“…To achieve quality in adaptive education, it is important to study the instruments that are applied to avoid bias in the measurement of learning styles [15]; for which, it was proposed to determine the accuracy of the learning style instruments and with a sample of 150 students. In the first place, a new learning style instrument was developed with the use of figures, graphs and equations [6]- [9], [11], [14]; which was applied, and then the same was done with the VARK instrument. In addition, the results of both were compared, determining that in the preferred learning styles of the students, there were significant differences; therefore, the alternative hypothesis was confirmed, which indicates that using different forms of information; As it is, visual and active content to build learning style instruments have a significant impact on the measurement of learning preferences.…”
