Web 2.0 technologies for learning: the current landscape – opportunities, challenges and tensions: supplementary materials

These supplementary materials accompany the report ‘Web 2.0 technologies for learning: the current landscape – opportunities, challenges and tensions’, which is the first report from research commissioned by Becta into Web 2.0 technologies for learning at Key Stages 3 and 4. This report describes findings from the commissioned literature review of the then current landscape concerning learner use of Web 2.0 technologies and the implications for teachers, schools, local authorities and policy makers

Standards in English education: An enduring historical issue

This article is available open access from the publisher’s website at the link below.This article closely examines the development of education in England, taking special account of educational standards — of the official measurable kind, but also the perceived kind — in the various sectors of education. It argues that, today, and in the past, the ‘problems’ associated with education standards mostly relate to a ‘long tail’ of underperforming schools serving urban areas and attended by relatively underprivileged children. At the other end of the scale, it is suggested that England’s leading schools, both in the public and private sectors, remain the subject of admiration. The same remains true of England’s leading, and typically oldest, universities, which occupy a more privileged position than institutions chartered in the relatively recent past. The article presents a story of persistent unequal educational opportunities over time, which, worryingly, does not seem to be improving in the second decade of the twenty-first century

Lightweight, broad-band spectrum analyzer

Spectrum analyzer, utilizing techniques similar to those used to classify energy levels of nuclear particles, is incorporated into electric field detector. Primary advantage is ability to perform qualitative broad-band frequency analysis over a large dynamic amplitude range with minimum weight and electrical power requirements

Employment at Will: The American Rule and Its Application in Alaska

In this thesis, secondary flow in a two stage, low aspect ratio turbine is investigated using CFD. A parameter study is carried out to investigate how the turbine performance is affected by the choice of aspect ratio. This is done in two steps, first by changing the blade height and then the blade size. The study shows that increasing the aspect ratio will lead to a significant increase of efficiency, but the effect diminishes for large aspect ratios, at which the efficiency moves towards an asymptotic value. Furthermore it is shown that increasing the aspect ratio to a certain value by changing the blade height results in a higher efficiency compared to changing the blade size, which is due to the difference in hub-to-tip ratio. An attempt to quantify the secondary losses is also made by looking at the radial kinetic energy at the outlet of a blade row. It turns out though, that the radial kinetic energy does not follow the same trend as the total pressure loss coefficient, which implies that it can not be used to quantify the secondary losses. Lastly, an effort to improve the method used for generating blade profiles is made, and the updated method is used to redesign rotor 2 to reduce losses
