Effective practices for creating transformative informal science education programs grounded in Native ways of knowing

There are a growing number of informal science education (ISE) programs in Native communities that engage youth in science education and that are grounded in Native ways of knowing. There is also a growing body of research focusing on the relationship between culture, traditional knowledge, and science education. However, there is little research documenting how these programs are being developed and the ways in which culture and Western science are incorporated into the activities. This study outlines effective practices for using Native ways of knowing to strengthen ISE programs. These effective practices may also be used to promote change in formal education. The authors combine an overview of current research in informal science education with personal interviews with educators engaged in ISE programs offered to youth both on and off tribal reservations as well as experts in Indigenous education. Participating individuals and programs included Native communities across the United States, including Alaska and Hawai??i. Keeping in mind that each community is unique, ISE programs that are grounded in Native ways of knowing will benefit by utilizing the effective practices outlined here as a guide for starting or strengthening existing ISE programs relevant to the needs of their communities.     

Mediating third-wave feminism: appropriation as postmodern media practice

In this essay, we explore how sensibilities of third-wave feminism are appropriated by and in the context of postmodern media such that they are commodified, reinscribed, and sold to audiences in an hegemonic fashion. To this end, we analyze gendered representations of women located at various mediated sites of popular culture in whom gender is conspicuous and primary: Alanis Morissette, Kate Moss, and Ally McBeal. We argue that, in each case, the appropriation of third-wave feminist tenets is accomplished via a postmodern aesthetic code of juxtaposition that serves to recontextualize and reinscribe those sensibilities in a way that ultimately functions to reify dominant patriarchal codes and discourses.     

‘Peer social capital’ and networks of migrants and minority ethnic youth in England and Spain

This article discusses friendships and peer groups of migrant and minority ethnic youth in schools in England and Spain, and critically considers them in relation to existing notions of ‘peer social capital’ and bridging (heterogeneous) and bonding (homogeneous) peer networks. The article argues for an extended understanding of peer social capital and discusses the complex composition and outcomes of bridging and bonding peer networks. It critically discusses both facilitators and barriers to friendships experienced by migrant and minority ethnic youth in schools, and considers them in relation to school practices.     

THE IMAGE OF PUBLIC OPINION SURVEYS IN BRITAIN AND FRANCE

This paper examines the results of studies in Britain and Franceon the views of the two peoples towards public opinion surveys: — their experience of surveys — attitudes towards the concept of sample surveys — the accuracy of sample surveys — the publication of polls during election campaigns — exposure to news information — interest in survey data The results in the two countries were, to a substantial degree,similar and showed an underlying positive attitude towards publicopinion surveys. There are, however, a number of points to bearin mind, where more public relations and more public informationis required to improve public awareness of, and public acceptanceof, opinion surveys.     

Microfluidic concentration of bacteria by on-chip electrophoresis

In this contribution, we present a system for efficient preconcentration of pathogens without affecting their viability. Development of miniaturized molecular diagnostic kits requires concentration of the sample, molecule extraction, amplification, and detection. In consequence of low analyte concentrations in real-world samples, preconcentration is a critical step within this workflow. Bacteria and viruses exhibit a negative surface charge and thus can be electrophoretically captured from a continuous flow. The concept of phaseguides was applied to define gel membranes, which enable effective and reversible collection of the target species. E. coli of the strains XL1-blue and K12 were used to evaluate the performance of the device. By suppression of the electroosmotic flow both strains were captured with efficiencies of up to 99%. At a continuous flow of 15 μl/min concentration factors of 50.17 ± 2.23 and 47.36 ± 1.72 were achieved in less than 27 min for XL1-blue and K12, respectively. These results indicate that free flow electrophoresis enables efficient concentration of bacteria and the presented device can contribute to rapid analyses of swab-derived samples.     

The competencies needed for teaching hearing-impaired students. A comparison of elementary and secondary school teacher perceptions

Many hearing-impaired students demonstrate difficulty in academically measuring up to their hearing peers. The deficiencies become especially obvious during their secondary school years. This study surveyed a national sample of elementary and secondary level teachers of the hearing impaired to compare their perceptions of the competencies needed to work with hearing-impaired students. The results suggest that teachers at both levels believe that some skills are fundamental for all teachers of the hearing-impaired, regardless of the age level of the students. However, the data also suggest there are some important differences. Concerns about state certification procedures and current practices in teacher training programs are discussed.
