Student Achievement Comparisons

A study that surveyed Ontario science teachers on their beliefs about animal dissection found that over half of teachers indicate that they use dissection for pedagogic reasons; that dissection helps solidify student’s knowledge and reinforce concepts; and that it is the “best” way to learn about anatomy and physiology (Oakley, 2012). However, many studies have demonstrated that non-animal alternatives can also provide effective educational learning opportunities. Alternatives can typically be used multiple times, are cost effective, align with the 3Rs, and do not harm animals.

In a 2022 article in The American Biology Teacher, researchers conducted a systematic review of studies published between 2005 and 2020 that evaluated the pedagogical value of non-animal models versus animal dissection. They found that non-animal alternatives performed as well as, or better than, dissection in 95% of the studies.  

 

Alternatives 

There are numerous alternative resources for teaching about body systems that continue to be improved upon.
