How Can Teachers Check Grammar and Subject Terms in Large Classes?

Published on 23 October 2026

In large classes, teachers can check spelling, grammar and subject vocabulary by separating these checks from content marking, deciding in advance how many marks each is worth, and using a shared list of key terms for every chapter. Mark language and vocabulary with a quick, consistent routine, then spend your real attention on ideas and understanding. A tool can take the repetitive checking off your hands, as long as you keep the final marks.

Why is language checking so time-consuming?

With forty or more students in a section, correcting every spelling and grammar error by hand quickly takes over your evenings. It is also inconsistent. By the thirtieth notebook, it is hard to circle errors with the same care as the first, and students notice when one classmate loses marks for a mistake another did not.

Language checking also crowds out content. If you spend your energy underlining errors, there is less left for asking whether the student actually understood photosynthesis or the causes of a historical event.

How should I divide marks between content and language?

Decide before you mark, and tell students. A simple split for a long answer in science or social science might be:

• Content and understanding: most of the marks.
• Use of subject terms: a few marks for using key words correctly.
• Presentation and language: a small share for spelling, grammar and clear sentences.

In an English writing task, language naturally carries more weight. The important thing is that the split is written down, so the same error costs the same marks for everyone.

How do I check subject vocabulary quickly?

Make a list of key terms for each chapter. For a lesson on the water cycle it might include evaporation, condensation, precipitation and transpiration. Then, while reading an answer, simply check:

• Which key terms did the student use?
• Did they use them correctly, not just mention them?
• Which essential terms are missing?

Sharing the list with students before they write helps them too. It tells them what a complete answer looks like, which is especially useful as students prepare for board examinations, where precise subject terms matter.

How can I give spelling and grammar feedback students will use?

Circling every mistake rarely changes anything. More useful approaches:

• Group errors by type. If a student repeatedly confuses its and it's, one note with three examples is clearer than three separate circles.
• Ask students to keep a personal list of words they often misspell and correct them in their next piece.
• Give a short whole-class lesson on the three most common errors you saw.
• Return a table of errors with corrections, so students can practise from it.

How do percentages and rubrics fit together?

Percentages are a familiar way to report marks in Indian schools. A rubric translates easily: total marks earned divided by total available. Keep the conversion visible to students, and keep your judgement in the loop. If an answer shows clear understanding in imperfect English, your rubric and your final mark should reflect that.

Can AI do the routine checking?

Yes, and this is where it is most useful. Korektor is a web app that grades written work against the rubric you set. Alongside a percentage and comments on each criterion, it produces a spelling and punctuation table and lists the subject terms a student used and the ones that are missing. Spelling is checked against English norms, and you can review and change every mark.

How do I check a class set of answers with Korektor?

1. Create an assignment from a template (science report, composition or argumentative essay) or from scratch, with the question, word range and deadline.
2. Add your rubric criteria with marks, for example content, subject terms and language, weighted the way you want.
3. Select what the AI checks: spelling and punctuation, subject vocabulary, comments on the text and, if useful, sources and images or drawings. Add your key-term list to the free-text instructions for the grader.
4. Choose strictness and feedback tone, and decide whether students see their marks.
5. Share the link. Students type their name, need no account, and upload photos of their notebook pages (up to 8), a Word file, PDF, PowerPoint or plain text, or paste their answer.
6. Each answer is graded in about 20 to 60 seconds. Open "received papers", check the vocabulary and spelling tables, and adjust any percentage you disagree with.

What does it cost, and where is the data kept?

The first 3 gradings are free without an account, and a free account adds 3 more. After that, packs cost 5 euros for 30 gradings, 14 euros for 100 or 36 euros for 300, and they do not expire. Student work is stored on Cloudflare in the European Union, with no advertising and no selling of data.

Where should I begin?

Start with one chapter. Write the key-term list, decide your mark split, and share both with students. Then run that chapter's answers through Korektor and compare its vocabulary and spelling tables with what you would have marked by hand.
