Edutrivias: Web support system based on trivia for the teachinglearning process The elearning systems allow users to improve the traditional education systems granting flexibility, permanence, and synchrony. Many elearning systems are based on the use of web applications and games. A trivia quiz is a game metaphor which allows to enhance the teachinglearning process in an entertaining, constant and motivating way for students. This work presents Edutrivias, a web system created to support the teachinglearning process through trivia quizzes. Edutrivias uses the trivia quiz as an educational resource that allows positive reinforcement, monitoring, control and effective feedback of student learning. The description of the web system and an exploratory case study are presented. Preliminary results show that Edutrivias generates a positive impact on students, encouraging selflearning and supporting knowledge retention.

AITutor: Generating Tailored Remedial Questions and Answers Based on Cognitive Diagnostic Assessment Developing AIpowered intelligent tutoring systems to facilitate adaptive learning has been a hot research topic due to that these systems can provide personalized learning guidance by taking individual learneru0027s status and needs into consideration to improve their learning performance. Based on this perspective, this paper proposes a novel personalized adaptive tutoring system named AITutor, which not only incorporates the basic functions of general tutoring systems that providing adaptive course learning to learners, but also can generate tailored remedial questions and answers based on cognitive diagnostic assessment. This unique and tailored tutoring service will potentially help learners master the deficient knowledge points in a much shorter time. This paper presents the preliminary research and development in implementing such an AIpowered tutor. First, it gives the system design with the function description of main modules and the operating procedure. Second, it identifies four main research problems behind this system and proposes approaches to solve these problems in developing the AITutor.
