Almost every English student has kept one. Two columns, English on the left, Turkish on the right, filled in neatly for a few weeks and then abandoned somewhere around November.
The method is not wrong. It is just incomplete in one specific way, and the fix is small.
Why the standard notebook fails
A two-column list is a record of words you have met. It is not a tool for practising them.
Open it and both columns are visible at once, so every word is answered before you can try to recall it. You read down the page feeling like you know everything, and that feeling is produced by the layout rather than by your memory.
Then there is order. Words sit in the sequence you met them, so you always review them in the same order, and you end up learning the sequence as much as the words. Ask for word fourteen out of context and it is gone.
And nothing ever leaves. Page one holds words you have known cold since September, getting the same attention as the word you learned yesterday.
The version that works
Keep the notebook. Change four things.
Cover a column. A folded page or a ruler is enough. The point is to attempt the word before you see it. Every look-up you replace with an attempt is where the learning happens.
Mark, do not erase. Put a small dot next to a word every time you get it wrong. After two weeks the dots have sorted your notebook for you: the words with three dots are your real homework, and the clean ones can be left alone.
Write the confusion, not just the word. If you keep mixing up quiet and quite, they belong on the same line, together, with a sentence for each. Written separately, they will stay tangled.
Add a date column. One narrow column on the right where you note when you last got the word right. It tells you what has not been touched for two weeks, which is exactly what needs testing.
What to write for each word
Less than most students write, and different.
The English word, the Turkish meaning, and one sentence you made up yourself. That is enough. A sentence about your own life gives the word something to attach to; a sentence copied from the book gives it nothing.
Skip the parts that feel productive and are not: colour coding, part-of-speech labels for every entry, three example sentences copied from a dictionary. They fill the page and the evening without asking anything of memory.
The honest limitation
Even a well-kept notebook cannot tell you the one thing that matters most: when to review each word.
The ideal moment to test a word is just before you would have forgotten it, and that moment is different for every word and drifts every time you practise. Tracking that across a few hundred words is not something a notebook can do, and not something anyone keeps up by hand.
Which is the honest case for doing part of this on a screen. A notebook is a good place to think about words. Something else has to remember which ones are slipping.
