Marcella McCollum

Dr. Marcella McCollum was featured in the SJSU story "Transforming the Way We Teach" which focused on the Lurie College of Education's Strategic Plan initiatives.

We need to think about changing paradigms,” says McCollum. “We cannot just offer a class or textbook that tells you how to overcome the challenges that exist in our current educational systems as they are designed. We want students to question why things are the way they are. We want them to have the tools, so they can push back when something looks unjust.”

Pei-Tzu Tsai and Grace Shefcik

Dr. Peitzu Tsai co-published "Voice-related Experiences of Nonbinary Individuals" in the Journal of Voice with CDS alumni Grace Shefcik, who also received the SJSU Outstanding Thesis Award for the 2020-2021 academic year.
