What is an agent-based model?
An agent-based model (ABM) is a computer simulation in which a collection of individual objects, called agents, interact with each other and result in emergent phenomena over time. ABM is a powerful tool for understanding about a complex system, as it allows users to explore and represent the relationships among the interconnected system elements. At present, ABMs have been widely used in various STEM and social science fields to study complex systems, such as ecosystems, weather systems, and human sociaties, .
Many software packets have been developed to create ABMs. The ABMs on this website are developed using NetLogo (Wilenski, 1999).
How do agent-based computer models support student learning?
Effectively presenting target phenomena related to population dynamics to young students.
Exposing students’ personal models and prior understandings of the targeted natural phenomenon
Provoking and supporting students in 1) elaborating the target natural phenomenon, 2) abstracting Patterns, and 3) revising conceptual models
Supporting tangible and productive conversations among students, as well as between instructor and students.
