Important Information

Changes for 2016

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

School Assessed Coursework

Unit 3 Outcome 1 - SAC

Unit 4 Outcome 2 - SAC

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 – Modules that meet requirements of designs

Questions

School Assessed Task

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
