Science lessons that follow the 5E model -- engage, explore, explain, extend, and evaluate -- put a structure in place that help reach adolescents in middle school and high school. Piaget originally proposed how children's intelligence and abilities change as they grow, and this understanding is important when designing science lessons. Piaget referred to the concrete operational stage (ages 7-11) and the formal operational stage (ages 11 to adulthood). My teaching style is hybridized -- some days I am the facilitator or coach, and other days I am a lecturer. How I teach is dependent upon what and how I intend to teach the topic.
