Today I was reading about the Dead Sea Scrolls, which were discovered in many pieces. The first people to work on them decided to use a new wonder-product - Sellotape - to join the pieces together. The only problem is that the Sellotape was far more destructive to the Scrolls than they could ever have imagined, and much of the current preservation work is spent trying to put right the wrong done to the delicate parchments by the Sellotape.
This made me think of the use of technology as a magical remedy for the improvement of language teaching. It may improve things in the short-term, but then we may spend a disproportionate amount of time later on trying to put right the wrongs that it has done by its improper or careless use.
It also brings to mind what Gove is doing with education at the moment. Using new wonder-solutions, the latest trendy ideas, to stick together the pieces of a system that needs improvement. But for how long are we going to be painstakingly cleaning off the residues of this botched attempt?
