The 5E's are a helpful guide for initiating hands-on inquiry-based teaching and learning in your classroom. Created by Dr. Rodger Bybee of BSCS in Colorado, the E's stand for Engage, Explore, Explain, Expand, and Evaluate. The Engagement step has students attention drawn to the topic through questioning strategies (i.e. Bloom's lower level questions) to assess how much students know on the topic being introduced and to give you a chance to correct misconceptions. Explore places hands-on materials with labs and experiential learning in the hands of the students while you guide them through the concept with more questions now in the mid-high range of Blooms so they can start connecting the concept with vocabulary and helps them to critically think about what they are observing. Explain then concretely connects the actual vocabulary to what they did in the exploration phase. Expand provides more opportunities for students to learn about the concept through other activities such as research, project-based learning, field trips, etc. Finally evaluate is your chance to use formative and summative assessments to measure how successful those experiences were in learning.
