Stepping up from an experienced teacher to a lesson study facilitator
Publication . Gomes, Paula; Martins, Micaela; Quaresma, Marisa; Rodrigues, Bruna; Ponte, João Pedro da
In this paper, we aim to understand how an experienced teacher, Vanda, who had already participated in two LS, has an initial experience as a lesson study facilitator. She was challenged to facilitate LS by a more experienced facilitator, who was alongside with her all the LS sessions. The two facilitators worked collaboratively to prepare the LS. Data collection included participant observation, with audio recordings of the preparation and LS sessions, and audio recordings of semistructured interviews before and after the LS and included document collection. The results show how the dimensions of resources, orientations, goals and identity (ROGI framework) interplay in framing Vanda's concerns and practices as a novice facilitator.
Necessary skills and knowledge and challenges of the mathematics lesson study facilitator: aliterature review
Publication . Quaresma, Marisa; Martins, Micaela; Gomes, Paula; Rodrigues, Bruna; Ponte, João Pedro da
In lesson studies carried out in Western countries, a key role is played by the facilitator, who organizes and leads the entire process. Despite the contributions regarding this issue provided in the literature, the knowledge about the preparation that facilitators need and the challenges that they face in their activity is still fragmented. Thus, the aim of this communication is to present a systematic literature review on the role of the facilitator in lesson studies in mathematics, identifying and synthesizing the necessary skills and knowledge and the challenges faced by facilitators and suggesting directions for future research.
Investigating the use of large-diameter earth–air Heat exchangers to achieve office building cooling self-sufficiency
Publication . Duarte, Rogério; Rebola, Amândio; Coelho, Luís
Standalone use of EAHEs for room cooling is a passive and nature-based alternative to air conditioning technology that can be used to mitigate the increase in electricity and
GWP-refrigerant consumption associated with cooling in buildings. EAHEs replacing air conditioning is documented in the technical and research literature. However, for
office-room cooling, EAHEs are mostly employed as a support to air conditioning systems for precooling outdoor air. The larger cooling loads and the stricter design conditions
commonly used in the sizing of office rooms prevent the most commonly investigated EAHE typologies from operating effectively in standalone cooling mode. To assess the
feasibility of alternative typologies, such as large-diameter EAHEs, tools that are capable of modeling the complexity of the coupled heat and moisture transfer between air and soil
are particularly valuable. For detailed assessments, researchers typically turn to advanced commercial tools; however, developments in free and open-source scientific programming languages that combine symbolic computation packages with efficient numerical solvers of partial differential equations allow analyses at reduced cost that are comparable to those from commercial tools. This paper shows how one such programming language can be used to study the coupled heat and moisture transfer problem in EAHEs. Starting from the symbolic form of the mathematical problem, the numerical implementation is described and validated with monitoring data from an existing large-diameter EAHE. Using the validated computational model, the paper proceeds to study the sensitivity of load removal in EAHEs operating in standalone and precooling cooling modes, highlighting fundamental differences between both operating modes, identifying the most relevant design parameters and providing guidance on the conditions under which an EAHE enables self-sufficient cooling of office buildings. The results show how, for a hot and dry climate, standalone EAHEs with large diameters (∼1 m), buried at depths larger than 3 m, allow the removal of up to 20 kWh/m2 of room sensible cooling loads, a level that is consistent with the cooling demand of low-energy office buildings.
Bridging the Gap
Publication . Frias, A.; Água, Pedro B.; Conceição, Vitor; Silva, Miguel Nuno Machado da
This study aims to critically analyse the evolution of Maritime Education and Training (MET), proposing solutions to fill the gap between theoretical training and operational practice. In the current context of increasingly complex, digitalised and automated socio-technical systems onboard, MET has shifted from traditional onboard situated learning models to more formalised and standardised approaches, such as decontextualised learning in the classroom. However, the current education system is often associated with limitations in the development of non-technical and adaptive skills. Methodologically, this study takes a historical-prospective approach, drawing on a critical review of scientific literature and relevant international regulatory frameworks. The results demonstrate that active learning methodologies supported by immersive technologies, such as simulation, virtual reality, and augmented reality, can significantly strengthen the connection between theory and practice in safe, controlled environments. Therefore, the study proposes a competency-based hybrid model of education and training that integrates theoretical teaching, immersive simulation and supervised onboard experience. The study concludes that the evolution of MET should be based on an integrated, contextualised pedagogical approach that aligns with contemporary demands in the maritime sector.
Leadership as a performance multiplier of logistics operations in VUCA environments
Publication . Frias, A.; Silva, Miguel Nuno Machado da; Soares, Ivo; Água, Pedro B.
This article aims to analyze the role of leadership as a performance multiplier in military logistics operations within VUCA environments. Although logistics are usually viewed through technical and procedural lenses, research suggests that performance stems from the interaction of organizational, human, and decision-making factors, especially in contexts of high uncertainty and interdependence. Methodologically, this study employs a narrative review of scientific literature, complemented by a conceptual analysis, to identify causal mechanisms and critical leadership skills. The results demonstrate that leadership influences logistics execution through practices such as prioritization, network coordination, risk management, and fostering a culture of discipline and learning. Additionally, leadership shapes organizational mediators such as information quality, flow coherence, and adaptability. The study presents a conceptual leadership model for logistics performance. It concludes that leadership is a critical factor in logistics effectiveness and essential to the reliability, resilience, and readiness of forces. Therefore, leadership should be included in the training of logistics professionals and in logistics doctrine.
