As evident in the names of the 5 phases above, they all start with the letter E. Hence, this version of the Learning Cycle is sometimes referred to as the 5E model (Trowbridge & Bybee, 1996). The most important characteristic of this model is that the phases are connected to each other and flow from each other. Thus, what is done in one phase forms the basis for what can/should be done in the next phase. These connections between the phases provide a logical progression to the lesson, which can last for longer than one class period. They also make it possible for students to experience scientific inquiry the way scientists do and problem solving the way engineers do. Thus, the 5E model offers an effective approach to implement STEM-oriented instruction. Figure 1 below may help the visual learners among you to get a better grasp of the 5E model of Learning Cycl
