 Cost Analysis of Dissection Versus Nonanimal Teaching Methods
As more and more educators explore the benefits of nonanimal alternatives to dissection, software companies respond by developing ever more impressive technologies. New programs offer stunning educational advantages while reducing costs and decreasing reliance on animals. Alternatives cost thousands less than dissection, last for years, and several groups of students can use them simultaneously during each academic year. With nonanimal dissection methods, students can perform the lessons at their own speed, easily make-up missed classes, and review the programs until they have a firm grasp of the material. Students gain considerable computer experience and teachers have the flexibility to choose the anatomical detail appropriate for their class and grade level.
Although the initial cost of implementing a computer system is sometimes higher than that of dissection, over time, school systems reap financial benefits as multiple groups of students can use these same programs year after year. The following chart describes the average expense of using alternatives vs. traditional animal dissection over a 5-year period.

For administrators of elementary and secondary schools, budget concerns may become the greatest impetus for introducing alternatives to animal dissection. As budgets become smaller, computerized laboratories can alleviate the cost of maintaining a yearly animal supply. In the process these programs allow younger pupils to learn about animal anatomy and ecosystems at an earlier stage in science education. Instead of supplying the animals to one or two 8th grade classrooms, schools can incorporate innovative and technologically advanced teaching techniques into the science curriculum in lower grades. Students will not only have the opportunity to learn about the life sciences in early education, they will gain computer skills and see their application in the field of science.
Listed below are estimated cost savings for some of the most common animal dissections. Note that computer alternatives are one-time investments while animals and some dissection materials must be purchased every year.
