I’m re-reading Howard Gardner’s Changing Minds: The Art and Science of Changing Our Own and Other People’s Minds. (The first three chapters are required reading for the Change Management class that I teach.) He describes how skills and capacities are valued differently at various times and under varying circumstances. He points to inventions like the printing press and the computer which can alter the abilities that are valued or deemed important in a culture. It is comforting because, as he goes on to say, individuals are not equally “smart” or “dumb” under all circumstances – they just have different intelligences that may be regarded as important or devalued under different circumstance. But it is also an example of why Neil Postman’s ten principles for technology education are important to consider. The tools shape us by changing the intelligences we value.
