Automotive Engineering and Technology: Section 3 Course design
Course structure
The syllabus for new courses includes the following elements.
Rationale
The rationale defines the course in terms of its unifying ideas and makes
explicit the purpose for learning in broad terms.
Course outcomes
The course outcomes are statements of what students should know,
understand, value and be able to do as a result of what they are taught and
what they learn in a course.
Course content
A broad structure for the organisation of the content is provided, along with
details about the major content areas that are further elaborated in each of
the course units.
Course units
The units and their content are structured from stage P (in some courses), to
stage 3. The cognitive difficulty of the content increases with each stage and
is referenced to the broad development of learning described in the outcome
progressions.
Time and
completion
requirements
Requirements and time allocation for course completion are outlined.
Vocational
education training
information
Information about integrating VET with courses is included for schools
wishing to provide students with the opportunity to achieve VET units of
competency while studying the course. Details of the relevant training
packages are also provided.
Resources
Any recommended or set text lists are provided here. Reference is also
made to a detailed list of relevant textbooks, teacher references, teacher
guides and manuals that can be found at
www.det.wa.edu.au/education/cmis/eval/curriculum/courses/
Assessment
The types of assessment required for the course, the weightings of these
types and the guidelines specific to the assessment for the course are
provided.
Grades
Grade descriptors are used in reporting student achievement at the end of a
course unit. The grades package for this course is available in the support
materials on the course page at
http://www.curriculum.wa.edu.au/internet/Senior_Secondary/Courses/
WACE
examination
details
Requirements for examinations are identified.
Unit syllabus
A separate syllabus is provided for each course unit. The unit syllabus
includes information about the focus of the unit, provides some suggested
learning contexts and gives details about the specific content that needs to
be taught.
Outcome
progressions
The outcome progressions describe, in broad terms, the expectations of
learning for students. In teaching a particular course unit, teachers use the
outcome progressions along with the unit content to:
 plan appropriate lessons and activities for their students
 develop specific assessment tasks and marking keys.
Automotive Engineering and Technology: Section 3 Course design
3
The relationship of outcome progressions to unit content
Outcome progressions, along with content, should be used by teachers to guide the development and
planning of their teaching and learning programs. They also provide direction in the development of
assessments and associated marking keys. Levels are not to be used as the scale to assess students
directly for reporting student performance.
The cognitive difficulty of the content of units increases with each stage (preliminary, one, two and
three) and is referenced to the broad development of learning described in the outcome progressions.
Stage P
units
Stage P units provide opportunities for practical and well supported learning to
help students develop skills required for them to be successful upon leaving
school or in the transition to stage 1 units. The content is pitched at Foundation
and levels 1–2. Post-school pathways may include TAFE and the workplace.
Stage 1
units
Stage 1 units provide bridging support and a practical and applied focus to help
students develop skills required for them to be successful upon leaving school or
in the transition to stage 2 units. The content is generally pitched at levels 3 to 4.
Post-school pathways may include TAFE, apprenticeships, traineeships and the
workplace.
Stage 2
units
Stage 2 units provide opportunities for applied learning with more focus on
academic learning for transition to stage 3. The content is generally pitched at
levels 4 to 6. Post-school options may include TAFE, apprenticeships and
traineeships, university and the workplace.
Stage 3
units
Stage 3 units provide opportunities to extend knowledge and understandings in
academic learning contexts. The content is generally pitched at levels 6 to 8. The
post-school pathway is typically university with some students opting for the
workplace or to enrol in TAFE courses.
In planning what to teach, teachers:
 read the course as a whole to understand its structure, how the content develops and to clarify the
outcomes and expectations of learning of students in each stage
 refer directly to the unit/s to be taught to determine the specific content and the learning contexts
available and the relevant parts of the outcome progressions.

Content
The course content needs to be the focus of the learning program. It enables students to maximise
their achievement of both the overarching learning outcomes from the Curriculum Framework and the
Automotive Engineering and Technology course outcomes. By engaging with this essential content,
students can demonstrate their achievement.
The course content is divided by three content organisers which are consistent across all units:
 automotive mechanics
 impact of the automotive industry
 developments in the automotive industry.
How the content spirals
Each unit is defined with a particular focus and a selection of learning contexts through which the
specific unit content can be taught and learnt. The cognitive difficulty of the content increases with
each stage and is referenced to the broad learning described in the course standards. The pitch of the
content for each stage is notional and there will be overlap between stages.
Stage 1 units provide bridging support and a practical and applied focus to help students develop
skills required to be successful for Stage 2 units. The content is typically pitched at levels 3 to 4.
Stage 2 units provide opportunities for applied learning but there is a focus more on academic
learning. The content is typically pitched at levels 4 to 6.
Stage 3 units provide opportunities to extend knowledge and understandings in challenging academic
learning contexts. The content is typically pitched at levels 6 to 8.
Through engaging with this course each of the units is designed around the same content areas
which increase in complexity from one unit to the next. This provides the framework for the scaffolding
of knowledge throughout the units as well as providing a frame of reference for monitoring student
progress. Each unit allows students to achieve all four of the course outcomes.
Unit learning foci
UNIT 1AAET: In automotive systems, students learn about basic automotive sub-systems, auto
body parts and the basic principles around which these are designed and assembled.
UNIT 1BAET: In automotive servicing, teachers can choose to focus on major sub-systems within
the automotive vehicle to allow students to gain basic practical skills in these areas.
UNIT 1CAET: In automotive tuning, teachers can choose to focus on major sub-systems within the
automotive vehicle to allow students to gain basic practical skills in complying to vehicle
manufacturer’s specifications in these areas.
UNIT 1DAET: In automotive components, students learn about basic automotive sub-systems, auto
body parts and the basic principles around which these are repaired and assembled.
UNIT 2AAET: In the world of automotive vehicles teachers may choose to introduce students to
the entire vehicle so that students will see that a vehicle is made up many different sub-systems
including the outer shell of the vehicle and how they can be modified, customized and repaired.
UNIT 2BAET: In the world of engines teachers may focus on engines so that students will gain indepth knowledge and skills in engine repair.
6
Automotive Engineering and Technology: Section 3 Course design
UNIT 3AAET: In automotive innovation and the future teachers may choose to focus on how the
automotive industry has changed in the past and how it is meeting the changing demands for the
future taking into account materials and the impact on society and the environment.
UNIT 3BAET: In automotive construction teachers may choose to focus on a project such as the
electric vehicle challenge so that students can gain skills in vehicle design, production, modification,
customisation, testing and evaluation. This unit is particularly suitable for students who are working in
integrated programs and/or workplace learning.
