The characteristics of interaction and dialogue implicit in the Web 2.0 have given rise to a new scenario in the relationship between science and society. The aim of this paper is the development of an evaluation tool scientifically validated by the Delphi method that permits the study of Internet usage and its effectiveness for encouraging public engagement in the scientific process. Thirty four indicators have been identified, structured into 6 interrelated criteria conceived for compiling data that help to explain the role of the Internet in favouring public engagement in science.

The history of public communication of science in Spain is yet to be written. Few academic studies exist that have tackled this subject. The political and economic history of the country have marked out the evolution of this discipline, which burst into the country at the end of the 20th century with the proliferation of initiatives such as the creation of science museums, the building of the Spanish Science Foundation and the development of a public Scientific Information service. Despite these efforts, the level of scientific culture for Spanish people is one of the lowest in Europe [OECD, 2016].
