Abstract: Ecological ponds can be a good teaching tool for
science teachers, but they must be built and maintained properly to
provide students with a safe and suitable learning environment.
Hence, many schools do not have the ability to build an ecological
pond. This study used virtual reality technology to develop a webbased
virtual ecological pond. Supported by situated learning theory
and the instructional design of “Aquatic Life" learning unit,
elementary school students can actively explore in the virtual
ecological pond to observe aquatic animals and plants and learn
about the concept of ecological conservation. A teaching experiment
was conducted to investigate the learning effectiveness and
practicability of this instructional design, and the results showed that
students improved a great deal in learning about aquatic life. They
found the virtual ecological pond interesting, easy to operate and
helpful to understanding the aquatic ecological system. Therefore, it
is useful in elementary science education.
