Big data and social networks for students preparing for college

The common denominator between both these uses of technology is the nonprofit organization College Summit.  You can check it out at Charity Navigator

In Bridging the Gap to the Goal With Educational Data
I focus on the use of data:


Armed with that information, educators can make informed decisions about what modifications are needed to better prepare the next batch of students for their college careers.As Camille Jacobs, Assistant Principal, Pathways College Preparatory High School, Queens, NY, noted in the College Summit whitepaper, "With postsecondary data, we have the ability to work backwards, improving or revising our practices to provide targeted instruction and services, addressing the varying needs of each of our students."

In College Apps for College Apps I look at the social media apps designed to help students to and through college. College Summit was one of the key organizations behind  The College Knowledge Challenge, which awarded prize money to the best apps for student use.

Getting libraries out of the horse-and-buggy days

In 1967, Dr. Vannevar Bush, who envisioned a computer capable of massive data retrieval in device he called a memex  published Science Is Not Enough, which included a chapter entitled "Memex Revisited," which considers the question of data compression and retrieval.  You can read the entire chapter here: http://www.bekkahwalker.net/comt111a/reading_pdf/memex-revisited.pdf

On p. 88, he brings a critical observation about priorities: 

The great digital machines of today have their exciting proliferation because they could vitally aid business, because they could increase profits. The libraries still operate by horse-and-buggy methods, for there is no profit in libraries. Governments spend billions on space since it has glamour and hence public appeal. There is no glamour about libraries, and the pubic do not understand that the welfare of their children depends far more upon effective libraries than it does on the collection of a bucket of talcum powder from the moon. So it will not be done soon. But eventually it will.

Now, 46 years, later, the public is understanding the importance of libraries, and the power of the internet to gather all the world's digitized information at put them at one's fingertips.On April 18 and 19, the Digital Public Library of America (DPLA) will celebrate its launch at the Boston Public Library. In keeping with the ideals underlying the project, there is no charge to attend, though the registration forms indicate the event has filled up.


The dream of the DPLA was to harness the power of the Internet to break through the silos that isolate vast quantities of data collection at various universities, museums, and libraries. It began to take shape in late 2010 when representatives of various institutions met at the Radcliffe Institute in Cambridge, Mass., and resolved to take the necessary steps to bring together that data through cooperative content sharing. In bridging the public-private divide, DPLA has had to overcome the challenge of managing metadata variations and staying on the right side of copyright law.

Misplacing a valued client

Citibank was nice enough FedEx me an illustration of a misplaced modifier. The letter begins: "As a valued client, we recently mailed a letter to you regarding an incredible opportunity to receive relief on your mortgage payment through Home Affordable Refinance Program. " As far as grammar is concerned, we only need to focus on the first five words. The way the sentence is set up the first four words are a description that should be followed by what they modify, but instead, they are followed by the pronoun "we," that is the entity that makes up Citibank, which is not its own valued client. 

To make the sentence work grammatically, Citibank could have opened with something like thins, "Because we value you as a client, we want to let you know about an incredible opportunity," or something along those lines.

Your guide, not you're guide

In honor of National Grammar Day, which is celebrated on March 4th,  here's a quick guide to pronouns and apostrophes. While people tend to get confused and add in unnecessary apostrophes at times, when it comes to pronouns, all you have to think about is this: contractions do have apostrophes, whereas possessive forms do not.

The apostrophes in contractions take the place of the letters that get knocked off when two words are combined into one, thus "I am" becomes "I'm," and "it is" becomes "it's." In contrast, possessive pronouns inherently convey possession without any apostrophe. Just like we write "his" and not "hi's" or "his'" for belonging to him,  we write "its" (with no apostrophe) for belonging to it.

Here's the list of pronouns in contraction and possessive form:
                                         Contraction                          Possessive Pronoun
                                             I'm                                             my
                                            you're                                         your
                                            he's                                             his
                                            she's                                            her
                                            it's                                               its
                                            we're                                           our
                                           they're                                          their

From the list above, people tend to confuse the ones that sound alike: it's/its and they're/their. Interesting enough, I don't really see "you're" mistaken for "your," even though both words sound exactly the same, The thing to remember is that just as you would not write "you're" or the nonexistent "you'r"  for the word that mean belonging to you, you cannot write "it's" for the word that means belonging to it, no matter how common the error.

The same holds true for "their," which is not only confused with the contraction "they're" but even with the third homonym for the grouping, "there."
