The Química Nova Interativa (QNInt) portal was launched in 2009 by the Brazilian Chemical Society (SBQ) to offer free quality content for broad audiences. QNInt provides peer-reviewed articles from SBQ journals on science & society, chemical concepts, classroom activities and educational research. With 3,000,000 visits, QNInt also offers a unique library of interactive molecules. In the International Year of Chemistry QNInt served for distributing pH kits and registering data from IUPAC's Global Water Experiment, yielding Brazil the largest share of the global pH data set. The portal performance makes QNInt a valuable resource for connecting science to education.
Visualization is a fast-growing field in science education. This review covers 171 articles published between 2001 and 2010 in 14 science education journals. Major findings include: i - despite the predominance of English speaking countries, interest in the topic has increased in several countries; ii - qualitative research is increasing, but quantitative methodologies prevail; iii - the role of peer interaction in group activities is little investigated; iv - research on the way students and teachers use visualization tools is increasing, but most publications focus on the tools; v - structure of matter remains the most common subject covered.
Chemical knowledge plays a central role in the economical and social development of a nation. Chemistry is considered a key science, which provides the means and meanings that fuel the advancement of other fields of knowledge. However, the public image of chemistry is often associated with negative facts and misconceptions. This paper addresses and discusses the public image of chemistry with two case studies: the public image of chemistry depicted in two major Brazilian newspapers and the Brazilian project for the International Year of Chemistry (IYC). Analysis of the newspaper data strongly suggests that the public image of chemistry is related to both the way news is written and the ability of the reader to identify the chemical knowledge actually present in the text. Analysis of IYC related data in the second case study depicted an optimistic panorama for the divulgation of chemistry at both national and local levels. A model for broad and effective initiatives for dissemination of chemistry is discussed. The need to keep science divulgation as the top agenda of the scientific community is also highlighted.
