How do you motivate students in "required" or pre-requisite course?

As a medical coding and billing instructor, I find it difficult at times to change the perception of adult learners. I've had a few aldut learners that had worked in the field and returned to school for the certification. Not having the proper training and/or basic foundation, they have developed bad habits and inaccurate approach that is difficult for them to break. How can I address this situation without being negative and creating additional stress.
