Area of Study 1 Outcome 1

Apply stages of the problem
-
solving methodology to produce a solution for use on a mobile device,
which takes into account technical and legal requirements.

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 b
rief.

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



expre
ss 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



ap
ply 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
techni
ques



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 w
hich 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.

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 mo
bile 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 d
ata 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.

A mai
nly 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 validati
on, 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 r
equirements 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
sol
ution 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 testin
g 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 conv
entions 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 resul
ts 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.


Task 2

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

Description

User docume
ntation and an explanation of how security and legal matters are managed when creating
solutions in one of the following
:



a

written report



a

test
.

Designing the assessment task

Teachers should develop an assessment task that allows the student to:



develop
user documentation that is appropriate for the intended use and audience of the software
solution



discuss security measures that will be necessary to protect the information stored within and
communicated between, the mobile software solution and related n
etworks



explain how the software solution has taken into account the legal obligations of programmers in
the given context



have the opportunity to demonstrate the highest level of performance.

Resources and scheduling

Schools may determine the conditions f
or 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 typicall
y demonstrated within
each range on the assessment task.

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 o
f their impact on the development of the
