An integrated perspective to approach technology in mathematics education
This paper concerns a research work developed in an European project. The aim of this work was to produce a document integrating the different theoretical frameworks employed by the project teams. The theoretical constructs of didactical functionalities, and experimental educational cycle, associated to an ICT tool, allowed us to analyse the roles played by technology in the considered set of theoretical frameworks. With this respect, we present examples concerning the theory of didactic situati
Digestive System
The digestive system is amazing: it takes the foods we eat and breaks them into smaller components that our body can use for energy, cell repair and growth. This lesson introduces students to the main parts of the digestive system and how they interact. In addition, students learn about some of the challenges astronauts face when trying to eat in outer space. Engineering helps figure out how to deal with such challenges.
An Advisory QoS Service for GRID Based Learning Environments
This paper argues that the assumption of end-to-end QoS provision for use in Grid based applications is unsafe. We present an architecture which provides an adaptive QoS service for GRID applications which are prepared to adapt rather than assume the best and then suffer the worst.
This is particularly relevant to Internet based GRIDs. An example application from the field of collaborative learning environments is given, featuring adaptive QoS for Real Time Protocol (RTP) based audio and visual
How Clean is that Water?
This lesson plan helps students understand the factors that affect water quality and the conditions that allow for different animals and plants to survive. Students will look at the effects of water quality on various water-related activities and describe water as an environmental, economic and social resource. The students will also learn how engineers use water quality information to make decisions about stream modifications.
A River Ran Through It
Students learn how water is used to generate electricity. They investigate water’s potential-to-kinetic energy transformation in hands-on activities about falling water and waterwheels. During the activities, they take measurements, calculate averages and graph results. Students also learn the history of the waterwheel and how engineers use water turbines in hydroelectric power plants today. They discover the advantages and disadvantages of hydroelectric power. In a literacy activity, students
Electrons on the Move
Students learn about current electricity and necessary conditions for the existence of an electric current. Students construct a simple electric circuit and a galvanic cell to help them understand voltage, current and resistance.
Embedding knowledge in the design of an orthopaedic surgery learning
environment
This paper deals with an ongoing work involving surgeons, didacticians and computer
scientists. The objective is to design a computer based environment for learning screw
placement in orthopaedic surgery on the basis of a computer assisted surgical (CAS) tool. We
describe our methodology to create a didactical plug-in component for the CAS system. The
created system will consider the user's knowledge employed for the task to provide linked and
relevant feedback.
Group Reflection Tools for Virtual Expert Community - REFLEX Project
The aim of this project is to improve work quality, creativity and performance in various professional communities of knowledge-intensive companies by integrating teamwork and learning in collectively designed information spaces. This project will provide a pedagogical model for building and sharing expert knowledge within physically distributed teams that have a need to collaborate and co-ordinate information. The project will utilize latest information and communication technologies in develop
Falling Water
Students drop water from different heights to demonstrate the conversion of water’s potential energy to kinetic energy. They see how varying the height from which water is dropped affects the splash size. They follow good experiment protocol, take measurements, calculate averages and graph results. In seeing how falling water can be used to do work, they also learn how this energy transformation figures into the engineering design and construction of hydroelectric power plants, dams and reserv
What have the Romans ever done for us? - Global Europe from a Dutch perspective
Frans Timmermans will address issues of the changing political economy and the role the European Union can play in facing the challenges of today. The soft power of the EU is no longer limited to stabilisation and transformation of societies alone. Europe sets the standard in many fields. Yet, as Frans Timmermans will argue, pursuing the vision of Europe as a model power imposes a growing need for the Union's member states to start thinking and behaving in political terms. Less as a collection o
The Two Faces of Asia: bridging the gap between high growth economies and the poor
Despite impressive growth over the past few decades, the Asia Pacific region is still home to two-thirds of the world's poor. In many Asian countries, the gap between rich and poor is widening and policymakers are faced with extraordinary challenges in closing this gap and spreading the benefits of growth to the most vulnerable in their societies. Rising fuel and food prices have exacerbated these inequities and placed millions more on the edge of poverty. The Managing Director General of the As
Human Rights in United Nations Action: Norms, Institutions and Leadership
Navanethem Pillay is UN High Commissioner for Human Rights, she took up office on 1 September 2008. Ms. Pillay, a South African national, was the first woman to start a law practice in her home province of Natal in 1967. Over the next few years, she acted as a defense attorney for anti-apartheid activists, exposing torture, and helping establish key rights for prisoners on Robben Island.
LSE Director's Dialogue with Stephen Green
As the world's financial order is in a state of flux, how do we align our desire to improve material human wealth, and capitalism, with our spiritual and psychological needs? Do businesses and banks in particular have a duty to society that goes beyond the creation of profit? Does open market capitalism remain our best hope for creating wealth that benefits all of society? Green and Davies discuss history, politics, religion and economics. This event marks the launch of Stephen Green's book Goo
La peinture animée depuis Emile Reynaud
En 1880 avec son Praxinoscope à projection, Emile Reynaud parvient à coupler la synthèse graphique du mouvement avec la lanterne magique, créant une nouvelle technique de peinture animée lumineuse, distincte des formes antérieures de projection et qui précède le cinéma photographique. Inventeur et artiste accompli, il crée ensuite le jeu expressif des personnages peints et animés dans ses Pantomimes Lumineuses, puis la Photo Peinture animée. De toutes ces inventions on peut retro

The mechanisms of boiling (video)
Boiling is an effective way to remove heat. It is used as cooling medium in many industrial power such as power plants. The mechanisms governing the different regimes occurring during the boiling of a liquid usually are complex and often intertwined. It is important to know them and identify them in the laboratory. In particular, the detailed understanding of the boiling crisis, well known and feared for the damage that can result in practice is of primary importance. (For the boiling of a s

2.3.2 Salinity, desiccation and biotic interactions on seashores Tidal movements ensure that sea-shore habitats are, if not covered by seawater for part of each day, at least subject to spray-borne salt and wind. So, even well above the level of high tides, sea-shore organisms need to be more tolerant of salt than most terrestrial organisms. However, salinity (the concentration of salts dissolved in water) is not the only factor affecting sea-shore species. Seaweeds and shelled animals like limpets and barnacles are adapted to living in a highly saline mar
Studying mammals: Plant predators
From the mouse-deer to the elephant, plant eaters come in all shapes and sizes. But how do they manage to flourish on a salad diet? In this unit we will examine the special features that allow them to extract their nutrients from leaves, and see how some plants protect themselves from these predators. This is the fourth unit in the ‘Studying mammals’ series.
