Have them write four messages of no more than 140 characters each to persuade other college students to take the business communication course. They should think of the first message as the “headline” of an advertisement that makes a bold promise regarding the value that this course offers every aspiring business professional. The next three messages should be support points that provide evidence to back up the promise made in the first message.
As they think about ways to promote the course to other students, your students will have the opportunity to think through what you've shared with them in class so far about the value of the course and to visualize themselves putting their new skills to work.
If you prefer not to use Twitter for this, students can submit their messages using any medium you choose.
