Taking the load off teachers: where AI really saves time
Short answer
AI saves teachers time above all in preparation: worksheets, exercises at different difficulty levels, summaries, quiz questions and explanations can be drafted quickly and then checked. It can also help with feedback on pupils' writing and with administrative texts. Assessments and decisions about pupils should stay with the teacher, though, and personal data belong only in systems approved for that purpose.
Key points
- Biggest benefit: drafts of material that the teacher then checks.
- Differentiation gets easier: the same task at several levels.
- Feedback on writing can be prepared, but not handed over.
- Grades and decisions remain the teacher's job.
- No pupil data in services that have not been approved.
Where teachers' time goes
Teaching is only part of a teacher's work. There is also preparation, marking, parent meetings, staff meetings, administration, cover lessons and, increasingly, tasks around digitalisation and inclusion. Many teachers report that the tasks outside the classroom in particular keep growing.
AI can ease some of this — not by replacing teachers but by providing drafts that a teacher checks, adapts and takes responsibility for. The gain lies in a faster start, not in handing over responsibility.
Where AI really helps
In some areas the benefit is clearly visible in practice.
| Task | What AI can contribute | What the teacher does |
|---|---|---|
| Lesson preparation | Drafts for openers, examples, board plans, lesson outlines | Select, adapt, tailor to the class |
| Practice material | Tasks, gap texts, quiz questions, flashcards from existing material | Check accuracy, adjust difficulty |
| Differentiation | The same task at several levels or in plain language | Assign appropriately to pupils |
| Feedback on writing | Suggestions on structure, language, argument | Check, add, phrase and own it |
| Admin and communication | Drafts for letters to parents, minutes, summaries | Check and send — without pupil data in third-party services |
Where caution is needed
Assessment is the most sensitive area. Grades have consequences for pupils and must be justifiable. AI can give pointers but can be wrong, miss patterns or disadvantage pupils with particular ways of expressing themselves. The AI Act classifies AI systems that evaluate learning outcomes as high-risk and requires, among other things, human oversight. Regardless of that, pedagogically: the teacher sets the grade.
A second risk is data. Pupils' work, names, grades and support needs belong only in systems the school has approved for that purpose. Pasting an essay with a name into a freely available chat program transfers personal data to a third party. Third: errors. AI-generated material can be factually wrong. Everything that goes into a lesson should be checked.
How to get started
The easiest entry point is material without pupil data: a worksheet on a topic, an exercise at three levels, quiz questions on a text. Here you can try out what works well without any data protection risk. Sharing experience among colleagues helps: Which requests produce good results? Where did much need fixing?
Anything that touches pupil data needs a system approved by the school. And for everything: the teacher checks and takes responsibility.
- Start with material that involves no personal data.
- Always check results for accuracy.
- Share good requests with colleagues.
- Pupil data only in approved systems.
- Do the assessing yourself; use AI for pointers at most.
What a platform can already do
In Universe — currently used at universities and in companies — several tools relieve teaching staff. The learning workshop creates a study guide, flashcards, quizzes, a mind map, an infographic, a podcast and a study plan from a course or one's own material. The course workshop turns presentations, PDF documents or texts into a course proposal with a speaking avatar. For written work, the platform suggests a grade with a report; the grade itself is always set by a person.
For schools, a dedicated offer is planned with Universe Classroom, in which the teacher keeps control over content and use; details are still being clarified.
Step by step
Pick an area
Start with a task that involves no pupil data, such as practice material.
Generate a draft
Have the AI produce a draft, stating subject, level and goal clearly.
Check and adapt
Check accuracy, level and fit for the class, and revise.
Share experience
Exchange good practice with colleagues.
Follow the rules
Pupil data only in approved systems; do the assessing yourself.
Frequently asked questions
May teachers use AI for lesson preparation?
For material without personal data, generally yes, unless state or school rules say otherwise. The teacher remains responsible for accuracy and suitability.
May AI mark class tests?
AI can provide pointers, but the teacher must carry out and take responsibility for the assessment. Systems that evaluate learning outcomes count as high-risk under the AI Act. Pupils' work may also only go into approved systems.
How much time does AI save?
It depends heavily on task, subject and experience. There are no reliable general figures. The gain is most noticeable with drafts of practice material and differentiation.
How can teachers spot AI-generated pupil work?
Not reliably; detection programs are unreliable. It is more effective to set tasks that make the thinking process visible — orally, in class, with intermediate steps.
Which AI rules should a school staff agree?
A few clear ones: which tools are approved, which data never go in, that all material is checked before use, that assessment stays with the teacher and how pupils disclose their own use of AI. Such rules should be agreed with school leadership and the data protection officer and reviewed regularly.
