Just the facts, Jack. Don't get too fancy with your writing, especially at first. Make sure your facts are correct. Read Associated Press wire stories to see how to write print news. Then listen to local and national TV or radio news (CNN, WTOP) to help conquer broadcast writing. Remember: a lot of what you'll learn -- use active verbs, get to your point quickly, say things clearly, read your writing out loud -- is applicable in other classes and will improve your writing overall.
Listen to the guest speakers. They're all interesting and funny, but most importantly they're experts in their field. It's rare to have the opportunity to learn from and interact with so many accomplished people, let alone all in one semester.
Prof. Piacente makes the class fun and interactive, so speak up. Take advantage and enjoy!
