Mrs. Lesli Barron

This is my 28th year of teaching and I have been at Oswego High School since 1995. I hold bachelor’s and master’s degrees in secondary science education from Kansas State University in Manhattan. I began my career at Holton Middle School in Holton, Kan., where I taught seventh grade physical science for two years. I currently teach honors and Advanced Placement chemistry but have also taught physical science, biology and regular chemistry.

Science was never my favorite subject in high school. After taking many biology and chemistry courses in college, I began to think that perhaps I could help high school students learn and enjoy science in a way that I never had. I enjoy coming to work every day. I still feel passionate about teaching even after 25-plus years. I feel that even if my students are not crazy about chemistry, they still enjoy being in my classroom.
