q Subscribe to and read the VCAA Bulletin
q Advice for Teachers (coming out in Term 4)
• Assessment Criteria
Why change?
q More coding
• Students want more
q Options for new languages and flexibility
• Possibility for students in one class to be using different languages
q Future proofing
q Decent sized software solutions
• Apps/games/robotics etc
Key changes
q No approved programming languages list
q U4O2 – change of focus (report – no longer a test)
q School-assessed Task (project over two outcomes)
q Introduction of types of thinking

Coursework
Assessing SACs
q There will be Advice for Teachers
q Rubrics have been written by the VCAA
q Teacher still has control of SACs
q Similar to Performance Descriptors in current
Assessment Handbook, but as a rubric
q Descriptors will be read from left to right against
the Outcome statement (similar to the SAT) q More on the next slide
Assessing SACs
q Just to give you some idea of the descriptors:
• They will be a five point system from:
– Very Low, Low, Medium, High, Very High
• Include:
– Software designs
– Appropriately selected data types and data structures
– Use of appropriate processing features
– Appropriate range of test data
– Tests successfully applied
– Complete internal documentation
School-assessed Tasks
Extended project – over two outcomes
Mandated assessment criteria
Scores for each outcome are reported separately (see informatics)
Ongoing teaching/learning/assessing process
Individual projects for authentication (e.g. app;
planning project; web service, SML stream, games
SAT components
SAT U4 O1 U3 O2 Analyse and document a need or opportunity; generate alternative design ideas; preferred solution design Create a solution that fulfils requirements.Formulate project plan
Evaluate project plan
