This article described the meaning of the rewards icons use in the Qedoc Quiz Player.
Trophies are awarded for accuracy, as a percentage of the material in the activity which is correctly known by the learner. A gold trophy, for example, means that the learner has acquired a comprehensive knowledge of the material in a specific activity.
There are different colours of trophy to indicate accuracy. If accuracy is very low, there is no trophy at all. Overall there are 6 trophies, with bronze, silver and gold being topped by a gold-with-star version.
Accuracy is accumulated over time and can be increased (or decreased) by repeating an activity. Accuracy is calculated differently depending on the activity type. While good accuracy can be easily reached on a quiz, a flashcard deck offers a greater challenge and will expect each item to be correctly answered a number of times before it is considered to be fully known.
Shields are awarded for tenacity rather than achievement. The idea here is that everyone should get something, so those who can't get anything for their poor achievements can at least be happy with a shield. Shields are awarded for the number of times an activity is attempted. With increasing numbers of attempts, the colour of the shield "improves" until finally a gold shield and then a gold-with-star shield are awarded.
Stars are awarded for raw points and reflect a combination of accuracy and tenacity. With increasing numbers of points, the colour of the star "improves" until a gold star is reached. When designing a module, you should think carefully about how many points to allow for each question, so that a student can reach a gold star with a reasonable but not insuperable effort. A student effectively has two strategies for maximizing raw points: either make as many attempts as possible and reach a mediocre score on each, or maximize score on each attempt to reduce the effort of repeated attempts.
A ribbon is awarded if gold level is reached in all the other three categories of measurement (above). A ribbon indicates that the learner has pretty well exhausted the learning potential of an activity.
