Este é um artigo publicado em acesso aberto (Open Access) Resumo: Neste estudo, analisamos como temas de C&T são veiculados na emissora de TV aberta de maior audiência no Brasil, a TV Globo. Gravamos e analisamos uma amostra de duas semanas construídas (14 dias), representativas de um período de seis meses de 2013, totalizando 336 horas assistidas na íntegra. Pela análise de conteúdo, observamos que a ciência esteve presente em 7,3% da programação da emissora no período analisado e perpassou por várias categorias televisivas, desde telejornais a publicidades, de telenovelas a talk shows. A ciência esteve ligada, em grande medida, a questões de Medicina e Saúde. Cientistas e especialistas foram fontes de informações importantes sobre tais assuntos, assim como os cidadãos. Contudo, foi reduzida a presença da figura do cientista nas peças -e, quando presente, havia mais homens do que mulheres cientistas. As publicidades foram a categoria televisiva mais frequente em nosso corpus e, nelas, a ciência foi utilizada como um recurso para dar credibilidade ao produto, evidenciando o papel legitimador da ciência.Palavras-chave: divulgação científica; ciência na TV; TV Globo.Abstract: Science and Technology in Brazilian TV: an analysis of Globo TV programing -In this paper, we analyze how S&T issues appears on the TV Globo, the channel with the largest audience in Brazil. The methodology of "constructed week" was used to compose a sample of two weeks (14 days), representative of six months in 2013. We recorded and watched each day, a total of 336 hours. Through a content analysis, we found out that science appeared in 7.3% of TV Globo broadcast during the period analyzed and was in several television categories, from TV news to advertising, from soap operas to talk shows. Science was more related to issues of Medicine and Health. Scientists and experts were important sources of information,

The social interactions that take place in science museums, whether between family members or with mediators, are recognized as essential to visitors’ experience. However, there is still little empirical research in the Brazilian context on how families interact and converse on visits to science museums – and even less on the role of the mediator in the museum experience. In this exploratory study, the authors analyze the social interactions of families in an interactive exhibition on biodiversity: “Forest of the Senses”, at the Museum Science and Life (Brazil), characterized by having one of the lowest human well-being indicators in the country. In particular, the authors analyzed the ways in which the presence of human mediation influenced the experience of family visits to the exhibit. Video and audio of ten low-income families' visits were recorded and analyzed using a protocol based on social interactions that take place in museums. Results show that human mediation did not influence the amount or types of visitor-exhibit interactions or the amount of time spent at the exhibit, but increased the amount of conversation time among the groups, including the amount of time discussing science content, thus providing insights into mediator training and qualification.

In this study, we analyse the role of emotion in the context of informal science education experiences, specifically seeking to understand: (a) which emotions can be stimulated in families visiting interactive expositions, and (b) the extent to which parents/caregivers and museum explainers engage the children's emotional expressiveness. To this end, a protocol based on the core affect model was employed to examine the visits of 10 family groups (26 individuals) who visited an exhibit on biodiversity in a science museum in Rio de Janeiro, Brazil. Five families went on free visits and the other five had their visits mediated by explainers. We observed that, in general, positive emotions, such as excitement and surprise, were among those most often expressed. Negative emotions, such as disagreement and doubt, also stood out in this study, but they were not exclusively associated with the negative aspects of the experience, and were instead linked to challenging moments that facilitated the construction of meaning by the families. The data suggest that visits mediated by explainers occasioned more frequent emotional displays than free visits, indicating the importance of explainers in families’ interactions and emotional responses.
