Games principles are similar to a constructive approach to learning. Crisp  presents a table that matches game design principles with learning design. Games may be used for authentic assessment activities with frequent rewards. Feedback is provided in response to actions of the game and student is rewarded when achieves goals. Mistakes will be made and corrected. The main goals of gaming and learning are different. In gaming students have to win. In learning students have to learn and apply. In gaming, sometimes students don’t master the necessary skills but are still able to win. To assess this type of task it is necessary to clarify what are the expected LOs.
Another problem is that games are difficult to develop specially if they have a strong programming and design component, like in videogames. Some games may be simpler in terms of technology. Quizzes or discussion forum may be used to implement the game and corresponding assessment. A game has a goal and tasks that have to be completed to achieve the goal and these may constitute the assessment criteria. What is assessed, the product or the process? If it is the process, then the game must allow tracking the process. This can be very complex and difficult to implement.
