A virtual laboratory provides an on-screen simulator or calculator that learners can use to test ideas and observe results.
Here in the Heat flow laboratory, mechanical designers conduct experiments
to learn how heat flow depends on factors such as temperature, area, thickness,
and thermal conductivity.
This
HTML laboratory teaches HTML. Learners can use the arrow
buttons to advance through a series of progressively more challenging goals shown
at the right. Learners enter HTML in the text-entry area at the left and see their results in the middle column.
This example provides
measurement data and allows the learner to plot it by dragging dots into place on
the virtual graph paper. Doing so reveals a simple relationship between area and
heat flow, which makes even the most dull-witted learner shout “Eureka!”
The heat flow lab was built using Microsoft Excel and Crystal Xcelsius. The lab was embedded in PowerPoint and converted for Web delivery using Adobe Breeze Presenter. The HTML Lab was built using Adobe Dreamweaver and custom JavaScript. The drag-and-drop activity was built using Adobe Flash.
