Matemática comercial e financeira com a utilização de recursos digitais: uma experiência no ensino médio

This work aimed to investigate the possible contributions of the use of digital resources in the teaching and learning process of Commercial and Financial Mathematics concepts to high school students. Its development has included a survey of some researches on the topic as well as an experimental study of a qualitative type, in which the Webquest was used as methodology. It uses the computer, more precisely the internet resources, to assist students in building up knowledge. Eight meetings were held, in the after-school period, with a group of students of the second year of high school at a state public school in the city of Guaratinguetá. Aiming to evaluate the knowledge that students had about the theme, it was applied a diagnosis at first glance for further analysis and development of activities and interventions according to the students’ answers. Once the research data was analyzed, it was noted that the students had little knowledge regarding the basic contents of Commercial and Financial Mathematics, in addition to presenting difficulties in handling some of the digital resources used in the meetings. Nonetheless, from the students’ works, it was seen significant advances in understanding and building up knowledge on concepts such as percentage, simple and compound interest, savings, and sales involving prompt payment or in arrears

A Inversão das distâncias: do som do corpo ao corpo do som

This essay deals with the relationship between the body of the composer and his sounds, approaching - by a philosophical point of view - the process of objectivation of sound along the history of musical writing (escritura = musical scripture), until coming up the emergence of electroacoustic music. At this point, the text handles with the dialectic between analogical and digital resources and with the most crucial problems of electroacoustic music in our days.

Overview of international research in generic competence assessment

The competency assessment is a key issue for improving the quality of teaching and learning within the current European Higher Education Area (EHEA). The aim of this paper is to review the current research on assessment of generic competences, especially through online tools. It has conducted a search of the Web of Knowledge (Thomson Reuters) from keywords. It have been reviewed the abstracts and the results have been classified by time periods, countries and research area. It has selected a set of articles of the period 2010?2012, in which we have analyzed future trends. It is concluded that the research of assessment generic competences is been developing nowadays in educational area, although is still more important in the professional one. Additionally, it is surprising that appears most often used in preuniversity education levels. The academic context has increased research activities over the past five years, with different developments in the Anglo?Saxon countries over that those countries attached to the Bologna Process. The latest reports indicate that the learning competences must meet the individual reality of each person, so that the use of ICTs in their development and evaluation are essential given its immediacy and motivational ability. There is a clear trend towards an evaluation model that includes a 360º specific and generic competences analysis.

El pensamiento creativo de Fernando Higueras

Para acercarnos al pensamiento creativo de Fernando Higueras como arquitecto, partimos del estudio de sus constantes creativas en evolución cronológica divididas en 9 direcciones de investigación. En ellas observamos la importancia de su obra NO CONSTRUIDA, como germen de las constantes creativas de su pensamiento y parte de ella la estudiamos, analizamos y reconstruimos gráficamente en 3D. Fernando Higueras aprendía de sus obras o propuestas arquitectónicas anteriores llegando a la madurez constructiva y formal colmada de Belleza a través de la composición y combinación de dichas constantes con pasmosa naturalidad. Además es importante añadir, para llegar a la comprensión de las constantes del pensamiento creativo del arquitecto, el componente de “intuición” de todo artista, de su modo de mirar y observar las cosas como fuente de inspiración. El “modo de mirar” del arquitecto nos habla de su sensibilidad al hábitat popular y vernáculo del hombre. Gracias a Antonio Miró en el período 1963-1970, Fernando Higueras pudo dar marco real a gran parte de sus ideas constructivas. El objeto de estudio del presente trabajo es llegar a las “invariantes” del arquitecto para comprender su pensamiento creativo. Los objetivos del presente estudio han sido conocer mejor su pensamiento, su obra desde un punto de vista cronológico-evolutivo para poder llegar a entender las relaciones y conexiones creativas entre unas y otras, observar y constatar la evolución de sus constantes creativas y compositivas, de analizar gráficamente parte de su obra no construida para llegar a la mejor comprensión de dichas constantes reconstruyéndolas con los medios gráficos digitales actuales. La reconstrucción en 3D de parte de su obra no construida constata la magnitud de su pensamiento creativo. La metodología empleada parte de la recopilación de toda la información necesaria, escritos, artículos en revistas o periódicos, críticas, observaciones, planos, proyectos, memorias, fotografías de la época, maquetas, opiniones de sus contemporáneos, familiares o amigos y visita de parte de su obra construida. A partir de ahí se fijan 9 direcciones de investigación para cada constante de su pensamiento creativo. En cada dirección se analiza desde dos puntos de vista diferentes. Un primer punto de vista teórico o cronológico-evolutivo a partir de la selección de algunas de sus obras construidas y no construidas. Y otro segundo punto de vista gráfico basándose en el estudio y reconstrucción de parte de su obra no construida. En resultado, se ha estudiado la evolución de su obra viendo las conexiones y relaciones entre unas y otras llegando a la madurez de sus constantes creativas en sus obras, algunas construidas y otras no construidas. Fernando Higueras se perfecciona así mismo, intentando hacer las cosas cada vez un poco mejor, llegando a dominar sus propias constantes en total madurez y expresión formal y constructiva. La elaboración de modelos tridimensionales en 13 proyectos de su obra no construida nos refresca la capacidad de su pensamiento creativo, además de analizar en parte de ellas los gérmenes constructivos y compositivos de muchas de sus ideas o constantes creativas. Finalmente, este trabajo ha contribuido a llegar a entender a Fernando Higueras en una dimensión más amplia, desde el frescor de su obra no construida hasta la capacidad de su pensamiento creativo, de la evolución de sus constantes, del estudio de sus últimos proyectos no construidos, de su sensibilidad a todas las artes y a todo lo que engloba Belleza. Las 360 láminas de dibujos que se aportan inician el estudio y análisis de su vasta obra no construida. ABSTRACT The analysis of Fernando Higueras's creative thought as an architect begins with a study of his main creative themes and their chronological evolution, divided into nine directions of research. Here we see the importance of his UNBUILT work as the germ of the creative themes of his thought, part of which we study, analyse and reconstruct graphically in 3-D. Fernando Higueras drew on his earlier architectural works and ideas and reached an ultimate constructive and formal maturity that was infused with beauty through composition and the amazingly natural combination of these keynote themes. In order to gain a greater understanding of the key themes of the architect's creative thought it is also worth noting the element of artists' intuition, their way of seeing and observing the world as a source of inspiration. The architect's "way of seeing" reveals his sensitivity to the popular and traditional human habitat. Thanks to Antonio Miró, in the period between 1963 and 1970 Fernando Higueras was able to provide a real framework for a large part of his constructive ideas. The object of study of the present work is to determine the architect's “invariables” as a means of understanding his creative thought. The aims of the present study are to explore his thoughts in greater depth, to examine his work from the chronological-evolutionary point of view for an insight into the relationships and the creative connections between them, to observe and apprehend the evolution of his main creative themes and compositional keynotes, to analyse graphically part of his unbuilt work in order to improve our understanding of these underlying themes through their reconstruction using the latest graphic digital resources. The 3-D reconstruction of part of his unbuilt work highlights the magnitude of his creative thought. The methodology used to collect all the necessary information includes an examination of his writings and articles in journals and newspapers, criticisms, observations, plans, projects, building specifications, period photographs, models, the opinions of his contemporaries, family and friends, and visits to some of his built work. Nine directions of research were then established for each main theme of his creative thought. Each direction includes an analysis from two different points of view: the first, theoretical or chronological-evolutionary aspect, based on a selection of some of his built and unbuilt works; and a second graphic aspect based on the study and reconstruction of part of his unbuilt work. The result is a survey of the evolution of his work with a view to establishing the connections and their interrelationships, through to the ultimate maturity of his creative themes in both his built and unbuilt work. Fernando Higueras is on a constant quest for excellence, a perpetual desire to do things a little better, until a point where he gains mastery over his own recurrent themes, in the fullness of maturity and of his formal and constructive expression. The creation of three-dimensional models in 13 projects of his unbuilt work offers a new look at the capacity of his creative thought, in addition to the analysis of the evidence in some of these projects of the constructive and compositional germs of many of his ideas and themes. Finally, this work has contributed to the understanding of Fernando Higueras in a broader dimension, from the freshness of his unbuilt work through to the capacity of his creative thought, the evolution of his main themes, the study of his final unbuilt works, his sensitivity to the arts as a whole and to everything beautiful. The 360 plates of illustrations provided form the basis of the study and analysis of his extensive unbuilt work.

A framework for automated construction of resource space based on background knowledge

Resource Space Model is a kind of data model which can effectively and flexibly manage the digital resources in cyber-physical system from multidimensional and hierarchical perspectives. This paper focuses on constructing resource space automatically. We propose a framework that organizes a set of digital resources according to different semantic dimensions combining human background knowledge in WordNet and Wikipedia. The construction process includes four steps: extracting candidate keywords, building semantic graphs, detecting semantic communities and generating resource space. An unsupervised statistical language topic model (i.e., Latent Dirichlet Allocation) is applied to extract candidate keywords of the facets. To better interpret meanings of the facets found by LDA, we map the keywords to Wikipedia concepts, calculate word relatedness using WordNet's noun synsets and construct corresponding semantic graphs. Moreover, semantic communities are identified by GN algorithm. After extracting candidate axes based on Wikipedia concept hierarchy, the final axes of resource space are sorted and picked out through three different ranking strategies. The experimental results demonstrate that the proposed framework can organize resources automatically and effectively.©2013 Published by Elsevier Ltd. All rights reserved.

The Knowledge in Automotive Field Representation with Modern Technologies

Modern technologies have changed the way of presenting information in archives. This makes it possible to introduce new services, which was unimaginable a few years ago. Digitalization, security and virtual presentation of objects in the sphere of motoring by application of technologies, based on knowledge about how to create digital resources is the theme of this project. The aim of AutoKnow project is to carry out a research and create a multi- media digital archive AutoKnow and Experimental Virtual Motor Laboratory (EVML) with Motor Library (ML) from digital multi-media patterns from a selected group of objects in the sphere of automobile technology, presented by NMU.

Linking Old Librarianship to New: Aligning 5-Steps of The Innovator's DNA in Creating Thematic Discovery Systems for the Everglades

This poster presentation from the May 2015 Florida Library Association Conference, along with the Everglades Explorer discovery portal at http://ee.fiu.edu, demonstrates how traditional bibliographic and curatorial principles can be applied to: 1) selection, cross-walking and aggregation of metadata linking end-users to wide-spread digital resources from multiple silos; 2) harvesting of select PDFs, HTML and media for web archiving and access; 3) selection of CMS domains, sub-domains and folders for targeted searching using an API. Choosing content for this discovery portal is comparable to past scholarly practice of creating and publishing subject bibliographies, except metadata and data are housed in relational databases. This new and yet traditional capacity coincides with: Growth of bibliographic utilities (MarcEdit); Evolution of open-source discovery systems (eXtensible Catalog); Development of target-capable web crawling and archiving systems (Archive-it); and specialized search APIs (Google). At the same time, historical and technical changes – specifically the increasing fluidity and re-purposing of syndicated metadata – make this possible. It equally stems from the expansion of freely accessible digitized legacy and born-digital resources. Innovation principles helped frame the process by which the thematic Everglades discovery portal was created at Florida International University. The path -- to providing for more effective searching and co-location of digital scientific, educational and historical material related to the Everglades -- is contextualized through five concepts found within Dyer and Christensen’s “The Innovator’s DNA: Mastering the five skills of disruptive innovators (2011). The project also aligns with Ranganathan’s Laws of Library Science, especially the 4th Law -- to "save the time of the user.”

Recursos digitais promotores de pensamento crítico em ciências no 1º ciclo

A sociedade em que vivemos hoje encontra-se submersa pela tecnologia em todas as áreas e saberes, exigindo-se aos cidadãos a capacidade de pensar e agir racionalmente perante os desafios e problemas que vão surgindo ao longo da vida. As tecnologias da informação e comunicação (TIC) são uma presença evidente no quotidiano e diversas investigações e estudos têm vindo a enfatizar o seu potencial no processo de ensino-aprendizagem. Ademais, face aos desafios científicos e tecnológicos da nossa sociedade, é fundamental formar-se cidadãos capazes de pensar criticamente e racionalmente, de tomarem decisões focadas no que se deve fazer ou acreditar. Assim, reconhecendo a importância de se promover o pensamento crítico (PC) recorrendo-se às TIC, desenvolveu-se a presente investigação com o intuito de promover o PC dos alunos, através da exploração de diversos recursos digitais já disponíveis gratuitamente na internet. Decorrente da finalidade apresentada formularam-se as seguintes questões de estudo: (i) Quais os contributos dos recursos digitais explicitamente promotores de pensamento crítico dos alunos do 3.º ano de escolaridade?; e (ii) Quais os contributos dos recursos digitais explicitamente promotores de pensamento crítico para a construção de conhecimentos científicos, na área das Ciências, dos alunos do 3.º ano de escolaridade?. A presente investigação desenvolveu-se de acordo com um paradigma sócio-crítico, segundo uma perspetiva metodológica predominantemente qualitativa e com base num plano de Investigação-Ação. A implementação das três atividades construídas, incluindo a exploração dos recursos digitais, decorreu numa turma de 26 alunos inseridos num colégio do distrito de Aveiro, no qual se realizou a Prática Pedagógica Supervisionada da professora investigadora. Para a recolha dos dados utilizaram-se diversos instrumentos, nomeadamente testes de levantamento inicial e final das capacidades de PC, listas de verificação, diário do investigador, fichas de trabalho resolvidas pelos alunos (tendo por base a Taxonomia de Ennis) e questionários de autoavaliação do desempenho dos mesmos. Na análise de dados, privilegiou-se a análise de conteúdo recorrendo-se ao software WebQDA. Com base nos instrumentos de recolha de dados referidos verificou-se que os alunos manifestaram uma maior facilidade a responder a questões que promoviam o uso de capacidades de PC referentes à Clarificação Elementar e à Indução e uma dificuldade acentuada na dimensão das Estratégias e Táticas. No que diz respeito à construção de conhecimentos científicos, os alunos demonstraram, principalmente, dificuldades em reconhecer que o movimento é impulsionado pelas rodas dentadas e a constatar que o tamanho do fio influencia a velocidade do pêndulo. Pode-se concluir que os recursos digitais, de um modo geral, contribuíram para mobilizar o potencial de capacidades de PC e para a construção de conhecimentos científicos. O contributo deste estudo, embora modesto, prende-se com o potencial das TIC na Educação em Ciências dos 1º CEB, na promoção do pensamento crítico e de conhecimentos.

Atividades de investigação mediadas pelas TICE : estudo das conceções, interações e discussões desenvolvidas por crianças e jovens dentro de um contexto de ensino de ciências ativo e colaborativo

A temática de discussão neste trabalho é o Ensino de Ciências através da Investigação (ENCI) [inquiry-based science education (IBSE)] que utilisa das Tecnologias de Informação e Comunicação (TIC) para o ensino de Ciências (TICEC). Deste modo, esta pesquisa tem o objetivo de identificar as conceções sobre a Natureza da Ciência e Tecnologia, além de compreender as interações, relações e discussões de crianças e jovens ao realizarem atividades de investigação através das TIC, dentro de um contexto de ensino de Ciências ativo e colaborativo. Organizamos esta investigação em três partes com diferentes estudos para alcançar este objetivo. A primeira parte apresenta estudos, a partir de uma revisão sistemática, de como se ensina e aprende Ciências utilizando as TICEC. Realizamos ainda uma revisão sobre o papel da argumentação no ensino de Ciências e elaboramos um instrumento para analizar a argumentação dos participantes numa atividade investigativa baseada em TICs. A segunda parte deste trabalho caracteriza a metodologia utilizada e os elementos da investigação: aspetos metodológicos (pesquisa qualitativa e estudo de caso), cenário (espaço não-formal de ensino de ciências ativo e colaborativo), sujeitos (crianças e jovens provenientes de um meio económico vulnerável), instrumentos de coleta de dados (questionário, filmagem de entrevistas, focus group e observações) e análise de dados (sistema de categorias). Também é apresentada a elaboração de uma atividade de investigação de ensino de Ciências (AIEC) mediada por recursos digitais, denominada de Módulo Temático Virtual (MTV). A terceira parte caracteriza-se pela apresentação dos resultados. No primeiro momento identificamos as conceções dos participantes sobre a Natureza da Ciência (Nature of Science – NOS), Natureza da Tecnologia (Nature of Technology - NOT) e o papel dos cientistas na sociedade. O último estudo vem caracterizar as interações, relações e discussões desenvolvidas pelos participantes quando realizam AIEC através das TICEC. Verificamos que dentro de um contexto ativo de ensino de Ciências e mediado pelas TIC, os participantes tendem a manifestar quatro aspetos ou domínios: social, técnico, afetivo e cognitivo. Os quatros domínios referidos caracterizam os processos que surgem durante o desenvolvimento de atividades científicas num cenário específico complementar à educação tradicional e são indicadores de como planear e analisar o ensino de Ciências quando se utiliza recurso digitais.

Educational software in english to the awareness in a preschool education supervised context

Information and communication technologies play an increasingly important role in society, in the sense that all areas and professions make use of digital resources. The school can not be brushed off this reality, aim to create full subjects and integrated in society today. Educational software can be used very early in the education of children, but they must be carefully and monitoring. This article aims to present the results of the use of educational software in English to the awareness of context with children of pre-school education in kindergarten, nursery center Redemptorist Fathers - The smallest fox in White Castle, a 21 group children under 5 years. Early awareness of foreign language such as English can be started with digital multimedia capabilities and various software available on the market. However, the small study described the case reveals some resistance from parents and educators, in the preparation of these to choose and monitor the use of ICT by children, in addition to also highlight the self-interest of the children involved and their learning a few words in English language in different contexts of daily worked. The study opens perspectives on close monitoring needs of such uses and training of educators in the field of use of resources multilingual awareness in pre-school education.
