• More real-life context• More formulation of situations prior to
solving• More communication

Trends in Assessment: Suggestions for Instruction
• Provide extended mathematical modelling experience once a term
which can be part of continual assessment
• Assess sub-skills of mathematical modelling in written examination
• A balanced approach that emphasised both formulating, solving and
interpreting.
