What is NIELS ?
NIELS is a curricular unit consisting of a sequence of simulations
authored in the NetLogo modelling environment. Most students find
electricity a particularly hard topic to learn, whereas, most of
them find electrostatics is relatively much easier. Learning Scientists
suggest that this is due to the fact that we do not have access
to electrical phenomena at a microscopic level - i.e., at the level
of atoms and electrons. NIELS is designed to address this issue.
Models in NIELS depict phenomena aggregate-level phenomena such
as current, voltage and resistance as emergent - i.e., they arise
due to simple interactions between many individual-level "objects"
such as atoms and electrons. Using these models, students as young
as 5-th graders can actively explore and modify with the relevant
phenomena by interacting with the models at various levels - e.g.,
running glass-box experiments by changing values of variables on
the GUI and observing the resultant phenomena, and/or, by modifying
and extending the underlying Netlogo program. No prior knowledge
in electricity or programming in required.
We have succesfully tested NIELS in undergraduate, high school
and middle school classrooms. NIELS is currently being implemented
in elementary and middle schools in the US and Singapore.
