The key point for teachers and principals and parents to realize is that maintaining attention is a skill. It has to be trained, and it has to be practiced. If we cater to short attention spans by offering materials that can be managed with short attention spans, the skill will not develop. The “attention muscle” will not be exercised and strengthened. It is as if you complain to a personal trainer about your weak biceps and the trainer tells you not to lift heavy things. Just as we don’t expect people to develop their biceps by lifting two-pound weights, we can’t expect them to develop their attention by reading 140-character tweets, 200-word blog posts, or 300-word newspaper articles.
Barry Schwartz really have a good point here – the ability to pay attention over a longer period of time must be trained and is possibly the most important skill we might have in the future.
