The objective of this course is to teach deaf adults with basic English and Internet skills to use written English for international contacts (e-mail correspondence, reading English websites, etc.). SignOn! consists of ten lessons on Internet and Deaf topics. The topics are of a varying complexity. There is no fixed structure, i.e. the users can choose the topics according to their individual interests or needs. Each lesson contains a Main Text, which also introduces the most important words and phrases connected to the respective topic. Additionally, there are interactive exercises (multiple choice, matching and right order), which allow the users to check vocabulary, grammar, syntax, spelling and comprehension. More information and links serve to extend the users’ knowledge on their own. For this they can also use the “Toolkit” which refers them to on-line dictionaries and recommended websites for English as a Second Language.
