Effective training in key communications skills is critical for successful public engagement. However, what are the secrets to designing and delivering an effectual training course? This paper outlines key findings from a research study into communication training programmes for public engagement with STEM (science, technology, engineering and mathematics). The research focused on training in direct communication methods, (as separate from media training) and encompassed both trainers and trainees, the latter group spanning across both scientists and explainers. The findings indicated that training courses are effective at increasing involvement in science communication events and trainees feel more confident and able to engage due to training. An interactive style was found to be a key element of training courses. Demonstrations of good practice followed by own performance with feedback were also important, preferably involving a ‘real’ audience. A list of guidelines on best practice has been developed which offers practical advice.

This article presents an example of how a public science party was evaluated. The main goals of the science party, to increase the positive image of science and present an attractive science event, were evaluated in two ways. First, web surveys were used to determine the image of science before and after the event among paying visitors, invited guests, and a control group (N = 149). Second, during the event, visitors were interviewed about their experiences at the event (N = 124). The survey study showed that the image of science was very positive among all three groups of respondents. As no differences were found between pre- and post-tests, participation in the event did not lead to a more positive image of science. The results of the interviews suggested that visitors highly appreciated the event. In the Discussion, the evaluation study is analyzed and possibilities/limitations for future general use are discussed.

Dialogical models in science communication produce effective and satisfactory experiences, also when hard sciences (like astrophysics or cosmology) are concerned. But those efforts to reach the public can be of modest impact since the public is no longer (or not sufficiently) interested in science. The reason of this lack of interest is not that science is an alien topic, but that contemporary science and technology have ceased to offer a convincing model for the human progress.

The practice of dialogue does not erase the conflicts that can be found upon solid diverging interests. But conflicts are not forcedly a trauma. More then an impossible abolition of diversity, it is important to promote a practice that helps everybody to express their own point of view looking for socially sustainable solution between the parts. But according to Sturloni, «Even in that case: not a dialogue meant to achieve a utopian unitary view able to level all divergences, but to allow the expression of different perspectives and of legitimate interests. The final aim should be to make a choice shared as much as possible within the legal system of a democratic country».

What is the meaning of “dialogue” in education? Why is dialogue important in learning processes? Tran proposes a short review of the literature, starting with Vygotsky and ending with a new field of research in informal learning - conversations among the public visiting museums as a collaborative environment for learning.

To give a good public speech is art; but definitely more difficult is to organize a productive exchange of points of views between scientists, experts, non-experts and policy-makers on controversial issues such as a scenario workshop or a consensus conference. Many skills and a deep knowledge both of the topic and of the methodology are required. But this is the future of science communication, a field where the dialogical model will impose new and complex formats of communication and a new sensibility, using also the most traditional media. But are science communicators prepared for that? What is the state of the art of science communicator training?

“Dialogue” is the trendy word of the moment. The word “dialogue” can be found in the call to access European funding, in the works of Science Communication scholars, in presentations of science education projects, in the mission of new science centres. “Dialogue” is also a word reported by mass media regarding politicians' and scientists' speeches on general issues as well as on local or specific problems such as environment, health, energy, etc... This new magic word is frequently repeated and opens many doors (or perhaps it simply helps to make a good impression). However, there is the risk of ignoring the real meaning and functioning of the word. JCOM is therefore asking a number of experts involved in “dialogue” the following questions: what does it really mean? What are the theoretical principles, the practical opportunities, but also the risks and limits of “dialogue”?

Science musums and science centres are wonderful places to host, support and mediate the dialogue between science and society. In fact, they are a natural crossroad where scientists, general public, media and insitutions for formal and informal learning meet. During the recent political and health crisis concerning the rubbish treatment in the Italian region of Campania, the science centre "Città della Scienza" has promoted an unusual dialogue between citizens and scientists.

Dialogue in science communication is a necessity - everybody agrees on it - because science and technology issues are involved in so many aspects of the citizens life, and in so many cases can raise suspects, fears, worries or, on the contrary, expectations and hopes. But who are the possible interlocutors for scientists and policy-makers? Everybody, says Luisa Massarani, beginning with children and teenagers. Also in such controversial and sensitive issues like AIDS or GMO.

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
