Grammar test post-mortem: which error gets whole-class time?
Thirty-eight students sat a 10-mark "Do as directed" grammar test built from the Class X syllabus: five plural items using the suffix -rang, three items on attaching the object particle -ko, and two on word order. The results are uneven. Twenty-six students formed plurals correctly. Nineteen wrote the particle as a separate word (mande ko rather than mandeko). Twenty-four put the verb in the middle of the sentence, apparently translating English order word for word. Twelve dropped the raised dot in A·chik, including four students who wrote it correctly in the passage question. Your grammar notes describe Garo as a verb-final language and list -ko as a bound suffix written onto the noun. You have two periods before the annual exam, and the Head has asked you not to re-teach the whole unit.
1. Decide which errors get whole-class time, which get small-group time, and which get a reminder. Give numbers and a reason.

Whole class, 20 minutes: word order (24/38 = 63% wrong). It is the only error that damages every sentence a student writes, including answers in the literature section, so it has the widest transfer. Whole class, 5 minutes: particle attachment (19/38). It is a mechanical fix with a fast check, but it cannot be left to a small group because half the class has it. Small group, 10 minutes: plural -rang (12 wrong). These students need the rule, not more exposure; the 26 who are secure can start a longer writing task. Reminder, 3 minutes: the raised dot (12 students). It is one spelling feature and four of those students already use it correctly elsewhere, which suggests carelessness under time pressure rather than ignorance. Do not spend a whole period on it.
2. Write the board explanation you would use for verb-final order, with one correct example, one non-example, and one quick check.

Board:
- Write the English sentence "I eat rice" on the left. Ask: which word is the action?
- Build the Garo column beside it and move the action to the end: Anga mi cha·a (I + rice + eat). Underline the last word twice.
- Non-example: write "Anga cha·a mi" and put a cross beside it. Say: "This is English order with Garo words. The verb has jumped the queue."
- Rule on the board: the verb comes last; everything else comes before it.
Quick check (60 seconds): give three English sentences on slips - "The boy reads a book", "We go to school", "She cooks rice" - and ask students to write only the last word of the Garo version, then the whole sentence for one of them. Collect two slips.
Do not teach this with six examples. Two clear contrasts and one check beat a board full of sentences students copy without thinking.
3. A student drops the dot in A·chik in the grammar section but writes it correctly in a literature answer. What is your marking policy?
Read the worked answer
Set a consistent policy and state it to the class before the exam:
- The dot is not decoration. It marks a distinct sound in the standard spelling and distinguishes written forms, so within a spelling or grammar item the omission is an error and the mark is not given.
- Do not deduct in a literature answer where the student is being assessed on content and argument. Deducting twice for the same slip punishes the student for the examiner's thoroughness.
- Do not deduct in every item either. If the same slip appears three times in one grammar section, deduct once at the item where the word is the target and note it in the margin.
Comment: "You wrote A·chik correctly in question 7, so this is a checking problem, not a knowledge problem. In the exam, circle every A·chik and check the dot before you hand in." The policy is defensible because it separates spelling assessment from content assessment.
