“Back in the last century, people learned to operate computer software by reading thick manuals laden with obscure text and scant pictures. Or they attended training classes where they squinted at the instructor breezily demonstrating barely recognizable procedures. Or they clickety-click-clicked their way through the Help file, gleaning snippets of information but never weaving them into a coherent tapestry. Today, computer users can learn from a personal tutor who demonstrates the program, guides them through their initial efforts, monitors their growing skills, and certifies their mastery. Tools like Captivate, Camtasia, and TurboDemo make it possible for teachers and communicators to create effective software simulations–without programming. Even simple presentation tools, such as PowerPoint can create truly interactive simulations.” (William Horton – WritersUA)
