Modeling is More Than Replicating

Students often examine and interact with models as they learn content. But is it really modeling when students create a 3-dimensional representation of a cell?

We’ll use the word “modeling” here to refer to the practice of developing and using models in science. Teacher modeling of behaviors, skills, and cognitive routines is incredibly important in classrooms, but this post will focus on students’ interactions with conceptual models.

From the page 50 of the Framework for K-12 Science Education:

Science often involves the construction and use of a wide variety of models and simulations to help develop explanations about natural phenomena. Models make it possible to go beyond observables and imagine a world not yet seen. Models enable predictions of the form “if … then … therefore” to be made in order to test hypothetical explanations.

Creating the cell representation pictured above might demonstrate a student’s ability to design to criteria or to recall the shape of organelles, but it isn’t really an explanation or prediction. Continue reading “Modeling is More Than Replicating”
