Résumé
Les méthodes permettant de détecter les réponses au hasard dans l’évaluation des apprentissages présentent quelques limites. Par exemple, les indices de détection de patrons de réponses inappropriés (person-fit indexes) nécessitent généralement d’énormes bases de données et permettent seulement de dire si un étudiant répond en accord ou non avec un modèle de mesure (par exemple, le modèle de Rasch). Dans le cadre de cet article, nous présentons une nouvelle approche permettant d’identifier les étudiants qui répondent au hasard lors d’épreuves d’évaluation des apprentissages. Après avoir discuté des limites des principales approches existantes, nous exposons les détails techniques de l’utilisation du facteur de Bayes pour évaluer un nombre fini d’hypothèses informatives. Ensuite, nous appliquons le facteur de Bayes à des données simulées et des données réelles obtenues à des fins d’illustration. Les résultats permettent de voir que le facteur de Bayes est une méthode prometteuse pour détecter le comportement de réponse au hasard.

Abstract
The available methods that permit detecting students who guess at random in learning assessment tests present many limits. For example, person-fit indexes need generally large data matrices and can be used only to detect if a student responds in accordance to a measurement model (e.g., Rasch models).
In this paper, we will present a new approach to identify students who guess at random in learning assessment tests. After discussing limits of some existing methods, we will expose the technical details of the use of the Bayes factor to evaluate a number of informative hypotheses (Hoijtink, 2012 ; Hoijtink, Klugkist and Boelen, 2008). Next, we will apply this Bayes factor to a simulation study and real data sets for illustration purposes. Our result shows that the Bayes factor is a promising way to detect students who guess at random in learning assessment tests.

Resumen
Los métodos que permiten detectar las respuestas dadas al azar en la evaluación de aprendizajes presentan algunos límites. Por ejemplo, los índices de detección de patrones de respuestas inapropiadas (person-fit indexes) necesitan generalmente grandes bases de datos y solamente permiten decir si un estudiante responde de acuerdo o no con un modelo de medida (por ejemplo, el modelo de Rasch).
En este artículo presentamos un nuevo enfoque que permite identificar a los estudiantes que responden al azar en las pruebas de evaluación de aprendizajes. Después de discutir los límites de los principales enfoques existentes, exponemos los detalles técnicos de la utilización del factor de Bayes para evaluar un número finito de hipótesis informativas. Posteriormente, aplicamos el factor de Bayes a datos simulados y a datos reales obtenidos para fines de ilustración. Los resultados permiten ver que el factor de Bayes es un método prometedor para detectar el comportamiento de respuesta aleatoria.
