Pupil groupings within classrooms: social pedagogy within cultural contexts
There have been many studies of teaching and learning in classrooms, for example, involving teaching approaches and styles, learning or broad classroom level structures (e.g. age of pupils, ability, curriculum). These studies offer insights into teaching effectiveness, patterns of learning and broad explanations of classroom effects, yet they add little insight into the complex ecology that characterises children’s development in school contexts.

5 Summary and conclusion

In this unit we have considered questions surrounding the future of school geography. This may at first seem an odd question, but it is salutary to remember that the advocates of geography had to work very hard to make the case for the subject's place in the English National Curriculum.

As the unit sought to show, even if we can agree that geography has an important role to play in schools, opinions vary as to the purpose of the subject:

4.510 Digital Design Fabrication (MIT)
This course will guide graduate students through the process of using rapid prototyping and CAD/CAM devices in a studio environment. The class has a theoretical focus on machine use within the process of design. Each student is expected to have completed one graduate level of design computing with a full understanding of solid modeling in CAD. Students are also expected to have completed at least one graduate design studio.

7.349 From Molecules to Behavior: Synaptic Neurophysiology (MIT)
Like transistors in a computer, synapses perform complex computations and connect the brain's non-linear processing elements (neurons) into a functional circuit. Understanding the role of synapses in neuronal computation is essential to understanding how the brain works. In this course students will be introduced to cutting-edge research in the field of synaptic neurophysiology. The course will cover such topics as synapse formation, synaptic function, synaptic plasticity, the roles of synapses

2 The role of the governing body

When performance review was first introduced, many governing bodies felt unable to undertake the role with confidence. They felt they were being asked to judge teachers and, particularly, headteachers, and were not comfortable with this.

Although the governing body is responsible for the performance management process in the school, it is not the role of the governing body to monitor the work of individual teachers. This is the task of the headteacher, or other appropriate

2.3.1 Cylinder

The simplest example of a paper-and-glue construction is to make a rectangle into a cylinder by gluing together two opposite edges. We take a closed rectangle ABB' A' in the plane and identify the opposite edges AB and A'B', as shown in Figure 27. This means that:

2.2 Breathing air

A swimming elephant can breathe by holding the end of its trunk out of the water, but if it tried to find its food under the surface, like the desman, it would have to hold its breath. Neither the mammalian lung nor the skin can extract enough oxygen from water to sustain life, so aquatic mammals must come to the surface at intervals to breathe; and all of them - pinnipeds, sirenians and cetaceans - drown if they are prevented from doing so for prolonged periods.

Lungs form 7% of the bo

Governments Turn to the UN to Avoid Paying Their Debts

The Mises Institute recently spoke with Nicolás Cachanosky, an Argentina-born economist, now at the Metropolitan State University of Denver, who is familiar with sovereign debt issues. We asked him about a recent UN resolution that seeks to make it easier for governments to default on their debts.

3.5 Expansion and contraction of the piece: wilet

It should already be clear that, in order for this music to work, musicians need to listen out carefully for what their colleagues are doing. For instance, since the saron I has at least three possible patterns to play (lancaran, caruk and ciaseman), the saron II player must keep listening in case his colleague changes from one to another. The same ‘interlocking’ principle applies to certain other instalments too. In order to show just how important group interaction is in this music howe

3.5.3 Protozoa

Protozoa are microscopic single cell animals. They utilise solid substances and bacteria as a food source. They can only function aerobically, and in a stream which contains little organic degradable matter they can become a predominant microbial type. They play an important part in sewage treatment where they remove free-swimming bacteria and help to produce a clear effluent.

In an aquatic environment, there are three main types of protozoa:

10.5 Desire to help others

This is a less common motivation but it shows not everyone is driven by money.

In 1991 the inventor Trevor Baylis saw a BBC documentary about the spread of HIV/AIDS in Africa. What was needed was a way of broadcasting the safe-sex message to people in areas without electricity and where batteries for a radio could cost a month's wages. Solar power wouldn't necessarily help as most people who could get to a radio listened in the evening after work. While absorbing this information he ima
