We all get overloaded from time to time, especially toward the end of a term when your todo list turns from being measured by points to metres. We all have our own capacity to deal with the issues at hand, and the ideas behind Cognitive Load Theory (CLT) attempt to maximise our bandwidth while streamlining the signals.
The origins of the theory go back to the 1980s when a plethora of digital innovations changed how presentations were done in the business world. This trickled down in the following decades into how teachers presented ideas, moving away from blackboard and Over-Head Projectors to digitalised PowerPoint presentations. As with any new innovation, form overcame function, and for a period in the early noughties, I swear it must have been the law to cram as many animations and sound effects into every PowerPoint, and reading every word from the screen aloud was mandatory.
