Chalk Apocalypse

So, when Hagoromo announced that it was going out of business in 2014, it caused a rupture in the math community.”

I referred to it as a chalk apocalypse,” Conrad said. In a panic, mathematicians across America began stockpiling resources in preparation.”

I calculated how many boxes I would need to last 10 to 15 years and I bought that many boxes,” says Lieblich.Dave Bayer took things even further. “I single-handedly bought the rest of the Amazon supply in the middle of the night,” he said.

I was gifted with an old sliding blackboard in my 2nd year of teaching (and my first year of teaching Physical Science). I loved that board and was sad to leave it later in my career when I went to a new school.

There’s something special about chalk covered hands and the feel of writing on a blackboard to make a point about F=MA or the structure of an atom.

Now I want to go stock up on some Hagoromo and find a good blackboard for my children.

Stanford to cut Stanford Univ. Press

Just wow.

The Stanford press actually brings in about $5 million a year in book sales, a sum that is impressive compared to sales of many scholarly publishers. But it has also depended on support from the university, which in recent years has provided $1.7 million annually.

Provost Persis Drell told the Faculty Senate Thursday that the university was ending that funding. She cited a tight budget ahead, due to a smaller than anticipated payout coming from the endowment. (The endowment is worth more than $26 billion and is the fourth largest in American higher education.)

Stanford publishes about 130 books a year. It is particularly well-known in the fields of Middle Eastern studies, Jewish studies, business, literature and philosophy. The press has also been capable of undertaking long-term scholarly efforts, such as a 20-year project to translate the Zohar, the key work in understanding the Jewish thought of the Kabbalah.

You’re not “addicted” to tech and why it’s dangerous to say you are

As a teacher from 2001-2006 and then from 2008-2012, I had the chance to work with dozens of young people and their parents at a time when so much we knew and thought about education and transmitting information was changing. There was a rapid cultural shift in that decade that was primarily driven by “technology” and the internet.

One theme that remained constant going back to the first time we set up a class blog in 2003 was the notion of “tech addiction”. It remained a constant question and concern of parents and education colleagues (particularly my administrators) over the years.

Since 2012 as a marketing and tech consultant primarily working with religious orgs, nonprofits, and community groups, I’ve encountered the same concerns about tech addiction and young people. From MySpace to Instant Messaging to World of Warcraft to Instagram to Facebook to Fortnite, the boogeyman of evil tech hellbent on ruining our children’s minds and attention and willingness to go outside and play stickball keeps a constant current over time.

However, tech addiction (in the mainstream cultural sense) is just that… a boogeyman. It’s much better to focus on our responsibilities and usage patterns… as adults and parents and community members… rather than blaming Zuckerberg for our lack of accepting personal agency and being responsible people with our choices.

Good piece here that says all this in a much nicer and more approachable way:

Nir says the idea that technology is “hijacking your brain” or that the general population is “addicted” to their phones is rubbish.“Yes, there’s a very small percentage of people that very much are addicted—which is a completely different conversation—but this ‘addiction to technology’ is not the generalized disorder the media and others would have you think it is.”

Defending the Liberal Arts

Long overdue…

The new statement offers a counterargument to the notion that the liberal arts are impractical, and perhaps unnecessary. The disciplines, it argues, increase students’ curiosity, prepare them to be lifelong learners, and offer a foundation for academic freedom. As a result, the associations argue, the benefits of the liberal arts should be available to “all college students and not solely a privileged few.”

The dangers of thinking “They’ll get it because they’re young”

So very true despite the stereotypes (spoken as a former college / high school / middle school teacher turned tech consultant). Parents have a big burden to bear in helping their young and old children make wise decisions about how and why to use the web. Just assuming “they’ll get it because they’re young” is very dangerous.

What is surprising about this data is that while education is a factor in online security literacy, age is less so. Users aged 65 and older were seemingly just as knowledgeable as users in the age range of 18-29; while online literacy bias in general is weighted toward younger users, the Pew survey suggests that overall there is a shared standard of what we know and what we don’t know.

Link: How David Bowie helped my autistic son become himself.

I’ll freely admit that I didn’t make it through this without some tears…

I don’t think it’s saying too much to suggest that Bowie helped Benj discover his humanity. Like all of us, the parents, the therapists, and teachers, he was drawing the child’s spirit out into the light of relations that could sustain it. But the opposite is true too. Bowie the wild man, the extravaganza, the extraterrestrial—he was, as he always knew, in desperate need of being humanized, of being understood as merely, fully, human. Everything he did was about its being all right to be yourself—that’s what Benj heard and, in the mirror he held to himself, allowed Bowie again to be.

Less School

This is going to put me at odds with many of my more liberal friends, but I do see the justification for the argument here as well as “The Case Against Education.” Education is big business and we’re not educating our children (or adults) in the US in a way that best suits their future or the future of our republican democracy.

So what is really going on? Caplan offers plausible evidence that school functions to let students show employers that they are smart, conscientious, and conformist. And surely this is in fact a big part of what is going on. I’ve blogged before one, and in our book we discuss, some other functions that schools may have served in history, including daycare, networking, consumption, state propaganda, domesticating students into modern workplace habits.

Learning to Summize?

 

Take a picture of a textbook page and instantly get summaries, analyses, videos, flashcards and annotations.

Source: Summize

I’ve been playing with this new app this morning. It’s … interesting and has caused me to stop and think.

And to think… I had months (if not years) of instruction time at elementary, middle, high school, and college levels training me to summarize, analyze, annotate and make flashcards.

Remember SQ3R? I certainly do.

  • Survey
  • Question
  • Read (R1)
  • Recite (R2)
  • Review (R3)

We had entire classes and tests on “study skills.” Barf. If anything, SQ3R etc made me detest reading textbooks at an early age even more than I already did (which is why I rarely if ever used them as a middle school teacher). Granted, reading and processing a college textbook is much different than reading for pleasure (which is probably one of the reasons why I became a Religion major and find escape from textbooks).

Here’s an example of Summize’s “Bias Analysis” from a page I randomly took from The Practice of Adaptive Leadership:

2016-05-18 09.50.18

It doesn’t get all the words right, but come on… that’s pretty interesting when you consider anyone can do that from their iPhone. This is from the “Concept Analysis” feature, which basically gives you the rundown of a page’s main concepts for review:

2016-05-18 09.56.20

There’s also an automatic flashcard builder or you can snap your own essays and do quick grammar checks. You see where I’m going.

We thought desktops would revolutionize the classroom when I was a kid in the 80’s. Then it was CD-ROMs and laptops in the 90’s. Then it was personal digital assistants in the 00’s. Now we realize that the mobile revolution is the real instigator for substantive technological impact in education.

Mobile is just the beginning as we venture into an augmented / virtual reality world where information will, literally, be on our retinas in the blink of an eye (no fingertips needed this time).

It pains me to consider that concepts and skills such as spelling, punctuation, state capitols, multiplication tables, cursive writing (well, not really that one), lines of Shakespeare etc may not be required to be stored in our brains in the near future … if now. Or perhaps even the larger concepts of knowing how to look at a page of a textbook, get out your various colored highlighters, and go to work summarizing and finding the “main ideas” aren’t requirements for “successful” reading and processing.

Sure, they’re good things to know… but so were knowing star charts, how to hunt skin squirrels, and morse code at one time (not that all three aren’t still very valuable in certain circumstances).

Does this make post-millennials (or whatever we are going to call them) any more “lazy” than the Baby Boomers? I don’t think so. I know plenty of Baby Boomers who decry having to carry a mobile phone yet learn to love FaceTiming their family after a few weeks of doing so.

The older I get, the more I realize that conceptions of required understandings, skills, concepts etc are all in constant flux. Perhaps we benefited someway in the 20th century U.S. by having a rather sturdy monoculture that gave us a clear “common core” roadmap of things that every person of good standing should know and know how to do.

But I’ll take this evolving 21st century realization that normative culture isn’t the best path for the education of our children. Perhaps technological tools can help us rise above the barriers that very real socio-economic barriers of schools and home circumstances that previously segmented our society from the outset and didn’t give many kids the opportunity to “be all that they can be.”

“Random” prime numbers and human projections

“So just what has got mathematicians spooked? Apart from 2 and 5, all prime numbers end in 1, 3, 7 or 9 – they have to, else they would be divisible by 2 or 5 – and each of the four endings is equally likely. But while searching through the primes, the pair noticed that primes ending in 1 were less likely to be followed by another prime ending in 1. That shouldn’t happen if the primes were truly random –  consecutive primes shouldn’t care about their neighbour’s digits.”

Math, philosophically, is spooky.

Does it “really” exist in the cosmos or is it (like most things we consider to be intrinsic to the universe) a human projection based on our finite nature?

The “Mystery” of Good Schools

“The authors of these two books demonstrate that grand ideas cannot be imposed on people without their assent. Money and power are not sufficient to improve schools. Genuine improvement happens when students, teachers, principals, parents, and the local community collaborate for the benefit of the children. But a further lesson matters even more: improving education is not sufficient to “save” all children from lives of poverty and violence. As a society, we should be ashamed that so many children are immersed in poverty and violence every day of their lives.”
