Training teachers at the science centre or at the science museum is not always easy. Teachers are one of the main protagonists in schools (the other one are the students!) and they are the ‘specialists’ of teaching. Furthermore, very often they are discipline specialists too. Is this maybe too much for a nice, pleasant, spontaneous, interesting, interactive science expert or guide of the museum or of the centre? In science centers and museums the real protagonist is the public, and we wish ourselves more expert in communication than in sciences. Than, how to touch the world of the school, how to influence the everyday activity of these school protagonists, how to change their mind on what has to be taught, how it has to be taught, what has to be evaluated and how it has to be evaluated? This session will open with three short demonstrations involving the public about what is possible to do with teachers for training them: 1) SCIENCE CENTRES: INSTRUCTION FOR USE. Science centers are privileged places for learning. In these places teachers can get a new dimension since they can offer a unique and multisensory experience. But teachers must know how to use them! The training of teachers allows both museum professionals and teachers to explore pedagogical materials, exhibits and other resources, practice ways of engaging and discuss how to improve the learning process of their students. 2) THE INVISIBLE MAN. Refraction laws experienced through the narration of a science fiction novel. Listening the Griffin’s words, the main character of the novel “The invisible man” (1897) written by H.G. Wells, it will see that a piece of glass will disappear, a sheet of paper will become transparent… This with the aim to involve and attract teachers to teach physics in a new way. 3) A DELICATE NET FOR LIFE. It is comprehensible for most people that small herbs manage to transport water from the roots to the tips of their leaves. But it is far more impressive that this same technique apply for a distance of over 100m found in Giant Sequoya trees. The vascular system of plants terminates in a net of veins composing the leaf skeleton. Preparing a leaf skeleton is used to lead teachers into investigating one central phenomenon in plant life – the transport of water. Have a close look at this fascinating transport system and prepare your own delicate net of life. After this practical introduction, the session will continue with a large discussion about ideas and experiences of all the participants. The best teacher training course at the science centre will be planned at the end!
