Researchers in the Information Systems (IS) field have put considerable effort on identifying how personality affects technology acceptance. This study is a further step towards this direction within the context of Computer Based Assessment (CBA). Particularly, it investigates how the five personality factors affect the most important variables regarding(More)

—Empathetic behavior has been suggested to be one effective way for Embodied Conversational Agents (ECAs) to provide feedback to learners' emotions. An issue that has been raised is the effective integration of parallel and reactive empathy. The aim of this study is to examine the impact of ECAs' emotional facial and tone of voice expressions combined with(More)
Emotions are very important during learning and self-assessment procedures. Measuring emotions is a very demanding task. Several tools have been developed and used for this purpose. In this paper we evaluate the efficiency of the FaceReader during a self - assessment test. We compared instant measurements of the FaceReader with the researchers' estimations(More)

—Individual emotions play a crucial role during any learning interaction. Identifying a student's emotional state and providing personalized feedback, based on integrated pedagogical models, has been considered to be one of the main limits of traditional tools of e-learning. This paper presents an empirical study that illustrates how learner mood may be(More)
Student's emotional state is crucial during learning. When a student is in a very negative mood, learning is unlikely to occur. On the other hand too positive mood can also impair learning. Thus a key issue for instructional technology is to recognize student's mood, so as to be able to provide appropriate feedback. This paper introduces a model of(More)
The Information Systems (IS) community has put considerable effort on identifying constructs that may explain the initial/continuance use of computer based learning or assessment systems. This study is a further step toward IS continuance acceptance delivered in Computer Based Assessment (CBA) context. Specifically, it aims at the exploration of continuance(More)
