Systems Thinking about Infections

Infection Game
from the Shape of Change

As we deal with a world-wide pandemic, there are many ways to help our students cope. One of them is just talking about what is going on, how they are feeling, the practicalities of their lives in a quarantine situation, and how to think about infections from a 10,000 foot perspective (meta-cognition.) Another is figuring out what useful enrichment activities would be helpful and fun.

This HONGJIU Ladies Winter Hats,Beret Winter Berets Women Winter Felt, especially for younger students, is a start in meta-cognitive understanding. This CLE simulation and others are available on the isee Exchange - a great resource for accessible simulations.

COVID-19 Modeling

COVID seems to be an on-going and persistent issue that has a lifecycle far longer than anyone thought when it emerged on the scene. An interesting initiative was started by Maurice Glucksman and Kim Warren in the UK. They created a contest for students to look at the spread of COVID within their localized areas. They created a system dynamics model and on-line courses for students to learn and utilize the model without needing to learn sophisticated modeling skills.

These courses and articles are available at The COVID-19 Localization Modelling Group.
