 Removing Prepositions in Defining Thought

Having turned my back on propositions, I thought, what am I going to do about this? The area where it really comes up is when you start looking at the contents of consciousness, which is my number one topic. I like to quote Maynard Keynes on this. He was once asked, “Do you think in words or pictures?” to which he responded, “I think in thoughts.” It was a wonderful answer, but also wonderfully uninformative. What the hell’s a thought then? How does it carry information? Is it like ...

 Roman Arithmetic

...basic Roman arithmetic is largely rather simple, even for those of us spoiled by Arabic notation. Addition is no sweat, because complex Roman numbers already use what math pros call additive notation, with numerals set beside one another to create a larger number. VI is just V plus I, after all. To add large numbers, simply pile all the letters together, arrange them in descending order, and there’s your sum. CLXVI plus CLXVI? CCLLXXVVII, or CCCXXXII. And one of the advantages of the Rom...

 Outsourcing our Thinking to Algorithms and Those Who Engi...

...even as an algorithm mindlessly implements its procedures – and even as it learns to see new patterns in the data – it reflects the minds of its creators, the motives of its trainers. Amazon and Netflix use algorithms to make recommendations about books and films. (One-third of purchases on Amazon come from these recommendations.) These algorithms seek to understand our tastes, and the tastes of like-minded consumers of culture. Yet the algorithms make fundamentally different recommend...

 Gamification Pattern Building Mechanic

Ms. Forsythe divides her class into four teams (Egypt, Mesopotamia, Greece, and Rome). Each team, over the course of the unit, learns about all four artistic cultures but becomes an expert in one. For a 20- to 30-minute exercise in discerning and judging the difference among these artistic cultures, Ms. Forsythe displays a piece of sculpture from each of the four cultures onto a large piece of heavy paper or cardboard and then cuts that image into smaller tiles and tosses all of the pieces to...

 Effects of Good Teachers on Student Outcomes

These findings would suggest that the difference in achievement gains between having a 25th percentile teacher (a not so effective teacher) and a 75th percentile teacher (an effective teacher) is over one-third of a standard deviation (0.35) in reading and almost half a standard deviation (0.48) in mathematics. Similarly, the difference in achievement gains between having a 50th percentile teacher (an average teacher) and a 90th percentile teacher (a very effective teacher) is about one-third...

 Theoretical Uncertainty has No Meaning

If one looks at the history of knowledge, it is plain that at the beginning men tried to know because they had to do so in order to live. In the absence of that organic guidance given by their structure to other animals, man had to find out what he was about, and he could find out only by studying the environment which constituted the means, obstacles and results of his behavior. The desire for intellectual or cognitive understanding had no meaning except as a means of obtaining greater secur...

 Essay Writing is About Figuring Things Out

To understand what a real essay is, we have to reach back into history again, though this time not so far. To Michel de Montaigne, who in 1580 published a book of what he called "essais." He was doing something quite different from what lawyers do, and the difference is embodied in the name. Essayer is the French verb meaning "to try" and an essai is an attempt. An essay is something you write to try to figure something out. Figure out what? You don't know yet. And so you can't begin with a ...

 You Need More than Passion to Change the World

You have to go through life with more than just passion for change; you need a strategy. I'll repeat that. I want you to have passion, but you have to have a strategy. Not just awareness, but action. Not just hashtags, but votes. [...] But to bring about structural change, lasting change, awareness is not enough. It requires changes in law, changes in custom. If you care about mass incarceration, let me ask you: How are you pressuring members of Congress to pass the criminal justice ...

 Ways to Tackle a Problem

If a problem seems familiar, try reasoning by Analogy.  If you solved a similar one in the past, and can adapt to thedifferences, you may be able to re-use that solution.  If the problem still seems too hard, divide it into several parts.  Every difference you recognize may suggest a separate subproblem to solve. If it seems unfamiliar, change how you’re describing it. Find a different description that highlights more relevant information. If you get too many ideas, then focus on ...

 Standing Desks Improve Student Engagement

The research looked at the results of an experiment in which 282 participants in grades 2-4 were observed in the fall and spring during one school year. Student engagement was monitored by actions such as answering a question, raising a hand, or participating in discussion, while off-task behaviors included talking out of turn. Engagement of the "treatment" classrooms was compared with the engagement of "control" classrooms. The researchers noted that both groups showed "general increases in...
