(Janet Eyler, "Emotion and Learning: Feeling our Way Toward a New Theory of Reflection in Service-Learning")

Effective reflection engages both teachers and students in a thoughtful and thought-provoking process that consciously connects learning with experience. It is the use of critical thinking skills to prepare for and learn from service experiences. [citation: Learn and Serve America's National Service-Learning_Clearinghouse. Glossary. Scotts Valley, CA: Author, 2003]
The term "reflection" is derived from the Latin term reflectere -- meaning "to bend back." A mirror does precisely this, bend back the light, making visible what is apparent to others, but a mystery to us -- namely, what our faces look like. In service learning, we look to develop processes that allow the people doing service to bend the metaphorical light of their experiences back onto their minds -- to make careful considerations about what their experience were all about: what did they see, who did they meet, why is there a need for such services in the first place, etc. The act of reflection, therefore, becomes crucial to their education. It serves as the bridge between experiences and learning.

"Reflection is a process of seeking clarity about truth, it demands consideration of one’s internal state (beliefs, feelings, assumptions) and external circumstances (actions, relationships, power dynamics, obstacles). It also demands a self-honesty and humility that will hold its own against affront from any quarter. "
