Here at the science department at my school they have a focus on implementing the 5 E’s (also known as e5) teaching and learning model. Using the stages of Engage, Explore, Explain, Elaborate and Evaluate in curriculum development.
Firstly, you don't have to incorporate all 5 E's at once - or in the same lesson. It is more a overall model to help design or structure a topic. It starts with an engage activity - it might be a big question, a current problem/event or a picture. The way I see this stage is it gets the students hooked and involved with the upcoming topic.
Another thing to note is that the Explain and Explore an cycle round - in fact most can. As there will be times where students Explore then the teacher will need to Explain before Exploring again.
