“Doesn’t know the word” and “score isn’t improving” are not the same problem
A child can ace a vocabulary quiz and still lose the meaning of that same word once it appears in a passage. That gap is common: knowing a word in isolation and judging its meaning inside a sentence are genuinely different skills.
So when a score stalls, reaching straight for more vocabulary lists skips the diagnosis step, and can end up being the long way round.
What else commonly costs points
In actual lessons, several causes show up more often than a plain vocabulary gap.
- Shaky grammar, which throws off the meaning of the sentence structure itself
- Reading each sentence fine, but losing track of the passage as a whole: who did what
- Reading too slowly to finish within the time limit
- Hearing the sounds fine in listening, but taking too long to convert them into meaning
- Knowing what a word means, but stalling when trying to use it in writing
- Getting stuck at the stage of forming an opinion or a reason, before English even enters the picture
- Not being familiar enough with the question format to know exactly what is being asked
A simple way to tell the difference at home
When reviewing a wrong answer, going a little further than “she didn’t know the word” tends to reveal the actual cause.
- Did she not know the word at all, or did she know it but still miss the meaning of the sentence?
- Did she run out of time, or would she have missed it even with time to spare?
- Is the same type of mistake repeating, or is each mistake caused by something different?
A repeating pattern of the same mistake more often points to grammar or a reading habit than to vocabulary.
When vocabulary really is the problem
Vocabulary is often the real cause too. It deserves priority when:
- The student does not know common words at the grade's level
- A word looks familiar but its meaning in context is vague
- They recognise it when reading but cannot recall it to write or speak
- They know each word but cannot parse the sentence
- They know the meaning but not the usual word combinations or contexts
A vocabulary diagnosis matrix
| Student behaviour | Possible issue | Test it by | Next practice |
|---|---|---|---|
| Misses words even on a word test | Not enough vocabulary | Ask for meanings | Learn frequent words with example sentences |
| Word looks familiar, meaning vague | Weak retention | Meaning without options | Recall practice without the list |
| Cannot read the same word in a passage | Meaning in context | Give a sentence containing it | Guess meaning from context |
| Words do not come when writing | Recall and use | Japanese to English prompt | Build short sentences from examples |
| Knows words but sentence will not connect | Sentence structure | Mark subject and verb | Review grammar and sentence patterns |
| Meaning right, usage unnatural | Collocation and context | Ask for an example sentence | Learn common word partners with examples |
“Knowing” a word has stages
It helps to ask where a word stops: recognised, understood in context, recalled when needed, used correctly. Schmitt's (2008) review notes that many aspects of each word have to be learned and that vocabulary learning is incremental. The four stages here are not an established scientific ladder; they are a practical way of observing learning. Reading and listening lean on the first stages; writing and speaking need recall and correct use. The Education Endowment Foundation's secondary literacy guidance likewise recommends teaching vocabulary deliberately.
If you change how words are learned, start with methods that have evidence
Even when vocabulary is the cause, going over Japanese translations again and again may build quiz performance without transferring to using the word in a sentence. These four approaches are among the better supported in learning research.
| Approach | In practice | Evidence |
|---|---|---|
| Recall rather than re-read | Before looking at the list again, say or write the meaning from memory. Mark the words you could not recall | The review by Dunlosky and colleagues (2013) rates practice testing as high-utility and rereading as low-utility |
| Space it out rather than cramming | Recall the same words again on different days | The same review also rates distributed practice highly, and the synthesis by Cepeda and colleagues (2006) finds spaced study is better remembered. The best gap depends on how long you need to remember |
| Learn use, not only meaning | Check a short example sentence, common word partners and the situations where the word is used | Schmitt (2008) notes that many aspects of each word must be learned and that vocabulary learning is incremental |
| Increase exposure too | Add reading and listening where the same words recur, alongside deliberate practice | Schmitt argues for both intentional learning and more exposure. The meta-analysis by Uchihara and colleagues (2019) found a medium link (r = .34) between the number of encounters and incidental vocabulary learning, smaller for primary and secondary students than for university students |
Most of this research involves university students or adults and did not test EIKEN vocabulary questions directly. After changing the method, check again in one to two weeks, using the matrix above, whether more words are understood in context and used in writing. Full citations are in the references below.
A one-week review example
One way to apply recall, spacing and learning use over a week. The best number of days is not settled in the research, so adjust it to the student.
| Day | Do | Tip |
|---|---|---|
| Day 1 | Learn the word and write one sentence | Learn the context, not only the meaning |
| Day 2 | Recall meanings without the list | Mark the ones missed |
| Day 4 | Use it in a new sentence | Change the subject or setting |
| Day 7 | Mixed review with other words | Missed words go back to Day 1 |

If words do not appear when writing, see why EIKEN writing stalls. To sort errors by cause, see what to fix after a low past-paper score, and for the final week, the week before the first stage. Tutors who support EIKEN include Hannah, Haruka and Nikko; see the EIKEN page for the overall service.
What Petra Tutors checks before starting EIKEN preparation
At Petra Tutors, before starting EIKEN preparation we first map out where points are actually being lost (vocabulary, grammar, reading, listening or writing) and set priorities from there.
Sometimes more vocabulary genuinely is what is needed. When it is not moving the score on its own, we look instead at how a student reads and applies grammar.
