When serial neurocognitive assessments are performed, 2 main factors are of importance: test-retest reliability and practice effects. With children, however, there is a third, developmental factor, which occurs as a result of maturation. Child tests recognize this factor through the provision of age-corrected scaled scores. Thus, a ready-made method for estimating the relative contribution of developmental versus practice effects is the comparison of raw (developmental and practice) and scaled (practice only) scores. Data from a pool of 507 Portuguese children enrolled in a study of dental amalgams (T. A. DeRouen, B. G. Leroux, et al., 2002; T. A. DeRouen, M. D. Martin, et al., 2006) showed that practice effects over a 5-year period varied on 8 neurocognitive tests. Simple regression equations are provided for calculating individual retest scores from initial test scores. (Contains 4 tables, 2 figures and 1 footnote.)

This article reflects the 17 years of experience of the "Entreculturas project" in Portugal, where the "Learning to live together" dimension has played a central role. It questions how intercultural education and training can contribute to promote and model an intercultural citizenship societal project and looks back at the history of the Entreculturas process in two different settings: (1) within the Ministry of Education (1991/2003), aimed at building and developing intercultural education in the educational system; and (2) at present, within the ACIDI--High Commission for Immigration and Intercultural Dialogue--"upgraded" into a broader transversal dimension of immigrants' integration public policy.

This paper describes the monitoring system of the urban quality of life developed by the Porto City Council, a new tool being used to support urban planning and management. The two components of this system--a quantitative approach based on statistical indicators and a qualitative analysis based on the citizens' perceptions of the conditions of life--are presented. The strengths and weaknesses of these two approaches adopted in the project are reviewed. It is argued that, in order to achieve a deeper understanding and more effective measurement of urban quality of life, both kinds of measurements are useful and complement each other.

Sex education in Portugal has become a right and an obligation starting in the first years of school. However, despite being required by legislation, this is not easy to achieve, partly because of weaknesses in the training of teachers, which need to be identified. In this study, data were collected about the knowledge, behaviours and beliefs of 148 teacher trainees of elementary education (6-10 years old) from two Portuguese public higher education institutions. The topic of sexuality and human reproduction had been covered by almost all of them during their initial training and was considered important by most of them. Nevertheless, about 85% asserted they are not confident enough to teach this topic to small children in a classroom and committed scientific errors about physiological-anatomical aspects of the human body. All subjects felt that there is a lack of specific didactic materials, which does not help to overcome those obstacles. It was also possible to identify in these future teachers risky sexual practices resulting, in part, from their beliefs, which could have implications about the way the topic will be approached in the classroom. These findings show how essential it is for training institutions to pay greater attention to the education of future elementary school teachers in this area. (Contains 4 notes.)

Argues that science education is a fundamental tool for global education and that it must be introduced in early years as a first step to a scientific culture for all. Describes testing validity of a didactic strategy for developing the learning of concepts, which was based upon an experimental work approach using everyday life contexts. (Author)
