Nelson Mandela once said, "Education is the most powerful weapon which you can use to change the world." No one could ever argue otherwise, but how can you make education that much more powerful a weapon when in order to be powerful it must be easy to learn as well as be retained? The answer is by using visual aids.
Flashcards are not only one of the oldest types of visual aids, but they are one of the best because they are tried and true. Parents and educators have been using them for their children or learners, and the reason they do is that they work.
For one thing, flashcards help to introduce new vocabulary or drill familiar words; they have been used in such a capacity for centuries. By visually seeing a given vocabulary word, a learner automatically associates something visual to the word. Likewise, when reviewing vocabulary, a student or learner is able to recall a given word more quickly. Flashcards engage active recall, which is remembering a given piece of information from scratch, because they help create stronger connections to remembering the piece of information. If as a parent or teacher, your aim is to increase your child's or learners' active recall, you cannot surpass flashcards in this aspect. Active recall is the process of actively stimulating a learner's mind to recall or remember information learned.
Also, flashcards use mega cognitive skills because they enable learners to think and reflect about what they learn, for when a learner looks at a flashcard, they instantly remember what they had learned more rapidly, thus increasing their self-confidence. In fact, flashcards lend quite easily to confidence-based repetition when used for drilling, and it is through confidence-based repetition that learners' memory skills sharpen to a high degree, and not only do learners' memory skills sharpen, but their confidence likewise increases.
