    Our research objectives focussed on monitoring (i) students' activities during experimental teaching phases in an out-of-school gene technology lab; (ii) potential relationships with variables such as work group size and cognitive achievement. Altogether, we videotaped 20 work groups of A-level 12th graders (N = 67) by continuous recording of their lab-work phases. Subsequent analysis revealed nine categories characterizing the students' most relevant activities. Intra- and inter-observer objectivity as well as reliability scores confirmed the good fit of this categorization. Based on the individual time budgets generated, we extracted four clusters derived from students' prevalent activities. A cross-tabulation of two cluster analysis methods independently used showed a high level of agreement. Clusters were labelled as (i) 'all-rounders' (members of which applied similar portions of time to the main activities), (ii) 'observers' (members' dominating activity focussed on in-group observation of the lab-work), (iii) 'high-experimenters' (members predominantly engaged in specific hands-on activities), and (iv) 'passive students' (members mainly engaged in activities with no experimental relation). Particularly, we found members of clusters 1 and 2 in four-person work groups while members of clusters 3 and 4 were prevalent in three-person groups. During the educational intervention, students of all clusters improved their cognitive achievement on a short-term and a long-term schedule. However, only the 'all-rounders' revealed a high level of persistent (long-term) knowledge with no decrease rate at all. We draw conclusions with respect to work group sizes as well as to organisational aspects of experimental lessons

    Our article analyses science-technology- society-environment (STSE) issues in the genetics-related chapters of Portuguese natural sciences and biology textbooks and considers how they contribute to students’ scientific literacy. We inspected manner of imparting of the decontextualized and socially neutral view of science and technology (S&T) as an obstacle for achieving scientific literacy. Our sample comprised four textbooks, two for the 9th and two the 12th grades. We identified and content-analytically analyzed 1019 STSE statements with regard to their compliance with previously proposed criteria. We quantitatively analyzed the statements’ frequencies. We noted an attempt to approach STSE issues, but we found important deficiencies in all the textbooks, as well as indicators of a distorted view of science. We discuss possible influences of the socio-cultural context in the selection of STSE contents, in the terms being applied, as well as in the S&T conceptions displayed by the textbooks.O nosso artigo analisa o tema das relações entre a ciência, a tecnologia, a sociedade e o ambiente (conhecidos na língua inglesa como STSE issues), nos capítulos relacionados com a genética, em manuais de ciências naturais e de biologia, e considera em que medida eles contribuem para a literacia científica dos alunos. Adicionalmente, foi averiguada a transmissão da visão descontextualizada e socialmente neutra da ciência e da tecnologia, enquanto obstáculo à literacia científica. A amostra compreende quatro manuais portugueses de Biologia e de Ciências Naturais, nomeadamente, dois para o 9.º ano e dois para o 12.º. Identificámos e analisámos 1019 expressões com conteúdo STSE, conformes com critérios previamente propostos, e procedemos à análise de frequências. Verificou-se uma tentativa de abordagem de conteúdos STSE, tendo sido também detetadas deficiências importantes em todos os manuais, assim como indicadores daquela visão distorcida da ciência e da tecnologia. Discutem-se ainda possíveis influências do contexto sociocultural na seleção dos conteúdos STSE, nos termos utilizados, bem como na conceção sobre ciência e tecnologia refletidas nos manuais

    Studies on the Schismatoglottideae (Araceae) of Borneo VI : A New Schismatoglottis Species from Sarawak, Malaysian Borneo

    Fieldwork in Sarawak continues to reveal further novelties in the genus Schismatoglottis Zoll & Moritzi, notably in the Asperata and Multiflora Groups (sensu Hay & Yuzammi, 2000). The second author collected a new Schismatoglottis species in Sarawak belonging to the Multiflora Group. This is here described and illustrated and included in additions to the key to Bornean Schismatoglottis published by Hay & Yuzammi (2000)

    Arum megobrebi is described as a new species of A. subg. Arum from NE Turkey and central S Georgia and illustrated. It takes to 29 the number of species currently recognised for the genus. It is closely related to but easily distinguished from A. maculatum by, in particular, its elongate-cylindrical appendix of the spadix
