Today, we go to correspondence school.
The University of Houston's College of Engineering
presents this series about the machines
that make our civilization run, and the people
whose ingenuity created them.
Here's a 1900 handbook, Mechanics' Pocket Memoranda.
It has the usual stuff in front -- trig functions, logarithms, conversion tables.
But deeper into the book we find a set of mini-engineering textbooks with wonderful
drawings. The whole book is only 3-1/2 by 5 inches. It really does fit in my pocket.
Then I notice: it was published by the International Correspondence Schools -- better
known as ICS. That got my attention. In 1946, I was doing badly in high school when
a successful land surveyor took me under his wing and lent me his old ICS course on
drafting. I started doing drawings and handing them in to him.
And a world opened up. No instructor was talking at me -- obstructing my view of the
subject. I was on my own, and education made sense. This old book brings back the
sunburst of light I felt back then -- freedom to learn as rapidly as I was capable of
learning. And, of course, that special beauty of machine drawings.
One website about distance learning begins its timeline with Paul's Epistles to the Church
-- we've been trying to teach one another with written messages for millennia. But America
began an intense concentration on mail-order schooling near the end of the nineteenth century.
Anna Ticknor, daughter of a Harvard professor, founded of the movement in 1873. She created
the Society to Encourage Studies at Home. She ran it 'til she died 24 years later.
Right on her heels a number of large universities -- as well as the Chautauqua movement -- took
up the idea. The University of California was a latecomer in 1910, but it soon had the largest
academic correspondence program in the country.
The International Correspondence School was another matter. It began in 1890 as a home study
course offered by the Pennsylvania Colliery Engineer School of Mines. Its Scranton headquarters
was a four-story medieval castle complete with turrets. By 1900, its huge in-house printing
press was producing four tons of course notes each week. ICS could already boast a
A picture in the end of my handbook shows a workman studying in his cramped boardinghouse room.
And I know this is no advertising gimmick. I lived in all too many of those rooms, long ago.
I know why he's focused so intently upon his notes.
Now we speak of distance learning, delivered by Internet, not by the postman. Its form is still
evolving. Maybe it can become what the old correspondence course once was. Here's another old
book, a manual on how to write correspondence courses.
It says: "Questions should require the student to think, not simply recollect or repeat."
Then it offers an example of a good question,
"Why is a kick delivered to a dog a stimulus and one delivered to a football not a stimulus?"
Well, while you mull that one, I'm going back to look at pictures in this old ICS handbook.
I want to relive the kick they once delivered to me.
