The Virtual Courseware Project produces interactive, online simulations for the life science laboratory or for earth science field studies.
The activities are designed to enhance an existing curriculum and include online assessments.
There is wide acceptance that inquiry-based curriculum programs have positive effects on cognitive achievement, process skills, and attitudes towards science.
The simulations are designed to enhance traditional curricula and provide a supplement to experimental laboratory and field work.
