This study used a mixed methods approach to develop a broad and deep understanding of students’ perceptions towards creativity in engineering education. Studies have shown that students’ attitudes can have an impact on their motivation to engage in creative behavior. Using an ex-post facto independent factorial design, attitudes of value towards creativity, time for creativity, and creativity stereotypes were measured and compared across gender, year of study, engineering discipline, preference for open-ended problem solving, and confidence in creative abilities. Participants were undergraduate engineering students at Queen’s University from all years of study. A qualitative phenomenological methodology was adopted to study students’ understandings and experiences with engineering creativity. Eleven students participated in oneon- one interviews that provided depth and insight into how students experience and define engineering creativity, and the survey included open-ended items developed using the 10 Maxims of Creativity in Education as a guiding framework. The findings from the survey suggested that students had high value for creativity, however students in fourth year or higher had less value than those in other years. Those with preference for open-ended problem solving and high confidence valued creative more than their counterparts. Students who preferred open-ended problem solving and students with high confidence reported that time was less of a hindrance to their creativity. Males identified more with creativity stereotypes than females, however overall they were both low. Open-ended survey and interview results indicated that students felt they experienced creativity in engineering design activities. Engineering creativity definitions had two elements: creative action and creative characteristic. Creative actions were associated with designing, and creative characteristics were predominantly associated with novelty. Other barriers that emerged from the qualitative analysis were lack of opportunity, lack of assessment, and discomfort with creativity. It was concluded that a universal definition is required to establish clear and aligned understandings of engineering creativity. Instructors may want to consider demonstrating value by assessing creativity and establishing clear criteria in design projects. It is recommended that students be given more opportunities for practice through design activities and that they be introduced to design and creative thinking concepts early in their engineering education.

Online gambling is a popular activity among adolescents. However, there has been a notable increase in the number of young people who suffer or are on the verge of pathological gambling. We review the impact of online gambling on young people and discuss the desiderability of the concept of “gambling responsibly” in order to alert of their risks and effectively prevent access to minors. The main factors associated with pathological gambling are the age of start, the family environment, the infl uence of advertising, the consumption of stimulants, and the attitudes of the peer group. Both the government and the gaming industry itself should consider these factors and develop comprehensive plans that ensure a safe and controlled model game. In this context, advertising must take into account criteria of consumer protection knowing that even if they are not allowed, children can easily have access to online gambling. All agents involved, including public and social agents, must provide mechanisms for prevention and awareness of a problem that arouses little social consciousness and excessive carelessness.

The hypothesis that the same educational objective, raised as cooperative or collaborative learning in university teaching does not affect students’ perceptions of the learning model, leads this study. It analyses the reflections of two students groups of engineering that shared the same educational goals implemented through two different methodological active learning strategies: Simulation as cooperative learning strategy and Problem-based Learning as a collaborative one. The different number of participants per group (eighty-five and sixty-five, respectively) as well as the use of two active learning strategies, either collaborative or cooperative, did not show differences in the results from a qualitative perspective.

Este trabajo presenta la reelaboración de un modelo de producción de textos escritos, publicado por el Grupo Didactext en 2003. Se sitúa en un marco sociocognitivo, lingüístico y didáctico, y está concebido desde la interacción de tres dimensiones simbolizadas por círculos concéntricos recurrentes. El primer círculo corresponde al ámbito cultural: las diversas esferas de la praxis humana en las que está inmersa toda actividad de composición escrita. El segundo se refiere a los contextos de producción, de los que forman parte el contexto social, el situacional, el físico, la audiencia y el medio de composición. El tercer círculo corresponde al individuo, en el que se tiene en cuenta el papel de la memoria en la producción de un texto desde el enfoque sociocultural, la motivación, las emociones y las estrategias cognitivas y metacognitivas, dentro de las cuales se conciben seis unidades funcionales que actúan en concurrencia: acceso al conocimiento, planificación, redacción, revisión y reescritura, edición, y presentación oral. La orientación didáctica se interesa por la enseñanza y el aprendizaje de la escritura académica en las aulas, así como por la investigación de la escritura en contextos de educación.

Abstract. The performance objectives used for the formative assessment of com- plex skills are generally set through text-based analytic rubrics[1]. Moreover, video modeling examples are a widely applied method of observational learning, providing students with context-rich modeling examples of complex skills that act as an analogy for problem solving [1]. The purpose of this theoretical paper is to synthesize the components of video modeling and rubrics to support the formative assessment of complex skills. Based on theory, we argue that application of the developed Video Enhanced Rubrics (VER) fosters learners’ development of mental models, quality of provided feedback by various actors and finally, the learners mastery of complex skills.

Depuis les années 1980, le développement de l’autodétermination des personnes présentant une déficience intellectuelle (DI) est devenu une priorité dans les interventions qui leur sont offertes. Les agents de socialisation (p.ex., éducateurs, travailleurs sociaux, enseignants, parents, etc.) ont un rôle crucial dans sa promotion de par le soutien qu’ils leur offrent et les apprentissages qu’ils tentent de favoriser chez elles. La façon de communiquer et le type de relation que les agents de socialisation établissent avec la personne présentant une DI ont une influence certaine dans son développement. Pourtant, peu d’études ont jusqu’à ce jour évalué quelles sont les manières optimales de communiquer et d’interagir des agents socialisation pouvant faciliter l’autodétermination des personnes présentant une DI. Ancrée dans la théorie de l’autodétermination (TAD), cette thèse s’intéresse à évaluer, les effets d’un type de soutien spécifique, le soutien à l’autonomie (ou à l’autodétermination; SA, une manière de communiquer et d’être en relation qui satisfait le besoin d’autodétermination), sur la satisfaction du besoin d’autodétermination et la présence de bénéfices comportementaux, motivationnels et affectifs chez les personnes présentant une déficience intellectuelle légère (DIL) dans un contexte d’apprentissage. Deux articles seront présentés dans cette thèse. Le concept d’autodétermination comprend une large littérature et revêt de multiples définitions. Le premier article, de nature théorique, permettra de mieux le comprendre et de l’éclaircir à la lumière de la théorie fonctionnelle de l’autodétermination (TfAD) et de la théorie de l’autodétermination (TAD). Les études portant sur les interventions de promotion de l’autodétermination de la TAD et de la TfAD seront présentées. Dans un deuxième temps, la TAD et la TfAD seront comparées et contrastées l’une avec l’autre ce qui permettra de démontrer leurs différences, leurs similarités et leurs complémentarités tant au niveau théorique que de l’intervention. Enfin, il est proposé que le SA étudié par la TAD puisse constituer une intervention prometteuse, en plus des interventions proposées par la TfAD, afin de favoriser le développement de l’autodétermination et engendrer des bénéfices comportementaux, motivationnels et affectifs chez cette population. La deuxième étude visera à évaluer cette proposition. Par le biais d’une étude expérimentale, il sera évalué si le SA peut satisfaire le besoin d’autonomie/autodétermination des personnes présentant une DIL et peut faciliter l’intériorisation de la valeur d’une tâche, l’engagement et la diminution de l’anxiété lorsqu’ils réalisent une tâche de résolution de problème, une activité d’apprentissage qui est à la fois importante et fastidieuse. Ainsi, l’étude permettra de comparer les effets d’une tâche réalisée avec ou sans SA (condition expérimentale et témoin respectivement). Les participants (N = 51) présentaient tous une DIL et ont été recrutés dans un centre de réadaptation de la région de Montréal, au Québec (Canada). Les résultats démontrent que comparativement à la condition témoin, le SA amène chez les participants une satisfaction plus élevée du besoin d’autodétermination, un plus grand niveau d’engagement, une plus grande diminution de leur anxiété lors de l’activité et facilite l’intériorisation de la valeur de la tâche. La signification et l’interprétation de ces résultats, de même que leurs implications potentielles pour la recherche et les interventions offertes à ces personnes sont finalement discutées.

Purpose The aim of the study is to explore the role of confluent learning in supporting the development of change management knowledge, skills and attitudes and to inform the creation of a conceptual model based upon a priori and a posteriori knowledge gained from literature and the research. Design/methodology/approach The research adopts qualitative approach based on reflective inquiry methodology. There are two primary data sources, interviews with learners and the researchers’ reflective journals on learners’ opinions. Findings The confluent learning approach helped to stimulate affective states (e.g. interest and appreciation) to further reinforce cognitive gains (e.g. retention of knowledge) as a number of higher order thinking skills were further developed. The instructional design premised upon confluent learning enabled learners to further appreciate the complexities of change management. Research implications/ limitations The confluent learning approach offers another explanation to how learning takes place, contingent upon the use of a problem solving framework, instructional design and active learning in developing inter- and trans-disciplinary competencies. Practical implications This study not only explains how effective learning takes place but is also instructive to learning and teaching, and human resource development (HRD) professionals in curriculum design and the potential benefits of confluent learning. Social implications The adoption of a confluent learning approach helps to re-naturalise learning that appeals to learners affect. Originality/value This research is one of the few studies that provide an in-depth exploration of the use of confluent learning and how this approach co-develops cognitive abilities and affective capacity in the creation of a conceptual model.

As situações indutoras de stress são uma constante imutável no dia-a-dia do ser humano e quando esta perturbação não é gerida de forma adequada, acarreta graves prejuízos na saúde dos indivíduos refletindo-se em diversas áreas das suas vidas nomeadamente no trabalho. O presente estudo tem como finalidade identificar a relação entre o stress e as estratégias de coping e perceber se os indivíduos com vulnerabilidade ao stress diferem dos indivíduos sem stress no que concerne às estratégias de coping utilizadas. A vulnerabilidade ao stress foi medida pela escala 23QVS, enquanto as estratégias de coping foram avaliadas pelo Inventário de Resolução de Problemas (IRP), tendo sido, ainda, utilizado um questionário sociodemográfico. A amostra foi composta por 62 trabalhadores de uma empresa de venda a retalho com idades compreendidas entre os 20 e os 44 anos (M=32,02 DP=5,770). Os resultados obtidos revelaram que a vulnerabilidade ao stress se correlaciona de forma negativa e altamente significativa com as estratégias de coping e que indivíduos com e sem vulnerabilidade ao stress não diferem quanto ao uso destas estratégias. / The stress-induction situations are a constant unchanging in human being life, and if this disturbance is not managed adequately can be harmful to the health of individuals and reflected in many areas of their lives including their work. The present study aims to analyze the relationship between stress and coping strategies, and understand if individuals with stress vulnerability differs from individuals without stress in respect to the use of coping strategies. Stress vulnerability was measured by the 23QVS scale and coping strategies by the Inventário de Resolução de Problemas – IRP (Inventory of Problem Solving), and we also used a sociodemographic questionnaire. The sample consisted of 62 workers of a retailing company with ages between 20 and 40 years old (M = 32,02; DP = 5,770). Our research studies reveal that stress vulnerability correlates negatively and highly with coping strategies, and individuals with and without stress vulnerability not differ in the use of these strategies.

Our society is currently facing complex challenges, such us climate change, loss of biodiversity, ageing population, unemployment, to name but a few. This has created growing expectations on designers and engineers to explore, experiment and implement innovative solutions to such issues. At this critical time, if we want design to be part of the solution, we need to wonder whether we are asking designers suitable and sustainable questions. Both in post-graduate design education and in business, the brief still overwhelmingly requires designers to follow a linear problem-solving approach that focuses on product rather than strategies, services and systems. Traditional design briefs result no longer appropriate to face the challenges of our unsustainable world, as they relate to market, growth economy and human needs rather than society, business models and the needs of nature. Instead, we need to be asking questions about, for example, how we create sustainable business opportunities, how we overcome the barriers for change, or how we facilitate the process of innovation through design methodology. If the role of design is to create new visions and outline strategic directions towards a sustainable future world - for policy makers, businesses, communities and individual citizens – we need those stakeholders to create briefs for designers that allow them to do that. This paper will explain how the reframing of questions has been embedded into SustainRCA’s teaching practice in post-graduate design, art and engineering, leading to the development of new tools and methods, as well as some innovative outcomes

Was man aus der deutschen PIAAC-Studie als prägnanteste Zusammenfassung herausziehen könnte, wäre: jeder sechste deutsche Erwachsene liest und rechnet auf dem Kompetenzniveau eines zehnjährigen Schülers und jeder zehnte deutsche Erwachsene kann mit einer "Maus" nicht umgehen. Oder, in Anlehnung an PIAAC: Im deutschen Bildungssystem besteht anscheinend nicht für alle Menschen die Möglichkeit, ein über elementare Grundkompetenzen hinaus gehendes Niveau zu erreichen. Diese Ergebnisse sind zwar statistisch valide und belastbar, verkürzen jedoch ohne weitere Differenzierungen das Gesamtanliegen von PIAAC. (DIPF/Orig.)

Este estudo teve como principais objetivos compreender os efeitos de um projeto de educação global nos conhecimentos, capacidades e atitudes de um grupo de alunos portugueses do 11.º ano, bem como compreender as potencialidades da aula de língua inglesa no âmbito de uma educação promotora da participação ativa numa sociedade globalizada. Tratando-se de um estudo de tipo investigação-ação, ancorado no paradigma socio-crítico, foram recolhidos dados através de questionários, aplicados aos alunos antes e após o projeto de intervenção, de gravações vídeo de quatro sessões de educação global e de uma entrevista realizada à professora cooperante. Recorreu-se ainda à recolha documental de trabalhos dos alunos, bem como do Programa de Inglês (continuação) dos 10.º, 11.º e 12.º anos. A análise dos dados recolhidos, efetuada segundo diferentes métodos e instrumentos, permitiu concluir que o projeto de educação global teve efeitos mais significativos no desenvolvimento dos conhecimentos dos alunos, sobretudo relacionados com problemas globais específicos, tendo estes compreendido que o que acontece em outros locais tem relevância na vida de cada um. O estudo permitiu ainda verificar que as aulas de língua inglesa são o espaço ideal para se trabalhar a educação global, funcionando como uma porta aberta para outras línguas, culturas e mundivisões. Estes resultados sugerem que é possível e necessário promover o desenvolvimento da competência global na aula de línguas, mobilizando e incorporando saberes e recursos que valorizem capacidades de trabalho colaborativo, de comunicação e de resolução de problemas, bem como atitudes de respeito pelos Outros, imprescindíveis para o exercício da cidadania e para desafiar as injustiças e desigualdades que nos rodeiam.

O presente trabalho debruça-se sobre os constructos da liderança e do comportamento de auto-eficácia da liderança nas organizações. Reflecte-se sobre a importância dos sistemas de informação no clima organizacional, com efeitos sobre a eficácia na liderança. Trata-se de uma perspetiva pertinente na conjuntura organizacional atual, dado que incide sobre valores patrimoniais intangíveis que, quando dinamizados, dão suporte à performance organizacional. A nossa preocupação central é a auto-eficácia. Através dela pretende-se melhorar a eficiência organizacional, porque minimiza prejuízos e desperdícios. Também se relaciona a eficácia com o desempenho da liderança organizacional e com o capital ‘confiança’. Dessa forma, os novos caminhos passam por auscultar a percepção dos colaboradores sobre a importância da cultura organizacional face ao desempenho e à eficácia de longo prazo na organização. Com a presente reflexão, evidencia-se que a espiritualidade no local de trabalho é um factor de apoio ao desenvolvimento holístico dos colaboradores. Fica sublinhado que é fundamental que os líderes tenham noção e consciência de “si” e dos seus papéis, e como estes se reflectem no seu comportamento quotidiano na organização. O estudo assenta num trabalho de campo, elaborado numa organização intensiva em informação e que presta serviços de consultoria e informática. Os resultados apurados tentam dizer que, globalmente, no estudo longitudinal das hetero-percepções dos gestores directos e indirectos, o gap cultural diminuiu em todas as dimensões relativas às competências dos papéis, sendo vital destacar o quadrante designado por Apoio. As hetero-percepções dos gestores directos demonstram que o menor gap cultural mantem-se no quadrante de Objectivos Racionais e Competir no modelo de CVF, caracterizado por uma cultura de mercado, e relacionado com a fase da Combinação no modelo de SECI (processos que fomentam os relacionamentos e intercâmbios informais – conversão do conhecimento explícito para o explícito). Enquanto que o maior gap cultural reside no quadrante Apoio e Colaborar no modelo CVF, relacionado com a fase da Socialização no modelo de SECI (processos que fomentam os relacionamentos e intercâmbios informais – conhecimento tácito para tácito). Como o gap cultural diminuiu em todas as dimensões, pode realçar uma melhoria das percepções do desempenho organizacional. Contudo, um resultado inesperado está associado ao quadrante Apoio com a cultura de clã, uma vez que são os gestores indirectos na empresa em estudo que fomentam esta cultura, e não os gestores directos, conforme seria desejável. Um resultado favorável para o estudo da auto-eficácia da liderança demonstra que as médias são mais elevadas para atributos de Gestão e Resolução de Problemas. Os resultados que não corresponderam às expectativas iniciais estão associados às médias baixas relativamente aos atributos Sociais/de Comunicação, o que pode ser uma debilidade porque seria desejável que a equipa de gestão tivesse maior sensibilidade perante os capitais sociais, emocionais e espirituais, os quais estão relacionados com estes atributos.

The evolution and maturation of Cloud Computing created an opportunity for the emergence of new Cloud applications. High-performance Computing, a complex problem solving class, arises as a new business consumer by taking advantage of the Cloud premises and leaving the expensive datacenter management and difficult grid development. Standing on an advanced maturing phase, today’s Cloud discarded many of its drawbacks, becoming more and more efficient and widespread. Performance enhancements, prices drops due to massification and customizable services on demand triggered an emphasized attention from other markets. HPC, regardless of being a very well established field, traditionally has a narrow frontier concerning its deployment and runs on dedicated datacenters or large grid computing. The problem with common placement is mainly the initial cost and the inability to fully use resources which not all research labs can afford. The main objective of this work was to investigate new technical solutions to allow the deployment of HPC applications on the Cloud, with particular emphasis on the private on-premise resources – the lower end of the chain which reduces costs. The work includes many experiments and analysis to identify obstacles and technology limitations. The feasibility of the objective was tested with new modeling, architecture and several applications migration. The final application integrates a simplified incorporation of both public and private Cloud resources, as well as HPC applications scheduling, deployment and management. It uses a well-defined user role strategy, based on federated authentication and a seamless procedure to daily usage with balanced low cost and performance.
