Abstract—Dynamic web-based learning tools are indispensable in modern teaching,especially considering their capability for
interaction on demand as a means of stimulating and engaging
students.The experience on which the results reported here are
based has grown out of progressive testing of different approaches
for publishing technical sketches and mathematical notations
from the field of electromagnetics on the web,starting in 1997
with simple static web pages of solved examples.The encouraging
results from using and evaluating this educational material and
the needs expressed by students for learning from more dynamic
and interactive web learning materials that offer the possibility of
changing parameters in online calculations motivated a search for
new approaches to publishing interactive learning materials on
the web.Integration of already developed components for building
animations,presenting mathematical equations,and performing
online computations with browser scripting led to development
of a learning environment where animations are synchronized
with corresponding derivations of equations and supported by
dynamic,parametric-driven calculations and visualizations that
can be integrated with sound and video.The system supports
tests and examinations in which the answers are provided as
mathematical notations.The use of Mathematical Markup Lan-
guage (MathML) permits equations in the learning materials to
be copied and pasted into most of the popular mathematical soft-
ware tools for algebraic manipulation or numerical computation.
Examples demonstrate how the system can be used with a course
on electromagnetics,although the basic approach is applicable in
other fields of engineering and natural science.
