eLearning and mLearning designers are experiencing a new challenge that mirrors one that’s age-old. In the 1980s, WYSIWYG (what you see is what you get) was a challenge for computer users who saw one thing on their computer monitors but saw very different results when they printed their work. Today, the new challenge for eLearning and mLearning instructional designers is WYBIWYG (what you build is what you get). What are the common elements that lead to WYBIWYG issues? What can you do to avoid it? Can you eliminate it? This presentation will help you understand how it happens, what to do to avoid it, and steps you can take to eliminate WYBIWYG issues entirely.
