This is a perfectly good knob to use. Grab it, turn it, pull (or push), and the door swings open. So it meets your needs. Or does it? Does it meet ALL your needs, your universal set of needs, needs that arise in different situations, different contexts?
Well, suppose you are rushing down the corridor in your office building, with a cup of coffee in one hand, the other clutching a folder or file. You are late. You run up to the door and see the same round knob as above. Can you open the door with it when both your hands are “occupied”?
Or would this design do a better job:
Because with this, you can lean down a bit, and push the handle with your elbow. If neither hand is occupied, you still grab, turn, push (or pull) as always. The handle meets your diverse needs, needs that rise in different situations. It has, what we call, a “universal design”.
It took a long time for people to become conscious of needs that go beyond those that are mainstream and taken for granted. Like people using wheelchairs. When they first built houses and office buildings, people used stairs or steps to climb up the building to get to upper floors. This alienated a population of people who were unable to use their legs. They used wheelchairs in hospitals. Maybe a few in their own homes. But by and large, they were kept out of office buildings and even prevented to do social visits. They couldn’t pay their bills, draw their money from banks, or perform any transactions. Or see visit relatives and friends.
It has been only 4 decades that their needs were acknowledged. In the beginning, it was expensive to redesign and rebuild buildings and homes for people with such special needs. So ramps were “attached” on the side of the buildings for such “special” people. Like this:
“We” soon became associated with the “normal” population that could use steps, and “They” with “those” people who couldn’t. Handicapped people. Those “poor people” who couldn’t walk. This led to the exclusion of a part of mankind to a lower, somewhat lesser conceptual level where the handicapped felt like outcasts in their own midst. They were made to enter from the side rather than from the front, “like the rest”. It compromised their self-dignity.
The Inclusion Movement rallied against the tradition of “Exclusion” for decades. Until the day came when leading architects and designers began envisioning buildings in which various options were made available to negotiate higher floors. Technology, too, came to the rescue. So elevators and escalators took over. No side-entrances for special needs was necessary. ALL needs were human needs. And ALL needs had to be equally respected, equally addressed. Everyone deserved to enter from the front. And if ramps were needed to enter a building, then the ramps would be integrated into the design of the building from its very conception. They would run alongside the steps. All who enter a building should enter as equals. And all buildings and homes should be designed for such “universal access”.
This same idea applies as much to education as to buildings and door-knobs. Learners have different needs. And these may vary among individuals of different ages and genders as much as within anyone’s given lifetime.
Can educational courseware be designed in such a way that they address the needs of (a) gifted learners (b) disadvantaged learners (c) and all learners that fall between these two extreme poles?
I have tried to meet the demands of Universal Design in Learning in the educational courseware I share in Karismath Insights Videos.
I suggest you read my two other posts on What is visual mediation? and Teaching mathematics by visual scaffolding to fully appreciate the theory behind the videos.
