IBDP MathsIA CriterionB

Criterion B is...

• Mathematical presentation

• Organisation

• Communication

• Personal engagement

Not part of Criterion B

• Notations and symbols

• Key terms and mathematical representations

• Terminology and variables

• Inductive reasoning and mathematical language

How can this be fixed?

How can the notation be fixed?

What could help?

• E.g. 'height' near number -2 and 'length' near number 3

• E.g. 'height' near the red curve and 'x' near number 3

• E.g. 'x' near number '2 and 'length' near the red curve

• E.g. 'x' near number -2 and 'y' near number 3

Why is a definition expected here?

• The moderator isn't very bright/informed.

• It's a key term, plus the word doesn't exist in your syllabus.

• The full report might be too short; definitions can help add words.

• A 'Definitions' section is always required.

How should the examiner's first concern ('what this is the probability of') be addressed?

• change the subject of the equation to 'P'

• change the subject of the equation to 'P(binomial)'

• change the subject of the equation to 'P(x)'

• change the subject of the equation to 'P(k)'

What's the issue here?

• Only one mathematical representation

• The notations are written incorrectly

• The variables are not defined

• 'Home game' is too informal
