Models should include the interactions between variables to explain a phenomenon. For example, when modeling the health of an individual with diabetes. The afflicted person is impacted by diet. On paper (or a whiteboard), this would likely take the form of an arrow connecting diet to health. It does not show that the health of someone with diabetes can be impacted positively with good nutrition and impacted negatively with poor nutrition. The same is also true for many of the other variables involved in this model; environment, exercise, etc. Another limitation of the paper model is that it doesn’t allow students to test their model.
Using a dynamic modeling tool, such as SageModeler, students can overcome the problems associated with paper models. SageModeler is a free web-based systems dynamics modeling tool for secondary school students to construct dynamic models and validate their models by comparing outputs from their own models and data from one or more other sources, including experimental data from probes or data generated by simulations. The tool is used to engage learners in three-dimensional learning by using crosscutting concepts (systems and systems modeling, cause and effect, and energy and matter) with various scientific practices (particularly modeling, but also analyzing and interpreting data and engaging in argument with evidence), integrated with disciplinary core ideas.
To facilitate model validation, SageModeler and all external data sources are embedded in a Common Online Data Analysis Platform (CODAP). CODAP is an intuitive graphing and data analysis platform that takes the outputs from the system dynamics models, as well as any other validating data source, and blends them into a single analytic environment.
Learn to use SageModeler so you can facilitate it with teachers in your region.
- Learn to use the tool in-depth to work with teachers in your region. Better yet, bring a teacher with you. Then, try it in their classroom and learn together to become a more proficient user and facilitator of the tool.
- Gain access to CREATE for STEM middle school and high school units that are designed for NGSS and use SageModeler. The tool can also be used to enhance most secondary units from your own curriculum.
