In this work, we propose the utilization of augmented reality (AR) in a Smart Classroom (SaCI). The architecture of a SaCI has been proposed in a previous work, based on the paradigm of multi-agent systems. In this paper, we propose an agent that provides services of AR to display and design, among other things, augmented scenarios. In addition, we define an experimental real environment in SaCI to evaluate the utilization and impact of AR in it. The results are promising, since the criteria of motivation, learning curve and memorization of the students are substantially improved in the experimental group.

The aim of this research is to develop a prototype of a multi-agent systems (MAS), which manages the resources and activities in a smart classroom (SaCI). We developed three specific objectives. First, we designed the architecture of the MAS that manages the resources and activities in a virtual learning environment (VLE), for which we used the related works on MAS in a VLE. Second, we implement the architecture of the MAS, the prototype proposed has been called GREAC (Gestion de Recursos y Actividades), which considers the learning style (LS) of the student to manage the resources and activities in an adaptive way, and uses the methodology Prometheus, Moodle 3.6 (VLE), and the framework Jade, for the development of the prototype of the MAS. Third, we evaluated the prototype GREAC in a SaCI in an academic context. In the evaluation participated 54 students from the Universidad Nacional de Loja, of the Carrera de Ingenieria en Sistemas. As a result of the evaluation by the students, we obtained a level of satisfaction 92.6 %. Finally, this work concludes that the implementation of a MAS in a VLE allows the dynamic management of resources and activities, taking into account the students LS, allowing an adaptive and personalized management.

The aim of this paper is to present a heuristic study about the level of usability of 24 universities Web portals using data mining techniques. For experimenting in this work, we used a System for Evaluation of Usability of Web sites (SIRIUS) which contains a tool to generate usability valuations of Web sites called Prometheus and integrates 10 heuristics to do the process. The assessments collected will give feedback to IT departments to redesign, restructure or implement new Web portals that comply with the standards of usability.

Artificial Intelligence (AI) is successfully intervening in areas such as education, health and industry. In education, AI is being used to improve educational processes. UNESCO considers as a new vision to involve AI not only as a didactic medium, but also as a science in which children can develop their intellect, through workshops, courses and curricula focused on the fundamentals of AI, allowing them to develop skills such as computational thinking and critical thinking. The present Systematic Literature Review was developed according to the methodological guidelines proposed by Barbara Kitchenham, with the objective of identifying how AI teaching-learning processes are carried out from early ages. Sixty-four studies were obtained between 2016-2021, where eleven countries are identified with AI teaching initiatives, through workshops, courses and projects to update their curricula; machine learning and educational robotics are the two branches linked to AI that are currently taught to children and adolescents.
