Dr. William Kroen

Professor of Biology

Why I Teach

I teach at a small college because I believe that students understand more when guided to make connections on their own. In the life sciences, the more you understand how the systems work, the more you can appreciate the intricate beauty of the natural world. I work diligently to lead beginning students to gain knowledge, be inquisitive, see patterns, and connect their understanding to their own experiences. First-year students conduct several course-embedded experiments, gaining experience in asking questions and manipulating data. Routine appointments with advisees allows me to encourage students to build their initiative and planning skills.

Professional Activities

I have been active with the Four-Year College & University Section of the National Association of Biology Teachers for more than twenty year, having held a number of leadership positions that culminated in service as Chairperson for 2010. I present my own teaching activities each year at the annual Professional Development Conference, gaining feedback and ideas that continue to improve education at Wesley. One major teaching/learning thread is to have students explore hypotheses using real-world environmental data; these activities were published in The American Biology Teacher in November 2015. This teaching-learning experience allowed me to mentor a Wesley student who developed an inquiry-based lab module on pesticide safety in foods; her research was presented at the National Conference for Undergraduate Research in 2019.
