As our Fall 2014 Fellowship ramps up (250+ applicants!), we wanted to do a blog post illustrating how exactly we can use data to understand public services better. Tip 1: before analyzing the data we should understand when the events happened, and if the system that records the data, also known as the data generating mechanism, is biased to a particular period of time. Our natural intuition may want to ask does criminal activity vary according to the day of the week? First we will just check how many Mondays, Tuesdays, etc have data recorded in the dataset: Great! There are lots of different types of crimes here, some that are very similar to each other and some that are very different. Tip 2: We can simplify large categorical variables by binning them into a few major categories We solve this problem by defining a simpler category for crime type which can be "minor", "serious" or "violent".
What’s the “problem” with MOOCs? « EdTechDev In case the quotes didn’t clue you in, this post doesn’t argue against massive open online courses (MOOCs) such as the ones offered by Udacity, Coursera, and edX. I think they are very worthy ventures and will serve to progress our system of higher education. I do however agree with some criticisms of these courses, and that there is room for much more progress. I propose an alternative model for such massive open online learning experiences, or MOOLEs, that focuses on solving “problems,” but first, here’s a sampling of some of the criticisms of MOOCs. Criticisms of MOOCs Khan Academy The organization is unclear and it lacks sufficient learner support.The videos aren’t informed by research and theory on how people learn, and this may diminish the effectiveness of his videos. Are MOOCs a Horseless Carriage? In the book How People Learn (which can be read free online), John Bransford shared the story of Fish is Fish. MOOC or MMORPG?

All of the advice in this class is geared towards people starting a business where the goal is and eventually building a very large company. Ideas, Products, Teams and Execution Part I So the four areas: You need a great idea, a great product, a great team, and great execution. You may still fail. One of the exciting things about startups is that they are a surprisingly even playing field. Before we jump in on the how, I want to talk about why you should start a startup. The specific passion should come first, and the startup second. Thank you.
8 Books For a Higher Existence Books are magical inventions. By carrying meaning, they gives us glimpses of experience and knowledge from a different world. Phonetic language, being cut-off from time and place, the Now, helps both to encapsulate the ego more, but also to offer guidance to make it poriferous, letting Eros free. Without books we would lose this guidance. If you’re done reading this list and want to level up more – check out part two! Thus Spoke Zarathustra – Friedrich Nietzsche Thus Spoke Zarathustra is Nietzsche’s most prophetic book in which he offers his teachings through the words of Zarathustra, based on the Persian prophet Zoroaster, who, after spending ten years on a mountain in meditation only accompanied by his Eagle and Serpent, comes down to offer his wisdom to the world. Becoming Animal – David Abram Abram’s first book The Spell of the Sensuous convincingly argued that being human is inseparably interconnected with everything that is not human.

A Year in Reading 2012 By C. Max Magee posted at 6:00 am on December 3, 2012 20 The end of another year is here (so soon? Ah, I’m getting old), and with it a flood of valedictory lists and wrap ups, accountings and scorecards. Each year, as these lists spill out across the landscape, the onslaught becomes difficult to parse and begins to feel suspiciously (to us, anyway) like a marketing boondoggle to support the promotional-book-cover-sticker-and-blurb industry. There are so many “best of the year” lists that everything is the best (and sometimes also the worst). So, how can we have some year-end fun while still extracting something meaningful from the effort? We readers tend to be a thoughtful bunch, noting down the titles we have read or lining them up one by one on a shelf. And so in preparing our annual Year in Reading series, we’ve asked our esteemed guests to take us on a tour of these pinnacles and to give an accounting of these treks.
