REVIEW OF VCE INFORMATION TECHNOLOGY
SUMMARY OF PROPOSED CHANGES TO THE STUDY DESIGN
Teachers should note that the proposed new name for this study is VCE Computing.
GENERAL CHANGES
The review process for VCE Information Technology focused on:

Nomenclature, in particular the name of the study and IT applications





Increasing the level of creativity in all units
Incorporating an assessment regime that supported the creation of complex solutions to
real problems
Clarifying the focus of the study, in particular IT applications
Making connections to the Australian Curriculum: Digital Technologies
Including a conceptual framework to support teaching and learning practice.
SPECIFIC CHANGES
Four key concepts that underpin the study are represented in the study design as organisers
of key knowledge. The concepts are:




Data and information
Digital systems
Interactions and impact
Approaches to problem solving.
They are intended to:




Provide a framework for knowledge and practice
Establish a way of thinking about problems, opportunities and digital systems
Provide developmental threads through each area of study and unit
Provide unifying themes that support transferability of knowledge and hence deeper
learning.
The concepts do not have separate content, but rather they classify key knowledge, indicated
by headings.
Unit 1: Computing
There has been a shift in the focus of this unit from individuals, organisations and information
systems to data, information and networked digital systems. As a consequence some
structural and content changes have been made. There is greater flexibility in the software
tools used to create solutions, and spreadsheet software is no longer mandated.
Computational, design and systems thinking skills are covered across the unit and are
reflected in the outcome statements. Area of Study 1 is new, Area of Study 2 (Networks) has
changed slightly, and Area of Study 3 has changed its name from ICT in a global society and
has slightly modified content.

SUMMARY OF PROPOSED CHANGES
Unit 2: Computing
Conceptually there has been a slight shift with a stronger focus on the creation of solutions
that automate the processing of data through the use of programming or scripting languages
and flat file database management systems software. Two areas of study are similar to the
current study with one being replaced, (Tools, techniques and procedures). The new area of
study is Data management that requires students to determine their own need or opportunity,
collect relevant data and engage in all stages of the problem-solving methodology to create a
solution using a flat database management system.
Unit 2: Computing
i. Area of Study 1: Programming
ii. Area of Study 2: Data analysis and visualisation
iii. Area of Study 3: Data management
Unit 3: Informatics
Significant changes have been proposed for Informatics (new name to replace
IT applications), stemming primarily from the incorporation of a School-assessed Task (SAT).
Two areas of study comprise the School-assessed Task; Unit 3, Area of Study 2 and Unit 4,
Area of Study 1. The SAT allows students to create real-world digital solutions through project
work over an extended period of time. The conditions of a SAT allow students to be assessed
on process as well as product, and it allows students to create meaningful and complex digital
solutions. There are no restrictions on the software tool/s used for the SAT. In Unit 3, Area of
Study 2 student frame a hypothesis, and identify, collect and organise data in readiness for
interpretation in Unit 4. The also create a project management plan for the SAT.
The title of the units has changed and the existing area of study: Online communities has
been replaced with the Organisations and data management, which is the current Area of
Study 2, with some modifications. One of the assessment tasks for this outcome requires
students to trace the interactions that a user has when engaging in an online transaction.
Students must acknowledge the multiple entry points to a website and identify the sequence
of web pages that must be visited to commence and conclude a transaction. User flow
diagrams document the user’s journey.
Unit 3: Informatics
i. Area of Study 1: Organisations and data management
ii. Area of Study 2: Data analytics
Unit 4: Informatics
In Unit 4, students continue working on their project that forms the SAT. They extract meaning
from the data prepared in Unit 3 and formulate a conclusion to their hypothesis. Students
design, develop and evaluate a solution that communicates their conclusion. They use their
project plan to monitor progress, and evaluate its success in coordinating time, resources and
tasks.
Minor changes have been made to Area of Study 2: Information management, primarily to
reduce scope. The outcome statement is slightly reworded and students only consider
information management strategies for the storage and disposal of data and information.

SUMMARY OF PROPOSED CHANGES
Unit 3: Software development
The name of this Unit 3–4 study is unchanged. The programming language used in both units
does not have to be selected from a list approved by the VCAA, hence there is greater
flexibility at the school level. As is the current situation, the VCAA will continue to publish a list
of programming language capabilities.
The introduction of a School-assessed Task (SAT) has resulted in content and structural
changes in this unit. Two areas of study comprise the School-assessed Task (SAT); Unit 3,
Area of Study 2 and Unit 4, Area of Study 1. The SAT allows students to create real-world
digital solutions through project work. The conditions of a SAT allow students to be assessed
on process as well as product, and it allows students to create meaningful and complex digital
solutions. In Unit 3, Area of Study 2 students identify a problem, need or opportunity and
engage in the problem-solving methodology stages of analysis and design. They also prepare
a project management plan for the complete SAT using dedicated software.
Area of Study 1: Programming practice replaces the current Analysing information problems,
with the analysis work now being located in Area of Study 2. Area of Study 1 is similar to the
current Area of Study 2, with the focus on students developing knowledge and skills in using a
programming language for the purpose of creating working modules.
Unit 3: Software development
i. Area of Study 1: Programming practice
ii. Area of Study 2: Software architecture
Unit 4: Software development
In Unit 4, students continue working on their project that forms the SAT. They develop their
preferred design specifications and evaluate the efficiency and effectiveness of the solution
and the effectiveness of their project plan as a mechanism for managing projects. During the
development stage they create user documentation for a segment of the solution and conduct
authenticate usability tests, incorporating feedback into their solution.
Area of Study 2: Interactions and impact is new. Its focus is on data ownership and security,
and ethical responsibilities and legal obligations, viewed from a systems perspective through
the lens of personal data.
