Abstract
In a global world, within the context of an unprecedented climate crisis, STEM education may decisively contribute to sustainable economic growth. Within this context, Portugal has been following EU guidelines by creating programs that encourage students and teachers to envision STEM education with innovative methodologies. Today's schools should provide students with motivating approaches to increase their interest in enrolling STEM courses and professions. Despite all the efforts, the results are still far from the desired goals in some areas, such as electrical engineering. In this paper, an articulation program between Coimbra Institute of Engineering (ISEC), secondary schools, and a Private Social Solidarity Institution - CASPAE, being developed under the PO ISE Program, co-financed by EU, is described. The main objective of this program is to promote STEM subjects next to young students, in an interesting, experimental and interactive environment. The program proposes several experiments that are closely related to renewable energies and sustainable energy use, in which STEM knowledge is mandatory. With technical support from ISEC, a set of interactive experiments of real-world problems was developed. To make each experiment more appealing, a multidisciplinary approach was used, bringing together experts in electrical engineering, computer science, and art designers. Four experiments called "Energy Rivers", "A Breath of Wind", "Sun Flower"and "Kilometer by Kilometer"integrate a physical prototype and a simulator of a Hydroelectric Power Plant, a Photovoltaic Panel, a Wind Turbine, and an Electrical Vehicle, respectively. Each experiment is integrated into an attractive design that suggests the purpose of the experiment, enclosed in portable modules. The set of experiments will travel to schools, thus increasing the project audience target. © 2023 Fontys University of Applied Science.

Abstract
Prosumers can organize themselves in collective self-consumption (CSC) structures and renewable energy communities (RECs) to share energy they produce locally. In addition, through their contracted balancing responsible party (BRP), i.e., retailer and aggregator, they could become flexibility providers for system services to solve, for example, local grid constraints. Since CSC and REC structures are progressively being regulated in many countries, local energy markets (LEMs) and local flexibility markets (LFMs) to be developed with these structures should find the way to comply with existing CSC rules to settle energy transactions and flexibility activation, both, locally and with the wholesale markets (WSMs) settlement, and the existing barriers and regulatory improvements should be identified to allow future implementations. Indeed, the integration of local and WSMs is still a matter of development, demanding innovative solutions, one of the main issues being, for example, the impact of the flexibility activation by one BRP into another BRP's expected delivery commitment in the WSM. This work proposes innovative designs for LEM and LFM based on common CSC rules of existing regulations, and a conceptual approach to integrate them together and with the WSM balancing responsibilities of the BRPs involved, identifying existing regulatory barriers. While many LEMs in the literature operate as WSMs, with future markets and delivery commitments for prosumers, we propose the use of a post-delivery LEM that can be cleared even after the delivery of energy, which strongly simplifies prosumers participation avoiding the need of these a priori unrealistic commitments. The business model, the main roles involved, and the contractual framework to connect the BRPs while allowing prosumers to freely contract the BRP of their choice for both energy supply and flexibility provision are described and can serve as a guide for future regulatory improvement of the common regulatory frameworks.

Abstract
Recently, we have been observing a significant evolution in products, machines, and manufacturing processes, towards a more digital and interoperable reality. In this sense, the power transformers sector has also been evolving to develop smart transformers for the future, capable of providing the digital capabilities to leverage new services and features that follow its entire life cycle, from the design and manufacturing to the use and dismantling/recycling. In this sense, this paper aims to present and demonstrate how an innovative digital twin platform can be used in a secure and trustable way for the enhancement of the power transformers’ performance and potential lifespan, enabling, at the same time, the promotion of new business models. A real use case is also presented to demonstrate the applicability of Asset Administration Shells (AAS) for power transformer life cycle management, as well as the use of the International Data Spaces (IDS) for the secure and trustable horizontal interoperability along with the different actors of the value chain, from the manufacturers to the power network and maintenance services companies.

Abstract
Computational thinking is a fundamental competence for the 21st century. It refers to a set of capacities and skills that can be stimulated to facilitate the teaching-learning process in a wide range of fields, including Science, Technology, Engineering and Mathematics (STEM). Experts in information technology argue that the earlier children are exposed to programming through digital platforms appropriate for their age, the easier it will be for them to assimilate their concepts in the future. This effort should be continued throughout the educational stages of children and youth to increase students' interest in pursuing STEM studies and careers. This paper describes the Scratch4All project promoted by the consortium CASPAE ( a Private Social Solidarity Institution) and Inova-Ria, with technical assistance from professors at the public higher education institution Coimbra Institute of Engineering. Scratch4All Project includes the activities Scratch on Road, Programming and Robotics Lab, and the Scratch4All Digital Platform. According to the impact assessment for the school year 2020-2021, the Scratch4All project promotes school success and true equality in access to new technologies for students in the 1st, 2nd, and 3rd cycles of elementary school, developing essential skills for their academic and professional future such as computational thinking, STEM competencies and social skills. By encouraging young girls to participate in technological projects, this project also aims to combat gender stereotypes.
