The Mobile App for learning existed pre-Internet. It was simply called a wagon.
This ‘school on wheels’ known as the Jesup Wagon was an invention of one George Washington Carver, a former slave.
A scientist, better known for the innovation we call ‘crop rotation’ and also peanuts, Carver loaded his ‘horse-drawn classroom’ and laboratory with seeds and travelled to where the need was. His students were former slaves who had become sharecroppers.
We could all use this to get some perspective, especially when we think we need fancy technology to connect knowledge with students.
