　　Earlier thisyear, a graduate student from Simon Fraser University in Vancouver designed thefirst-ever haptic frog dissectionprogram, which uses a penlike tool to create a sensation similar to cuttinginto real flesh. The hand-held device connects to a computer, and students movethe device through the air while watching the results of their actions on acomputer screen.

　　With DigitalFrog-a popular program thats had approximately 1,500 frog demo downloads since January and iscurrently in use in 2,000 schools-students can add or subtract those amphibiousorgans with a mere mouse click. They can then assess their learning withsporadic frog anatomy quizzes.

　　Repetitionis helpful. The fact that a student can review sections of a program over andover again is important, says Martin Stephens, vice president for animalresearch issues at the Humane Society of the United States. Indissections, the animals organs are all shriveled and discolored. You look for things and cant find them because body partshave changed drastically since the animal was killed. But on a computer screen,layers can be digitally peeled away. Other experts think the dissectiontechnology has its limits. Gerry Wheeler, executive director of the NationalScience Teachers Association, says that artificial simulations dont give as enriching an experienceas the real thing. Still others worry the programs are depriving kids ofexperiential learning.
