Technology is a core part of IB Maths AI, so it feels logical to rely on calculators and software as much as possible. Many students assume that because technology is allowed — and even encouraged — using it extensively must be rewarded. In practice, over-reliance on technology often leads to lost marks.
The key issue is that technology can perform calculations, but it cannot demonstrate understanding. IB Maths AI is not assessing whether students can press the right buttons. It is assessing whether students understand what the output means and whether it is reasonable in context.
Students often lose marks by copying calculator results without explanation. A regression equation, probability value, or z-score produced by a calculator is not an answer on its own. IB examiners expect interpretation, justification, and evaluation. When these are missing, marks disappear even if the output is correct.
Another common problem is blind trust. Calculators always produce a result, even when the input or model is inappropriate. Students who fail to question whether a regression is suitable, whether normality is reasonable, or whether a probability makes sense demonstrate weak analytical judgement. IB penalises this because it contradicts the course’s emphasis on interpretation.
Technology also increases the risk of conceptual errors being hidden. A calculator can mask sign errors, incorrect regions, or invalid assumptions. Students who sketch graphs, estimate first, or reason before calculating are far more likely to catch mistakes than those who go straight to the screen.
IB is especially critical when technology replaces reasoning. For example, using a calculator to find a value without explaining why that value answers the question shows dependence, not understanding. Examiners reward students who use technology strategically, not automatically.
Importantly, IB does not discourage technology. It discourages uncritical use. Strong answers often combine calculator output with sketches, explanations, and limitations. This shows control rather than reliance.
Once students treat technology as a support tool instead of a decision-maker, their answers improve. Calculations become cleaner, explanations stronger, and marks more consistent.
In IB Maths AI, technology is allowed — but thinking must come first.
Frequently Asked Questions
Is using a calculator bad in IB Maths AI?
No. It’s expected — but it must be paired with explanation and reasoning.
When does calculator use cost marks?
When results are copied without interpretation or used without checking assumptions.
How can I use technology correctly?
Estimate first, calculate second, and always explain what the output means.
RevisionDojo Call to Action
Technology should support thinking, not replace it. RevisionDojo is the best platform for IB Maths AI because it trains students to use calculators intelligently, interpret outputs clearly, and avoid over-reliance that costs marks. If calculator-heavy answers aren’t earning full credit, RevisionDojo helps you rebalance calculation and reasoning the IB way.
