• The importance of letting students stumble

  By ljd42 on September 13, 2014

  One consequence of being away from blogging for over six months is that I’ve let some interesting posts from other bloggers just lie hanging without commenting on them. So, let’s look at two KQED essays on almost the same topic,… Read More ›

• Back from the void

  By ljd42 on September 12, 2014

  So…it’s been months and months, and I’ve totally gotten out of the habit of blogging. Time to resume! My new goal is five posts per week for the next n weeks (value of n to be discovered).  

• 88 Wharf revisited

  By ljd42 on February 28, 2014

  

  A little over a year ago, I wrote a post in which I speculated about whether 88 Wharf was going out of business. I had liked this Milton restaurant a lot back in 2009–2011, but by 2012 it had gone downhill…. Read More ›

• “Off-track geometry”

  By ljd42 on February 27, 2014

  JD2718 is always worth reading. I used to know his real name, but I’ve lost track of it. No matter; he teaches geometry, studies cryptography, and just turned 50, so we know he’s a good guy. A few months ago… Read More ›

• Voynich

  By ljd42 on February 25, 2014

  “A mysterious document that has bedeviled scholars and top cryptographers for more than a century,” says the Boston Globe. Is it written in code? Is it art? How old is it? Read the article for some tantalizing information — and lack of… Read More ›

• What do teachers do?

  By ljd42 on February 23, 2014

  Must reading: The Teachers, by Sarah Blaine. Click on the link. Go read it before you get any further in this post…. … Finished? Read Blaine’s last paragraph again: The problem with teaching as a profession is that every single… Read More ›

• Why private schools are better than public schools…or are they?

  By ljd42 on February 21, 2014

  Everyone knows that private schools are better than public schools, right? Of course that’s a gross generalization — for instance, no one would claim that a third-rate private school is better than Weston High School — but surely it’s true… Read More ›

• Don’t keep calm.

  A refreshing change:

• The Outer Limits of Reason

  By ljd42 on February 18, 2014

  

  Science and math can tell us everything there is to know about the universe, right? There must be people who believe that. If such people exist, they should definitely run out and read Noson Yanofsky’s new book, The Outer Limits of… Read More ›

• Yes, that's the problem.

• What works in education

  By ljd42 on February 14, 2014

  It’s hard to know where to begin this post. Perhaps I should simply ask you to read “What works in education” by Grant Wiggins — including the comments. Wiggins discusses John Hattie’s extensive statistical studies that compare the effectiveness of… Read More ›

• William in a box

  By ljd42 on February 12, 2014

  

  I guess William wants to be sent by Priority Mail.

• Bring Your Own Technology: A brief progress report

  By ljd42 on February 11, 2014

  

  Six months ago I wrote a post about the “Bring Your Own Technology” initiative at Weston (BYOT). It’s time for an informal progress report (from my own point of view — which of course is objective and completely unbiased). On the… Read More ›

• Come to the Fair!

  By ljd42 on February 9, 2014

  Come visit Weston’s Twelfth Annual Fractal Fair, which is being held on Valentine’s Day this year! That’s Friday, February 14, 10:05-12:15 in the Weston High School Library. The exhibits and presentations by 70 Honors Precalculus students (mostly juniors) will focus on… Read More ›

• Affluenza

  By ljd42 on February 7, 2014

  I’m uncharacteristically speechless. As Dr. Boyce Watkins puts it, “Rich, white kids have ‘affluenza,’ poor, black kids go to prison.” Here’s the story: A wealthy teen who killed four people in a Texas drunk driving accident will not go to… Read More ›

• Jamaica Plain: No comment.

  By ljd42 on February 6, 2014

  

  So I’m in the lobby outside Bella Luna Restaurant in the Brewery Small Business Complex in Jamaica Plain, looking at the bulletin board, and I spot the juxtaposition of these two notices on their community bulletin board. I’ve drawn blue… Read More ›

• Suppose math tells you something that goes against your preconceived beliefs. What do you do?

  By ljd42 on February 4, 2014

  Yale Law School’s Dan Kahan and three other researchers make the case that those more skilled at math are less likely to come to the correct conclusion on controversial matters—even when the numbers to support that conclusion are clear, empirical,… Read More ›

• Cryptology? Cryptography? Crypto?

  By ljd42 on February 2, 2014

  One of my students claimed that I was being inconsistent because I sometimes wrote cryptology, sometimes cryptography, and sometimes just crypto. What’s going on here? I suppose I could quote Walt Whitman on the subject of contradicting myself, or I could quote Emerson on the subject… Read More ›

• Data visualization

  By ljd42 on January 31, 2014

  

  “Chartjunk?” you ask. “What’s that?” The term comes from Edward Tufte, whose work I have admired for thirty years. If you only have a small amount of time to read what he has written, I recommend the beautiful, 200 page classic, The… Read More ›

• And God Said

  By ljd42 on January 29, 2014

  

  Brandeis professor Joel Hoffman’s wonderful linguistic analysis is surprisingly readable and engaging. I recently read his full-length book, And God Said: How Translations Conceal the Bible’s Original Meaning, which is filled with such analysis. Normally I’m not enthusiastic about quoting other readers’ reviews… Read More ›
