In my 28 years of teaching, I've seen many changes in teaching delivery. Gone are the chalkboards.
Gone also are these- the purple mimeograph machines.
Another one that has gone the way of the T-rex is the globe, once the revolutionary idea of world formation that caused people who supported it to be branded as heretics.
Google Earth, Map Quest, and other programs of the like allow us now to see every nook and crevice of someone's garage in Timbuktu, if they have garages there.
A once proud staple of many classrooms is also making its quiet exit- the overhead projector. Many were the days I left school with multi colored hues on the sides of my hands gained from writing in a rainbow of Vis-aVis markers on the thin plastic rolls.
Those smarty smart boards have negated the need for these heat producing little machines.
Also missing now from libraries are the first things students used to be taught there- the card catalogue.
Another bastion of academia that is hanging on by mere fingernails now is the regular textbook. Because they are expensive and bulky, more and more companies are producing e-books, cheaper, easily accessible, and much more current than the stodgy textbook.
Also gone are reel to reel film projectors, VCR's, cassette tape recorders, and even DVD players. Most new films that need to be shown with our curriculum are delivered via live streaming straight to those ever present smart boards.
Gradebooks and lesson plan books have committed hari-kiri at the dishonor brought to them through the databases that now handle record keeping.
So, as I sort through what is still usable and what needs to be discarded in this graveyard, I am reminded that in all this change, some things remain constant. There will always be kids, there will always be a need for them to learn, and there will always be a need for good teaching. At least I hope so.
