A problemática centra-se nos desafios enfrentados pelos professores para incorporar estratégias formativas, como a oferta de feedback contínuo, em contextos marcados por culturas avaliativas tradicionais. O objetivo foi analisar concepções, estratégias e obstáculos relatados por professores da rede municipal de Fortaleza (CE). A pesquisa, de abordagem qualitativa e caráter descritivo, utilizou um questionário on-line composto por seis questões, aplicado a um grupo de cinco docentes, cujas respostas foram analisadas mediante a Sequência Fedathi como Metodologia de Análise de Dados (SFMAD). Os resultados revelam predominância da avaliação formativa (80% dos professores a utilizam), embora com ênfase em aspectos comportamentais e desafios como carga horária extensa (60%) e engajamento dos alunos (40%). Conclui-se que, apesar da adoção, persistem divergências conceituais e barreiras práticas./This study investigates teaching practices and perceptions regarding formative assessment in Mathematics education during the final years of Elementary School, highlighting the gap between theoretical assumptions and their classroom implementation. The core issue focuses on the challenges teachers face in incorporating formative strategies, such as providing continuous feedback, within contexts dominated by traditional assessment cultures. The objective was to analyze the conceptions, strategies, and obstacles reported by teachers in the municipal school system of Fortaleza (CE). The research, adopting a qualitative and descriptive approach, used an online questionnaire composed of six questions, administered to a group of five teachers. Their responses were analyzed using the Fedathi Sequence as a Data Analysis Methodology (FSDAM). The results reveal a predominance of formative assessment (80% of teachers use it), though with an emphasis on behavioral aspects and challenges such as heavy workloads (60%) and student engagement (40%). The conclusion indicates that, despite its adoption, conceptual discrepancies and practical barriers persist. 2025-01-01T00:00:00Z http://hdl.handle.net/10174/41262 Title: HealthyW8: Evaluation of health parameters related to obesity prevention through saliva Authors: Mendes, C.; Silva, R.; Pérez-Jiménez, M.; Madeira, F.; Bengalinha, S.; Capela e Silva, F.; Batalha, N.; Raimundo, A.; Tavares, S.; Lamy, E. Abstract: HealthyW8 (https://www.healthyw8.eu/) is a European initiative focused on promoting sustainable lifestyle changes, with the aim of supporting individuals in the adoption and long-term maintenance of healthy habits in vulnerable stages of life. This multidisciplinary project integrates behavioral science, digital health tools, and the monitoring of biological markers to better understand how lifestyle modifications influence health trajectories in real-world contexts. Within the scope of this project, the use of non-invasive methods for collecting biological samples proves particularly relevance for assessing physiological changes associated with shifts in daily behaviors. Among the available biofluids, saliva stands out as a valuable and still underexplored matrix, offering several advantages: it is easy to collect, non-invasive, and contains numerous analytes that reflect both local and systemic physiological processes. These include inflammatory responses, oxidative stress, enzymatic activity, and proteomic alterations related to metabolic status and general well-being. This preliminary study, in the context of HealthyW8 project, aims to assess the relationship between salivary protein profile and physical activity parameters, as well as to assess the changes in this profile induced by acute practice of exercise, in children. Saliva samples are collected at two distinct time points — before and after 45 minutes exercise. The application of targeted proteomic and enzymatic analyses, allow to identify the main salivary protein components related with physical activity, in children. This is a starting point for the tasks, considered in HealthyW8 projects, where the feasibility of integrating salivary analysis into broader digital strategies for public health promotion is explored. This research is funded by the European Union through the project “Horizon-Europe (HORIZON-HLTH-STAYHLTH-01-05-twostage)”. 2025-09-11T23:00:00Z http://hdl.handle.net/10174/40856 Title: Why Public Perceptions Matter for Policies on Invasive Alien Species in Aquatic Environments Authors: Banha, Filipe; Diniz, António M.; Anastácio, Pedro; Oliva Paterna, Francisco J. Abstract: Effective management of Invasive Alien Species (IAS) requires a strong focus on social dimensions, as humans are both contributors to and potential solvers of the problem. Despite this, only a small portion of research on biological invasions addresses the human and societal aspects. This study, developed under the EU LIFE INVASAQUA project, used social science tools to explore public perceptions of IAS impacts in freshwater and estuarine ecosystems across the Iberian Peninsula, while also assessing the cultural and gender equivalence of a newly developed awareness survey. Results revealed that people perceive IAS impacts through two main lenses: an environmental domain (focused on biodiversity) and a societal domain (including socio-economic and human health aspects). However, this contrasts with how EU policies distinguish and regulate these areas, revealing a mismatch between public understanding and legislative frameworks. Differences in IAS awareness were observed between countries (Portugal and Spain), stakeholder groups, genders, and education levels. Country of origin was the strongest predictor of awareness, followed by education on biodiversity and socio-economic impacts, and stakeholder group for human health concerns. While the concept of IAS is generally well understood, with correct examples frequently cited, awareness of socio-economic and health impacts remains notably lower than that of biodiversity impacts. Perceptions of predation impacts were consistent across countries and groups, but other aspects varied. Interestingly, recreational angling was recognized both as negatively affected by IAS and as benefiting from species introductions. This study highlights the need for tailored awareness campaigns targeting specific social groups and underlines the importance of emphasizing the often-overlooked socio-economic and health impacts of IAS. Social science tools prove essential for validating survey instruments and ensuring alignment between public perceptions and policy design. Pre-legislative studies like this are crucial for bridging conceptual gaps and for better integrating the human dimension into IAS management strategies. 2025-01-01T00:00:00Z http://hdl.handle.net/10174/39144 Title: Antecedents of Psychological Capital (PsyCap): The Role of Technical and Social Variables Authors: Badotti, Sofia; Viseu, João; Bosch, José; dos Santos, Nuno Rebelo Abstract: This study aimed to identify the technical (role conflict and role ambiguity) and social (supervisor support and perceived organizational justice) antecedents of psychological capital (PsyCap). 2025-04-30T23:00:00Z
