Of 3D Printing, Lego Bricks and Stuffs...

Teaching is so filled with help these days. I do formative and summative assessments online with my students. I keep in touch with my students via the communication network... email, What's App, iMessage.... I can't keep up with all the new apps. I collaborate with students in the cloud which comes in all kinds of names these days. Instagram, Twitter, Facebook.... the list seems endless... There are Dropbox, Box, Drive... again another long list. From the big bulky desktops, we have moved to chromebooks and who knows, perhaps tablets will be making their presence felt soon too. They are already in many places.

I use AppleTV to transmit lessons on the screen, write on little tablets instead of chalkboards. Mind maps make appearances with great ease because apps make it possible. Videos and animations too with great frequency. Students submit homework online. I still use the exercise books, though but they seem such a waste. Papers come from trees and we waste so many pages in an exercise book each year.

When I started teaching, cyclostyling was how we did the printing. You type on stencils with the clunky typewriter and had this red liquid which worked like an eraser for mistakes. It was a wow moment when dot matrix printers made their appearances at work places. Then came the laser printers. These days I mostly print my own worksheets. But most of the time, it's a mix of digital screens and papers. I try to minimise the use of papers whenever possible.

Then the Overhead Projectors came about.... followed by the visualisers and projection panels. Then as computers became more common, projectors made their presence felt. Chalkboards will probably be a thing of the past soon. LED screens, AppleTV,  Chromecast, smart tv and the most recent addition is the 3D printer. It is quite amazing what a 3D printer can do. From chocolates to titanium, these printers are able to print I have read. And they print even complete houses too, cars as well and homemade toys. As a kid, I think I never imagined such changes. Goes to show how small my world is.

My students play with Lego bricks, lego with brains, NXT, EV3... And these are for co-curricular activities. When I was a student, I knew only of one type of band and my school band was already quite special back in the early days in the sense we had a bagpipe section. These days kids in my school are spoilt for choice... 24 Seasons Drums, Chinese Orchestra, Brass Band and even a Symphony Orchestra. 

Lessons used to to teacher dependent within the four walls of a building. These days we have the world wide web to help us. All kinds of gurus reside there, in places like Khan Academy, Crash Course, UdaCity, Coursera and so on. If you want a visual instruction for a hobby, YouTube is available. We are even beginning to have our own homegrown versions. Recently students in Kedah were given access to Kedah ETutor where the video content is based on our very own curriculum.

However I guess too, if we are to ask the generation before us how it was like... I think their tale will probably be in the same tone too, albeit about different things. After all, theirs was a generation of huge leap in transportation and communication too....

But despite all these amazing development, I wonder too whether we have all become wiser and more resilient? Point to ponder.
