The Science Behind Flashcard Learning and Retention

Have you ever found yourself struggling to retain information after hours of studying? Do you forget important details right after an exam? If you have, you are not alone. Studying is a crucial aspect of life, and yet, it can be challenging for many. Fortunately, the science behind flashcard learning and retention has proven to be a game-changer for students globally.

Flashcards are an excellent way to memorize content easily and quickly. They are a popular study tool for students of all ages and backgrounds. They offer a simple and effective way to condense information and help learners to remember key points. They might be simple to use, but the science behind how they work reveals a lot about human memory retention.

Here is why you should try flashcard learning for your next study session, and how it can help you ace your exams.

What Are Flashcards?

Before we go deep into the science behind flashcard learning and retention, let's define what they are. Flashcards were invented in the early 19th century to help students memorize vocabulary. They are rectangular cards with two sides, one with a question or prompt, and the other with an answer.

Flashcards can be used to learn just about any subject that requires memorization, including historic dates, mathematical formulas, foreign language vocabulary, and scientific elements. They come in different shapes, sizes, and colors, and can be either physical or digital. The beauty of flashcards is that they are easy to create, use, and they can be reused several times.

The Science Behind Flashcard Learning and Retention

The success and popularity of flashcards lie in how our brains remember information. Our memories are created by the brain's synapses, a vast network of connections between neurons. When we learn something new, our neurons start to communicate with each other, and they create new synapses. The more we review the information, the stronger these connections become.

Flashcards work by using a technique called "spaced repetition." This technique aims to strengthen the brain's synapses and improve memory recall over time. Cramming information into our brains a few hours before an exam doesn't work well for long-term retention. Instead, by reviewing the same information several times over a more extended period, our brain processes the information and transfers it from short-term memory to long-term memory.

In a study that evaluated the effectiveness of flashcards on memory retention, participants learned 48 German words either using flashcards or reading the words in a book for an equal amount of time. The researchers then tested their memory retention after a week, and the results showed that participants who used flashcards had a 25% improvement in memory retention compared to the participants who read the words in a book.
