The Promises and Perils of Nanoscience and Nanotechnology: Exploring Emerging Social and Ethical Issues

Rapid advances in nanoscience and nanotechnology are profoundly influencing the ways in which we conceptualize the world of the future, and human ability to manipulate matter at the atomic and molecular levels offers previously unimagined possibilities for scientific discovery and technological applications. The convergence of nanotechnology with biotechnology, information technology, cognitive science, and engineering may hold promise for the improvement of human performance at a number of levels. Based on a National Science Foundation-funded Research Experiences for Undergraduates Program in nanoscience and nanotechnology at the University of Central Florida (summer 2002), a variety of social and ethical issues associated with these advances is discussed. Implications for the future of science-technology-society studies and K-16 science education also are presented.

Theory-Based Interventions for School Children Cared for by Their Grandparents.

The growing social phenomenon of grandparents caring for their grandchildren has implications for educational psychology practice, since children who are wards of their grandparents frequently experience problematic school functioning. In this paper, the literature regarding children cared for by grandparents is reviewed. Issues concerning attachment, social support, and the children’s school‐related functioning are emphasised. In addition, theoretical and practical school‐based interventions to help these grandchildren are described.

Developing a Laboratory Model for the Professional Preparation of Future Science Teachers: A Situated Cognition Perspective.

Although laboratory activities are widely acknowledged as being fundamental to the teaching of science, many secondary science school teachers have limited knowledge of how to design and run effective teaching laboratories. Utilising a situated cognition theoretical framework, we discuss our collaborative efforts to develop a laboratory based model for the professional preparation of secondary level science teachers. Findings from the study suggest that the learning which occurs in the laboratory context may be transferred (with appropriate modifications) to the secondary science classroom. Implications also are presented for science teacher preparation, ongoing professional development, and further study.

Nanomedicine concepts in the general medical curriculum: initiating a discussion

Various applications of nanoscale science to the field of medicine have resulted in the ongoing development of the subfield of nanomedicine. Within the past several years, there has been a concurrent proliferation of academic journals, textbooks, and other professional literature addressing fundamental basic science research and seminal clinical developments in nanomedicine. Additionally, there is now broad consensus among medical researchers and practitioners that along with personalized medicine and regenerative medicine, nanomedicine is likely to revolutionize our definitions of what constitutes human disease and its treatment. In light of these developments, incorporation of key nanomedicine concepts into the general medical curriculum ought to be considered. Here, I offer for consideration five key nanomedicine concepts, along with suggestions regarding the manner in which they might be incorporated effectively into the general medical curriculum. Related curricular issues and implications for medical education also are presented.
