RSA Animate - Changing Education Paradigms. The Creativity Crisis: Hardback: Roberta Ness. Strong critique of the academic system from a leading university dean and expert in science and innovationExplores the question of why science finds itself at a crossroad between extraordinary possibility and frustrating inactionA cogent and urgent argument for a rebalancing of priorities in funding agencies, universities, and industriesDescribes opportunities for reinvigorating scientific innovation, such as engaging broad-based resources, capturing the richness of available talent for the purpose of serving society's interests, and gaining flexibility through failing as quickly and painlessly as possibleEvery day we hear about some fascinating new discovery.
Yet anemic progress toward addressing the greatest risks to humankind — clean energy, emerging infections, and cancer — warns us that science may not be meeting its potential. Indeed, there is evidence that advances are slowing. Science is costly and can hurt people; thus it must be pursued with caution. CompTIA :: Pearson VUE.

The behaviorist theory popularized by B.F. Skinner still drives much of the practice of science education. For more than a quarter century, schools and teachers have been creating behavioral goals and objectives. Curricula have been tightly sequenced according to a belief that the best way to learn is to master small bits of knowledge and then integrate them into major concepts. Assessment practices have tended to focus on measurement of knowledge and skills, with little emphasis on performance and understanding. Since the late 1980s, however, researchers have been building an understanding of learning that grows out of cognitive and developmental psychology. The key notion in this new "constructivist theory" is that people learn best by actively constructing their own understanding.
The fundamental beliefs underlying this new paradigm for learning have been generally summarized as follows: All knowledge is constructed through a process of reflective abstraction.

Original version written in 1994 and published in the Sun Observer Introduction to Sed How to use sed, a special editor for modifying files automatically. There are a few programs that are the real workhorse in the UNIX toolbox. One way to think of this is that the old, "classic" version was the basis of GNU, FreeBSD and Solaris verisons of sed. The Awful Truth about sed Sed is the ultimate stream editor.
Anyhow, sed is a marvelous utility. . SedChart.pdf. Learn C# for Beginners – Microsoft Virtual Academy. Processors That Work Like Brains Will Accelerate Artificial Intelligence. Picture a person reading these words on a laptop in a coffee shop. The machine made of metal, plastic, and silicon consumes about 50 watts of power as it translates bits of information—a long string of 1s and 0s—into a pattern of dots on a screen. Meanwhile, inside that person’s skull, a gooey clump of proteins, salt, and water uses a fraction of that power not only to recognize those patterns as letters, words, and sentences but to recognize the song playing on the radio.
Computers are incredibly inefficient at lots of tasks that are easy for even the simplest brains, such as recognizing images and navigating in unfamiliar spaces. Machines found in research labs or vast data centers can perform such tasks, but they are huge and energy-hungry, and they need specialized programming. Google recently made headlines with software that can reliably recognize cats and human faces in video clips, but this achievement required no fewer than 16,000 powerful processors. Neurons Inside.
