Internal Assessment Criteria
Each piece of work is assessed against all six criteria. Criteria A, B, E and F are identical for both types of task. Criteria C and D are different for the two types of task.
Assessment Criteria for Mathematical Investigation
Type I: Mathematical Investigation tasks must be assessed against the following criteria.
Criterion A Use of notation and terminology
Criterion B Communication
Criterion C Mathematical process—searching for patterns
Criterion D Results—generalization
Criterion E Use of technology
Criterion F Quality of work
Assessment Criteria Mathematical Modelling
Type II: Mathematical Modelling tasks must be assessed against the following criteria.
Criterion A Use of notation and terminology
Criterion B Communication
Criterion C Mathematical process—developing a model
Criterion D Results—interpretation
Criterion E Use of technology
Criterion F Quality of work
Applying the Assessment Criteria
The method of assessment used is criterion referenced, not norm referenced. That is, the method of assessing each portfolio judges students by their performance in relation to identified assessment criteria and not in relation to the work of other students. The aim is to find, for each criterion, the level descriptor that conveys most adequately the achievement levels attained by the student.
The highest achievement levels do not imply faultless performance. The whole range of achievement levels will be be awarded as appropriate. For a particular piece of work, a student who attains a high achievement level in relation to one criterion may not necessarily attain high achievement levels in relation to other criteria. A student who attains a particular level of achievement in relation to one criterion does not necessarily attain similar levels of achievement in relation to the others.
The final mark
Each portfolio must contain two pieces of work (if more than two pieces have been completed the best two will be selected for submission). To calculate the final mark add all the achievement levels for both pieces of work together to give a total out of 40.
Criterion/tasks A B C D E F Final mark
Type I 1 3 3 2 3 2
Type II 2 3 4 2 2 2
3 + 6 + 7 + 4 + 5 + 4 = 29
The final mark is 29.
Incomplete portfolios
If only one piece of work is submitted, a zero will be awarded for each criterion for the missing work.
Non-compliant portfolios
If two pieces of work are submitted, but they do not represent a type I and a type II task (for example, they are both type I or both type II tasks), mark both tasks will be marked, but a penalty of 10 marks will be added to the final mark.
