Dans cette étude, nous nous sommes intéressé à l’utilisation des TIC, plus précisément du Tableau Numérique Interactif (TNI), en géométrie, par des groupes d’élèves de deux classes du primaire en pédagogie Freinet. S’inspirant d’une revue de littérature concernant la pédagogie dialogique, qui se rapproche de la pédagogie Freinet, trois unités d’observation, qui se rapportent aux trois types de discussion (cumulatif, disputationnel et exploratoire) au sein des groupes, ont été analysées. Le but de l’étude est de comprendre en quoi les discussions des groupes d’élèves autour du TNI, dans un contexte dit dialogique, peuvent être exploratoires (un type de discussion qui favoriserait les apprentissages). Pour cela, une activité d’apprentissage, appelée situation-problème, impliquant six groupes d’élèves autour du TNI, a été créée en collaboration avec les enseignants en géométrie. Nos résultats indiquent, entres autres, que les aspects pédagogiques de la technologie en question, ici le TNI, sont à différencier des aspects pédagogiques du logiciel utilisé, ici Tinkercad en mathématiques. Ce mémoire remet en relief toute la complexité de prendre en compte un unique facteur (l’analyse des discussions) pour discuter des apprentissages des élèves autour du TNI.

Urgency to embed awareness of sustainability principles and practice across society, and need for digital literacy and advocacy for sustainability are reshaping ESD. These, together with developments in learning and teaching, demand new tools to support implementation of project-based learning and more interactive approaches. This investigation explores the evolution of susthingsout.com, an online magazine for students, academics and expert practitioners, developed by the University of Worcester. This comprises two parts; the first, a private site specifically for students involved in sustainability learning on-campus; the second, an open-access site developed to deliver sustainability information and good practice across campus, community and not-for-profit and commercial organisations. This paper involves only the private site i.e. the equivalent of an in-house VLE specifically designed to support the teaching of sustainability to multi-disciplinary first and second year undergraduate students. It reports on the progress of the VLE, following three years of use and initial improvements, in terms of the student support and engagement, as well as considering the practical issues affecting these. The results fall into four categories of pedagogical, operational, cultural and external factors, which are synthesised to capture and share emerging knowledge of good practice offering insights to other developers of online sustainability materials.

This interactive symposium will focus on the use of different technologies in developing innovative practice in teacher education at one university in England. Technology Enhanced Learning (TEL) is a field of educational policy and practice that has the power to ignite diametrically opposing views and reactions amongst teachers and teacher educators, ranging across a spectrum from immense enthusiasm to untold terror. In a field where the skills and experience of individuals vary from those of digital natives (Prensky 2001) to lags and lurkers in digital spaces, the challenges of harnessing the potential of TEL are complex. The challenges include developing the IT skills of trainees and educators and the creative application of these skills to pedagogy in all areas of the curriculum. The symposium draws on examples from primary, secondary and post-compulsory teacher education to discuss issues and approaches to developing research capacity and innovative practice using different etools, many of which are freely available. The first paper offers theoretical and policy perspectives on finding spaces in busy professional lives to engage in research and develop research-informed practice. It draws on notions of teachers as researchers, practitioner research and evidenc-ebased practice to argue that engagement in research is integral to teacher education and an empowering source of creative professional learning for teachers and teacher educators. Whilst acknowledging the challenges of this stance, examples from our own research practice illustrate how e-tools can assist us in building the capacity and confidence of staff and students in researching and enhancing teaching, learning and assessment practice. The second paper discusses IT skills development through the TEL pathway for trainee teachers in secondary education across different curriculum subjects. The lead tutor for the TEL pathway will use examples of activities developed with trainee teachers and university subject tutors to enhance their skills in using e-tools, such as QR codes, Kahoot, Padlet, Pinterest and cloud based learning. The paper will also focus on how these skills and tools can be used for action Discussant - the wider use of technologies in a university centre for teacher education; course management, recruitment and mentor training. research, evaluation and feedback and for marking and administrative tasks. The discussion will finish with thoughts on widening trainee teachers’ horizons into the future direction of educational technology. The third paper considers institutional policies and strategies for promoting and embedding TEL, including an initiative called ‘The Learning Conversation’, which aims ‘to share, highlight, celebrate, discuss, problematise, find things out...’ about TEL through an online space. The lead for ‘The Learning Conversation’ will offer reflections on this and other initiatives across the institution involving trainee teachers, university subject tutors, librarians and staff in student support services who are using TEL to engage, enthuse and support students on campus and during placements in schools. The fourth paper reflects on the use of TEL to engage with trainee teachers in post-compulsory education. This sector of education and training is more fragmented than primary and secondary schools sectors and so the challenges of building a community of practice that can support the development of innovative practice are greater.

Inom ramen för gymnasieskolans yrkesprogram förläggs en del av elevens utbildning på en arbetsplats, APL. APL är betydelsefull för yrkesprogrammen eftersom hela utbildningen syftar till att knyta an till kommande yrkesroll och lära sig yrket tillsammans med redan yrkesverksamma. Bakgrunden till föreliggande studie är ett intresse för vilket lärande som pågår ute på arbetsplatserna och vad handledarna uppfattar som viktigt lärande för kommande yrkesutövning. Syftet med studien är att beskriva vad handledarna uppfattar att eleverna ska lära sig samt bedömning av elevernas kunskapsutveckling under APL. Studien är en kvalitativ studie och har omfattat intervjuer med 12 handledare med anknytning till gymnasieskolans bygg- och anläggningsprogram. Studien tar sin utgångspunkt i livsvärldsfenomenologin med fenomenografi som metodisk ansats för att beskriva handledarnas uppfattningar av APL. Resultatet av studien visar att handledarna beskriver att de inte har fått tillräckligt med kunskap och information från skolan om vad eleverna ska lära sig på APL. Detta kan innebära svårigheter att hitta passande arbetsuppgifter. Det råder vidare en brist på kunskap om vad och hur de bedömer elevernas lärande vilket leder till att eleverna bedöms på oklara grunder. Sammanfattningsvis visar således studien att det finns delar av APL som behöver förbättras och utvecklas för att nå en högre kvalitet i det arbetsplatsförlagda lärandet. Samarbetet skola och fö-retag måste förbättras, och fler handledare måste få en pedagogisk handledarutbildning.

Se analiza la emergencia del concepto de “articulador” dentro de la estrategia pedagógica del aprendizaje basado en problemas (ABP). A través de esta los miembros de un grupo de trabajo recuperan información que les permite examinar un problema desde distintos puntos de vista. Mediante la experiencia de trabajo entre profesores, entre estudiantes y entre ambos, el articulador funciona como eje de integración de conocimientos que responden a aspectos particulares del problema, que son definidos y reflexionados por el grupo. Abstract The article of analyzes the emergence of the concept ≪articulator≫ in the pedagogical strategy of problem-based learning (ABP). Through this strategy the members of a working group recover information that allows them to examine a problem from different points of view. Through the experience of work between professors, between students and between them, the articulator works like axis of integration of knowledge that respond to particular aspects of the problem, which are defined and reflected by the group.

El estudio tuvo como propósito determinar la efectividad relativa del ABP, comparado con el método tradicional para desarrollar habilidades de resolución de problemas en el aprendizaje de las aplicaciones de la solución de triángulos en el grado 10º de la Institución Educativa El Progreso, de El Carmen de Viboral, Antioquia. La enseñanza-aprendizaje de las matemáticas sustentadas con la estrategia didáctica Aprendizaje Basado en Problemas permite a los estudiantes y docentes aproximarse al conocimiento de una manera similar a como lo hacen los científicos; el primer paso es una situación de duda, perplejidad del estudiante provocada por la Situación Problema planteada por el docente, el segundo un momento de “sugerencias” en las que la mente salta hacia adelante en busca de una posible solución (Dewey, 1933, p. 102). El tercer paso “intelectualización” de la dificultad que se ha percibido para convertirlo en un problema que debe solucionarse (Dewey, 1933, p. 103). La cuarta es “la idea conductora o hipótesis”, las cuales se basan en la formulación de explicaciones sugeridas o soluciones posibles (Dewey, 1933, p. 104). El quinto paso sería el “razonamiento”, consiste en la elaboración racional de una idea que se va desarrollando de acuerdo a las habilidades de cada persona (Dewey, 1933, p. 105). El paso final es la “comprobación de hipótesis” en situaciones reales. Este proceso se evidenció a través de cuatro Situaciones-Problema enfocadas desde un contexto auténtico “la remodelación del parque principal de El Carmen de Viboral” con el objetivo de motivar a los estudiantes para el aprendizaje de algunos conceptos matemáticos y el desarrollo de habilidades de resolución de problemas. La metodología de la investigación fue un diseño cuasi-experimental con grupo experimental compuesto por 38 estudiantes del grado 10º2 y grupo control con 37 estudiantes del grado 10º1. Se empleó como técnica de recolección de la información una prueba pre-test antes del tratamiento y una prueba post-test que se aplicó después del tratamiento a ambos grupos; se aplicó también una escala de satisfacción de los estudiantes con la metodología tradicional en ambos grupos y una escala de satisfacción con la estrategia didáctica ABP sólo al grupo experimental; la observación directa, y el portafolio que evidenciaba todas las construcciones de los estudiantes. La aplicación de la estrategia didáctica experimental se aplicó durante 4 meses, con una intensidad horaria de cuatro horas semanales, tiempo durante el cual se implementaron las cuatro Situaciones-Problema. Se concluyó entre otros aspectos que el 86,5% de los estudiantes encuentran las clases de matemáticas como interesantes, contextualizadas, aplicables y significativas, mientras que antes del tratamiento sólo el 44,4% se encontraba satisfecho con las clases de matemáticas, con una diferencia en cambio de actitud de 42,1% frente a las clases de matemáticas con la metodología tradicional. En el análisis comparativo de adquisición de competencias específicas se demuestra que el grupo experimental demostró ser matemáticamente más competente con respecto al grupo control en todas las competencias evaluadas: capacidad de modelación, inductiva, comunicativa y habilidad procedimental. Además, el proyecto de investigación tuvo un valor agregado: 10 estudiantes tuvieron la oportunidad de conocer más sobre su cultura ceramista mediante el diseño y construcción de mosaicos que los ofreció la casa de la cultura en forma gratuita.

Decision-making is often dependent on uncertain data, e.g. data associated with confidence scores or probabilities. We present a comparison of different informa- tion presentations for uncertain data and, for the first time, measure their effects on human decision-making. We show that the use of Natural Language Genera- tion (NLG) improves decision-making un- der uncertainty, compared to state-of-the- art graphical-based representation meth- ods. In a task-based study with 442 adults, we found that presentations using NLG lead to 24% better decision-making on av- erage than the graphical presentations, and to 44% better decision-making when NLG is combined with graphics. We also show that women achieve significantly better re- sults when presented with NLG output (an 87% increase on average compared to graphical presentations).

W zależności od ujęcia projekt jest metodą lub strategią nauczania (Nowacki i wsp, 1999). W niektórych źródłach zaliczany do grupy metod nauczania przez dociekanie (ang. inquiry based learning) (Bransford i in., 2000). Metody nauczania oparte na dociekaniu zyskują coraz bardziej na popularności, także w dydaktyce akademickiej. W niniejszej pracy przedstawiono analizę jakościową 25 projektów zajęć dydaktycznych opracowanych przez doktorantów Wydziału Biologii UAM, w których projekt badawczy był składnikiem projektu edukacyjnego, a całość była propozycją zajęć dla studentów tegoż wydziału.

Processors with large numbers of cores are becoming commonplace. In order to utilise the available resources in such systems, the programming paradigm has to move towards increased parallelism. However, increased parallelism does not necessarily lead to better performance. Parallel programming models have to provide not only flexible ways of defining parallel tasks, but also efficient methods to manage the created tasks. Moreover, in a general-purpose system, applications residing in the system compete for the shared resources. Thread and task scheduling in such a multiprogrammed multithreaded environment is a significant challenge. In this thesis, we introduce a new task-based parallel reduction model, called the Glasgow Parallel Reduction Machine (GPRM). Our main objective is to provide high performance while maintaining ease of programming. GPRM supports native parallelism; it provides a modular way of expressing parallel tasks and the communication patterns between them. Compiling a GPRM program results in an Intermediate Representation (IR) containing useful information about tasks, their dependencies, as well as the initial mapping information. This compile-time information helps reduce the overhead of runtime task scheduling and is key to high performance. Generally speaking, the granularity and the number of tasks are major factors in achieving high performance. These factors are even more important in the case of GPRM, as it is highly dependent on tasks, rather than threads. We use three basic benchmarks to provide a detailed comparison of GPRM with Intel OpenMP, Cilk Plus, and Threading Building Blocks (TBB) on the Intel Xeon Phi, and with GNU OpenMP on the Tilera TILEPro64. GPRM shows superior performance in almost all cases, only by controlling the number of tasks. GPRM also provides a low-overhead mechanism, called “Global Sharing”, which improves performance in multiprogramming situations. We use OpenMP, as the most popular model for shared-memory parallel programming as the main GPRM competitor for solving three well-known problems on both platforms: LU factorisation of Sparse Matrices, Image Convolution, and Linked List Processing. We focus on proposing solutions that best fit into the GPRM’s model of execution. GPRM outperforms OpenMP in all cases on the TILEPro64. On the Xeon Phi, our solution for the LU Factorisation results in notable performance improvement for sparse matrices with large numbers of small blocks. We investigate the overhead of GPRM’s task creation and distribution for very short computations using the Image Convolution benchmark. We show that this overhead can be mitigated by combining smaller tasks into larger ones. As a result, GPRM can outperform OpenMP for convolving large 2D matrices on the Xeon Phi. Finally, we demonstrate that our parallel worksharing construct provides an efficient solution for Linked List processing and performs better than OpenMP implementations on the Xeon Phi. The results are very promising, as they verify that our parallel programming framework for manycore processors is flexible and scalable, and can provide high performance without sacrificing productivity.

Research on the impact of the Project Approach on young children with disabilities or children who are at-risk is limited. Mixed methods were used to study the impact of the Project Approach on the social interactions, challenging behaviors, and language development of eight focal children in two inclusive classrooms. Child participants were two children with IEPs and two children identified as at-risk from each class. Adult participants were six professionals who received high quality supports to implement the Project Approach. Adults were interviewed prior to the beginning of the study and again mid-, and post-implementation. Choice time observations were videotaped twice per week over 14 weeks to assess the impact of the Project Approach on play levels and MLUm. Results revealed that social interactions, challenging behaviors, vocabulary, MLUm, were positively impacted following implementation of the Project Approach. Limitations of the study and suggestions for research and practice are discussed.

Numa época em que nos regemos, cada vez mais, pela Ciência e Tecnologia é fundamental que os cidadãos estejam devidamente informados, exercendo uma cidadania plena, tomando decisões fundamentadas e intervindo na sociedade. Para viabilizar estes intentos, é importante que a educação científica se inicie nas escolas o mais cedo possível, para a edificação de futuros cidadãos cientificamente literatos. Apesar das dificuldades manifestadas pelos professores na implementação do ensino das Ciências nas escolas do 1.º Ciclo do Ensino Básico (1.º CEB), são várias as potencialidades que têm vindo a ser atribuídas a este campo curricular. Com este estudo pretendeu-se descrever e interpretar as conceções de ensino e aprendizagem de professores do 1.º CEB, no contexto do Programa de Formação em Ensino Experimental das Ciências (PFEEC), bem como averiguar como implementam as atividades práticas de índole experimental e investigativo em sala de aula, e quais as dificuldades sentidas durante a sua realização. Para atingir estas finalidades, utilizou-se uma abordagem metodológica de orientação interpretativa, de base naturalista, recorrendo-se ao método de estudo de casos múltiplos, fazendo-se uso de distintos instrumentos de recolha de dados: observação naturalista, entrevistas, notas de campo e documentos escritos. Participaram neste estudo três professoras do 1.º CEB, pertencentes a duas escolas do concelho de Faro. Os resultados evidenciaram que a maioria das conceções das professoras relativamente às categorias edificadas foram modificadas após a frequência do PFEEC. Contudo, outras aparentam estar fortemente enraizadas. Estas mudanças que ocorreram parecem estar relacionadas com a modificação das ações, atitudes e sentimentos das professoras que se coadunaram com a metodologia de trabalho defendida pelo PFEEC, culminando na modificação das suas práticas letivas. Durante a planificação e implementação das atividades as professoras manifestaram algumas dificuldades e constrangimentos. Todavia, no decorrer do PFEEC, estes obstáculos foram sendo minimizados; IMPACT OF A TRAINING PROGRAMME ON THE CONCEPTIONS AND PRACTICES OF PRIMARY SCHOOL TEACHERS ABSTRACT: In an era in which we are governed, more and more, by Science and Technology, it is fundamental that citizens are properly informed; exercising full citizenship; making fundamental decisions and intervening in society. To enable these intentions, it is important that scientific education takes place in schools as soon as possible, so as to edify future scientifically literate citizens. Despite the teachers' difficulties in implementing Science teaching in Primary Schools, there are many potentialities that have come to be attributed to this curricular field. This study is intended to describe and interpret science learning and teaching conceptions of the Primary School teachers, in the context of the Training Programme in Experimental Science Teaching (PFEEC), as well as determine how they implement the experimental science and inquiry based learning activities in the classroom, and take into account what experienced difficulties occur during their execution. To reach these goals, a methodological approach of interpretive orientation, on a naturalistic basis, using a method of multiple case study, by means of distinct data collection tools was used: naturalistic observation, interviews, field research notes and written documents. Three Primary School teachers of the municipality of Faro took part in this study. The results showed that the majority of the teachers' conceptions in relation to the edified categories were modified after the attendance of the PFEEC. However, others seem to be deeply rooted. These changes that occurred seem to be related to the modification of actions, attitudes and feelings of the teachers who complied with the work methodology defended by the PFEEC, culminating in the modification of their session practices. During the planning and implementation of the activities, the teachers showed some difficulties and constraints. Nevertheless, during the PFEEC, these obstacles were minimized.
