Spaced repetition tests

Spaced repetition is a learning technique that incorporates increasing intervals of time between subsequent review of previously learned material in order to exploit the psychological spacing effect.

This technique was popularized in the 70's by Sebastian Leitner and implemented by means of flashcards techniques. Computer based implementation of this concept differs slightly from the original proposal but substantially is the same. Siette make its own implementation of this methodology.

The main idea behind this methodology is to use testing as a learning resource. The goal is to learn or memorize the answers to a set of questions by taking a test repetaedly. The first time that a student take a test, questions are selected randomly, but in the second session, the probability of selecting a given question change according to the answer given before. The rule in Siette is that a question that has been failed increases its probability to be selected twice, and if the previous answer were correct, the probability reduce to a half. The selection of questions for the third test takes into account the answers given in the two previous test, increasing or decreasing the probability of selecting an item accordingly. To sum up, everytime a question is answered in a test session, the probability to be selected in the next session multiply by 2 if the answer were incorrect or divide by 2, if the answer were correct. There is a limit in the maximum and minimum probabilities so that the probability could not be lower than 1/16 its inital probability of higher than 16 times its initial probability.

Notice that modifying the probability of selecting a question that not force its selection. Any question can appear in a test, but those failed previously has higher probibility. The number of actual repetitions depends on the relative size of the potential item bank and the number of question in a test session.

Here is an example of a spaced repetition test to learn greek letters.
