Teaching Philosophy

I believe learning should be a perpetual endeavor in life that is often achieved through multiple processes such as visual, auditory, repetitive, and hands-on approaches. Each student may possess a mosaic of learning styles and have the potential to excel when given the right tools and opportunities. In my classes, I try to integrate different teaching styles in order to address the variety of learning methods that exist and to generate sincere interest among students regarding the diverse topics of biology. I believe teaching is a dynamic process that requires professors to be vigilant in adjusting and applying new methodologies to meet the needs of our students in varying courses and disciplines.

It was good to simplify and reconnect with my initial and fundamental interest in aquatic biology; fishing.

Christensen, D.R. 2013. Pike Congregations. American Angler. January/February: 20-21. This was another article I submitted for fun as a way to stay connected with my fundamental interest in fish and their habitats.
