I think it is important to continually remind students of why they enrolled in school in the first place--to get a job in their field of study! In some classes (like general education classes), career college students struggle in finding how the course relates to their program of study. It is helpful when an instructor can create assignments or questions that relate to the students program.
I am a general education instructor, and I will simply ask my students how the unit we have just studied will help them with their career. I will also create scenarios in which the students may find themselves in for their job. For example, in my speech class I will ask the students to present a persuasive speech around a situation that they would find themselves in when they are on the job--persuading a boss to accept a proposal, persuading a customer to buy a product, etc. It is very helpful when a student can relate what they are learning to their career choice.
