How do you make students interested in a technical subj?

Congratulations on your new profession. First, every student is different so keep that in mind. What you could do is conduct a survey to find out how the students prefer to learn their lessons. In most of my classes, the professor would place up on the board critical elements that would be on the test. It worked like this: Discuss content that will be on the test. Get students interesting by applying real life concepts. Be humorous. Assign chapter reading. Tell students to read only parts that are important. Otherwise, students will be reading the whole chapter and will not have time to focus on material for the test. You could always have your students design technical storyboards using outside objects, or even fantasy ones. Personally, I love a class where I'm free to expand my mind instead of keeping it limited. But I think the survey would definitely assist you in finding out what the students would prefer.
