SageModeler is a free, web-based systems dynamics modeling tool for middle and high school students to construct dynamic models. SageModeler is being developed at the Concord Consortium and the CREATE for STEM Institute at Michigan State University.
Modeling is key to how scientists approach understanding complex phenomena and how scientific and engineering problems are addressed. And like real scientists, students should explore systems and engage in system modeling as a necessary step in developing scientific literacy. A Framework for K-12 Science Education and the Next Generation Science Standards recognize the importance of systems and systems models as one of the key crosscutting concepts, and developing and using models as a key science and engineering practice.
SageModeler is an intuitive modeling tool for students to build their own models and validate their model design using real-world data. Research has shown that it engages students in the modeling practice and allows them to express their mental models in a way that can be discussed and tested.
