Informatics SAT

The Informatics SAT

An abbreviated guide for students

Based on the VCAA publication.

My unofficial additions are in italics.

The Informatics School Assessed Task (SAT) is composed of two outcomes: U3O2 and U4O1.

The SAT contributes 30% to your total Informatics study score.


U3O2

“Use a range of appropriate techniques and processes to acquire, prepare, manipulate and interpret complex data to confirm or refute a hypothesis, and formulate a project plan to manage processes.”

In U3O2, you need to create:

  1. A short report that sets out
    • a statement of a hypothesis that you generate.
    • the constraints and scope of the hypothesis
    • Your teacher cannot give the hypothesis to you.
    • Your class cannot work on the same hypothesis as a group. All work is done by yourself.
    • the key findings and conclusion that you have drawn about the hypothesis after manipulating the data (Say what you found and whether the hypothesis has been substantiated or refuted.
    • Note that a hypothesis can never be proved to be correct.)
    • an outline of the findings supporting the conclusion (an explanation of why you believe your conclusion is correct)
    • VCAA notes that there is no specified format for the report so it could be presented as a written, visual or oral report.
  2. A collection of data sets (acquired from primary and secondary sources using a range of collection methods), and information derived from them, that allows a conclusion to be drawn about the hypothesis and evidence of: 
    • the specifications for creating the information
    •  acknowledgement of intellectual property, using one of the four listed methods (Harvard, APA, Chicago, or IEEE)
    •  the validation and manipulation processes and techniques used
    •  the methods used to secure stored and communicated data and information
    • VCAA adds that: 
      • If nondigital data is acquired it needs to be digitised.
      • If qualitative data is collected, there must be evidence of how it is codified.
      • You should acquire at least two different types of data.
      • You must provide evidence (in writing or through annotations) of how the acquired data was assessed for its integrity.
      • You should also provide evidence of
        • how your files are managed (e.g.  as a folder map)
        • a listing of files
        • how these files are secured
        • how these files meet any legal requirements
      • Provide evidence of how you organised the data in readiness for
        manipulation
      • Provide evidence of the information generated from your data,
        manipulated using software appropriate to the types of data.
  3. A project plan (Gantt chart) indicating times, resources and tasks.
    • Other project management tools may also be used – e.g. a PERT chart – but the Gantt is required.
    • The Gantt chart covers the full implementation of the PSM : analysis, design, development and evaluation 
    • Therefore the Gantt will include the requirements of U4O1.
    • You will be assessed on your ability to document the key concepts and processes relevant to their project. You will not be assessed on your software skills.
    • You should take account of any assessment dates and other deadlines provided by the teacher; however all other scheduling must be determined by you.
    • As the project progresses in Unit 3, you should be recording any adjustments to your original plan.

U4O1

“Design, develop and evaluate a multimodal online solution that confirms or refutes a hypothesis, and assess the effectiveness of the project plan in managing process.”

In U4O1 you need to create:

  1. A folio of two or three alternative design ideas for your MMOS and the detailed design specifications of the preferred design.
    • List the evaluation criteria you will use to select the design idea that will be developed into the detailed design for your MMOS. Apply those criteria to select the best design idea
    • Design ideas are rough, brief and lacking detail, e.g. a sketch on a napkin about a general strategy.
    • Design ideas represent broad ideas of key appearance features and functions of possible solutions.
    • The detailed design is fully descriptive of the solution, including things like mock-ups, site maps etc.
    • The design should be able to meet the needs of educating a world-wide audience about your key findings arising from your manipulation and
      interpretation of complex data.
  2. A multimodal online solution (MMOS) that communicates the confirmation or refutation of the hypothesis you devised in U3O2.
    • Use the detailed design as the basis for developing the MMOS 
    • Apply a suite of functions within your MMOS authoring software in order
      to execute requirements identified in the VCAA Bulletin.
    • These functions may change annually.
    • The MMOS must consist of multiple pages that illustrate the connections
      between the acquired data, the findings and the conclusion with respect to the hypothesis.
    • The content should include two or more different types of data and information (text, sound, numbers, images – still and moving).
  3. An evaluation of the effectiveness of the solution.
    • Apply your criteria to evaluate the extent to which your MMOS coherently and effectively communicates your findings and conclusions.
    • Explain how each criterion is addressed in the solution, using study-specific
      language. This can be achieved through annotations or in writing.
  4. An assessment of the effectiveness of the project plan (Gantt chart) in monitoring project progress
    • Explain how your project plan (Gantt chart) assisted in monitoring the progress of the project.
    • You can use a variety of ways of showing adjustments on your plan.
    • In addition to acknowledging adjustments, you must explain the usefulness of the plan in monitoring your progress through the stages of the PSM.

Items 3 (evaluation of the MMOS) and 4 (assessment of the Gantt) need to be presented in either a written report, or an annotated visual plan.


Assessment criteria

Showing the features of high performance

Number Criterion High performance
1 Depth of understanding of formation of a hypothesis and coherence of  conclusion
  • Frames a well-informed hypothesis that identifies a specific prediction, logical variables and is testable.
  • Explains all relevant and key specific constraints on the hypothesis and explains thoroughly all aspects of the scope in terms of what will and will not be covered.
  • Identifies insightful and accurate findings based on a rigorous interpretation of the manipulated dataset.
  • Draws a valid conclusion to the hypothesis that is fully substantiated.
2  Skills in acquiring, validating and referencing data ​
  • Acquires multiple complex data sets of different types of data, qualities and structures from both primary and secondary data sources. Uses appropriate methods to acquire data from both types of sources.
  • Uses a standard referencing system and applies conventions consistently and appropriately to each data source and acquisition method. Correctly acknowledges all intellectual property.
  • Selects and applies a complete set of validation techniques that result in a dataset that has full integrity.
3 Skills in organising, manipulating and securing data and information
  • Thoroughly and systematically prepares the data for manipulation by selected software tools including codifying all qualitative data using appropriate physical techniques or software tools.
  • Uses an extensive range of digital system components, software functions, techniques, formats and conventions to manipulate the selected data to produce insightful information suitable for interpretation.
  • Documents and applies a comprehensive file management plan.
  • Selects and applies a comprehensive range of physical and software security controls to protect all stored and communicated data and information. Meets all legal requirements.
4 Depth of understanding of project management concepts and processes
  • Prepares a coherent and accurate Gantt chart using software that identifies all required project management concepts and processes.
  • Documents all stages of the problem-solving methodology in the Gantt chart, identifying conclusively all activities required for both parts of the project.
  • Accuracy, completeness and coherence of the chart contributes to an effective project management plan to monitor progress.
