User Model

The user model is the youngest component of the VILAB system. It manages and stores information about students in a database. The data are used for the generation of adaptive feedback to help the student solve the task at hand.

Which data are stored?

Inside the lab different types of user data are acquired and used:

• Multiple-choice answers to get information about his previous knowledge with respect to the topic of the given lab station
• Multiple-choice answers to get information about the learning type of the student
• Information about the number of tries the user needs to solve a task
• Which tasks have already been solved by a student.

How are they used?

The data are used to generate a feedback which helps the user to proceed with his tasks without being annoyed by too much feedback or feeling left alone with too little help.
