This article will briefly present a few theses and reflections of mine on some perversions and disruptions under way in knowledge development and in science representation. Nevertheless, I will abstain from exposing thoroughly the obvious and triumphal side of the coin. Namely, I am not going to extol the amazing fortune of science and knowledge, which have become the fundamental resource for development, at economic level in first place. Indeed, having reached a certain age, I can allow myself ­ although to a certain degree of oversimplification ­ less enthusiasm and a few old-fashioned ideas.

In 2007, global investments in R&D have increased by 7% on the previous year and have reached an absolute historical peak, exceeding for the first time the threshold of 1,100 billion dollars (calculated in the hypothesis of a purchasing power parity between the currencies). The world invests in scientific research and technological development 2.1% of the wealth it produces. At the same time, there has been an increase in the exchange of high added-knowledge value goods and high tech represents now the most dynamic sector of the world economy.

Sometimes scientists live real dramas or undergo social and psychological conflicts which have a positive or negative influence on the development and recognition of their research, discoveries and inventions in society, including the way they are recorded in history. This being so, the question is: to what extent can science be communicated to the public at large by the use of scientists' biographies as a motivational strategy? The controversy arises from the fact that usual (classical) science has traditionally argued for the separation (or de-linking) of the research (the object) from the researcher (the subject).Thus, if the above-mentioned motivational strategy is used in scientific communication, it could break a dominant methodological trend and consequently lead to a questioning of the myth of axiological neutrality in science. The communication of science by means of scientists' biographies could be useful for reaching a specific public, more directed towards emotional aspects, thereby awakening its interest in science, even amid cultural differences and in environments where interest in science and its utility is lacking. It could also reveal human aspects of the everyday life of scientists, bringing them closer to the public at large, which would contribute to the dissemination of science and knowledge.

After serving the community for seven years, the Science Museum of Castilla-La Mancha (MCCM) has decided to renew itself. In this context, a survey of the needs and expectations of the people to which the museum is dedicated plays a major role for the changes planned to prove successful. Teachers are among the main users of the museum, staying at the core of all teaching-learning processes, and play a role as mediators between science and students. This paper analyses the judgements made by teachers about various types of events and teaching resources which are normally provided by science museums and, more specifically, the Science Museum of Castilla-La Mancha. Against that backdrop, science (our content), education (our objective) and the democratic participation of teachers will show a clear route to follow if one wants to achieve quality for our institution and its future events.

Near the turn of the Century, a woman in her 90s from Dodge City, Kansas was riding her horse near the Pecos River and she described it as a sea of saltgrasses...You had to be very close to the river to see it because the grass was so high You could drink the water out of the springs in this area. I used to ride down to the Pecos River on horseback...There was a lot more water in it back then. We grew cantaloupes...and people were amazed at how sweet they were... We stopped because the water [became] was too salty. In 1903, fresh watercress and ferns were growing at Independence Springs [on the Lower Pecos River]...and there were pools of catfish and silver bass. Residents along Independence Creek sold minnows and other bait fish they took from the river. We had a terrible flood in 1941 and 1942 which breached Zimmerman Dam. The river at some places was 10 miles wide. Floodwater covered the valley and the dam was washed out. It seems there is always less water in the Pecos than we need... I think the water quality is worse now-- not that the Pecos River was ever beautiful and clear. When my grandfather got here 110 years ago, they had a lot of water problems then. The prospect of fixing the saltcedar problem and making this area come back the way it was 100 years ago looks bleak for to me...I don't know if we can do that --Quotes from long-time residents of the Pecos River of Texas

This article introduces a study on the websites of several European public research institutions that aims at identifying the science communication model chosen and implemented online with the purpose of reaching different target publics. The analytical approach takes into account a number of indicators: from the institutional identity to the scientific features, from the interactive services to the internationalisation level, in order to evaluate whether the web provides an added value in the adopted communication model and in building a relation with the users. Lights and shades emerge from this study in which good practices side examples of a much weaker science communication approach, outlining a general context where a public research institution website has been still used as a presentation tool and its interactive opportunities have not been capitalised.

The first step of the SEDEC project has been a survey on teachers and pupils perception of science, scientists, and the European dimension of science. Different research actions have been organized for the different targets, and have been held in the six countries involved in the project: Czech Republic, France, Italy, Portugal, Poland and Romania. This article will present the results of a questionnaire distributed between European teachers. A research on the scientific imagery should have an opposite perspective to the one of a teacher at school; whereas the latter, the keeper of a knowledge, has the usual task of transferring and checking the knowledge in their students, a researcher has to record and describe their interior world relating to science – the information, but especially the images, the expectations, the emotions related to it.

In 2007 the Life Long Learning Programme (previously Socrates) of the European Commission has started. The programme offers to teachers, educators and policy-makers of the education sector the opportunity to be funded for participating at various training courses organized in all EU countries by international networks and projects. The SEDEC course will be included in that list in 2008. The article shortly present how to ask for a grant.

If one of aims of science today is to respond to the real needs of society, it must find a new way to communicate with people and to be acquainted with their opinions and knowledge. Many science museums in Europe are adopting new ways to actively engage the public in the debate on topical scientific issues. The Museum of Science and Technology "Leonardo da Vinci" in Milan (partner of the SEDEC project) has thus experimented some formats for dialogue with teachers and with the public in general. Our experience shows that museums can be places where science and the public on the one hand and democracy on the other meet.

IUFM is a centre for the in-service training of teachers and the development of didactic research. IUFM contribution to the SEDEC project is essentially built on a reflexion on educational implications of the links between science and European citizenship. We are convinced that European citizenship may be developed in scientific activities in school, by the introduction of communication moments, where pupils have to express and defend their ideas, and also to understand and accept the others’ ones. We have implemented two activities using the results of the SEDEC survey on science perception, that make the pupils get a better view on scientific research, especially in the knowledge of two scientific “jobs”, astronomer and botanist. Our approach consists of allowing the children express their conceptions of these jobs, of organising a debate to clarify these ideas, and of confronting them with other pupils’ opinions in Europe, with the history of the involved science and with direct testimonies of scientists. The project should be pursued in allowing classes in Europe to communicate about a scientific problem and so, to live their European citizenship.
