This outcome will contribute 60 marks out of the 100 marks allocated to School-assessed
Coursework for Unit 4. It will be assessed by two tasks, one of which will be worth 45 marks and
the other which will be worth 15 marks.

Task 1
Description
A solution (including internal documentation) in response to a design brief.
Designing the assessment task
Teachers should develop an assessment task that allows the student to:
 apply the relevant stages of the problem-solving methodology (design and development) to
    produce a prototype solution for use on a mobile phone
 express the logic of the software solution through the use of algorithms
 express the software solution design using appropriate methods and techniques
 use a programming language selected from the list published annually in the VCAA Bulletin VCE,
    VCAL and VET
 apply programming skills to create a software solution suitable for use on a mobile device
 include internal documentation within the software solution
      verify the performance of the software solution by selecting suitable test data and applying testing
       techniques
      have the opportunity to demonstrate the highest level of performance.
Resources and scheduling
Schools may determine the conditions for the task including access to resources and notes. Students
should be advised of the timeline and conditions under which the task is to be conducted.
Performance descriptors
The following descriptors provide a guide to the levels of performance typically demonstrated within
each range on the assessment task/s.

    MARK RANGE              DESCRIPTOR: typical performance in each range

    37–45 marks             An accurate interpretation of the provided software requirements
                            specifications is evident in the design of a feasible solution. The design
                            of the software solution is clear, technically accurate and takes into
                            account the constraints of the mobile device. The algorithm is clearly
                            written and logically represents what is required. The software solution
                            conforms to all accepted coding conventions and includes appropriate
                            and clear internal documentation. All techniques and procedures,
                            including data validation, are efficiently and effectively applied. A
                            comprehensive range of test data is expressed in a testing table, with the
                            expected and actual output stated. The solution meets all of the software
                            requirements specifications.
    28–36 marks          A mainly accurate interpretation of the provided software requirements
                         specifications is evident in the design of a feasible solution. The design
                         of the software solution is clear and mostly takes into account the
                         constraints of the mobile device. The algorithm is clearly written and
                         logically represents most of what is required. The software solution
                         conforms to most accepted coding conventions and includes appropriate
                         and formatted internal documentation. Most techniques and procedures,
                         including data validation, are efficiently and effectively applied. A range
                         of test data is expressed in a testing table, with the expected and actual
                         output stated. The solution meets many of the software requirements
                         specifications.

    19–27 marks          Most of the provided software requirements specifications are evident in
                         the design of a solution, and most of the key requirements are represented
                         in an algorithm. The design of the software solution considers the
                         constraints of the mobile device in some relevant ways. The software
                         solution conforms to many of the accepted coding conventions and
                         includes at least some appropriate internal documentation. There is
                         evidence of techniques and procedures, including data validation, being
                         applied. A range of test data is expressed in a testing table, with the
                         expected and actual output stated. The solution attempts to meet the
                         software requirements specifications.

    10–18 marks          Some interpretations of the provided software requirements
                         specifications result in some key requirements being evident in the
                         design of a solution. The design of the software solution considers few of
                         the constraints of the mobile device. Some of the key requirements are
                         represented in an algorithm. The software solution conforms to some of
                         the accepted coding conventions and includes a few instances of internal
                         documentation. There is some evidence of techniques and procedures,
                         including data validation, being applied. An incomplete range of test data
                         is expressed in a testing table, with some evidence of the results of these
                         tests shown. The solution meets few of the software requirements
                         specifications.

    1–9 marks            Limited interpretation of the provided software requirements
                         specifications results in few key requirements being evident in the design
                         of the solution. Few constraints related to mobile devices have been
                         considered in the design of the software solution. The algorithm has met
                         limited requirements. Limited coding conventions are applied in the
                         software solution and there is limited internal documentation. Few
                         techniques or procedures have been applied. An inadequate range of test
                         data is expressed in a testing table, with little evidence presented. The
                         solution meets very limited software requirements specifications.

 MARK RANGE               DESCRIPTOR: typical performance in each range

 13–15 marks              User documentation is appropriate, logically sequenced, complete and
                          accurate. Presentation is clear and consistent with generally accepted
                          conventions. All proposed measures to meet the security requirements of
                          the solution are appropriate and achievable. Thorough and well-
                          developed analysis of all relevant legal obligations within the given
                          context and a clear discussion of their impact on the development of the
                          programming solution. All relevant laws are correctly interpreted and
                          applied within the given context and their significance is clearly
                          explained.

 10–12 marks              User documentation is generally appropriate and logically sequenced.
                          Presentation conforms to most generally accepted conventions. Most
                          proposed measures to meet the security requirements of the solution are
                          achievable. Careful analysis of most of the legal obligations within the
                          given context and a clear discussion of their impact on the development
                          of the programming solution. Relevant laws are correctly interpreted and
                          applied within the given context and their significance is explained.

 7–9 marks                User documentation is appropriate, and the presentation conforms to
                          some generally accepted conventions. Some proposed measures to meet
                          the security requirements of the solution are achievable. Legal
                          obligations within the given context are discussed together with their
                          impact on the development of the programming solution. Some of the
                          relevant laws are correctly interpreted and applied within the given
                          context and their significance is mentioned.

 4–6 marks                User documentation demonstrates limited sequencing and coverage and
                          the presentation conforms to limited generally accepted conventions.
                          Limited security requirements of the solution are outlined and at least one
                          proposed measure is achievable. Legal obligations within the given
                          context are outlined. Some relevant laws are interpreted within the given
                          context.

 1–3 marks                User documentation demonstrates limited sequencing and coverage and
                          the presentation conforms to few generally accepted conventions. Few
                          security requirements and measures are outlined. The legal obligations
                          identified reveal a limited understanding of the impact that these have on
                          the development of the programming solution.
