The changing nature of literacy. Part 4: Models & Literacies

This post is the fourth and last part in a four-part series on how education delivery is changing, and the set of literacies required in today’s world. Part 1 looked at textbooks; Part 2 at direct instruction/lecturing; Part 3 at computer learning.. This post looks at learning models and types of literacy.

 

Literacy. What does it mean?

Diabetes - its role in cognitive impairment and dementia

There was an alarming article recently in the Guardian newspaper. It said that in the UK, diabetes is now nearly four times as common as all forms of cancer combined. Some 3.6 million people in the UK are thought to have type 2 diabetes (2.8 are diagnosed, but there’s thought to be a large number undiagnosed) and nearly twice as many people are at high risk of developing it. The bit that really stunned me? Diabetes costs the health service roughly 10% of its entire budget.

A new resource for Alzheimer's caregivers

I recently reported on a long-running study that found that husbands or wives who care for spouses with dementia are six times more likely to develop Alzheimer’s themselves than those whose spouses don't have it. The most likely cause for this is the great stress of caregiving. Both stress and depression increase the risk of Alzheimer’s, and both are common (well, stress is inescapable!) among caregivers.

Why learning is harder as we get older

Children learn. It’s what they do. And they build themselves over the years from wide-eyed baby to a person that walks and talks and can maybe fix your computer, so it’s no wonder that we have this idea that learning comes so much more easily to them than it does to us. But is it true?

There are two particular areas where children are said to excel: learning language, and learning skills.

Variety is the key to learning

On a number of occasions I have reported on studies showing that people with expertise in a specific area show larger gray matter volume in relevant areas of the brain. Thus London taxi drivers (who are required to master “The Knowledge” — all the ways and byways of London) have been found to have an increased volume of gray matter in the anterior hippocampus (involved in spatial navigation). Musicians have greater gray matter volume in Broca’s area.

The changing nature of literacy. Part 1: Textbooks

As we all know, we are living in a time of great changes in education and (in its broadest sense) information technology. In order to swim in these new seas, we and our children need to master new forms of literacy. In this and the next three posts, I want to explore some of the concepts, applications, and experiments that bear on this.

The most effective learning balances same and different context

I recently reported on a finding that memories are stronger when the pattern of brain activity is more closely matched on each repetition, a finding that might appear to challenge the long-standing belief that it’s better to learn in different contexts. Because these two theories are very important for effective learning and remembering, I want to talk more about this question of encoding variability, and how both theories can be true.
