In this paper we explore the importance of analyzing the exercises that the manuals have in Mathematics study, because the difficulty of identifying some errors on them can interfere with the capabilities of children. We work with some exercises related to the theme of temporal notions, based on a survey of textbooks from the 1st and 2nd grade (K-1 and K-2). Our concern is to alert about the importance of reflecting on the content of the books, in order to promote a teaching-learning process tailored to the needs of children. The activities present in the manuals should allow children to develop their logical- mathematical reasoning, for later be able to understand and apply Mathematics. To this end, we present some reflection about the exercises of manuals, and we give our opinion about what is the correct and incorrect. Also, some activities are suggested, among which were implemented with children of the 2nd grade, K- 2, along the experiments that support our work.

On this work we suggest a teaching solution that can be implemented in Azores, an archipelago of nine islands of Portugal, based in already known system of e-learning, with a twist based on the flipped method. Structured in a cooperative way, the organization of the system allows to isolated groups of people to have access to a certain level of teaching, if they cannot have the possibility to have physical presence in school due to problems emerging from territory discontinuity. Our suggestion can be elaborate in a model that can be adapted to any level of education, and can be adapted also in cases that a cut of budget exists. We suggest the name of fb-learning: Flipped Broadcast Learning.

A resolução de problemas é um processo fundamental na aprendizagem da matemática. Neste artigo, apresenta-se uma reflexão sobre a importância deste processo matemático e de como ele pode ser conduzido de forma a estimular o raciocínio matemático através da promoção da comunicação, em contexto de sala de aula. O trabalho foi realizado na etapa final de formação de educadores e professores no contexto do pré-escolar e do primeiro ciclo do ensino básico. Em resultado das atividades realizadas, discute-se o papel da utilização de uma heurística ao longo da resolução de problemas, a importância na escolha de estratégia para a interação com os alunos, bem como o desenho intencional de materiais didáticos. A experiência enquadra-se numa abordagem qualitativa de design de experiência de ensino.

Mathematical literacy in Portugal is very unsatisfactory in what concerns international standards. Even more disturbingly, the Azores archipelago ranks as one of the worst regions of Portugal in this respect. We reason that the popularisation of Mathematics through interactive exhibitions and activities can contribute actively to disseminate mathematical knowledge, increase awareness of the importance of Mathematics in today’s world and change its negative perception by the majority of the citizens. Although a significant investment has been undertaken by the local regional government in creating several science centres for the popularisation of Science, there is no centre for the popularisation of Mathematics. We present our first steps towards bringing Mathematics to unconventional settings by means of hands-on activities. We describe in some detail three activities. One activity has to do with applying trigonometry to measure distances in Astronomy, which can also be applied to Earth objects. Another activity concerns the presence of numerical patterns in the Azorean flora. The third activity explores geometrical patterns in the Azorean cultural heritage. It is our understanding that the implementation of these and other easy-to-follow and challenging activities will contribute to the awareness of the importance and beauty of Mathematics.

No presente artigo discutem-se conceitos relacionados com a aprendizagem e a avaliação da comunicação oral e escrita, considerando os domínios linguísticos da fonologia, sintaxe, semântica e pragmática. Discutem-se, ainda, algumas variáveis sócio-cognitivas, como o locus de controlo e as atribuições causais, a motivação para o sucesso e para o desânimo, o auto-conceito e a auto-eficácia, que têm evidenciado relação com a educação escolar. A partir desta discussão, apresentam-se alguns itens susceptíveis de virem a contribuir para a construção de instrumentos de avaliação do funcionamento do aluno.

Existe a ideia generalizada de que a indisciplina escolar tem vindo a aumentar e, em alguns casos, a evoluir para situações de violência. Neste artigo procura-se compreender a difusão dessa ideia à luz do enquadramento só-cio-político vivido em Portugal desde o último quartil do século XX, apresenta-se o início das preocupações e das investigações portuguesas sobre o tema, numa perspectiva preventiva e pedagógica, e partilham-se alguns dados sobre investigações empíricas realizadas em S. Miguel, nos Açores. No âmbito destas, procura-se desvendar o que pensam professores e alunos acerca da indisciplina escolar e, por fim, emergente dos dados, propõe-se uma tipologia de procedimentos adoptados pelos professores para lidar com a indisciplina dos alunos.

Present study aims to describe records of mauled and con-specific injures in various fish inhabiting different environment and to discuss possible impacts on fish behavior and ontogenesis. The fish specimens were collected from the Black Sea and Azores Islands (NE Atlantic). Individuals of European flounder, Pleuronectes flesus, common stingray, Dasyatis pastinaca and turbot, Scophthalmus maximus with missing dorsal and caudal fins and flesh, were found in the Black Sea. Specimens with severe mauls of the ocean sunfish, Mola mola, almaco jack, Seriola rivoliana and sargo, Diplodus sargus were recorded from the Azores Islands. All of them were caught alive and survived severe mauls caused by predators or by accidents with propellers, fishing nets. The NE Atlantic records, although possibly caused by natural predation, are more probably than not the result of negative interactions with human activity. Numerous records of mauled fish species from both regions show that the problem with adverse effects of fisheries is quite important. Predatory and con-specific injuries obviously are compatible with basic fish vital functions of described cases. The problem with negative anthropogenic interactions seems to be insufficiently investigated and need more attention by responsible managers and decision makers.

Tourism contributes to the development of many regions. Different factors affect the movement of tourists within a destination. Those factors are related to the tourist characteristics, like the time budgets, preferences or destination knowledge, and to the destination features, like the attraction characteristics or accessibility level. Tourist decisions aren’t always done in a rational way. Emotions add further complexity to the human decision process. The use of footpaths can play an important role in the satisfaction of tourists, helping them discover the territory and giving them access to different types of attractions. The existence of a mathematical model that integrates the main factors related to the movement of independent tourists within a destination, in a dynamic way, will make possible the creation of an adaptable software tool. This tool will meet the specific needs of tourists, allowing the use of the network in an optimal way by the different tourist profiles, and the needs of the regional government and business, permitting better decisions and the offer of relevant tourism products. This article identifies the main tourists’ mobility criteria in the São Miguel island territory, Azores, Portugal, recognizes the necessary modelling process and identifies the basis for the construction of the mathematical model that explains the movement of tourists within the destination.

Not a year goes by that we don't hear of another hazing scandal in a higher education institution. Many researchers took interest in this issue in order to understand its causes and consequences. They provided definitions and lead to prevent it. We found hazing in many social groups around the world, with different names, and under specific forms. This paper aims to better understand hazing and its actors, with a specific focus on hazing in higher education. We presented three definitions to offer several perspectives on hazing, and facilitate its apprehension. Our method was to analyze the relevant scientific literature with the intention of reflecting on its roots and representation among individuals. Results are an exposition of motivations from hazing's actors, recommendations about how to define it and how to prevent derivations. Our main conclusions assume hazing is usually depicted as a deviant behavior, but it would appear to be a norm. Also, its core purpose would be the progression from newcomer to a group member. A lack of structure or meaning could lead to its misuse and facilitate outrageous events. In higher education, hazing seems to be used as a tool to integrate freshmen in their new institutional world. Scandals including violence, sexual and alcohol abuse could be a symptom of something deeper from hazing's environment.

In the business world, employees can contribute with information, ideas, concerns, opinions and proposals to their managers in respect of: (1) the way work could be performed, (2) what should / should not be done in the workplace, (3) how a particular decision can be implemented, and (4) how an organizational policy should be formed and executed (Rego, 2013). However, due to a diverse set of factors, employees often choose to remain silent in the workplace. One of these factors is psychological safety, which describes employees’ perceptions of the consequences of taking interpersonal risks in the workplace (Edmondson, 2014). The following paper is essentially a literature review and its aim is to, firstly, make a brief approach to factors reported in the literature that may affect employee voice and silence, followed up by an explanation of the types of silence that can be engaged by employees. Besides that, the authors will also make an approach to physical and psychological safety. Lastly, it will be reported some links, mentioned in the literature, between employee silence and psychological safety.
