Abstract

<p>This research aimed to develop the teaching material in dissection using fresh-water fishes. Three popular species in Japan, Micropterus salmoides, Lepomis macrochirus and Carassius auratus langsdorfi, were used in dissection. The purpose of the dissection was to find out the structures of the outer form, digestive organ, heart: heart beating, sexual organ, central nervous system, eyes; lens and so on in detail. The whole process took about one hour.</p><p>The results of observation showed that the dissection using fresh-water fishes for dissection is good because the fishes are easily available as teaching materials for junior and senior high school. It is easy for the teacher to get these materials, and less repugnant for students to participate in dissection. Furthermore, this material is available for pre-service and in-service teacher training, and so, they will be able to acquire the skill and educational use of dissection.</p>
