What drives English teachers most crazy?
Not disobedient students — weekend essay grading. Over 100 essays, each requiring line-by-line reading, grammar error identification, scoring, and personalized comments. A whole weekend spent buried in essays, with no personal life left.
Teacher Wang at a Shenzhen middle school collects 100+ student essays every week. This year, he tried deploying an essay grading Agent on Kaihe AIBOX. Essay grading became something that barely takes time.
How 2 Agents Divide the Work
Essay Grading Agent. Teacher Wang photographs or types student essays into WeChat. The Agent automatically completes three steps:
Correction — Identifies grammar errors, spelling mistakes, and inappropriate word choices. Not just marking errors, but providing correct expressions. For example, a student writes "I go to school yesterday" — the Agent corrects: "Tense error. Past tense should be 'I went to school yesterday.'"
Scoring — Based on Teacher Wang's configured scoring criteria (grammar accuracy, vocabulary richness, structure logic, content depth, language fluency), the Agent scores each dimension and gives a total score. Each essay includes a detailed dimension breakdown.
Comments — Auto-generates personalized feedback. Not generic templates: "Your tense usage is excellent, especially in past tense with barely any errors. Suggest strengthening vocabulary diversity — try using more advanced vocabulary." Each comment matches Teacher Wang's usual tone.
Daily Exercise Generator. Monday through Friday at 8 AM, the Agent generates 5 grammar exercises and pushes them to the class group. Exercise types: tense selection, error correction, cloze tests, Chinese-to-English translation, sentence ordering.
Questions auto-align with the week's teaching progress — if past perfect tense is being taught, exercises focus on past perfect. Difficulty adjusts dynamically based on overall class performance — if the previous week's essays showed concentrated errors on a specific grammar point, this week's exercises emphasize that area.
Teacher Wang reviews the exercises daily — 2 minutes to check, then one-click send to the parent group.
Results
Grading time from 3 days to 3 hours. Previously, 100+ essays took at least 3 days — collected Monday, finished Thursday, returned Friday. Now 100 essays with AI grading takes about 3 hours — Teacher Wang only reviews scoring accuracy and comment quality. Same-day collection, same-day results.
Parent satisfaction improved. Previously, essay scores had only a total grade and a brief comment — "Good work, keep it up." "Some grammar points need attention." Now each essay includes detailed error lists, 5-dimension scoring breakdown, and targeted comments. Parents see detailed grading reports in the group chat and feel more confident about teaching quality.
Class essay performance statistics. The Agent auto-compiles overall class performance — which grammar point had the highest error rate (tense errors 42% last week), who improved most, who needs focused attention. Teacher Wang adjusts next week's teaching priorities based on data.
Daily grammar exercises auto-generated. Previously generating exercises took Teacher Wang 30+ minutes per set — writing himself or copying from exercise books. Now the Agent generates daily exercises automatically. Teacher Wang checks for 2 minutes and sends them out. Saves dozens of hours of exercise prep time over a semester.
Why Not Existing Essay Grading Tools
Several AI essay grading tools exist (like "Pigai.net"). Teacher Wang tried one. The problem: no teacher control.
AI tools grade by platform-preset standards — you can't customize scoring dimensions, comment style, or error granularity. Teachers may want to grade by their own standards, but the platform doesn't support it.
The Agent approach lets teachers configure scoring criteria themselves. The Agent provides the framework (grammar, vocabulary, structure, content, fluency) — weights are set by the teacher. For example, vocabulary richness weight 30%, grammar accuracy 25%. Comment templates are also customizable — Teacher Wang prefers "positive first, then suggestion" format: "You did excellent in XX. Suggest strengthening XX." Comments follow this template.
Another issue: data security. Student essays contain personal information and performance data. Cloud-based essay grading platforms upload student data to their servers. The local Agent keeps all data on Teacher Wang's A1 device — student essay data never leaves the office, complying with teacher data protection requirements.
Essay grading isn't about AI replacing teachers — it's about AI handling the repetitive tasks of correction, scoring, and exercise generation. Teachers keep their time for more valuable work: analyzing student performance, adjusting teaching strategies, and communicating with parents. To learn more, visit the homepage.
