Developing latent mathematics abilities in economically disadvantaged students

This Javits grant evaluation study sought to develop latent abilities in economically disadvantaged students by providing opportunities for mathematics development and acceleration. This study examined the effects of Kumon instruction, a supplementary, highly sequential, individualized method of developing mathematics skills. Whole classes of Title I elementary school students from grades two through five were divided into two groups, those with Kumon instruction and those without. All students continued with traditional textbook mathematics. Pre‐and posttests were administered to all participants to assess progress, compare standardized test results, and examine levels of acceleration. Results showed that Kumon group students improved their mathematics skill levels more than non‐Kumon group students, and they scored significantly higher than non‐Kumon group students two years after their Kumon instruction ended.     

Stand by me: The effects of peer and teacher support in mitigating the impact of bullying on quality of life

Bullying is one of the most common forms of school violence. Engagement in bullying has been shown to have adverse effects on perpetrators and victims of bullying. In this study, the impact of bullying on well‐being (quality of life/life satisfaction) was explored in a sample of elementary and middle school children (N = 4,331). Results suggest that students who bully and/or are bullied experience reduced life satisfaction and support from peers and teachers compared to “bystanders” (children who are neither victims nor perpetrators of bullying). Mediational analyses demonstrate that peer and teacher support might mitigate the impact of bullying on the quality of life of victims. This study underscores the value of efforts to promote social support from peers and teachers in both universal bullying prevention programs and school climate initiatives. Furthermore, results support further investigation into the possible contributions of bystanders in supporting school‐wide bullying prevention/school climate strategies. © 2009 Wiley Periodicals, Inc.     

(Re-)designing higher education curricula in times of systemic dysfunction: a responsible research and innovation perspective

There is an urgent need to address the grand sustainability challenges of our time, and to explore new and more responsible ways of operating, researching, and innovating that enable society to respond to these challenges. The emergent Responsible Research and Innovation (RRI) policy agenda can act as a catalyst towards the development of new and more responsible research and innovation efforts. Inevitably, higher education needs to be closely attuned to this need and agenda, by preparing students to engage in RRI efforts. This paper makes a first step towards guiding the embedding of RRI within higher education. It does so by bringing together academic knowledge with phronesis or practical knowledge about what should be done in an ethical, political, and practical sense. It draws on a literature review and on the reflective practices of partners in the European Commission funded project EnRRICH (Enhancing Responsible Research and Innovation through Curricula in Higher Education), as well as on interviews and case studies gathered as part of the project. The paper suggests elements, especially design principles and a competence framework, for (re)designing curricula and pedagogies to equip higher education students to be and to become responsible actors, researchers, and innovators in a complex world, and to address grand sustainability challenges. In addition, this paper proposes that contemporary higher education teaching and learning policies and strategies, especially those promoting neoliberal agendas and marketized practices, need to adopt a more responsible and responsive ethos to foster the renewal of higher education in times of systemic dysfunction.     

Writing groups as transformative spaces

Curriculum transformation is a central concern for higher education in response to rapidly expanding technologies, globalisation and the widening diversity of the student and staff body. This is particularly true for South Africa, which is still grappling with inequalities and pressure for social redress in its universities. Early responses to supporting students took the form of add-on, ‘deficit-model’ approaches which understood poor student retention and success rates as emerging from students’ lack of neutral literacy ‘skills’. Recent initiatives have begun to adopt more socio-cultural understandings of literacy that seek to challenge traditional power structures and cultivate horizontal peer-orientated spaces for learning with a focus on practice rather than on product. Writing groups, as spaces for academic writing development, embrace this orientation and are argued to provide a transformative framework that foregrounds proactive student learning and experience, while still accommodating disciplinary learning through peer engagement. Drawing on the successful implementation of such forms of support at a research-intensive university, this paper argues that writing groups can play a critical role in both personal (student) transformation and broader curriculum transformation. Data include anonymous questionnaires and surveys with participants and coordinators of the writing groups. An inductive, constant comparative analysis indicated that students feel empowered in this space to develop not only their writing practices but also their transforming identities as scholars. Writing groups were found to provide ‘safe spaces’ where academic practices can be made explicit and where they can be challenged. The paper therefore argues that writing groups can play a small but key role in broader transformation efforts.     

Effect of glucose polymer ingestion on energy and fluid balance during exercise

Nine male triathletes were studied during 160 min of exercise at 65% VO2 max on two occasions to examine the effect of glucose polymer ingestion on energy and fluid balance. During one trial they received 200 ml of a 10% glucose polymer solution at 20 min intervals during exercise (CHO), while in the other they received an equal volume of a sweet placebo (CON). On average, blood glucose levels (CON = 4.2 +/- 0.2 mmol l-1, CHO = 4.8 +/- 0.1, mean +/- S.E.) and respiratory exchange ratios (CON = 0.84 +/- 0.01, CHO = 0.87 +/- 0.01) during exercise were higher (P less than 0.05) as a result of the glucose polymer ingestion. There were no differences between trials, however, in the estimated plasma volume changes during exercise. Exercise time to exhaustion at an intensity corresponding to 110% VO2 max, performed 5 min after the submaximal exercise, was not influenced by glucose polymer ingestion. Relative to a control exercise bout conducted without prior exercise, however, sprint performance and postexercise blood lactate accumulation were impaired in both trials. It is concluded that glucose polymer ingestion maintains blood glucose levels and a high rate of carbohydrate oxidation during prolonged exercise, without compromising fluid balance.     

A novel approach to London: Infusing ethnography and the study abroad experience

Courses: Qualitative Research Methods, Ethnographic Research Methods.

Objective: This purpose of this activity is to document the enculturation process through which students begin to understand a new culture during a study abroad experience. To accomplish this, we created a new pedagogical approach for study abroad experiences that involved a combination of academic and fictional readings to help students make sense of and perform ethnographic research techniques.
