I think that models are a very effective way for students to learn. The students get the opportunity to create and manipulate a model to add a tactile component to the long-term memory. Usually in the process of using a model, students also get to discuss the processes and ideas they may have with one another. Often, the process of discussion is the best way to learn. Students will also discover misconceptions that they may have through these discussions. The non-linguistic representation is also very valuable for ELL learners, special education students, and all other learners. Often, as a teacher, I learn through observing the students create and manipulate a model as well!
