The conveyance of these concepts is my fundamental responsibility as an instructor. However, I also want the students to be able to apply these principles to new problems and recognize the limitations of those principles. Application of the principles typically increases the student's appreciation for the subject. A good biology instructor stresses the process of doing science as well as learning biological concepts. Students need to understand and experience the scientific method.
Experience teaches best.
I do not lecture about something if the class can do it. Students learn best by doing and being actively engaged in their own education. I also link course concepts with the students' lives. By demonstrating how course material relates to their lives and futures, I am able to maintain student interest and motivation. I frame problems, projects, and exams as real applications of the course material.
