ab: We present in this paper several interactive web-based tools for visually
exploring various linear algebra concepts, tools that are not
constrained by the requirement of owning particular software. By
building these tools with JavaSketchpad, the only requirement for a
user is a Java-enabled browser. In particular, we present three tools,
GridMaster, Transformer2D, and Eigenizer, and a couple of bonus items
for advanced linear algebra. Each of these tools permits students to
interact with both algebraic and geometric representations of concepts
such as change of bases, coordinate systems, linear transformations,
eigenvalues, and eigenvectors. We include student reactions to enhance
the discussion and identify the effects of using such tools as part of
linear algebra explorations. (Authorsâ€™ abstract)
