When implementing STEM activities, such as model rockets blasting off or paper airplanes flying across the room, the mathematical or scientific content can get lost as we focus on the “wow factor.” However, meaningful learning experiences can be implemented anytime by employing the components of the 4E×2 instructional model. In essence, the model promotes students exploring their ideas before constructing an explanation for their concept, allowing the development of deeper understanding and connections with multiple conceptions.
