The enigma of cosmic rays-2     

Biman Nath 《Resonance》2007,12(11):44-53

Part 1¹ of the article discussed the discovery and observed properties of cosmic ray particles. These energetic particles are produced during violent astronomical events. We discuss possible sources of cosmic rays detected on Earth in this article. Supernovae explosions of dying stars are believed to produce cosmic rays with low energy. The detection of ultra-high energy cosmic rays is however difficult to explain. On one hand, they must originate outside our Galaxy and on the other, the cosmic microwave background radiation pervading the universe makes it difficult for them to travel large distances in intergalactic space. So, they must be produced in the neighbourhood of our Galaxy, but are there enough energetic phenomena taking place in this region of the universe?

A programme for future audit professionals: using action research to nurture student engagement     

Karen Van Peursem  R. Helen Samujh  Nirmala Nath 《Educational Action Research》2016,24(4):598-616

Professionals require decision-making skills as well as technical knowledge. One might assume that their university education prepares them for this role yet, and least for future audit professionals, traditional text – and lecture – methods dominate teaching practice. This Participation Action Research study develops with auditing students a practice-informed, computer-based and judgement-orientated learning programme. We seek to identify ways in which student engagement in such decision-making dilemmas can be created and improved. Logs, student-surveys and notes from an independent observer document the longitudinal process. Findings identify features that improve student engagement and a contribution of the project is in revealing the value of removing technical and in-class social barriers. Implications for nurturing higher-level learning and for serving professional curriculums generally conclude the study.  相似文献

The role of pre-school education on learning achievement at primary level in Bangladesh     

Samir Ranjan Nath 《International Journal of Early Years Education》2012,20(1):4-14

This paper examines the impact of pre-school education on learning achievement at primary level in Bangladesh. Evidence from learning achievement test and household and school-related data were obtained from 7093 pupils attending 440 primary schools in Bangladesh. Findings suggest that a small proportion (15.3%) of primary school pupils attended pre-school. Pupils from educated parents and well-off families were more likely to attend. In principle, however, attendance at pre-school did not predict later learning achievement at primary level, but a range of socio-demographic, school-related and additional educational factors did have an impact. It is concluded that further research is warranted to examine the quality of pre-school provision offered in Bangladesh and the qualifications of professionals working with young children in these centres.  相似文献   

Savouring Rajasthan's Shiksha Karmi in a remote village: the prospect of dismantling the student-teacher divide     

Brij Kothari  P. G. Vijaya  Sherry Chand  Rajeev Sharma  Amar H. Kalro  Parvinder Gupta 《International Journal of Lifelong Education》2013,32(5):407-417

The Shiksha Karmi Project in Rajasthan, one of the most educationally challenged states, is at the frontiers of alternative models of primary education in India. The key ideas underlying this model are: (i) the taking over of ‘sick’ schools in remote regions of the state and turning them around, (ii) creating new schools driven by demand from the ground, (iii) human resource investments to train local village teachers, (iv) strong linkages between the school and the community built upon a spirit of voluntarism, (v) an explicit movement toward gender equity and (vi) a bold attempt at the universalization of primary education through a combination of formal and non-formal institutions. This article provides a grounded feel for the Shiksha Karmi Project in a stellar school, Meena Dant Ka Pura. While the case highlights the shortage of locally based female teachers in the entire Shiksha Karmi Project, it also suggests the very real possibility of employing Shiksha Karmi Project alumni and higher grade students in teaching roles. Overall, primary education in India has much to learn from the Shiksha Karmi Project experience.  相似文献   

Dust in space     

Nath  Biman 《Resonance》2003,8(1):15-29

Dust grains in space, which absorb and redden starlight, were once considered to be a nuisance for astronomers, but the study of dust has become important in modern astrophysics. A few interesting characteristics of these dust grains are discussed here.  相似文献
