What I have done is listen to a foreign language audiobook while having the text in English, which I find extraordinarily helpful at an intermediate level where you understand most of the words but may not catch the full meaning.
disagree. from what i experience, some of the most helpful parts of reading are when you stop and take a minute to ponder the words, or write it in the side column. Thats the main downside to audiobooks imo, you dont have time to stop and think. That applies whether you just use audiobook or audiobook + reading text, but not in the caze of just reading.
One thing what helps a lot is .. turning the subtitles off. Or just make the video run at the background, where you can occasionally glimpse it, but it's not your primary activity.
It’s the same when watching foreign TV. Having subtitles on in the same language that is spoken is really useful, you learn more than only reading or only listening.
The key to learning is comprehensible input. You want to understand 98% of what you're reading. You can get that through repeatedly reading the same things, through graded readers, and through the use of bilingual dictionaries. Once you get to the point when you can make a switch to interesting arbitrary target language reading using only a target language dictionary, it becomes a virtuous circle and simply a matter of time.
If the orthography of a language is weird, I could see this being useful to get to the next step, but as far as I know Polish orthography is straightforward (unlike English, French, or Chinese for example.)
edit: on second thought, it might help with acquiring the prosody of Polish even if you're just listening (and hopefully reading along out loud) to the sounds like a dog would. Prosody is half the battle.
edit2: also translations are a pretty bad idea. You're trying to pick up the prosody of Polish, but you're reading people trying to imitate English in Polish. Unless it's a very free translation to the point that it distorts the original work. Just find out what Polish people are doing; their cultural references are part of the language anyway.
> To translate, you'll rely on your existing knowledge, quick look-ups, context clues, and the audiobook's narration (inflection, pacing, etc.).
