The Baltimore Sun, September 26, 2002
  • Diane Goldian, Principal, Kenwood SHS
  • "We have the CD ready to go, we have our plans
    in place, and we can deliver a good program.
  • Douglas Neilson, chief communications officer,
    Baltimore County Public Schools
  • "The school system will make sure that biology
    and anatomy teachers systemwide know they must
    offer a choice. And every student in Kenwood
    High's anatomy class will be given the option of
    using the CD-ROM.

  • 1998
  • The University recognises that some students
    may have a conscientious belief which is in
    conflict with teaching and/or assessment
    practices in one or more units in which they
    enrol. The University shall endeavour to make
    reasonable accommodations to meet such beliefs.

  • 1999
  • Murdoch was in a position to and should aim
    to conduct teaching that does not require animals
    to be killed specifically for this purpose by
    2005.
  • 2000
  • Murdochs first alternative veterinary surgical
    program 2 students granted alternatives to all
    the terminal surgeries - involving experience
    assisting with surgery and anesthesia in private
    clinics and animal shelters, and sterilizations
    of shelter animals. They gained 5 times as much
    surgical and anesthetic experience as their
    classmates, and performed 21 spays (female
    sterilizations).

Humane Alternatives to Harmful Animal Use in
Education
  • Preclinical Computer simulations, videos,
    plasticised specimens, models, ethically sourced
    cadavers, non-invasive self-experimentation
  • Surgical Surgical simulators, ethically-sourced
    cadaver surgery, supervised clinical experience,
    animal shelter sterilisation programs

7
Reasons for Use of Humane Alternatives
  • Ethical considerations
  • Legislative requirements
  • Teaching efficacy
  • Psychological impacts of harmful animal use
  • Respecting student beliefs
  • Economic advantages

8
Ethical Considerations
  • Numbers of animals used Close to six million
    vertebrates dissected annually in U.S. high
    schools alone.
  • Sources Biological supply companies, Class B
    dealers (licensed animal brokers) - have used
    animal shelters, strays, "free to good home" ads.
  • Biological supply companies
  • Inhumane killing practices.
  • Injection of still-living animals with
    formaldehyde-based preservatives.
  • Numerous violations of the federal Animal Welfare
    Act.
  • Adverse environmental impacts E.g., frog
    populations.

9
Legislative Requirements
  • Animal Welfare Act
  • The fundamental federal law intended to protect
    animals.
  • "animal any live or dead dog or cat or
    warm-blooded animal (excluding birds, mice or
    rats bred for research, and animals used for the
    production of food or fiber), used for research,
    teaching, testing, or that is a "pet."
  • The principal investigator in an experiment or
    procedure is required to explore the use of
    humane alternatives. This would include teachers
    in charge of animal-based learning exercises.
  • State animal protection legislation may also be
    applicable.

10
Comparative Studies of Student Performance
  • At least 28 studies covering all levels of
    education have demonstrated the superior or
    equivalent efficacy of alternative methods in
    imparting knowledge or clinical or surgical
    skills

    of animals in education. Online via www.hsus.org,

    study on the values gained from dissection of
    animals in secondary school biology. Science
    Education 52(2) 5557.
  • High school students who watched films of animal
    dissections (earthworm, crayfish, frog, perch)
    demonstrated greater factual knowledge of these
    animals than did students who performed
    dissections on them.
  • 2. Kinzie, M.B., R. Strauss J. Foss. 1993. The
    effects of an interactive dissection simulation
    on the performance and achievement of high school
    biology students. Journal of Research in Science
    Teaching 30(8) 9891000.
  • Findings suggest that an interactive videodisc
    was at least as effective as actual dissection in
    promoting high school student learning of frog
    anatomy and dissection procedures.

  • Post-test scores were equivalent for high school
    students who dissected earthworms and those who
    received a classroom lecture on earthworm
    anatomy.

    dissections on student acquisition of knowledge

    Cincinnati.
  • Approximately 175 high school biology students
    taught frog structure, function, and adaptation
    via lecture performed better on a post-test than
    did approximately 175 high school biology
    students taught by doing a frog dissection.

    achievement and attitudes in a pilot study

  • Two groups of high school students performed
    equally on a test following either animal
    dissection or interactive videodisc simulation.

14
Other Advantages of Humane Alternatives
  • Time savings
  • Staff savings
  • Cost savings
  • Unlimited numbers of virtual animals
  • Greater flexibility of learning

16
Negative impacts of harmful animal use
  • University of Illinois veterinary students,
    1999, re learning benefits of terminal first
    year physiology laboratories
  • "It was difficult to get any great understanding
    of physiology because we worried most of the time
    about not having our dog bleed to death or die of
    anesthetic overdose before the experiment was
    over. In the end, what I learned about physiology
    (cardiology and respiratory physiology) I taught
    myself from the notes."
  • most of us were too preoccupied with having
    to kill the dog that physiology wasn't
    concentrated on
  • Nothing that was covered in those labs could
    not have been learned from a demo, or a video.
    The guilt I felt for participating outweighed all
    beneficial aspects of the experience.

17
  • The stress of the whole ordeal was worth
    nothing in the end. I studied from these books,
    not from my lab experience.
  • During one lab, my group accidentally killed
    our dog with anesthesia overdose because of lack
    of experience and the impatient ill-given advice
    of a professor. The experience overshadowed the
    benefit gained by the first lab.
  • Conclusions 59 believed the non-survival
    animal physiology labs were not "worth the
    resources used". Only 20 felt they gained
    "great benefit" in their understanding of
    physiology from the laboratories.

18
Psychological Impacts of Harmful Animal Use
  • Negative underlying message about intrinsic value
    of animals lives, development of a utilitarian
    view of animals.
  • Risk of psychological trauma resulting in
    impairment of cognitive abilities, decreased
    learning, and loss of interest in the sciences -
    female students most commonly affected.
  • Desensitization to suffering and killing.
  • Diminished capacity for compassion and ethical
    decision making.

19
Respecting Student Beliefs
  • Legislative issues
  • E.g. Safia Rubaii, University of Colorado School
    of Medicine, 1995 Sued for 95,000 after failing
    physiology because she refused to perform a
    required experiment at Colorado which involved
    giving a lethal injection to an anesthetized dog,
    and being forced to retake it at the Creighton
    University School of Medicine in Nebraska, where
    harmful animal use was not required.
  • Eight states with student choice legislation or
    policies
  • California, Florida, Illinois, Louisiana, Maine,
    New York, Pennsylvania, Rhode Island.
  • Publicity issues

20
Economic Advantages
  • Costs of laboratory animals
  • Purchase
  • Transportation
  • Housing
  • Feeding
  • Veterinary care
  • Experimental anesthesia
  • Euthanasia

21
A Cost ComparisonAnimal Dissection vs. Humane
Alternatives
  • Typical biology department over a three year
    period
  • Animals dissected frog, fetal pig, cat and
    dogfish.
  • 3 classes comprised of 30 students each, every
    pair of students dissects each species of animal
    once. Hence 45 frogs, 45 fetal pigs, 45 cats and
    45 dogfish needed annually, or 135 of each over a
    three year period.
