Models
They both work.
High fidelity models may appear and/or feel realistic. These tend to be more expensive, meaning fewer are available for student use. Low fidelity models may lack realism and still be very functional. Students tend to prefer the high fidelity models. To be effective, models need to stimulate students to practice the skill in a realistic manner. With attention paid to the crucial steps, both low and high fidelity models can be very effective.
Cadavers can be very useful and come closest to live tissue, particularly if kept fresh (vs embalmed or frozen).
NOVICE (network of veterinarians in continuing education) is a great source for ideas as is visiting other programs.
Simulation based training
Simulation based training has predominated in medical skills training. There is evidence that sims-based training success can transfer to real patients and can improve patient outcomes. Limited replication has been performed but results are supportive. The next step is to assess cost effectiveness of the programming due to expense (people, models and time).
