At one of many current conferences, I used to be shocked to see my co-speaker come with out a PowerPoint presentation. How might somebody even think about talking with out it! Up to now 20 years, this has turn into virtually the norm.
Again in class, the blackboard was once the centre of studying. It could come to life, fairly actually, with the academics scribbling and underlining the “must-know” factors on it. (Inventory picture/For representational functions)
As a substitute, my buddy and colleague when known as to the stage, pulled up the display screen and acquired it folded, rummaged by means of his pockets, and got here up with a few chalks, with which he wrote the title of his lecture on the good-old blackboard that lay hidden beneath the white display screen and, I need to say, the viewers, comprising psychological well being professionals from all around the nation, listened intently and with curiosity proper until the tip of his presentation.
This incident took me again to the time I used to be in class, the place the blackboard was once the centre of studying. It could come to life, fairly actually, with the academics scribbling and underlining the “must-know” factors on it.
The identical blackboard would really break right into a riot of colors when our biology trainer would use colored chalks to attract a diagram of the cell, the muse of life. She would come to highschool an hour earlier than the primary class within the morning, and would draw the diagram earlier than the scholars trooped in.
The blackboard was our window to fixing the tough-looking mathematical issues or the physics’ numericals. It was our eye into the outer house from the photo voltaic system to the Milky Manner.
The quintessential blackboard was in a special avatar in faculty, the place it was within the type of an extended black sheet that was mounted on pulleys, one on the prime and the opposite on the backside. There was a deal with on the backside by which the blackboard might be moved upwards. This modification supplied the benefit to the scholars of the content material written on it staying for an extended time earlier than it needed to be erased.
The trainer would even have his/her arms stuffed with chalk powder and would stroll out of the lecture theatre with the satisfaction of a job properly achieved. We, as college students, too would come out with the awe of getting witnessed a brand new vista of information, fairly actually, constructed word-by-word earlier than our personal eyes.
Does this expertise of educating or being taught examine with the PowerPoint displays of as we speak, outfitted with essentially the most elaborate texts, fascinating photos and movies? The ability of synthetic intelligence (AI) is knocking on our doorways, promising to revolutionise the way in which ideas are understood and info laid out. I dare say, the good-old blackboard should still emerge as a winner, provided that we place confidence in its uncanny potential to impart information in its a number of hues.
