From my experiance in relating with teachers, many Nigerian teachers today are already familiar with ChatGPT. In fact, among educators, ChatGPT is the most widely embraced AI model compared to others like Grok, Deepseek, Perplexity, Claude, or LLaMA. Some of us are even curious about Google’s Gemini AI because of its new Nano Banana image generation feature.
But here’s the truth: while teachers are using ChatGPT to draft lesson notes, create exam questions, or brainstorm classroom activities, most are missing out on hidden features that can make their teaching easier, their lesson delivery sharper, and their students more engaged.
That’s why I, Oluwole Oyebajo, created this guide — to show you four overlooked ChatGPT features every Nigerian teacher should master. Think of these tools as small hinges that swing big doors of productivity in your teaching career.
Problem: Teachers often complain: “ChatGPT’s answers are too general, sometimes too advanced for my pupils, or too simplified for my SS3 students.”
Agitation: Imagine spending time rewriting or reshaping AI-generated notes over and over, just to fit your class level. That’s extra stress you don’t need.
Solution: With Custom Instructions, you can make ChatGPT respond the way you want, every time. In Settings > Personalisation > Custom Instructions, you can tell ChatGPT:
What it should know about you (e.g., “I teach Primary 4 and SS1 in Lagos and Oyo States”).
How you want it to respond (e.g., “Always explain in simple, child-friendly language for junior classes” or “Provide exam-focused notes for senior classes”).
This way, if you’re teaching “Photosynthesis” in JS2, ChatGPT can automatically generate an engaging activity like a “leaf observation experiment” for juniors, while giving detailed chemical equations for SS3 — without you repeating instructions.
Problem: Many of us rely on textbooks and sometimes outdated internet articles to prepare lessons. But education keeps changing. Students often ask questions about current affairs, science updates, or even global events that our textbooks don’t cover.
Agitation: Picture standing in class, a student asks, “Sir, what’s the latest about space exploration?” or “Madam, why did WHO recently change its malaria guidelines?” You pause, unsure — because your materials are old. That gap reduces your authority.
Solution: With Deep Research (web browsing), ChatGPT can now pull in real-time, up-to-date information with citations. For example:
You can get the latest WAEC news and syllabus updates.
A Civic Education teacher can fact-check the newest Nigerian constitutional amendments.
A Basic Science teacher can pull global updates on climate change to enrich lessons.
Instead of jumping between Google, multiple articles, and personal notes, ChatGPT organizes the findings for you. It’s like having a research assistant in your pocket.
Problem: Teachers juggle a lot: lesson notes, marking scripts, PTA meetings, assembly duties, and personal errands. It’s easy to forget things.
Agitation: Have you ever remembered — too late — that you were supposed to prepare an assembly talk, send continuous assessment results, or remind your class to bring materials for a science project? That moment of panic is stressful.
Solution: ChatGPT now has Tasks, Reminders, and Memory features.
You can tell it: “Remind me to prepare lesson notes on Vertebrates by Friday” — and it does.
With Memory, ChatGPT remembers your teaching levels, ongoing projects, or even your favorite way of formatting lesson notes. You don’t need to reintroduce yourself in every chat.
Imagine ChatGPT saying: “Mr. Oluwole, last week you asked me to create lesson plans on Plant Reproduction. Do you want me to continue with Pollination for this week?” That’s not a chatbot — that’s a real assistant.
Problem: Typing can feel slow, especially if you’re rushing to prepare for a class or want quick feedback while marking scripts.
Agitation: Think about those times you’re cooking dinner, or supervising your children at home, and an idea for tomorrow’s lesson pops up. You sigh because typing feels like work.
Solution: With Voice Mode, you can just speak to ChatGPT — and it responds out loud. For teachers who learn or think better by talking, this is a game-changer.
Even more powerful is Image Input. Snap a photo of a math problem, a diagram in your textbook, or even a badly scanned exam question. ChatGPT can analyze it, explain it, or recreate it neatly for you.
For example:
A Yoruba teacher can take a photo of a folk tale text and ask ChatGPT to summarize it.
A Chemistry teacher can upload a reaction equation and ask for a step-by-step breakdown.
A Home Economics teacher can upload a food timetable and ask ChatGPT to suggest a healthier version for students.
Teachers, the future of education is not about replacing us with AI — it’s about empowering us with AI. Tools like ChatGPT are not here to make us lazy; they’re here to make us smarter, more efficient, and more impactful in the classroom.
If you’ve only been using ChatGPT for lesson notes or exam questions, you’ve been scratching the surface. With Custom Instructions, Deep Research, Tasks & Memory, and Voice & Image Mode, you can elevate your teaching game far above average.
