CREW stands for Continuous Review Evaluation and Weeding, and the manual uses “crew” as a transitive verb, so one can talk about a library’s “crewing” its collection. It means weeding but doesn’t sound so harsh. At the heart of the CREW method is a formula consisting of three factors—the number of years since the last…
What concerns me is how our information networks have enabled us to become hyper-connected to geographically distant communities, while at the same time disconnected from our local ones. Virtual and long-distance relationships can enrich our lives in myriad ways, but I fear that our reliance on them has the potential…
One activity is segmenting sounds and then blending them together using both real words and nonsense words. This activity gives students practice manipulating phenomes and is consistent with the research supporting stimulation of both posterior processing systems (McCandliss, Cohen, & Dehaene, 2003). Another activity…
A gamespace is a uniquely coded and constructed place where players are expected to act before being any good at what they’re doing; they’re spaces inherently founded on the notion of risk taking. The process of building a classroom that functions as a gamespace should start with the teacher being committed to…
Acquire as little software as you can get by with, and stick with it. That's hardware critic Richard Dalton's advice. It's easy to get so caught up in the constant onrush of improvements and "next generations" in the software market that you wind up forever getting ready to work instead of working. You can buy last…
Step 1: Empathy = Really get to know your user Use human-centered design process, which puts the user squarely at the center of the process. When designing, you start with identifying who you want to design for (your user) and really get to know them. 3 ways to get to know our user: Observation (what we observe them…
The Deletionist is a concise system for automatically producing an erasure poem from any Web page. It systematically removes text to uncover poems, discovering a network of poems called “the Worl” within the World Wide Web. [...] The Deletionist takes the form of a JavaScript bookmarklet that automatically creates…
At first sight, things seem quite similar in City Number Two. Again, there are ubiquitous cameras, perched on every vantage point. Only here we soon find a crucial difference. The devices do not report to the secret police. Rather, each and every citizen of this metropolis can lift his or her wristwatch/TV and call up…
A mantra among hackers is “Less Yack, More Hack.” The hacker is a bricoleur, involved in “making do,” and, in doing so, recovering a non-alienated self. Yet being a “hacker” is more than mere individual inventiveness. It involves a larger set of ideals. A hacker should always practice freedom of expression, respect…
Also central to the Hacker Ethic is playfulness. At a 2006 O’Reilly Emerging Technology Conference, Matt Webb and Ben Cerveny wrote, “Hacking is a playful act. In a primal sense, play is the investigation and experimentation with borders and combinations” (O’Reilly Emerging Technology Conference, website). Despite…
The first study to assess directly the risk of cancer after CT scans in childhood found a clear dose-response relationship for both leukemia and brain tumors: risk increased with increasing cumulative radiation dose. For a cumulative dose of between 50 and 60 milligray or mGy (mGy is a unit of estimated absorbed dose…
An understanding of what the Internet is. "I found it on the Internet" is not an accurate statement. You found it on a computer connected to the World Wide Web. Ways to formulate queries. Typing "childhood obesity" into a search engine is not the best way to discover what health problems are associated with being…
In 1986, John Holloszy of Washington University immersed his lab rats in shallow, cool water for four hours each day. They burned so many extra calories that they ate half again as much as control rats, but weighed less. The cold rats lived 10% longer, on average. Holloszy framed his report on this experiment not as a…
Working with the Choices Program at Brown University, Zupin and a team of social studies teachers in Indiana found that "fishbowls" are a particularly effective strategy for keeping the peace during a controversial political discussion. A group of five to seven students sit in an inner circle (the fishbowl)…
Neocortical neurons have thousands of excitatory synapses. It is a mystery how neurons integrate the input from so many synapses and what kind of large-scale network behavior this enables. It has been previously proposed that non-linear properties of dendrites enable neurons to recognize multiple patterns. In this…
IA, or Intelligence Augmentation, is all about empowering humans with tools that make them more capable and more intelligent, while traditional AI has been about removing humans fully from the loop. The traditional torch bearer for IA is Douglas Engelbart, who laid the seeds for much of the Personal Computer…
Begin with a story or explanation of the term. Modeling how you use the word in your life or in conversation may be helpful to students. Have students put information into their own words. This process, which I call “recoding,” is necessary to make sure students understand the word. This is a vital step in the memory…
Onomatopoeia and sound symbolism are the seeds of a more pervasive phenomenon in language called phonesthesia, in which families of words share a teeny snatch of sound and a teeny shred of meaning. Many words with the sound sn-, for example, have something to do with the nose, presumably because you can almost feel…
Haldane did not foresee the computer, the most potent agent of social change during the last fifty years. He expected his Daedalus, destroyer of gods and of men, to be a biologist. Instead, the Daedalus of this century turned out to be John von Neumann, the mathematician who consciously pushed mankind into the era of…
“In One Dimensions, did not a moving Point produce a Line with two terminal points? In two Dimensions, did not a moving Line produce a Square wit four terminal points? In Three Dimensions, did not a moving Square produce - did not the eyes of mine behold it - that blessed being, a Cube, with eight terminal points? And…
