Cooperative and Collaborative Learning: Explanation
What are cooperative and collaborative learning? Collaborative learning is a method of teaching and learning in which students team together to explore a significant question or create a meaningful project. A group of students discussing a lecture or students from different schools working together over the Internet on a shared assignment are both examples of collaborative learning. Cooperative learning, which will be the primary focus of this workshop, is a specific kind of collaborative learning. In cooperative learning, students work together in small groups on a structured activity. In small groups, students can share strengths and also develop their weaker skills. In order to create an environment in which cooperative learning can take place, three things are necessary. Also, in cooperative learning small groups provide a place where: For more detailed descriptions of cooperative and collaborative learning, check out the books, articles, and Web sites listed on our Resources page.

Human Nervous System - Diagram - How It Works
The nervous system, essentially the body’s electrical wiring, is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. Neurons signal to other cells through fibers called axons. Chemicals called neurotransmitters are released at gaps called synapses. These communications take only a fraction of a millisecond. Sensory neurons respond to stimuli such as light and sound. Neurons are supported and fed by glial cells. Vertebrates, animals with backbones and spinal columns, have central and peripheral nervous systems. The Central Nervous System is the integration and command center of the body. The Peripheral Nervous System consists of sensory neurons, ganglia (clusters of neurons) and nerves that connect the central nervous system to arms, hands, legs and feet. The Cranial Nervous System nerves connect the brain to the eyes, mouth, ears and other parts of the head. Related: Nervous System: Facts, Function & Diseases

Fragment of rat brain simulated in supercomputer
A simulated brain slice from the Blue Brain Project: neurons are coloured according to their levels of electrical activity. A controversial European neuroscience project that aims to simulate the human brain in a supercomputer has published its first major result: a digital imitation of circuitry in a sandgrain-sized chunk of rat brain. The work models some 31,000 virtual brain cells connected by roughly 37 million synapses. The goal of the Blue Brain Project, which launched in 2005 and is led by neurobiologist Henry Markram of the Swiss Federal Institute of Technology in Lausanne (EPFL), is to build a biologically-detailed computer simulation of the brain based on experimental data about neurons' 3D shapes, their electrical properties, and the ion channels and other proteins that different cell types typically produce (see ‘Brain in a box’). Such a simulation would provide deep insights into the way the brain works, says Markram. But Markram is undeterred.

Reverse Engineering The Brain
This is part of IEEE Spectrum's SPECIAL REPORT: THE SINGULARITY PHOTO: Timothy Archibald What do fruit-fly brains have in common with microchips? That's not the setup for a bad joke; it's David Adler's life. Located in the green, rolling hills of Ashburn, in northern Virginia, the campus, known as Janelia Farm, has been described as a kind of Bell Labs for neuro-biology. ”In a hundred years I'd like to know how human consciousness works,” says Janelia director Gerry Rubin. ”The 10â¿¿ or 20-year goal is to understand the fruit- fly brain.” To that end, Rubin has stocked the Janelia campus with a collection of neuro-scientists, biologists, physicists, engineers, and computer scientists. Like an IC, the fruit-fly brain is subjected to logic and optical testing to derive its circuit diagram. A standard scanning electron microscope (SEM) images at about 10 million pixels per second. Slice, image, slice, image. Compared with an IC , even a tiny fruit-fly brain is a mess.
