Language learners improve their writing and comprehension skills when they keep a journal. The learner should write in their chosen language, even if they are simple sentences. In time, the learner benefits from journal-keeping by being more aware of their own learning process. It also motivates the learner to set benchmarks for themselves to write a better entry every time. These journals help the learner learn vocabulary and grammar skills as they are able to express themselves.
The need to convey their feelings forces them to learn words and phrases in the language that best impart what they mean to say. It is an established fact that writing also helps memory retention. So learners will be able to memorize these lessons quicker. Writing in a personal journal is just the same as speaking it. It is impossible to write without speaking the words first in the head. In this way, it is a comprehensive practical learning experience.
