Screen readers, such as JAWS, HOME Page Reader, Window Eyes, etc, will announce a link to the user before identifying the link. JAWS and Window Eyes will say "link: Module 1 Assignments". IBM Home page uses different voices, a male voice reads the content and a female voice reads links.
HTML standards indicate hyper-links by underlining the text, and sometimes by adding additional color (usually blue). At a minimum your links should be underlined. DO NOT underline text that is not a hyper-link.
