I've spent way too much time on this. Maybe I will forward it to the Hillsborough County school board.
To read the last word on this subject from the 2000 AVMA report, click here (PDF file)...

I've copied pertinent sections (inserting my own lettered notations in parentheses and bolding the sections which made this unacceptable in this instance). Forgive typos since I couldn't cut & paste from the PDF file.
This is from pages 682-3 (14-15 on Adobe)
DECAPITATION
Recommendations This technique is conditionally acceptable if performed correctly, and it should be used in research settings when its use is required by the experimental design and approved by the Institutional Animal Care and Use Committee.(a) The equipment used to perform decapitation should be maintained in good working order and serviced on a regular basis to ensure sharpness of blades.(b) The use of plastic cones to restrain animals appears to reduce stress from handling, minimizes the chance of injury to personnel, and improves positioning of the animal in the guillotine. Decapitation of amphibians
Those responsible for the use of this technique must ensure that personnel who perform decapitation techniques have been properly trained to do so.(c)
(a) This was obviously not killed for the purpose of research, much less research approved by the IACUC.
(b) Shovel does not = sharp blade.
(c) This person obviously has not been trained in euthanasia, or else she would be following the guidelines. We use a simple injection to euthanize, and in FL you are not even allowed to push the syringe if you have not been trained. Qualified training includes a veterinary doctoral degree, a veterinary technical degree, or a euthanasia certificate. If she were qualified to do this, she would have a piece of paper to prove it.

Rabbits
Acceptable
Barbiturates, inhalant anesthetics, CO2, CO, KCl in conjunction with general anesthesia
Conditionally acceptable
N2, Ar, cervical dislocation (<1kg), decapitation, penetrating captive bolt
Again, she did not meet the conditions.
Furthermore, even if this were an acceptable method, the point is that no one qualified had decided that the rabbits should die. I think that teaching kids to make uneducated life and death decisions while ignoring the fact that expert help is available, is a horrible lesson to be teaching.
