 Negative Attention is Better Than No Attention at All

To give and receive attention is a fundamental human need. In the 13th century, King Frederick II of Sicily wanted to find out what language children would naturally grow up to speak if they were never spoken to. He took babies from their mothers at birth and placed them in the care of nurses who were strictly forbidden to either speak to or touch them. The babies, as it turned out, didn’t grow up to speak any language, as they all died of attention deprivation within a fortnight of the sta...

 Border Crossings into Science Culture

Learning to communicate in and with a culture of science is a much broader undertaking than mastering a body of discrete conceptual or procedural knowledge. One observer, for example, describes the process of science education as one in which learners must engage in "border crossings" from their own everyday world culture into the subculture of science.^ The subculture of science is in part distinct from other cultural activities and in part a reflection of the cultural backgrounds of scienti...

 Blockchains

Ownership on the Bitcoin blockchain is determined by a pair of cryptographic keys. The first, called the public key, resides in the blockchain for anyone to see. The second is called the private key, and its owner keeps it safe from view. The two keys have a special mathematical relationship that makes them useful for signing digital messages. Here’s how that happens: Helmut takes a message, combines it with his private key, does some calculations, and ends up with a long number. Anyone who...

 Children's Art Has Its Own Logic

Even simple scribbles are meaningful. While it was once thought that kids only scribbled to experience the physical sensation of moving their arm along the page, “now it’s been shown that when children are scribbling … they’re representing through action, not through pictures,” said Boston College’s Winner. “For example, a child might draw a truck by making a line fast across the page and going ‘zoom, zoom,’ and so it doesn’t look like a truck when the child is done, but i...

This reminds me of Sagan's pumpkin-carving, where he made random cuts and took out chunks to make it scarier with more "bloody guts."

 Choral Reading

Choral reading gives students the experience of reading aloud without the stress of reading alone. Based upon the previously described research demonstrating that repeated stimulation of neuronal networks increases their efficiency, it makes sense that the experience of reading aloud together reinforces patterns. When we start the choral reading, I ask students to whisper the words as I read aloud. Th is process continues until students become more confident. As the reading progresses and I ...

 Whole Earth Catalog Purpose

We are as gods and might as well get good at it. So far, remotely done power and glory—as via government, big business, formal education, church—has succeeded to the point where gross defects obscure actual gains. In response to this dilemma and to these gains a realm of intimate, personal power is developing—power of the individual to conduct his own education, find his own inspiration, shape his own environment, and share his adventure with whoever is interested. Tools that aid this p...

 Mathematics is Hard Work, Not Genius

What I fight against most in some sense, [when talking to the public,] is the kind of message, for example as put out by the film Good Will Hunting, that there is something you're born with and either you have it or you don't. That's really not the experience of mathematicians. We all find it difficult, it's not that we're any different from someone who struggles with maths problems in third grade. It's really the same process. We're just prepared to handle that struggle on a much larger scal...

 Natural Selection Resembles Bayesian Inference

The analogy is mathematically precise, and fascinating. In rough terms, it says that the process of natural selection resembles the process of Bayesian inference. A population of organisms can be thought of as having various 'hypotheses' about how to survive—each hypothesis corresponding to a different allele. (Roughly, an allele is one of several alternative versions of a gene.) In each successive generation, the process of natural selection modifies the proportion of organisms having each...

 Perspectives of History

The trouble I think is that historians dont actually agree on much about those processes. The post-marxist school of thought sees history as a process of struggles over resources between interest groups. Foucaultians see history as a process born of the "techniques" of power the elites wield over the non elites, Traditional liberalism saw history as a Hegelian (Not to be confused with marxisms very different view) process of gradual movements towards technological, social and cultural perfec...

 How to Teach Vocabulary

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 process. Skipping this step can be disastrous as students may have a misconception that will be placed in long-term memory through incorrect rehearsals (Sprenger, 2005). Ask ...
