What are external memory aids?
External memory aids include such strategies as:

Song is a wonderful way to remember information, although some songs are better than others. Songs that help you remember need to have simple tunes, with a lot of repetition -- although a more complex tune can be used if it is very familiar. Most importantly, the words should be closely tied to the tune, so that it provides information about the text, such as line and syllable length. You can read more about this in my article on Music as a mnemonic aid, but here I simply want to mention a few specific songs designed for teaching facts.
To choose a strategy, you must assess the situation. In this case, this may mean an evaluation of a written text. Let's look at how you might evaluate text.
We can classify text at one of three different levels, according to its structure and density1:
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.
Elaborative interrogation is a strategy to help you remember meaningful information. The idea behind the strategy is that relevant prior knowledge is not always readily activated when you are trying to learn new information, and sometimes help is needed to make the right connections. The strategy requires you to go beyond the information given to you and to construct reasons for the relationships between bits of information.
In general, the weight of the research evidence suggests that college students tend to have a poor sense of how prepared they are for testing, and having been tested, they have a poor sense of how well they did! (This, of course, is even more true of younger students).
Does it matter?
The story method (sometimes called the sentence mnemonic) is the most easily learned list-mnemonic strategy, although it is not as widely known as the other simple methods we’ve talked about so far.
As its name suggests, the story method involves linking words to be learned in a story. While this is most obviously useful for learning actual lists, it can also be used for remembering the main points of a passage. In such a case, you need to reduce each point to a single word, which hopefully has the power to recall the whole point.
I’ve discussed on a number of occasions the effects that stereotypes can have on our cognitive performance. Women, when subtly reminded that females are supposedly worse at math, do more poorly on math tests; African-Americans, when subtly reminded of racial stereotypes, perform more poorly on academic tests. And beliefs about the effect of aging similarly affect memory and cognition in older adults.
Back in 2010, I read a charming article in the New York Times about a bunch of neuroscientists bravely disentangling themselves from their technology (email, cellphones, laptops, …) and going into the wilderness (rafting down the San Juan River) in order to get a better understanding of how heavy use of digital technology might change the way we think, and whether we can reverse the problem by immersing ourselves in nature.
To use note-taking effectively, you need to understand that its primary value is not in the record you produce, it is in the process itself. The process of taking notes guides the memory codes you make. Note-taking is a strategy for making information meaningful. It is therefore only effective to the extent that you paraphrase, organize and make sense of the information while taking notes.
