There are many ways to think about the process of language learning. For the purpose of planning personal study time, it can be helpful to think about language learning in terms of three interconnected components.
To design an effective personal study plan, you will want to give explicit attention to each of these three components. There are a variety of techniques you can use to build skills within each component. Try out the techniques and see which work best for you now and try out new ones as your language skills progress.
As you experiment with these techniques, you will see that many effective language study techniques emphasize one component (memory, comprehension and understanding, or communication), but incorporate activities that also contribute to developing skills in the other components at the same time.
In very simplistic terms, all that linguistic and cultural information is stored in many different locations in your brain. As you encounter, store and retrieve that information in multiple ways, you create and strengthen the links in your brain among all those various bits of information. This process is literally making physical changes in your brain. The more information you store and the more robust the pathways that allow you to retrieve and use that information in linguistically and culturally appropriate ways, the higher your level of proficiency in the language.
It is not uncommon for language learners to learn a lot about a language or to comprehend the language, but not be able to communicate in the language. This happens when students store many bits of information, but do not practice using the language for communication:
In this way, learning a language is more like learning to play a musical instrument, dedicated athletic training, or training in theater or dance. It is not about just doing some grammar exercises and memorizing individual vocabulary words, rather you need to engage in the activity of communicating over and over again, honing your skills, in order to develop the ability to use the language at a high level of proficiency.
