This is the external component of the 13COMP course.

It is run as a Common Assessment Task (CAT):

• all students sit the same paper in a 3-hour slot late in term 3 / early in term 4.

• see the assessment schedule for the date.

• it is a closed book assessment using a school exam user-id to login with which has no access to the internet or your documents folder

• it is marked externally, and therefore is an external.

Computer science areas for 2020

The area of computer science will be selected from:

• complexity and tractability

• computer vision

• formal languages

The step-up in the levels of achievement

Achieved – analyse/explain:

• the key aspects of the computer science area

• relevant algorithms or other mechanisms behind the area

• how the area is used, is implemented, or occurs, giving examples.

Students use information including research and/or classwork that they have previously undertaken within a computer science area in the achievement standard. They use this information to support their statements about the key aspects, how the area is implemented and to provide reasoning for the behaviour of the algorithms or mechanisms used within their context. For example (within computer vision), how an algorithm can pick up and identify facial features.

Students will provide a detailed account of how and why a computer science area occurs, within a particular context. For example (within computer vision): detailing why and how facial recognition is used by computers to match a facial scan to the photograph embedded in an e-passport.

Merit – analyse in depth:

Students use information from research and/or classwork within the chosen computer science area to:

• provide a detailed explanation of how the technical capabilities and limitations of the area relate to humans, giving examples

• compare and contrast different perspectives on the area.

Students analyse, with examples, the capabilities and limitations of the chosen computer science area and with humans. Students break an issue into its constituent parts and look in depth at each part using supporting arguments and evidence on how perspectives for and against and how these are interrelated to one another.

Excellence – critically analyse an area of computer science involves drawing insightful conclusions about the computer science area.

Students critically analyse the computer science area by giving their reasoned verdict as to what extent a statement or findings within a piece of research are true, or to what extent they agree with them. Student may both agree with and contradict an argument using evidence taken from a wide range of sources. Students come to a final conclusion, basing their decision on what they judge to be the most important factors and justify how they have made their conclusions.
