19. 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.
