OECD测度生物技术产业的方法

生物技术是重要性迅速增强的一个技术领域，对于健康、农业和食品等领域有很强的潜在影响。OECD成员国认识到有必要进行可靠的测度，着手建立“积木”式的统计框架。从2000年到2004年，一个生物技术统计框架已经建立起来。本文讨论该框架中的一些重要问题。     

Exploring practicum: student teachers’ social capital relations in schools with high numbers of pupils living in poverty

The complexity of practicum in initial teacher education, in terms of the range of diverse social relations and differing school contexts, provides a challenge for teacher educators worldwide, aiming to guide and shape opportunities for student teachers learning to teach. This challenge is further compounded by societal problems linked to child poverty. Drawing from social capital theory, this paper explores the kinds of social relations that are currently associated with student teachers’ practicum experience in schools located in areas of social and economic deprivation or with significant proportions of pupils living in poverty. The paper brings to the surface types of social relations that are beneficial to mitigating the effects of poverty on educational outcomes. The case is made that practicum does not currently support the principles of social capital theory by enabling student teachers to develop an understanding of how to make connections, and develop the social relationships required to support positive educational outcomes for the children and young people in such contexts. Findings indicate that more effective ‘joint practice’ is required to better support student teachers’ professional learning.     

Young people’s expressed needs for Comprehensive Sexuality Education in Ecuadorian schools

This study analyses the expressed sexuality education needs of young people from Azuay, a region of Ecuador characterised by a large proportion of young people whose parents have migrated abroad, a group often considered at risk to developing of sexual health problems. Multi-stage stratified cluster sampling was used to recruit young people aged 11 and 19 years to the study. The expressed needs of participants were analysed in relation to gender, parents’ migratory status, age and geographical location. Survey findings revealed that young people expressed high needs with respect to the different components of Comprehensive Sexuality Education: gender roles, sexual and reproductive health, sexual citizenship, pleasure, violence, diversity and relationships. Ordinal regression analyses revealed few significant differences in relation to socio-demographic variables, which was surprising, in particular, with respect to the group of young people with migrating parents. Given the high levels of expressed needs, the findings carry important implications for the design and implementation of future sexuality education programmes.

The Equation, the Whole Equation and Nothing But the Equation! One Approach to the Teaching of Linear Equations

There exists an extensive range of research looking at the teaching and learning of linear equations, resulting in many papers highlighting a range of teaching approaches and illustrating a variety of significant cognitive problems and stumbling blocks to the learning of linear equations with understanding. Building on this literature, this paper presents some of the results of a case study which looked at the mathematics classroom of one particular teacher, Alwyn, trying to teach mathematics with meaning to less able pupils at secondary school level. Our interest here is those lessons which dealt specifically with the learning of linear equations, in which firstly a different approach was utilised and secondly many of the problems referred to in the literature were not present. We contrast this method with the teaching of linear equations to a variety of ability levels in several other classrooms that we have studied and we attempt through use of the Pirie-Kieren model, to analyse and account for the successful growth of understanding of the lower ability, year eight pupils in one particular classroom.     

The impact of globalisation on qualitative research in comparative and international education

This is a revised version of the 2003 British Association for International and Comparative Education (BAICE) Presidential Address delivered at the 7th Oxford International Conference on Education and Development. The processes of globalisation have been viewed by some as a major threat to the qualitative research tradition in education. Two main aspects of the impact of globalisation on qualitative research are addressed here. Firstly, it is argued that given the vital role of culture in mediating global policies at different levels, qualitative research still has a very important role to play. Secondly, it is argued that the knowledge and information revolution associated with globalisation has created an increasingly positivist climate that represents both a challenge for, and a challenge to, comparative education as it is currently conceived—particularly in the UK. This is illustrated by the growing international interest in systematic review methodology and its associated privileging of quantitative research strategies, such as randomised controlled trials, in evidence‐based policy.
