You replay today a passage you listened to yesterday. Before you do, try recalling in a single phrase what it was about. If you want to add something to your review, you can start with a question this small rather than a big test.
That said, research does not directly prove that "recalling the next day improves listening." Let's keep what the research has confirmed separate from the ideas we bring into everyday audio practice.
What the research compared was foreign-language vocabulary learning
In a 2008 study by Karpicke and Roediger, using foreign-language vocabulary as material, conditions such as continuing to study items after they had been answered correctly, or continuing to test them, were compared. The abstract reports that repeated testing after correct answers benefited delayed recall. Original abstract: The critical importance of retrieval for learning
Retrieval here means pulling something out of memory without looking at the answer. Distinguishing between "I understood it when I looked again" and "I retrieved it without looking" is a useful perspective when designing review.
On the other hand, this study alone does not allow conclusions about podcast comprehension, pronunciation, distinguishing sounds, or the effectiveness of any particular app. Nor does it show that "the next day," as proposed in this article, is the optimal interval for everyone.
Applying it to a passage of audio
From here on, this is a practical suggestion from the editorial team. Use a short passage whose content you checked the previous day, and before playing it, write one line in your own language about "who decided what." You don't need to make it a task of reciting the whole English text from memory.
For example, consider a passage we made up as sample content: "Because rain was forecast, the outdoor gathering was moved to the library." The next day's question: "What was the reason for changing the location?" After writing your answer, check it against the audio and a reliable transcript.
If you wrote "because of rain," that's a record that you recalled the reason. If you wrote only "the library," the location stuck, but the reason still needs checking. Neither is evidence that you caught the fine details of the sound. The key to this approach is not to score remembering the content and catching the words by ear as if they were the same thing.
Separate columns for before and after seeing the answer
On a sheet of paper, prepare just three lines.
- Before playing: I think the reason for the location change was rain.
- After checking: The reason was right. Where it moved to was vague.
- Part to listen to next: The sentence announcing the new location.
This is a sample entry, not an actual learning record. Rather than finely grading "I sort of remembered," keeping your pre-check answer without erasing it shows you what to go back to. If you rewrite your answer after reading the transcript, move it to the after-checking line.
So that you don't feel you heard something just because you remembered the content, finish by checking with the audio alone. If needed, you could split the recall task and the listening task onto different days. That's a choice to avoid cramming too many tasks into a short review.
On days nothing comes, make the question smaller
If you can't recall anything, you don't need to make struggling with it for a long time today's goal. First play the audio and check the content, then leave just one question for next time: "Where was it moved to?" There's no need to memorize a guess made while unsure as the correct answer.
Conversely, just because you answered right away doesn't mean you have to add more questions. Today's purpose is to change one thing about how you begin your review. Answer a short question before opening the audio, check it, and finish. First, see whether that flow fits into your practice.
It doesn't have to be the next day; the next day you're able to work on it is fine too. Leaving review intervals and amounts as a separate question, this time let's focus on leaving "one line before opening the answer."
