This questionnaire allows you to obtain essential information about your participants (age, gender, etc.).

The various criteria assessed through this questionnaire are traditional criteria for population segmentation.

In the case where you are targeting a specific population, these indicators will help you determine if your participants are a good fit for your target sample.
These pieces of information also enable you to verify that your sample is representative of the overall population.

If you wish to study different groups of participants, socio-demographic data allows you to create your various conditions.

Cette échelle est une extension de l'échelle de charge cognitive (CLS) de Leppink et al. (2013).
Elle permet de mesurer les trois types de charges cognitives (intrinsèque, extrinsèque et essentielle) dans un contexte d'apprentissage en environnement virtuel.

Plus précisément, la dimension "charge extrinsèque" de la CLS est divisée en trois sous-échelles :

- Charge extrinsèque relative à l'instruction
- Charge extrinsèque relative à l'interaction
- Charge extrinsèque relative à l'environnement

This questionnaire provides feedback from participants on the system they have used. This tool helps to understand which aspects of the system are problematic and which aspects meet the user's needs.

For the rating, a Likert scale of 1 to 7 is used from1 = Strongly agree to 7 = Strongly disagree.

Scoring: The CSUQ scores are grouped into five categories:
- an overall score, which combines items from 1 to 16, i.e. all items
- a system utility score (SysUse), which combines items 1-6
- a score on the quality of information (InfoQual), which combines items from 7 to 12
- a score on the quality of the interface (IntQual), which gathers items from 13 to 15
- a score on general satisfaction (item 16)
