I teach surgery and anesthesia at a Vet Tech Institute. The age of our students ranges from: right out of high school to ~40 (career change). These students are easy to "mold" and are receptive to learning. We also have students that have been working in the field as assistants for pieriods of time. I am all for on the job training, but some of these students are set in their ways and it not always the 'right' way. How would you approach them in a positive way to help guide them in the correct direction without making them? I have had students tell me that "thier doctor at work says we are wrong for showing them how to do 'x' this way"
