Coming from another angle, I’m in the middle of reading Daniel Goleman’s book Focus: the hidden driver of excellence, in which he discusses the implications of extensive presence of technology on childrens’ (and adults’) cognitive development, especially in relation to developing and sustaining focus, which in turn affects performance. I also just read this article in the Guardian on how so much online time is affecting childrens' levels of empathy.
I was also reminded of an ASCD webinar I participated in last year, in which Michael Fullan presented his ideas on technology and education. He is critical of the way in which educational systems have jumped on the band wagon of technology, but largely to the exclusion of pedagaogy: 'Investment in technology has been primarily a matter of acquisition—buy, buy, buy. Not a matter of how it could accelerate learning.' He argues that technology is the way forward but that the solution lies in the concentration of the three forces of pedagogy, technology and change knowledge.
