This is a very interesting suggestion that I may try out. To make sure I see the effect hope to do a before and after test. And do it with all my four sons.
But first I have some questions:
It could be that he just natively has a good working memory. I was always surprised by the very good episodic memory of my oldest son. And the rote memory of my second oldest. And the motor memory of my third. All untrained.
Are you sure this provides a benefit/is wirth the effort? We live in a digital age where we do have access to lots of short-term memory aids. - This is a genuine question I'm not sure on myself.
My personal guess would be the training itself doesn't help much. But the memory techniques do. Why? Because I playd lots of Concentration Game with all my sons and it is very difficult for all of them. But after I introduced building stories around the visible cards they were able to pick up the technique and at least improve somewhat.
I'm sure genetics plays a big role my son's strong working memory, but his progress while training has been fast enough that I'm more than 90% confident that the training has significantly helped. Memory aids (like spell check) do reduce the value of having a good working memory, but don't come close to negating it especially for children who will be taking many closed book exams, and because having to keep looking up things (like the syntax for a for loop) costs time, attention, and flow.
I continually train my ten-year-old son’s working memory, and urge parents of other young children to do likewise. While I have succeeded in at least temporarily improving his working memory, I accept that this change might not be permanent and could end a few months after he stops training. But I also believe that while his working memory is boosted so too is his learning capacity.
I have a horrible working memory that greatly hindered my academic achievement. I was so bad at spelling that they stopped counting it against me in school. In technical classes I had trouble remembering what variables stood for. My son, in contrast, has a fantastic memory. He twice won his school’s spelling bee, and just recently I wrote twenty symbols (letters, numbers, and shapes) in rows of five. After a few minutes he memorized the symbols and then (without looking) repeated them forward, backwards, forwards, and then by columns.
My son and I have been learning different programming languages through Codecademy. While I struggle to remember the required syntax of different languages, he quickly gets this and can focus on higher level understanding. When we do math learning together his strong working memory also lets him concentrate on higher order issues then remembering the details of the problem and the relevant formulas.
You can easily train a child’s working memory. It requires just a few minutes of time a day, can be very low tech or done on a computer, can be optimized for your child to get him in flow, and easily lends itself to a reward system. Here is some of the training we have done:
The key is to keep changing how you train your kid so you have more hope of improving general working memory rather than the very specific task you are doing. So, for example, if you say a sequence and have your kid repeat it back to you, vary the speed at which you talk on different days and don’t just use one class of symbols in your exercises.
