11. Less & More
Less paper, more pixels.
Less conformity, more disruption.
Less single source, more crowd source.
Less compliance, more thinking.
Less just in case, more just in time.
Less about tests, more about being tested.
Less compliance, more engagement &
empowerment.
This is the defining challenge of our times in public school.
This inescapable truth sets the direction
Crowd Source the HardwareThe print capacity model dictates that for everything we use we must provide a copy to ensure equity.What if we allowed students to use their own equipment and only provided for those who could not afford it?
The only solution then is to wait – wait until that day when we can afford to buy every student the same device.Is it really more equitable to say that no one has access to technology until everyone can have the same thing?It’s not about the device, its about what we do with it.The only solution then is to wait – wait until that day when we can afford to buy every student the same device.Is it really more equitable to say that no one has access to technology until everyone can have the same thing?It’s not about the device, its about what we do with it.The only solution then is to wait – wait until that day when we can afford to buy every student the same device.Is it really more equitable to say that no one has access to technology until everyone can have the same thing?It’s not about the device, its about what we do with it.The only solution then is to wait – wait until that day when we can afford to buy every student the same device.Is it really more equitable to say that no one has access to technology until everyone can have the same thing?It’s not about the device, its about what we do with it.
How does denying children access to technology in the name of equity serve their needs?Without access they will never have the opportunity to develop the skills that their more appropriately resourced peers have at home every day.
