Lessons in Well Drilling Spill into the Classroom A project to bring clean water to residents of Namawanga, Kenya, serves as an example in lesson plans for middle-school students. Update Nov. 12, 2012: Curricula videos now on YouTube, see belowSince 2006, student engineers from the University of Massachusetts Amherst have teamed with residents of Namawanga, Kenya, to clean the town's drinking water – and teach U.S. students in more than 100 middle and high schools math, science, and social studies. Pastures flank the town's streams and tests detected e.coli in the water. To solve the problem, the residents and students in Engineers Without Borders at UMass are drilling a well and building spring boxes around the water source to protect it from contamination. At the same time, the UMass project is meshed with a multi-disciplinary curriculum for middle and high schools. The lessons spin off from an EWB video documentary about clean water for Kenyans. Virtual engineering Issues in water treatment is one of three curricula.
The Paradigm Shift of Systems Theory I. The Perspective of Systems Theory and its Relationship to the Traditional Mainstream Sciences, and its Approach to Mental Illness “Systems theory” is the name given to both a broad perspective and a large body of knowledge which has formed through the original efforts of many men and women in the last century, all of whom were working under the impulses of an important epistemological paradigm shift. That shift- the implications of which are too numerous and transformative to state or explain adequately in one place- was from the causal/linear and reductionist perspective that had largely dominated scientific thinking in their time, to an interactional perspective that explored reality in important new ways. From the perspective of the traditional sciences, the paradigm shift of systems theory was and is both radical and subversive. A Radical Shift Running for Cover To these pained souls, responses can be given. The Myth of Mental Illness But where is the problem? II.
Math Training Initiative Innovative Math Training Initiative Ground breaking Math initiative educating underprivileged children in slum and village communities via The Khan Academy teaching modules! Research shows that math learning is a vital component in children’s long-term educational development and ability to get a self-sustaining job after school. A proper math education in India enables a child to be streamlined into a normative high school and ultimately into the mainstream workforce. Unfortunately, access to the good math training is rare in India and teaching math in the slums and remote villages is difficult for many logistic reasons. The Khan Academy (www.khanacademy.org), an innovative e-learning solution sponsored by the Bill and Melinda Gates Foundation and the Google Company, provides accessible math modules on the internet in order to enable an child anywhere to obtain a free world-class education. The modules will have an even broader impact.
Make it Obsolete « Essays « Pete Michaud “You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete.” - Buckminster Fuller Fuller was, among many other interests, a systems theorist. When he said you have to make parts of a system obsolete to change anything he was talking about social change, and perhaps market changes. You can’t just kill the Big Four record companies by beating them at their own, rigged game. But this insight doesn’t only apply to society or markets. If you want change, don’t fight yourself. The parts of you that procrastinate and overeat are part of the system because they serve a useful function. Once you do that the old part will fall by the wayside effortlessly. If procrastination is a defense mechanism against failure, and overeating is a surrogate for self-esteem, then embracing failure and finding a real reason to love yourself will make those symptoms evaporate.
The Sow It Forward Garden Grants Program Our application process for 2014 grants is now closed but we are accepting applications throughout 2014 for our 2015 grant cycle.

The grant is for nonprofit causes or organizations (schools, 501c3s, food banks, community gardens, colleges, libraries, prisons, senior programs, etc.) interested in starting or expanding food garden projects that are of general benefit to their community. Past grantees include school gardens, community gardens, food bank gardens, library gardens, senior gardens, prison gardens and homeless shelter gardens among others. For our 2014 round of giving, we offered 100 full grants and roughly 60 partial grants. The partial grant had a value of $325 and consisted of a $300 cash grant and $25 one-year subscription to our online garden planner.
Laplace transform History The Laplace transform is named after mathematician and astronomer Pierre-Simon Laplace, who used a similar transform (now called z transform) in his work on probability theory. The current widespread use of the transform came about soon after World War II although it had been used in the 19th century by Abel, Lerch, Heaviside, and Bromwich. From 1744, Leonhard Euler investigated integrals of the form as solutions of differential equations but did not pursue the matter very far. Joseph Louis Lagrange was an admirer of Euler and, in his work on integrating probability density functions, investigated expressions of the form which some modern historians have interpreted within modern Laplace transform theory.[clarification needed] akin to a Mellin transform, to transform the whole of a difference equation, in order to look for solutions of the transformed equation. Formal definition The parameter s is the complex number frequency: with real numbers and ω. instead of F.
Indian schools adopt tablets. Will they improve education? Richard Mahapatra, a 42-year-old journalist, recently attended a parent-teacher meeting at his daughter’s private school in Delhi. During the meeting, he said, teachers encouraged him to buy a tablet. The school was selling several tablets made by HCL, a leading Indian technology company, for about 6,000 rupees, or $120. Some parents, Mahapatra said, bought the tablets. But the journalist found the whole situation uncomfortable: First, he didn’t like the idea of schools promoting a private company’s tablet, and second, he wasn’t sure how it would benefit his daughter. “For a father like me, it’s not a cultural change but almost like a genetic jump,” he said, recalling that he began his education with chalk and slate at a small tribal school in the state of Orissa on the eastern coast of India. Over the last 15 years, a growing number of Indian schools have been upgrading their technology to include state-of the-art computers accessible to all students. Prasanto K.
State-space representation In control engineering, a state-space representation is a mathematical model of a physical system as a set of input, output and state variables related by first-order differential equations. "State space" refers to the space whose axes are the state variables. The state of the system can be represented as a vector within that space. To abstract from the number of inputs, outputs and states, these variables are expressed as vectors. Additionally, if the dynamical system is linear, time-invariant, and finite-dimensional, then the differential and algebraic equations may be written in matrix form. The state-space representation (also known as the "time-domain approach") provides a convenient and compact way to model and analyze systems with multiple inputs and outputs. With inputs and outputs, we would otherwise have to write down Laplace transforms to encode all the information about a system. State variables Linear systems inputs, outputs and where: is the "input matrix", ). .
Innovation in Education Introduction Education is the crucible in which Innovations are forged. Promoting creativity and incentivizing innovations through our educational institutions is a first step towards broadening and deepening the impact of innovations in our society and economy. In large scale education systems such as ours, catering to a vast population with relatively limited resources, this is a major challenge. (a) Creation of a separate scholarship stream of National Innovation Scholarships analogous to the National Talent Search Scheme. (b) Setting up an Innovation Centre in each DIET (District Institute of Education and Training) to enhance teacher training and enable them to become facilitators of creativity and innovative thinking. (c) Mapping of Local History, Ecology and Cultural Heritage by each High School in the country to create critical thinking on their local environment by students. (f) Setting up twenty Design Innovation Centres co-located in institutes of national importance.
Feedback "...'feedback' exists between two parts when each affects the other."(p53, §4/11) A feedback loop where all outputs of a process are available as causal inputs to that process "Simple causal reasoning about a feedback system is difficult because the first system influences the second and second system influences the first, leading to a circular argument. In this context, the term "feedback" has also been used as an abbreviation for: Feedback signal – the conveyance of information fed back from an output, or measurement, to an input, or effector, that affects the system.Feedback loop – the closed path made up of the system itself and the path that transmits the feedback about the system from its origin (for example, a sensor) to its destination (for example, an actuator).Negative feedback – the case where the fed-back information acts to control or regulate a system by opposing changes in the output or measurement.
