These environments allow students to access content, complete activities, and interact with peers and instructors in a flexible and personalized manner. In this scenario, Self-Regulated Learning stands out as a key com- petency, as it enables learners to autonomously manage, monitor, and direct their own learning process. This study proposes and validates an Artificial Intelligence - supported Pedagogical Architecture to foster SRL in VLEs, aiming to enhance students’ autonomy and engagement. Initially, a systematic literature review was conducted, which identified research gaps and guided the PA design. Subsequently, Proofs of Concept were carried out using data from the Open University Learning Analytics Dataset and from Moodle at IFSULDEMINAS – Campus Carmo de Minas, applying Educational Data Mining tech- niques and clustering algorithms. These analyzes allowed the identification of behavioral patterns, SRL profiles, and significant correlations between engagement and academic performance. In the final stage, the PA was implemented and evaluated in the context of an online Introduction to Python Programming course. Among the resources integrated into the VLE, the Time Tracker SRL plugin stands out, developed to monitor the time dedicated to learning activities and provide automated feedback. Other plugins, such as Configure Reports, Completion Progress, Analytics Graphs, and OpenAI Chat, were also employed to support the self-regulation process. The results showed that the PA had a significant impact in promoting SRL, with a positive correlation between engagement and academic performance. The triangulation of evidence—based on VLE log analysis, self-regulation questionnaires, and focus group interviews—confirmed the effectiveness of the PA, validating its potential to develop SRL skills, foster autonomy, and improve stu- dent performance. Thus, the proposed approach constitutes an innovative, scalable, and adaptable solution to support and personalize learning in VLEs.

Current applications impose new demands on the network that it cannot meet, given its limitations. One of the difficulties of the Internet is the lack of flexibility to deploy new network-layer services, which limits its evolution. This scenario motivated the development of several Future Internet Architectures (FIAs). These are disjoint architectures that propose, through their designs, to offer mechanisms that advance various aspects of communication, such as flexibility in the network layer, mobility, multicasting, quality of service (QoS), connectivity, quality of experience (QoE), security, among others. Despite the demand, the lack of implementation of these new architectures in high-performance networks makes it difficult to assess the maturity of their communication characteristics for specific scenarios and applications. On the other hand, due to the ubiquity of the traditional Internet, replacing the TCP/IP architecture is impractical. A single communication network or logical exchange point that integrates FIAs and the TCP/IP architecture without compromising its architectural principles (resources and mechanisms) is a promising approach to meeting the demands of current and future applications. This work presents the Future Internet Exchange Point (FIXP) and positions it as a candidate for this single network or logical exchange point that allows the coexistence of different Internet architectures; it also provides qualitative and quantitative analysis of FIXP: its capacity for evolution and incorporation of new architectures, the feasibility of implementing FIXP in the current networks, and the performance of application communication of IP and ETArch architectures in the FIXP infrastructure, taking into account the quality of user experience. Evaluations demonstrate the FIXP architecture conceptually by executing selected use cases in which applications from different FIAs coexist in the same communication environment. In addition, the work presents the details of the integration of the ETArch and IP architectures in the FIXP network, aiming to facilitate, in the future, the incorporation of other Internet architectures in this infrastructure. Regarding related work, the collection allows comparison with these works and with FIXP, positioning it as the state of the art, as the only infrastructure that does not add overhead to switching devices through interoperability processes and/or protocol stack development. Furthermore, its architectural principles differ from those of related work; therefore, the difficulty of integrating new FIAs into FIXP is low to medium relative to that of related work. These two facts, the lack of data plan overhead and the low or medium difficulty level of integrating new FIAs, facilitate the implementation of FIXP in current networks. The work also presents FIXP’s view of multi-architecture applications. These applications use different Internet architectures for their services. The use cases that demonstrate FIXP’s support for these applications simulate the execution of microservices within the same application or virtual machine, which is common nowadays. The difference is that microservices in a multi-architecture application can use frameworks from different FIAs.
