Found via the Twitter stream today is a link to The New York Times visual timeline of classroom technology and how it has evolved over the last few centuries. Starting in 1650 with a simple Horn-Book (the finest schoolroom technology of the American Colonial Era), the interactive time line covers 26 of some of the most significant changes in classroom tech, all the way through the 2010 introduction of Apple’s hugely popular tablet computing device, the iPad. Each new invention is displayed with a brief description of the learning tool, and either it’s year of invention, or roughly the years it was used widely. For example, the “Magic Lantern” was once all the rage in Chicago Public Schools between 1870 and World War 1. However, that’s just about where the usefulness of the time line runs out.
While it’s interesting to see the progression of instructional technology, or rather the lack there-of in the 17th and 18th centuries, there’s not much to this timeline beyond a few simple facts. Which got me to thinking; surely a large news media organization like The New York Times could create a much more useful tool for exploring how technology has helped shape instructional practice during the 19th century, or how the rapidly increasing adoption of newer technologies in the later half of the 20th century gave way to a complete inundation of new tools like the interactive whiteboard, the internet, personal computers, and more. Or perhaps, rather than rely on the news organization to provide those details, bring the interactive timeline into your classroom, and start asking some probing questions of your students, and guide them through a deeper exploration of how technology and education have been intermingled in the U.S. in the past 300 years.
For example, according to the timeline of classroom technology, Thomas Edison was quoted as saying that with the invention of the filmstrip projector “books will soon be obsolete in schools. Scholars will soon be instructed through the eye.” Given the filmstrip projector was being used in the classroom in 1925, I’d say Mr. Edison was more than a tad off, considering the majority of students both in k-12 and higher education settings still rely on text, worksheets, and books for their primary means of educational materials. That’s not a critique of his vision, but rather an observation that could lead to an examination of effective instructional modalities, and how technology has played a role in supporting them, or hindering them. Film was rapidly adopted as an entertainment medium in the early 1900s, and while engaging in the theater, many students, and teachers, can often recall sitting through mind-numbing “educational” films that were no better than a dryly written textbook.
If I were to use this timeline in the classroom, I would most likely use it as an assignment for students to choose one of the pieces of technology and delve deeper into the social, educational, and economic impact these pieces of ed tech had on not just schools, but society as well. I would include a few more inventions as well, such as the internet, mobile phones, portable music devices, the CD-Rom, etc. and would probably give the students a road map starting with a few guiding questions:
- “What existing technology did this invention replace or improve upon?”
- “How was this device used in the classroom in it’s own time, and how might it be perceived by students and teachers today?”
- “Did schools struggle to find ways to effectively use each of these pieces of technology when they first came out?”
- “How has this particular piece of technology exist today?”
I’d love to know what other educators think, so feel free to add your own probing questions in the comments below. I’d be even more tempted to create a lesson or two around this topic with a bit more input
