Could Storytelling Be the Secret Sauce to STEM Education? In the short story “The Ones Who Walk Away from Omelas,” author Ursula Le Guin describes a utopian city that has everything people want or need — beauty, religion, happiness — but it’s all possible because one child is kept in the dark, separated from all joy and light. Citizens of the city have to go and see this boy, but some can’t take the guilt and walk away. After reading the story, Lev Fruchter and his class talk about what elements make up utopia and use the conversation as a jumping-off point to talk about equations. They talk about adding good things and multiplying them if they’re really great or, inversely, subtracting things that make people unhappy and dividing the really bad elements. This is all a way of thinking about the math that will eventually run a computer program. Fruchter loves words, but is comfortable enough with math and science that he was called upon to teach them.

Map / Reduce – A visual explanation Map/Reduce is a term commonly thrown about these days, in essence, it is just a way to take a big task and divide it into discrete tasks that can be done in parallel. A common use case for Map/Reduce is in document database, which is why I found myself thinking deeply about this. Let us say that we have a set of documents with the following form: And we want to answer a question over more than a single document.
27 Ways to Learn to Program Online Whether you are looking to switch careers and become a full-time programmer, want to try to build a website or app on the side, or are just looking to round out your skill set, learning to code has certainly been something a lot of people have started to do lately. And while being a programmer might not be for everyone, there is a lot to be said about gaining a better, more educated view of how all those pixels get moved around all those screens. Before we delve into our list of learning resources sites, we wanted to share some advice from Marissa Louie, a self-taught product designer for Ness Computing. A former startup founder, Louie told TNW that the hardest part of being self-taught – whether it’s design, programming, or any other discipline is, “gathering the courage. The most important barrier is just to overcome your fears” (she also said having the ability to follow instructions helps as well). 1.
How to Safely Download & Install Software All of these programs that I recommend are hosted on other sites, which is very typical and is no reason for concern. However, it means I have hand you off to another website that I have no control over and hope everything works out there as you download and install the software. Unfortunately, sometimes even a really, really good piece software is hosted at a site that... well, I wouldn't otherwise want to send someone to.
Should students learn coding? Students, schools disagree, poll finds SAN FRANCISCO — Parents across the U.S. are eager for their children to learn coding and other computer-science skills, but their message hasn't yet hit the in-box of school administrators. That's the finding of a new Gallup study commissioned by Google that spotlights a potentially perilous economic disconnect as tech companies struggle to enlarge their engineering talent pools. In the works for 18 months, the survey, called "Searching for Computer Science: Access and Barriers in U.S.

Programming resources Programming knowledge is not mandatory for LessWrong but computer science and programming is a popular topic among LessWrong members and it is also instrumentally useful to understand how computers work and how to program them. Even if you are not interested to learn to program, you might want to be able to at least interpret the most basic pseudo code as you might come across various snippets of code in discussions and top-level posts outside of the main sequences. Below you will find a list of links to books and other resources. Most categories are sorted by their difficulty in ascending order. Resources that can be understood with little or no knowledge of computer science and programming are marked EASY.
