Reported Speech Doesn't Shift Tense in Korean, and Neither Do Your Students
Korean reported speech quotes the original sentence without changing its tense, so students carry that habit straight into English and say "She told me she is tired" instead of "she was tired."

Ask a middle schooler to report what a friend said, and you'll almost always get the present tense sitting where a past tense should be. "He said he is busy." "My mom told me she doesn't like it." It sounds like a small slip. It isn't. It's a structural habit borrowed from Korean, and it doesn't fix itself just because a student "knows" past tense.
Why it happens
Korean reported speech runs on a quotative particle, usually -다고 attached to the verb, and it quotes the original sentence more or less as spoken. If your friend said "나는 바빠" (I'm busy), you report it as "바쁘다고 했어" — the tense marker on 바쁘다 doesn't shift just because you're now speaking about it later. Korean tense is anchored to the moment of the original utterance, not to the moment you're reporting it.
English works differently. When the reporting verb (said, told, thought) is in the past, the embedded clause usually backshifts too: is → was, will → would, has done → had done. This is called sequence of tense, and it's one of those rules nobody explains out loud because native speakers do it without thinking. Korean students transfer their L1 pattern and keep the original tense, because in their heads, that's the accurate report of what was actually said.
So the error isn't laziness or forgetting a rule. It's a direct, sentence-by-sentence translation of a grammatical structure that is completely correct — in Korean.
Common transfer errors
| Korean structure (literal sense) | What students write | What a native speaker says |
|---|---|---|
| 바쁘다고 했어 (said: "I am busy") | He said he is busy | He said he was busy |
| 갈 거라고 했어 (said: "I will go") | She said she will go | She said she would go |
| 모른다고 했어 (said: "I don't know") | He said he doesn't know | He said he didn't know |
| 끝났다고 했어 (said: "it's finished") | They said it is finished | They said it was finished |
Drills that actually target this
- Same-day reporting drill. Have a student make a true statement about themselves ("I'm hungry," "I like pizza"). Wait five seconds. Have another student report it: "___ said ___." Force the backshift every time, out loud, before moving to the next pair.
- Timeline correction. Give ten sentences with the error (present tense inside past reporting) and have students correct only the embedded verb — not the whole sentence. This isolates the exact spot the mistake lives in.
- Exception check. Point out the one place backshift doesn't apply: general truths and facts that are still true now. "The teacher said water boils at 100 degrees" stays present tense. This exception trips students up once they've finally learned the rule, so flag it on purpose rather than let them discover it as a "mistake."
- Speaking chain. Six students in a circle. Each reports what the last person just said, past tense, no notes. By the fourth or fifth round the group usually catches its own errors faster than you can.
We'll be honest about one thing: how strictly to enforce backshift with will/would trips up even fluent English speakers in casual speech, and Korean textbooks vary on whether they even introduce "would" as the reported form of "will" before high school. If a student's textbook hasn't covered it yet, don't correct it out of context — check what they've actually been taught before drilling an exception they haven't met.
