Abstract
As school teachers, difficulties often occur when
we integrate technology into mathematical teaching. Lack of tangible
examples and shared resources are possible reasons. We strongly
believe that electronic digital materials for teaching and leaning
should help the teachers present mathematical concepts more clearly,
and they can be used to provide interactive environments so that
students have chances to explore mathematical concepts and foster
conceptual understanding.
As we all know, Flash has been a powerful tool to create animations
on the web. We can design innovative and vital animations with Flash
in the Internet. And we find that with its strong functions, Flash
ActionScript could be used to create highly interactive software.
But Flash is the product designed for creating interactive webs.
As a user, we also find it is inconvenient when we use Flash to
develop electronic digital materials for geometry explorations.
In this study, we create a math function library to help developing
geometry digital materials. We also use it to build a series of
math interactive symbols and make Flash a useful tool to design
geometry digital materials. Finally a geometry software called Geometry
Player was developed to help teachers design and create learning
environments for students' learning. It provides environment to
manipulate geometry objects directly. It is simple and easy to use
the tools in Geometry Player to build and construct dynamic geometry
figures. They can manipulate and observe changes of dynamic geometry
figures to construct the geometry concepts by themselves. In this
presentation, some explorative activities developed by Geometry
Player will be shared.
