Traumatic brain injury is the biggest killer of young adults and children in the U.S., and in a year more Americans suffer a TBI than are diagnosed with breast, lung, prostate, brain and colon cancer combined. There are many causes of TBI, but one of the more preventable is that of sports concussion.

Planning memory contains your plans and goals (such as, “I must pick up the dry-cleaning today”; “I intend to finish this project within three months”). Forgetting an appointment or a promise is one of the memory problems people get most upset about.

Research; study; learning; solving problems; making decisions — all these, to be done effectively and efficiently, depend on asking the right questions. Much of the time, however, people let others frame the questions, not realizing how much this shapes how they think.

In the education world, fixed mind-set is usually contrasted with growth mind-set. In this context, fixed mind-set refers to students holding the idea that their cognitive abilities, including their intelligence, are set at birth, and they just have to accept their limitations. With a growth mind-set, however, the student recognizes that, although it might be difficult, they can grow their abilities.

A growth mind-set has been associated with a much better approach to learning and improved academic achievement, but new research suggests that this difference has been over-stated.

This post is the third 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 the changing world of textbooks; Part 2 looked at direct instruction/lecturing. This post looks at computer learning.

In the last part I talked about retrieval structures and their role in understanding what you’re reading. As promised, this month I’m going to focus on understanding scientific text in particular, and how it differs from narrative text.

The conventional view of brain development has been that most of this takes place in utero and in the first three years, with the further development continuing until the brain is fully mature at around 10-12 years of age. The turbulence of adolescent behavior has been deemed to be mostly caused by hormonal changes. Piaget, who identified four stages of cognitive development, assessed that his highest stage — that of formal, abstract reasoning — occurred around 13-14 years (although not everyone reaches this level, which requires appropriate education).

Let’s talk about the cognitive benefits of learning and using another language.

In a recent news report, I talked about the finding that intensive learning of a very novel language significantly grew several brain regions, of which two were positively associated with language proficiency. These regions were the right hippocampus and the left superior temporal gyrus. Growth of the first of these probably reflects the learning of a great many new words, and the second may reflect heavy use of the phonological loop (a part of working memory).

Intelligence in a cultural context

One theory of intelligence sees intelligence in terms of adaptiveness. Thus: "What constitutes intelligence depends upon what the situation demands" (Tuddenham 1963). Intelligence in these terms cannot be understood outside of its cultural context. Naturally to us it may seem self-evident that intelligence has to do with analytical and reasoning abilities, but we are perceiving with the sight our culture taught us.

Compulsory Education: When it starts and how long it lasts

Around the world, for the most part, compulsory schooling starts at 6, although some start at 7, and a very few at 5 or even younger. There is less consensus about how long compulsory education should last, but 9 years is the most common length, with 10 years running a close second.
