Analysis of CHAEA: Contributions from the Item Response Theory and the Impact Method
Journal Title: PARIPEX-Indian Journal of Research - Year 2017, Vol 6, Issue 8
Abstract
During the last years, the concept of learning styles has generated numerous questions in academic field. In spite of the great variety of instruments that exist, the Honey-Alonso Learning Styles Questionnaire (CHAEA) has been consolidated as one of the most used to know learning styles of Spanish-speaking students. In this paper, we analyse CHAEA in order to better understand its psychometric characteristics. Specifically, we use Item Response Theory (IRT) and Impact Method. We found that some items could be remove from the scale and it would have practically the same information capacity. In addition, the impact method of CHAEA items showed the items of each dimension with the highest impact coincide with the items that provide sufficient information through the IRT. It is concluded that the combined application of IRT and Impact methods can contribute significantly to the analysis of the psychometric tests.
