Technological systems play an increasingly significant role in the human world. They mediate or control many aspects of human experience. Systems Engineering provides an opportunity for students to develop capabilities in, and knowledge about, the design, operation, construction, assembly, maintenance, diagnosis, repair and evaluation of technological systems, applicable to a diverse range of fields such as engineering, manufacturing, automation, control technologies, mechatronics, electrotechnology, robotics, and energy management. Students gain awareness and understanding of the interactions of these systems with human society and natural ecosystems. Students will gain appreciation, knowledge, understanding, and practical application of technological systems. The study promotes innovative thinking and problem-solving skills through a project-based learning approach. It provides opportunities for students to learn about and engage with systems from a practical and purposeful perspective. The study emphasises integration of basic engineering and physics theory with practical tasks. Technological principles and the associated mathematics are incorporated as essential tools employed in the processes of technological systems design, modification, production and evaluation. The terms mechanical and electrotechnology are used as descriptors for the types of systems covered by this study. Mechanical systems include pneumatic and hydraulic systems or subsystems. Electrotechnology systems include electrical, electronic and microelectronic systems or subsystems. The study can provide a sound basis for entry into a broad range of tertiary technology courses such as engineering and applied sciences, skilled trades and vocational training, in the electrotechnology and automotive sectors or lead to employment in technological enterprises.

VCE STUDY DESIGN 9 May 2010 Introduction SYSTEMS ENGINEERING KEY COMPETENCIES AND EMPLOYABILITY SKILLS This study offers a number of opportunities for students to develop key competencies and employability skills. The Advice for Teachers section provides specific examples of how students can demonstrate key competencies during learning activities and assessment tasks. LEGISLATIVE COMPLIANCE When collecting and using information, the provisions of privacy and copyright legislation, such as the Victorian Information Privacy Act 2000 and Health Records Act 2001, and the federal Privacy Act 1988 and Copyright Act 1968 must be met. 10 VCE STUDY DESIGN May 2010 Assessment and reporting SATISFACTORY COMPLETION The award of satisfactory completion for a unit is based on a decision that the student has demonstrated achievement of the set of outcomes specified for the unit. This decision will be based on the teacher’s assessment of the student’s performance on assessment tasks designated for the unit. Designated assessment tasks are provided in the details for each unit. The Victorian Curriculum and Assessment Authority publishes an assessment handbook that includes advice on the assessment tasks and performance descriptors for assessment for Units 3 and 4. Teachers must develop courses that provide opportunities for students to demonstrate achievement of outcomes. Examples of learning activities are provided in the Advice for Teachers section. Schools will report a result for each unit to the Victorian Curriculum and Assessment Authority as S (Satisfactory) or N (Not Satisfactory). Completion of a unit will be reported on the Statement of Results issued by the Victorian Curriculum and Assessment Authority as S (Satisfactory) or N (Not Satisfactory). Schools may report additional information on levels of achievement. AUTHENTICATION Work related to the outcomes will be accepted only if the teacher can attest that, to the best of their knowledge, all unacknowledged work is the student’s own. Teachers need to refer to the current year’s VCE and VCAL Administrative Handbook for authentication procedures. LEVELS OF ACHIEVEMENT Units 1 and 2 Procedures for the assessment of levels of achievement in Units 1 and 2 are a matter for school decision. Assessment of levels of achievement for these units will not be reported to the Victorian Curriculum and Assessment Authority. Schools may choose to report levels of achievement using grades, descriptive statements or other indicators. 11 May 2010 Assessment and reporting SYSTEMS ENGINEERING Units 3 and 4 The Victorian Curriculum and Assessment Authority will supervise the assessment of all students undertaking Units 3 and 4. In Systems Engineering the student’s level of achievement will be determined by school-assessed coursework, a school-assessed task and an end-of-year examination. The Victorian Curriculum and Assessment Authority will report the student’s level of performance on each assessment component as a grade from A+ to E or UG (ungraded). To receive a study score, students must achieve two or more graded assessments and receive S for both Units 3 and 4. The study score is reported on a scale of 0–50. It is a measure of how well the student performed in relation to all others who took the study. Teachers should refer to the current year’s VCE and VCAL Administrative Handbook for details on graded assessment and calculation of the study score. Percentage contributions to the study score in Systems Engineering are as follows: • Unit 3 school-assessed coursework: 12 per cent • Unit 4 school-assessed coursework: 8 per cent • Units 3 and 4 school-assessed task: 50 per cent • End-of-year examination: 30 per cent Details of the assessment program are described in the sections on Units 3 and 4 in this study design. 12 VCE STUDY DESIGN May 2010 Unit 1: Mechanical engineering fundamentals This unit focuses on mechanical engineering fundamentals as the basis of understanding the underlying principles and the building blocks that operate in the simplest to more complex mechanical devices. While this unit contains the fundamental physics and theoretical understanding of mechanical systems and how they work, the main focus is on the construction of a system. The construction process draws heavily upon design and innovation within all the interrelated applied learning activities. In this unit, students study fundamental mechanical engineering principles, including the representation of mechanical devices, the motions performed, the elementary applied physics, and the mathematical calculations that can be applied in order to define and explain the physical characteristics. The unit allows for a ‘hands-on’ approach, as students apply their knowledge and construct functional systems. These systems can be purely mechanical or have some level of integration with electrotech systems. The systems constructed can provide tangible and/or realistic demonstrations of some of the theoretical principles studied in this unit. All systems require some form of energy to function. Through applied research, students explore how these systems use or convert the energy supplied to them, and related wider environmental and social issues. AREA OF STUDY 1 Fundamentals of mechanical technological systems This area of study focuses on the fundamental engineering principles and the elements required to constitute an operational mechanical system. The inclusive term ‘mechanical systems’ includes systems that utilise all forms of mechanical linkages, as well as hydraulic and pneumatic systems. Students learn the fundamental principles of how mechanisms and simple mechanical systems provide movement and mechanical advantage, and how the specific parts of a system or an entire mechanical system can be represented diagrammatically. An understanding of mechanical systems and their operation are reliant on the theoretical principles from foundation physics and applied mathematics. 13 May 2010 Unit 1 SYSTEMS ENGINEERING Outcome 1 On completion of this unit the student should be able to recognise, identify, illustrate and use theoretical principles of mechanical systems.

Following planning, the production stage requires materials fabrication, risk management, selection and safe use of tools, equipment and machines. Students document the technological processes undertaken including decisions made in relation to the design, developmental planning and safe manufacture of the system/s. While it is expected that the functional system will have significant mechanical components, the system could integrate mechanical and electrotech systems.

VCE STUDY DESIGN 15 May 2010 Unit 1 SYSTEMS ENGINEERING AREA OF STUDY 3 Analysing a technological system in society In this area of study students explore and investigate a technological system. Students gain a greater technical understanding and knowledge of the components, subsystems and their interrelationship and function within the system. Students also gain an appreciation of how trade-offs are applied, as these systems are designed to bring benefit, but also usually have some wider detriment to the broader society. Examples of appropriate technological systems for analysis are included in the Advice for Teachers section. Outcome 3 On completion of this unit the student should be able to analyse a technological system in terms of its operation, function, energy use and social and environmental implications. To achieve this outcome the student will draw on knowledge and related skills outlined in area of study 3.

This decision will be based on the teacher’s assessment of the student’s overall performance on assessment tasks designated for the unit. The key knowledge and skills listed for each outcome should be used as a guide to course design and the development of learning activities. The key knowledge and skills do not constitute a checklist and such an approach is not necessary or desirable for determining the achievement of outcomes. The elements of key knowledge and skills should not be assessed separately. Assessment tasks must be a part of the regular teaching and learning program and must not unduly add to the workload associated with that program. They must be completed mainly in class and within a limited timeframe. Teachers should select a variety of assessment tasks for their assessment program to reflect the key knowledge and skills being assessed and to provide for different learning styles. For this unit students are required to demonstrate achievement of three outcomes. As a set these outcomes encompass all areas of study. Demonstration of achievement of Outcomes 1, 2 and 3 must be based on the student’s performance on a selection of assessment tasks. Where teachers allow students to choose between tasks they must ensure that the tasks they set are of comparable scope and demand. Assessment tasks for this unit are: • records/folio of design, planning and production; • production work; • annotated visual displays; • website presentations; • tests (short and/or extended answer); • practical tests; • practical demonstrations; • short written reports (for example, technical reports, industry visit reports, production evaluation reports); • oral reports supported by multimedia presentations. VCE STUDY DESIGN 17 May 2010 Unit 2: Electrotechnology engineering fundamentals This unit focuses on building understanding of the fundamental principles of electrical and electronic circuits, collectively and commonly referred to as electrotechnology. In this unit students study fundamental electrotechnology engineering principles. Through the application of their knowledge students produce basic operational systems. The systems produced by the students should employ a level of integration between mechanical and electronic components. Students also apply their knowledge and skills to research and produce technical reports. While this unit contains the fundamental physics and theoretical understanding of electrotechnology systems and how they work, the main focus remains on the construction of electrotechnology systems. The construction process heavily draws upon design and innovation within all the interrelated applied learning that occurs in the unit. In this unit, students study fundamental electrotechnology principles including applied electrical theory, representation of electronic components and devices, elementary applied physics in electrical circuits, and mathematical calculations that can be applied in order to define and explain electrical characteristics of circuits. The unit offers opportunities for students to apply their knowledge in the construction of a functional system. Although the system can be predominately electrotechnological, it is highly desirable to have some mechanical integration within the system. The systems constructed provide a tangible demonstration of some of the theoretical principles studied in this unit. Electrotechnology is one of the fastest moving sectors in relation to developments and changes that are taking place through technological innovation. The contemporary design and manufacture of electronic equipment involves increased levels of automation and inbuilt control.

The areas of study describe the learning context and the knowledge required for the demonstration of each outcome. Outcomes are introduced by summary statements and are followed by the key knowledge and skills which relate to the outcomes. Teachers must develop courses that include appropriate learning activities to enable students to develop the key knowledge and skills identified in the outcome statements in each unit. For Units 1 and 2, teachers must select assessment tasks from the list provided. Tasks should provide a variety and the mix of tasks should reflect the fact that different types of tasks suit different knowledge and skills and different learning styles. Tasks do not have to be lengthy to make a decision about student demonstration of achievement of an outcome. In Units 3 and 4, assessment is more structured. For some outcomes, or aspects of an outcome, the assessment tasks are prescribed. The contribution that each outcome makes to the total score for school-assessed coursework and the school-assessed task is also stipulated. When developing a course for any unit within Systems Engineering it is important to remember that the outcomes and areas of study need not be taught in any specified order. This will depend on factors such as the class time available, class size, and prior experience of the students. As with planning any course of study, the structure and timelines that a teacher uses are critical to the smooth running of the course. It is suggested that a timeline is prepared for all units and used both by the students and teachers. The timeline should indicate when learning activities and assessment tasks will be done (including aspects of outcomes that will be covered concurrently), and helps to manage the time available in the semester. As a planning tool, the timeline can be as detailed or as simple as needed and can include topic headings, reminders, public holidays, curriculum days and so on. A sample timeline for Units 3 and 4 is included on pages 43–44. Unit 1, areas of study 1 and 2 are intended to be a fundamental introduction to concepts, skills and knowledge of mechanical engineering. As such, a range of approaches can be taken, depending on the teacher’s preference and the range of abilities within the class. One approach could be to select a common mechanical system such as a bicycle as a focus for all three outcomes. Alternatively, a range of both simple and complex mechanical systems can be offered so a system that suits individual student’s ability and interests can be selected. Examples could include a can opener, scissors, tinsnips, an egg beater, a hand drill, a bench vice, bench shears, a guillotine, bicycle brakes, bicycle gears, a boat winch, a hand winch, block and tackle, scissor lift, conveyor belt, windmill, vending machine, music box, and the following motor vehicle subsystems: gearbox, steering system, manual window winder, windscreen wiper mechanism, parking brake and hydraulic brakes. The selection of a real mechanical system allows the student to identify and observe the principles in action. 41 May 2010 Advice for teachers SYSTEMS ENGINEERING A similar approach can be taken with Unit 2. Examples of electrotechnology systems could include electronic kits, battery powered toys, remote controlled machines, cordless appliances and power tools. Due to the safety issues with 240V equipment, use of mains powered electrical products is limited to those with the power cord cut off or extra low voltage devices powered by batteries, such as cordless power drills and tools. An alternative approach for Outcome 2 in both Units 1 and 2 is for the teacher to select a theme and/or develop a design brief for/with students. Once the planning is underway the teacher can introduce learning activities followed by assessment tasks associated with Outcome 1. If a design brief approach is used it should be remembered that Units 1 and 2 provide an introduction to the fundamentals of mechanical and electrotechnology systems, and tasks should be appropriate in terms of developing students’ knowledge and building on prior experience. Examples of Unit 1 production work could include ‘select and assemble model kits’ that include mechanical subsystems, design and production of an aluminum can crusher, adapting bicycle gearing systems for alternative uses and models that simulate hydraulic or pneumatic systems. Products students could make in Unit 2 include simple electronic kits with a control function, programmable kits such as PICAXE, electromechanical models such as remote controlled vehicles and robotic models. It should be remembered that a degree of integration at both Units 1 and 2 is acceptable and indeed encouraged. However, the emphasis should remain on mechanical knowledge and skills in Unit 1 and electrotechnology knowledge and skills in Unit 2. Key knowledge and an associated key skill in Unit 2, Outcome 2, relates to Australian Standards. Students are not expected to have an indepth understanding of Australian Standards. The identification of one or two standards relevant to the product, components or processes is adequate. For summaries of standards, refer to the Resources section for the Standards Australia website. The search by subject facility can be a useful starting point. Unit 1, Outcome 3, does not need to focus specifically on a mechanical system. The teacher may choose to nominate a system and have students select a method of presenting their research findings. Another approach is to let the students select from a list of systems with a specified method of presenting their findings. Unit 2, Outcome 3, can be approached in a similar way with the degree of choice being broad or limited. The emerging technologies selected should be primarily related to technological systems, although new or emerging materials related to a system can be investigated. Key knowledge associated with area of study 1 in Units 1 and 2 lists foundation principles. These foundation principles are sequential in that they can be considered core knowledge for students continuing with Systems Engineering in Units 3 and 4. Further principles are added to the foundation principles in Units 3 and 4; therefore, a more indepth coverage of the foundation principles will be required for students who do not have prior understanding of these principles. Teachers should refer to the Table of Electronic symbols on the Systems Engineering page of the Victorian Curriculum and Assessment Authority website when covering the key knowledge and skills related to symbolic representation of electrotechnology systems in Units 2 and 3. Area of study 1 in Unit 3 can be approached in a similar way to Units 1 and 2 but with an emphasis on principles of controlled integrated systems. Teaching of all outcomes in the unit could be connected through the major production work undertaken as part of Outcome 2. Students in a class can share their knowledge with others when they complete different systems products. This approach allows students to apply principles to a product they are familiar with whilst developing an understanding of the principles that apply to the product they are designing and producing. Alternatively, students individually or in small groups could learn from a range of small low voltage products. Examples include sewing machines and cordless power tools which can be often sourced cheaply through clearance shops. Some 240V products could be used provided that the cord is cut off to prevent access to mains power. This can be a good use for obsolete or damaged products that would otherwise be thrown out. As with Units 1 and 2, this approach allows the students to experience real products in order to develop their understanding. 42 VCE STUDY DESIGN May 2010 Advice for teachers SYSTEMS ENGINEERING Area of study 3 in Unit 3 focuses on the relationship between energy, the environment and systems. This may be approached primarily through research and an investigation task and may be related to the school-assessed task, depending on whether the product uses an alternative energy source to batteries or transformers, e.g. solar or wind powered. Whichever approach is taken, it will need to involve significant research including current and evolving sources of energy, as this area is undergoing rapid change. For example, transport, both public and private, and related energy use and environmental effects is going through a period of change. Consequently, a vast amount of resources for both teachers and students is available. Other areas to focus on could include electricity generation, bio-fuels, solar, nuclear and hydrogen fuel cells. When commencing Units 3 and 4 it is important to recognise that time management is integral to the students’ success. Although they are two distinct units it is helpful to prepare a timeline for the whole school year. The timeline should show the key dates for assessment tasks, outcomes, exams (Systems Engineering and others), public holidays, curriculum days, term breaks and any other relevant school information. It can be a valuable planning tool for teachers and students alike. Following is a sample timeline. Week no.

When students begin planning for the school-assessed task it is important for teachers to adequately monitor and advise students on their selection. Given the fixed timeframe for this task the degree of difficulty of the selected system must be within the student’s ability. This is particularly important if the student is undertaking Units 3 and 4 without having undertaken Units 1 and 2. In this situation, tasks that involve the integration of kit-based subsystems can provide opportunities for the student to complete an operational integrated system that meets the requirements of the outcome. The design phase involves correct identification and selection of subsystems needed to work together to form a solution to the student’s design brief. The selection of a product needs careful consideration to ensure the student has ample opportunity to meet all the requirements of the task including diagnostic practices. Wherever possible, teachers are encouraged to integrate practical work with theoretical knowledge to provide opportunities for students to enhance their understanding of key knowledge through practical application of skills. USE OF INFORMATION AND COMMUNICATIONS TECHNOLOGY In designing courses and developing learning activities for Systems Engineering teachers should make use of applications of information and communications technology and learning technologies, such as computer-based learning, multimedia and the World Wide Web, where appropriate and applicable to teaching and learning activities. 44 VCE STUDY DESIGN May 2010 Advice for teachers SYSTEMS ENGINEERING Systems Engineering is very well suited to the appropriate use of electronic and computer-based learning technologies in the areas of: • computer-aided design (CAD); • computer-aided manufacture (CAM); • simulation of systems/elements/components and associated technological principles; • undertaking operational calculations for systems, their subsystems and components; • control of systems; • diagnosis of faults and problem solving; • maintenance of systems; • access to relevant technical and general information; • communicating and presenting concepts, findings and information, and preparing reports. In Systems Engineering, it is expected that students will access and present information about the role of systems in society, systems design, component data and relevant organisations by using multimedia applications and the Internet. Computer-aided design (CAD) software could be used to complement other methods of drawing and communicating ideas and solutions. Typical drawing packages such as TurboCAD, AutoCAD, TriCAD, ProDESKTOP and the Autodesk Inventor Series can be introduced to develop two- and three-dimensional presentations and modelling. Crocodile Technology can be used for electrical, electronic and mechanical design and simulation. Computer control resources are increasingly used for integration and control of systems and for manufacturing (CAM). Lego Dacta Control Lab, Festo Didactic Learning Systems and PICAXE are examples of systems control software that can be used with CAM hardware and software for production. Specific programs such as Excel could be used for spreadsheets when developing component and parts lists. General application programs such as Microsoft Office have a range of applications including word processing for reports and folio preparation, spreadsheets for calculating and presenting data, and presentation software to present research findings. Digital imagery is useful when enhancing folios, describing tools and processes and systems’ operations. Documentation of all facets of work developed during the design process can be presented in a digital multimedia portfolio. KEY COMPETENCIES AND EMPLOYABILITY SKILLS Students undertaking the following types of assessment, in addition to demonstrating their understanding and mastery of the content of the study, typically demonstrate the following key competencies and employability skills.

One problem associated with recycling aluminium cans is their size to weight ratio. In order for a can recycling program to be worthwhile, the cans must be crushed quickly and efficiently; but how can this be done when there are literally hundreds of cans to be squashed daily? Students design and produce a machine for crushing aluminium cans quickly and efficiently. Design criteria: • must be able to be wall mounted • easily used by a range of people from Year 7 students through to stronger adults 48 • able to be operated with one hand • must be easily operated by either right or lefthanded people. To help students design the product, they should research: • mechanical principles such force, types of motion, load, effort, mechanical advantage, energy, efficiency, friction, action and reaction forces, moments about a point and gear ratios • components such as screws, inclined planes, levers, linkages, cranks, gears, cams and followers, belts and pulleys.

Model solar powered car speed is determined by the efficiency of all electrical and mechanical subsystems – cells, motors, gears, wheels etc. To maximise speed, the optimum solar cell output for the selected motor needs to be established. • Design and perform tests to measure effects of gear ratio changes, wheel sizes, model mass, friction and aerodynamics. This activity requires modelling of different wiring configurations for solar cells and testing for performance variations. Testing the efficiency of the mechanical subsystems of each model will also be required. • Use a simulation program to model the electrical/electronic and gearing systems. Use this program to prepare circuit diagrams of the design. Students record the results of their tests and use this to present to the class as justification for the design and selection of wiring and components. To complete the activity, students: • Use a light meter to measure the light conditions and record the results for each test.

VCE STUDY DESIGN 57 May 2010 Advice for teachers SYSTEMS ENGINEERING School-assessed coursework In Units 3 and 4 teachers must select appropriate tasks from the assessment table provided for each unit. Advice on the assessment tasks and performance descriptors to assist teachers in designing and marking assessment tasks will be published by the Victorian Curriculum and Assessment Authority in an assessment handbook. The following is an example of a teacher’s assessment program using a selection of the tasks from the Units 3 and 4 assessment tables.
