sczesnak is the new BIS Science teacher. She has an MAT in Biology from Queens College, and a BSc in Biology with a minor in English Literature from McGill University in Montreal, Quebec. She previously taught Middle School in the Bronx and worked as an educator at Queens Country Farm. Elizabeth has volunteered on organic farms across the country, and she is also a twin! She enjoys helping students see that science is a part of their everyday lives, and integrates writing into her practice. She feels fortunate to be a teacher because she learns from her students every day.


David Schroeder

DSDavid Schroeder has been at the Berkeley High School Independent Study Program since 2006 and was educated at Antioch College and CSU East Bay. Board games, visual art, tech and intellectual theory inform David’s mathematics instruction of all students, from those who initially despair about math to those who aspire to STEM professions. As a result, each of these students learns how they think about quantities,  uses math to navigate the world, and thinks critically.  In the words of Albert Einstein, “The important thing is not to stop questioning.”
