dissection
Quick Summary
Dissection is the process of cutting apart an organism to study its structure. This biological technique has been used for centuries, dating back to the 1500s for medical instruction. In K-12 education, dissection became common in the 1920s, with millions of animals, such as frogs, fetal pigs, and cats, dissected annually.12
Dissection offers hands-on learning, developing fine motor skills, critical thinking, and problem-solving abilities. It can also inspire students to pursue careers in science and provides a way to utilize animals that have already died. However, ethical concerns exist regarding the sourcing of animals and the availability of alternatives like synthetic models and computer simulations, which offer comparable learning outcomes without the use of real animals.2
