How To Help Your Child’s Brain Grow Up Strong (NPR):

– “Kids who learn two languages young are better able to learn abstract rules and to reverse rules that they’ve already learned,” says Aamodt. “They’re less likely to have difficulty choosing between conflicting possibilities when there are two possible responses that both present themselves. They’re also better at figuring out what other people are thinking, which is probably because they have to figure out which language to use every time they talk to Read the rest of this entry »

Working memory: a better predictor of academic success than IQ?

Working memory is the ability to hold information in your head and

manipulate it mentally. You use this mental workspace when adding up two numbers spoken to you by someone else without being able to use pen and paper or a calculator. Children at school need this memory on a daily basis for a variety of tasks such as following teachers’ instructions or remembering sentences they have been asked to write down.

The main goal of our recent paper published in the Journal of Experimental Child Psychology was to investigate the predictive power of working memory and IQ in learning in typically developing children over a six-year period. This issue is important because distinguishing between the cognitive skills underpinning success in learning is crucial for early screening and intervention.

In this study, typically developing students were tested for their IQ and working memory at 5 years old and again when they were 11 years old. They were also tested on their academic attainments in reading, spelling and maths.

Findings and Educational Implications

The findings revealed that a child’s success in all aspects of learning is down to how good their working memory is regardless of IQ score. Critically, working memory at the start of formal education is a more powerful predictor of subsequent academic success than IQ in the early years.

This unique finding is important as it addresses Read the rest of this entry »

Comparing Working Memory Training & Medication Treatment for ADHD

Working memory (WM) is the cognitive system responsible for the temporary storage and manipulation of information and plays an important role in both learning and focusing attention. Considerable research has documented that many children and adults with ADHD have WM deficits and that this contributes to difficulties associated with the disorder. For an excellent introduction to the role of WM deficits in ADHD, click here.

A simple example illustrates the importance of WM for particular academic tasks. Try adding 3 and 9 in your head. That was probably easy for you. Now trying adding 33 and 99. That was probably more difficult. Finally, try adding 333 and 999. This is quite challenging for most adults even though each calculation required is trivially easy. The challenge occurred because you need to store information – the sum of 3+9 in the one’s column and then ten’s column – as you process the remaining part of the problem, i.e., 3+9 in the hundred’s column, and this taxed your WM. If your WM capacity was exceeded, you could not complete the problem successfully.

This simple problem also illustrates the difference between short-term memory (STM) and WM. Short-term memory simply involves retaining information in mind for short periods of time, e.g., remembering that the problem you need to solve is 333+999. Working memory, in contrast, involves mentally manipulating – or ‘working’ with – retained information and comes into play in a wide range of learning activities. For example, to answer questions about a science chapter, a child not only has to correctly retain factual information but must mentally work with that information to answer questions about it. Thus, when a child’s WM capacity is low relative to peers, academic performance is likely to be compromised in multiple areas.

Because WM deficits play an important role in the struggles experienced by many individuals with ADHD, it is important to consider how different interventions address this aspect of the disorder. In this study, the authors were interested in comparing the impact of Working Memory Training and stimulant medication treatment on the WM performance of children diagnosed with ADHD.

Participants were 25 8-11 year-old children with ADHD (21 boy and 4 girls) who were Placebo effect, mind hacksbeing treated with stimulant medication. Children’s memory performance was assessed on 4 occasions using the Automated Working Memory Assessment (AWMA), a computerized test that measures verbal short-term memory, verbal working memory, visuo-spatial short-term memory, and visuo-spatial working memory.

At time 1, the assessment was conducted when children had been off medication for at least 24 hours. The second assessment occurred an average of 5 months later and when children were on medication. The third assessment occurred after children had completed 5 weeks of Cogmed Working Memory Training using the standard training protocol (see below). The final assessment occurred approximately 6 months after training had ended. This design enabled the researchers to make the following comparisons:

– WM performance on medication vs. off medication (T1 vs T2)
– WM performance on medication vs. after training (T2 vs. T3)
– WM performance immediately after training ended vs. 6 months following training (T3 vs. T4)

This final comparison provided information on whether any benefits provided by the training had endured.

In addition to measuring STM and WM at each time point, measures of IQ were collected at times 1, 2, and 3.

Working Memory Training

WM training was conducted using the standard Cogmed training protocol with each child Cogmed working memory trainingcompleting 20-25 training sessions within a 25 day period. The training requires the storage and manipulation of sequences of verbal, e.g., repeating back a sequence of digits in reverse order, and/or visuo-spatial information, e.g., recalling the location of objects on different portions of the computer screen.

Difficulty level is calibrated on a trial by trial basis so the child is always working at a level that closely matches their performance. For example, if a child successfully recalled three digits in reverse order, on the next trial he had to recall four. When a trial was failed, the next trial was made easier by reducing the number of items to be recalled. This method of ‘adaptive training’ is thought to be a key element because it requires the child to ‘stretch’ their WM capacity to move through the program.

Carnival of Education #159: Briefing the Next US President on 35 Issues

Dear Mr or Mrs Next US President,

Thank you for stopping during recess for a quick study sessiMeditation School Studentson. 35 educators have collaborated to present this Carnival of Education as a useful lesson plan for you and your education policy team on what our real concerns and suggestions are.

In case this is your first visit to our SharpBrains blog, let me first of all point out some useful resources to stay sane during the rest of the campaign: selected Brain Teasers, a list of 21 great Brain Books, over a dozen interviews with leading scientists on learning and brain-based topics, and more.

Without further ado, let’s proceed to the issues raised. We hope they provide, at the very least, good mental stimulation for you and your advisors.

Education as a System

The First Step Is Failure

Joanne Jacobs, educator, blogger and author of Our School: The Inspiring Story of Two Teachers, One Big Idea and the Charter School That Beat the Odds, participates today in our Author Speaks Series with an excellent article on how “Schools won’t improve until administrators and teachers can admit the problems, analyze what’s going wrong and try new strategies. Students won’t improve if they think they’re “special” just the way they are.” Enjoy, and feel free to add your comment to engage in a stimulating conversation.Our School: Joanne Jacobs

The First Step Is Failure
By Joanne Jacobs

When self-esteem became an education watchword in 1986, I thought it was a harmless fad. I was wrong: It wasn’t harmless. Many teachers were persuaded that students should be pumped up with praise, regardless of their performance. Schools lowered expectations so students couldn’t fail. Everyone got an “I Am Special” sticker. Till the standards and accountability movement kicked in, students often were judged by how they felt about learning not by whether they’d actually learned something.
