To prevent the participant from being asked the same question about a knowledge element, regardless of whether they answer correctly or not the first time, you can create question variants in a drill.
The following basic principle applies: The more variants, the better. The chance that the same question is repeated becomes smaller with the addition of each question variant. This also prevents participants from learning by recognition, and requires users to actually apply the knowledge they need to master the knowledge element.
These two forms are very suitable for a question about a definition. Other question variants may utilize different arithmetic tasks to achieve the same calculation or different situations applying the same grammar rule. By alternating question types, you also provide continuous engagement for a participant. How and why you make the different question types can be read here.
The more variants made of each question, the smaller the chance of the repetition of questions. Drills are, in principle, never 'finished', so over a longer period of time there is always a chance of repetition. Therefore, it is up to the author of a drill to control the extent to which a question can be repeated by adding variants..
Attention! Knowledge elements are never asked to the participant in the same order. Please note that knowledge elements should not be asked in a particular order, but should be autonomous. If you want to ask questions about certain phases in a process, for example, make separate drills within a course, with stories as connections between the different drills.
These questions are now placed underneath each other within a box and have become variants of each other. Unique questions are defined as the questions that are about one knowledge element. So multiple questions about the same knowledge element can be seen as one unique question. The question variants about one knowledge element are called unique questions. If you link two questions that were not placed directly below each other for linking, you change the question numbers. Pay attention to this when communicating the questions to co-authors or others.
In the same way, a question can be removed as a variant by clicking on ‘mark as non-equivalent’. The question will not be removed but will be included in the drill again as a separate question.
It is possible to link questions in a drill that participants have already built up a score in. For the combination of linked questions, the average score per user will be used. Initially, there is no difference in score after linking questions. However, linking questions does mean that less unique knowledge elements remain so that the score of the participant will increase faster when practicing. If new variants are added to existing questions and the number of questions remains the same, this will have no impact on the existing score of existing drill participants.
