![]() “produced new evidence that cast serious doubt on the … likelihood of obtaining a conviction.”Ī key part of the “new and credible evidence” was a written opinion from a University of Minnesota veterinarian “who credibly challenged the other evidence suggesting animal cruelty had occurred,” Jacobson said. The company was charged with animal cruelty early this year, but Alexandria City Attorney Tom Jacobson dismissed the charges in April. PETA’s media alerts on the protest emphasized an “expose” that purportedly showed, or referred to, workers drowning conscious pigeons, injecting live crayfish with liquid latex dye to kill them and refreezing turtles that had come back to life after originally being shipped frozen to Bio Corp. Protesters outside the administrative offices held signs referring to animals bought “from a warehouse of horror,” and a “dissection supplier” that “drowned pigeons.” Science is about getting your hands dirty.”ĭistrict 113 is one of Bio Corp.’s customers. Collections of Anatomy Images Anatomy (Dissections) - Frog, pig, etc. FVTC has bought two, one located with nursing and one that is in public safety. “It’s another to see the size and scale, the diversity. Dissecting A Frog: A Middle School Rite Of Passage : NPR Ed In science classrooms across the country, middle-schoolers will take part in an iconic activity this year: frog dissection. Automage is the company that makes the virtual dissection tables. “It’s one thing to see it on a computer screen,” Reeves-Pepin said. Some of them use computer programs to dissect a frog on-screen. The digital version also can complement dissection, she added, but she also noted that dissection can inspire a student to pursue a career in biology - or can discourage it. Is it helpful or harmful to dissect frogs in school. She noted that many schools are diligent in requiring specimen vendors to provide information on the source of the animals.Ĭomputer simulations should be available to all students who might be repelled by dissection, Reeves-Pepin said. Those who use it and those who use alternatives respect each other’s choices, she said. Frogs are also among the first species to succumb to environmental pollution and habitat destruction, and their deaths are often the first. In her 10 years with the association, she said she’s never heard a “heated discussion” among teachers over the use of dissection. 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. She remains a firm believer in the value of specimen dissection in teaching anatomy and physiology.Īmong teachers, decisions about using dissection typically center around whether students are mature enough for such an exercise, Reeves-Pepin said. In recent years, biology instruction has shifted toward the study of cells, molecules and genetics, said Pfannerstill, who has taught biology for nearly 24 years, the last five at North Shore Country Day School in Winnetka. Dissection is a valuable and effective tool that allows scientists to learn about the organ systems of living creatures. But what may really persuade schools to move to a virtual experience is that the software is a lot cheaper than buying the traditional frog kits.She and other teachers also pointed out that simulations are less expensive than the use of real animals. ![]() Dissections are also environmentally questionable since the frogs are preserved in formaldehyde, and students often touch these chemical coated frogs with their bare hands. The move to a virtual experience would certainly be welcome for students who find the experience of cutting into an animal inhumane or disgusting-I remember my freshman year lab partner fainting while we worked on our frog. frog dissection lab report objective: frogs belong to the class amphibian. In comparison, a student can dissect a virtual frog over and over and just undo any mistakes with the click of a mouse. of the digital lab report will require another 2 hours in the computer lab. Kerry Kriger notes that he has "a doctorate in environmental science and I've never dissected a frog in my life." He says the virtual experience is actually preferable because if a student accidentally snips something she shouldn't have in a real-life dissection, the project is wrecked. In my Biology 11 program, the frog dissection follows the dissection of the. A George Mason University study also found that students taught with Digital Frog 2.5 learned anatomy and physiology faster and more effectively than students taught with traditional preserved frogs. Computer simulations and learning science: A review of the literature (in press). But do students actually learn as much if they can't hold the frog and touch it? In 2008 the National Science Teachers Association approved the use of virtual animal dissection software and many veterinary and medical schools are making the switch. This study examined the prior use of simulation of frog dissection in.
