Given the diversity of student experiences, identities, and academic backgrounds, how can we cultivate classrooms that are both welcoming and rigorous? My teaching philosophy is built on five core principles: setting high expectations with structured support, fostering a culture of belonging, ensuring accessibility through flexibility, investing in the teaching team, and committing to continual informed improvement. Through evidence-based strategies such as active learning, ethical discussions, and real-world applications, I aim to empower students to engage deeply with course content while embracing their place within the broader STEM community. Additionally, I emphasize the professional development of undergraduate and graduate Teaching Assistants, equipping them with the tools to facilitate dynamic discussions and inclusive learning environments. In this seminar, I will share how these approaches create a space where all students—not just the most confident or well-prepared—can succeed, contribute, and develop a lasting sense of belonging in STEM.
