The Evolution of Classroom Technology


Classrooms have come a long way. There’s been an exponential growth in educational technology advancement over the past few years. From overhead projectors to iPads, it’s important to understand not only what’s coming next but also where it all started.

We’ve certainly come a long way but some things seem hauntingly similar to many years ago. For example, Thomas Edison said in 1925 that “books will soon be obsolete in schools. Scholars will soon be instructed through the eye.” I’m pretty sure this is exactly what people are saying these days about the iPad.

Also in 1925, there were “schools of the air” that delivered lessons to millions of students simultaneously. Scroll down to find out how that worked (hint: it wasn’t by using the Internet!)

Here’s a brief look at the evolution of classroom technology. Do you have a piece of technology that you think should be included? Tweet @edudemic or let me know in the comments and I’ll be sure to add it to the timeline! Updated to include items suggested in the comments! Videotapes, Pens, Copiers, and more!

c. 1650 – The Horn-Book

hornbook

Wooden paddles with printed lessons were popular in the colonial era. Perhaps this is where fraternities got the idea? On the paper there was usually the alphabet and a religious verse which children would copy to help them learn how to write.

c. 1850 – 1870 – Ferule

ferule

This is a pointer and also a corporal punishment device. Seems like both this and the Horn-Book had dual purposes in terms of ‘educating’ the youths of that era.

1870 – Magic Lantern

magic-lantern

The precursor to a slide projector, the ‘magic lantern’ projected images printed on glass plates and showed them in darkened rooms to students. By the end of World War I, Chicago’s public school system had roughly 8,000 lantern slides.

c. 1890 – School Slate

school-slate

Used throughout the 19th century in nearly all classrooms, a Boston school superintendent in 1870 described the slate as being “if the result of the work should, at any time, be found infelicitous, a sponge will readily banish from the slate all disheartening recollections, and leave it free for new attempts.’

c. 1890 – Chalkboard

chalkboard

Still going strong to this day, the chalkboard is one of the biggest inventions in terms of educational technology.

c. 1900 – Pencil

pencil

Just like the chalkboard, the pencil is also found in basically all classrooms in the U.S. In the late 19th century, mass-produced paper and pencils became more readily available and pencils eventually replaced the school slate.

c. 1905 – Stereoscope

steroscope

At the turn of the century, the Keystone View Company began to market stereoscopes which are basically three-dimensional viewing tools that were popular in homes as a source of entertainment. Keystone View Company marketed these stereoscopes to schools and created hundreds of images that were meant to be used to illustrate points made during lectures.

c. 1925 – Film Projector

filmstrip

Similar to the motion-picture projector, Thomas Edison predicted that, thanks to the invention of projected images, “books will soon be obsolete in schools. Scholars will soon be instructed through the eye.”

c. 1925 – Radio

radio

New York City’s Board of Education was actually the first organization to send lessons to schools through a radio station. Over the next couple of decades, “schools of the air” began broadcasting programs to millions of American students.

c. 1930 – Overhead Projector

overhead-project

Initially used by the U.S. military for training purposes in World War II, overhead projectors quickly spread to schools and other organizations around the country.

c. 1940 – Ballpoint Pen

ballpoint-pen

While it was originally invented in 1888, it was not until 1940 that the ballpoint pen started to gain worldwide recognition as being a useful tool in the classroom and life in general. The first ballpoint pens went on sale at Gimbels department store in New York City on 29 October 1945 for US$9.75 each. This pen was widely known as the rocket in the U.S. into the late 1950s.

c. 1940 – Mimeograph

mimeograph

Surviving into the Xerox age, the mimeograph made copies by being hand-cranked. Makes you appreciate your current copier at least a little bit now, huh?

c. 1950 – Headphones

language-lab-headset

Thanks to theories that students could learn lessons through repeated drills and repetition (and repeated repetition) schools began to install listening stations that used headphones and audio tapes. Most were used in what were dubbed ‘language labs’ and this practice is still in use today, except now computers are used instead of audio tapes.

c. 1950 – Slide Rule

Slide rule and case

William Oughtred and others developed the slide rule in the 17th century based on the emerging work on logarithms by John Napier. Before the advent of the pocket calculator, it was the most commonly used calculation tool in science and engineering. The use of slide rules continued to grow through the 1950s and 1960s even as digital computing devices were being gradually introduced; but around 1974 the electronic scientific calculator made it largely obsolete and most suppliers left the business.

1951 – Videotapes

vhs-tapes

What would school be without videotapes? (Thanks to Jaume in the comments for reminding me about this one!) The electronics division of entertainer Bing Crosby’s production company, Bing Crosby Enterprises (BCE), gave the world’s first demonstration of a videotape recording in Los Angeles on November 11, 1951. Developed by John T. Mullin and Wayne R. Johnson since 1950, the device gave what were described as “blurred and indistinct” images, using a modified Ampex 200 tape recorder and standard quarter-inch (0.6 cm) audio tape moving at 360 inches (9.1 m) per second. A year later, an improved version, using one-inch (2.6 cm) magnetic tape, was shown to the press, who reportedly expressed amazement at the quality of the images, although they had a “persistent grainy quality that looked like a worn motion picture”.

c. 1957 – Reading Accelerator

reading-accelerator

With an adjustable metal bar that helped students tamp down a page, the reading accelerator was a simple device designed to help students read more efficiently. Personally, this looks like a torture device and is probably the least portable thing to bring along with a book. Is turning the page of a book or holding a book really that difficult?

c. 1957 – Skinner Teaching Machine

skinner-teaching-machine

B. F. Skinner, a behavioral scientist, developed a series of devices that allowed a student to proceed at his or her own pace through a regimented program of instruction.

c. 1958 – Educational Television

education-television

By the early sixties, there were more than 50 channels of TV which included educational programming that aired across the country.

1959 – Photocopier

photo-copier

Xerographic office photocopying was introduced by Xerox in 1959, and it gradually replaced copies made by Verifax, Photostat, carbon paper, mimeograph machines, and other duplicating machines. The prevalence of its use is one of the factors that prevented the development of the paperless office heralded early in the digital revolution[citation needed].Photocopying is widely used in business, education, and government. There have been many predictions that photocopiers will eventually become obsolete as information workers continue to increase their digital document creation and distribution, and rely less on distributing actual pieces of paper.

c. 1960 – Liquid Paper

liquid-paper

A secretary made this white liquid in her kitchen and sold the company to Gillette for about $50 million. The rest is (redacted) history!

1965 – Filmstrip Viewer

filmstrip-viewer

A precursor to the iPad perhaps, this filmstrip viewer is a simple way to allow individual students watch filmstrips at their own pace.

c. 1970 – The Hand-Held Calculator

calculator

The predecessor of the much-loved and much-used TI-83, this calculator paved the way for the calculators used today. There were initial concerns however as teachers were slow to adopt them for fear they would undermine the learning of basic skills.

1972 – Scantron

scantron

The Scantron Corporation removed the need for grading multiple-choice exams. The Scantron machines were free to use but the company made money by charging for their proprietary grading forms. Sneaky stuff.

1980 – Plato Computer

plato-computer

Public schools in the U.S. averaged about one computer for every 92 students in 1984. The Plato was one of the most-used early computers to gain a foothold in the education market. Currently, there is about one computer for every 4 students.

1985 – CD-ROM Drive

cd-rom-drive

A single CD could store an entire encyclopedia plus video and audio. The CD-ROM and eventually the CD-RW paved the way for flash drives and easy personal storage.

1985 – Hand-Held Graphing Calculator

graphing-calculator

The successor to the hand-held calculator (see above), the graphing calculator made far more advanced math much easier as it let you plot out points, do long equations, and play ‘Snake’ as a game when you got bored in class.

c. 1999 – Interactive Whiteboard

whiteboard

The chalkboard got a facelift with the whiteboard. That got turned into a more interactive system that uses a touch-sensitive white screen, a projector, and a computer. Still getting slowly rolled out to classrooms right now, betcha didn’t know they were first around in 1999! (I didn’t know that, at least)

2005 – iClicker

clickers

There are many similar tools available now, but iClicker was one of the first to allow teachers to be able to quickly poll students and get results in real time.

2006 – XO Laptop

xo-laptop

The ‘One Laptop Per Child’ computer was built so it was durable and cheap enough to sell or donate to developing countries. It’s an incredible machine that works well in sunlight, is waterproof, and much more. Learn more.

2010 – Apple iPad

ipad

Just like the original school slate, could the iPad bring Thomas Edison’s statement to life? Could the iPad make it so “scholars will soon be instructed through the eye.” Only time will tell.

Google Play Store vs the Apple App Store: by the numbers (2015)


When it comes to mobile ecosystems, there are two giants locked in a battle, not only for revenue, but also for the hearts and minds of developers and consumers alike. They are of course Google and Apple. Google’s mobile operating system is Android along with the Google Play Store, while Apple’s offering is iOS along with the Apple App Store (iTunes).

Both Google Play and iTunes offer apps, music, books, films, and TV series. But which is better? Here is a look at the two stores to see how they compare.

So with both stores offering at least 1 million apps and both notching-up downloads measured in the billions, what other deciding factors are there that distinguish one store from the other.

Tablets in schools: coding, creativity and the importance of teachers


From September, coding will be part of the primary and secondary education curriculum in the UK, as part of wider changes designed to boost computer literacy alongside reading, writing and maths skills for British children.

Some independent schools are already providing a glimpse at the potential. Which is why I recently found myself in Cambridge, watching a classroom of Year 5 girls – 9-10 year-olds – practising their programming skills on iPad apps like Hopscotch, Move the Turtle and Kodable.

Kindergarteners Who Share iPads May Perform Better: Study


Students perform better if they share an iPad with another student as opposed to having one all to themselves, according to a new study.

Though schools nationwide have ramped up their efforts to introduce technology in the classroom, there’s just a small body of evidence on the benefits for students. Now a new study suggests that iPads do have a role in academic performance, but the effect may be greater when students collaborate.

Do Tablets in the Classroom Really Help Children Learn?


Mobile devices as teaching tools are becoming a more and more common part of the American education experience in classrooms, from preschool through graduate school. A recent Pew Research Center survey found that 58% of U.S. teachers own smartphones — 10 percentage points higher than the national average for adults. Those teachers are building that tech-savviness into their lesson plans, too, by embracing bring-your-own-device policies and leading the push for an iPad for every student. In 2013, an estimated 25% of U.S. schools had BYOD policies in place and it’s reasonable to assume those numbers have risen in the past two years.

What do these mobile devices really add, though? Is there more to this tech trend than just grabbing the attention of students? Is mobile technology boosting classroom instruction, or is it all just a flashy way to accomplish the same things as analog instruction?
