Improvement Process of Adaptive Questionnaires: Implementation and Early Experiences With e-valUAM

Adaptive questionnaires allow identifying the most appropriate question at a particular moment during an evaluation process. There are several approaches to implement adaptive questionnaires, but not many to ensure their quality. This paper shows a procedure to improve the adaptive questionnaires quality by considering the relevance of each question. Therefore, a level is associated with each question, which allows analyzing the students' answers in order to identify how to improve the evaluation process. The proposed method has been implemented in e-valUAM that allows building adaptive questionnaires and has enabled carrying out the first experiments to validate the approach.
