It doesn’t matter which kind of learning style works best for you, it is indispensable to write as much as possible.
You may prefer watching or listening to content. You may prefer reading or even just converse with native speakers for a more “hands-on” approach.
Yet, to make sure your studies actually progress steadily, you absolutely need to write as much as possible the information you wish to retain.
Unfortunately for us, while the society’s advancements along the years have made it strikingly easy to get access to a phone or computer and write on those, the information retained through such practice does not allow for memories to actually form well in our brains.
The action of writing down on a piece of paper takes a lot more time and as such, our brains get the amount needed to think about the points themselves further.
This allows them to cement farther and thus recall them better in the long-term.
Spending the extra time to write down examples, thinking of new sentences to write using the newly learned content are great ways to consolidate knowledge.
Nowadays, with the use of numerous apps, most language learners simply read, choose the right answers on an app and even type on their smartphone. Yet, while a great way to keep learning on the go, such activities get processed too quickly to allow you to remember them quickly.
Apps such as Anki and other Spaced-Repetition Systems (SRS) are a way to overcome this problem as words/expressions will appear again at the right time to consolidate the knowledge learned, but the monotony of it and the lack of real long thought-process happening makes it less time-efficient.
Writing down by hand takes more time but the advantages stated above can be refuted by simply saying words copied do not allow us to actually think carefully about them.
This is when pure writing, as in the sense of “creation” comes into play. Writing your own examples, a small paragraph, a sum-up of something you read or saw will push your brain to make the association with the newly learned pattern but also give the time to carefully let the connections appear within your brain.
Obviously, as a language learner, you will always make some mistakes so it can be of interest to also post long sentences or paragraphs to platforms online to get corrections from native.
You can thus transfer the corrections made by them to your notebook, which allows you to consolidate the knowledge in a shorter span of time.
If you wish to learn a language well, for the long run, get a notebook and make use of it as much as possible. I can attest that if you don’t you might get stuck like I was for years for Chinese.
