![]() ![]() ![]() Approximately half of the student groups participated in a virtual On-line dissection, the other half in an actual laboratory dissection. What were the perceptions of the teacher's using it? How does student achievement compare among three the different ability levels on a pre and posttest regarding basic frog anatomy? Is a virtual On-line dissection a suitable alternative for students who, for whatever reason, do not participate in the actual laboratory experience? The subjects consisted of 218 biology students among three different ability levels, in a Northeastern suburban high school. The purpose of this study was to investigate how a virtual On-line frog dissection compares with an actual laboratory dissection. ![]() For a variety of reasons, performing an actual or conventional animal dissection may not be a desirable option. Alternatives to actual dissections have been developed in recent years. A number of states now have legal proceedings or statewide policies requiring that alternatives to the actual dissection of laboratory animal specimens be permitted in their school districts. Objections by students, based on religious or ethical grounds, have been raised regarding the dissections of animals in classroom laboratories. conventional laboratory dissection: A comparison of student achievement and teacher perceptions among honors, general ability, and foundations-level high school biology classesĭissecting animal specimens has long been a tradition in biology classes. Virtual dissections were done with V- Frog, a… Subjects were secondary students enrolled in year-long life science classes in a suburban high school (N=102). The purpose of the present study was to examine and compare the effectiveness of virtual frog dissection using V- Frog and physical frog dissection on learning, retention, and affect. Battaglia, Barbara Brophy, Keith Chugh, Kevin Honors for the Virtual Frog Dissection Kit Study Web The dissection kit received a StudyWeb award Frog Project | Virtual Frog Page last modified: 01/23/05 Contacts: Bill Johnston, David RobertsonĪ Comparison of V- Frog to Physical Frog DissectionĮRIC Educational Resources Information Center Honors for the Virtual Frog Dissection Kit You can interactively dissect a (digitized) frog named Fluffy, and play the Virtual Frog animals other than the frog that have a computer-graphics based virtual dissection page. Non-animal methods also allow students to repeat the material until they’re confident with it, instead of just getting one shot to make the right cut.Virtual Frog Dissection Kit This award-winning interactive program is part of the "Whole Frog " project. Instead of buying dead animals year after year for class after class, schools can purchase a computer program once and then use it repeatedly. There are lots of modern, educationally superior alternatives to dissection, and they can even help schools save money. Basically, frogs help protect you from mosquito bites by keeping the bug population in check! Not only is stealing frogs from their homes and killing them cruel, the removal of frogs from ecosystems also disrupts nature’s delicate balance-populations of waterborne insects skyrocket, resulting in increased crop destruction and the spread of diseases such as malaria. “I know of several biological supply houses in Louisiana and Mississippi which are notorious for finding a pond and collecting every living thing to be found within it … many of our states’ ponds and bogs are devoid of herpetofauna because of this practice.” Department of the Interior has stated that declines in amphibian populations can be attributed in part to the use of amphibians in dissection. Frogs are also among the first species to succumb to environmental pollution and habitat destruction, and their deaths are often the first indicators of environmental problems because they’re so sensitive to their surroundings.Īll species of frogs are disappearing from the Earth at an alarming rate, with a devastating and not yet fully understood environmental impact. As a result, some frog populations have crashed, wiping out entire species. Populations of grass frogs and bullfrogs, the most common victims of high school dissection, are threatened by both mass collection and environmental hazards. ![]() Sadly, frogs are the most commonly dissected animals in classes below the university level, although other species, like cats, mice, rats, dogs, rabbits, fetal pigs, and fish, are also sometimes used. ![]()
