Ethan Edwards of Allen Interactions likes to make the point that we can't make people learn. You can't learn someone to do something. You have to create the conditions where they want to bring the information to themselves. And games are a great place to create a sense of engagement.
Games create a new world, one with rules that put constraints on actions. In terms of training, this creates a safe place to fail. It's safer to get an ethics policy wrong, or fail to correctly describe new software, or to say the wrong thing to customer, in a game than it is in real life.
Voice-over takes a long time to record and adds cost to any elearning project. For a professional effect, you often have to hire talent. You have to record, listen, re-record any errors, synchronize with the presentation, publish, correct any errors. Outside of the cost of hiring talent (which you can get around by using in-house), there is still the cost in time and money.
In this white paper, E-Learning Council speaker Linda Warren and Mike Hruska discuss the significance of the Experience API also known as xAPI and “Tin Can”. The jump from SCORM to xAPI is a big one and learning managers and designers need to be aware of the limitations of SCORM and how xAPI is designed to address them.
