How to Generate Great Questions

The fastest question generator is six words: WHAT, WHO, WHERE, WHEN, WHY, HOW. Watch them work on a single textbook sentence — 'Photosynthesis is the process by which plants convert light energy into chemical energy.' WHAT is it, and which words are new to me? WHO does it — all plants? algae? bacteria? WHERE in the plant, in which structures? WHEN — only in daylight? WHY convert light into chemical energy at all, rather than using light directly? HOW, exactly — what are the steps? From one sentence you've produced five terms to define, a dozen questions, and three genuine gaps you didn't know you had. That's active reading: you're not highlighting, you're extracting structure.

When you need questions on demand, use the QUESTION FORMULATION TECHNIQUE. Start from a provocative STATEMENT rather than a question — something like 'Plants can survive without soil.' Then five steps. GENERATE (8–10 min): write as many questions as you can, and critically, do not judge, discuss or answer any of them — that no-judging rule silences the inner critic that normally stops you asking 'basic' questions. CATEGORISE: mark each Open (needs explanation) or Closed (yes/no). TRANSFORM: convert closed ones to open and vice versa — you need both. PRIORITISE: pick your top three by deepest learning, biggest confusion and genuine curiosity. USE THEM: take them to your teacher or study group, and read specifically to answer them.

Once you have twenty questions, three of them are worth your session. Order them FOUNDATION → MECHANISM → APPLICATION. Priority one is the foundational question everything else depends on: 'What is the minimum a plant needs to survive?' Priority two asks HOW, building on that foundation: 'How would it get nutrients without soil?' Priority three tests flexibility by applying it: 'How do soil-grown and hydroponic plants differ?' Choose using four criteria: which question leads to the deepest learning, which addresses your biggest actual confusion, which you're most genuinely curious about, and which would help you answer several of the others. That last criterion is the most useful — some questions unlock whole clusters.

Keep a set of question stems in your head and you'll never face a blank page. UNDERSTANDING: 'What is…?', 'How does… work?', 'What's the difference between… and…?' ANALYSIS: 'Why does…?', 'What causes…?', 'What's the underlying principle of…?' APPLICATION: 'How could I use…?', 'What's an example of…?' EVALUATION: 'Is… effective?', 'What are the strengths and weaknesses?' SYNTHESIS: 'How does… connect to…?', 'What if we combined… and…?' Then add subject flavours — science asks 'what's the mechanism?' and 'what evidence supports this?'; maths asks 'why does this method work?' and 'what happens at the edge cases?'; history asks 'whose interests were served?'; English asks 'what context explains this choice?'

Three drills turn questioning into a habit. THE FIVE WHYS: pick a concept and ask 'why' five times in a row, each built on the previous answer — 'Why do plants need sunlight?' … 'Why photosynthesis?' … 'Why that specific process?' By question five you're into genuinely deep territory. THE QUESTION MARATHON: set a timer for five minutes and generate twenty or more questions on one topic; the speed removes your filter, and the 'silly' questions are often the insightful ones. THE EXPERT QUESTION: ask 'what would an expert ask about this that I'm not thinking to ask?' — then try to write that question yourself. And set a daily quota: at least five questions per study session — two or three before you start, two or three while learning, one or two in reflection.
