What is NetLogo?<br />

NetLogo is a programmable modeling environment <strong>for</strong> simulating natural <strong>and</strong> social phenomena. It<br />

is particularly well suited <strong>for</strong> modeling complex systems developing over time. Modelers can give<br />

instructions to hundreds or thous<strong>and</strong>s of independent "agents" all operating concurrently. This<br />

makes it possible to explore the connection between the micro−level behavior of individuals <strong>and</strong> the<br />

macro−level patterns that emerge from the interaction of many individuals.<br />

NetLogo lets students open simulations <strong>and</strong> "play" with them, exploring their behavior under<br />

various conditions. It is also an authoring environment which enables students, teachers <strong>and</strong><br />

curriculum developers to create their own models. NetLogo is simple enough that students <strong>and</strong><br />

teachers can easily run simulations or even build their own. And, it is advanced enough to serve as<br />

a powerful tool <strong>for</strong> researchers in many fields.<br />

NetLogo has extensive documentation <strong>and</strong> tutorials. It also comes with a Models Library, which is a<br />

large collection of pre−written simulations that can be used <strong>and</strong> modified. <strong>The</strong>se simulations<br />

address many content areas in the natural <strong>and</strong> social sciences, including biology <strong>and</strong> medicine,<br />

physics <strong>and</strong> chemistry, mathematics <strong>and</strong> computer science, <strong>and</strong> economics <strong>and</strong> social psychology.<br />

Several model−based inquiry curricula using NetLogo are currently under development.<br />

NetLogo can also power a classroom participatory−simulation tool called HubNet. Through the use<br />

of networked computers or h<strong>and</strong>held devices such as Texas Instruments (TI−83+) calculators, each<br />

student can control an agent in a simulation. Follow this link <strong>for</strong> more in<strong><strong>for</strong>m</strong>ation.<br />

NetLogo is the next generation of the series of multi−agent modeling languages that started with<br />

StarLogo. It builds off the functionality of our product StarLogoT <strong>and</strong> adds significant new features<br />

<strong>and</strong> a redesigned language <strong>and</strong> user interface. NetLogo is written in Java so it can run on all major<br />

plat<strong><strong>for</strong>m</strong>s (Mac, Windows, Linux, et al). It is run as a st<strong>and</strong>alone application. Individual models can<br />

be run as Java applets inside a web browser.<br />
