Unit rationale, description and aim

All students benefit from being able to solve problems through systems, design, and computational thinking and being able to design and use the electromechanical technologies that shape our world.

To align their work to the Australian Curriculum: Design and Technologies, and to function as secondary teaching professionals in the Technologies discipline, students must undertake a sequence of technologies units to acquire conceptual, procedural and professional levels of discipline specific technologies subject content knowledge and skills in electromechanical and engineering technologies. This unit provides an opportunity for students to attain and apply knowledge and skills in science, mathematics, electronics, and programming to the design, manufacture, programming, and testing of electromechanical technologies.

Students will develop knowledge of how past, present, and emerging electromechanical technologies influence principles and processes of control systems design and production through examples and case-studies. Students will consider the implications modern manufacture technologies and Industry 4.0 on society and how this relates to preferred futures. Students will develop knowledge of the design and manufacture of electromechanical systems including electronics and principles of mechanical engineering and demonstrate appropriate safe use of electronics in design. Practical skills will be developed through the design and manufacture of electronically controlled products using a range of techniques and industrial materials including CAD/ CAM technologies.

The aim of this unit is for students to be introduced to and then explore electromechanical design and manufacture and consider how they can be applied in design contexts and their teaching practice.

Learning and teaching strategy and rationale

A student-focused, problem-based learning approach is used in this unit. Students encounter concepts and principles of electromechanical systems design theory through interactive lectures, concepts are discussed and broadened through analysis of specific case studies and further informed by independent research during development of design projects. In practical workshops students design, manufacture and evaluate electronic and mechanical components. Issues in electromechanical systems design and manufacture are introduced through a practice-oriented learning method. This method involves the parallel development of procedural and conceptual skills required for design, development, and documentation of electromechanical systems. Students develop solutions to electromechanical system design problems using a design thinking methodology and a user-centred design approach. They develop conceptual knowledge in electronics and programming in addition to procedural knowledge of mechanical engineering and manufacturing technologies through practical design projects. Students design, manufacture, communicate and evaluate items against principles of electromechanical system design. These methods enable the development of conceptual, procedural and professional knowledge and skill which allows students to practice design thinking and problem solving in electromechanical technologies design contexts and to develop effective teaching strategies to develop knowledge, skills, problem-solving, and critical and creative thinking practice design thinking and problem solving in design technologies contexts.

This is a 10-credit point unit and has been designed to ensure that the time needed to complete the required volume of learning to the requisite standard is approximately 150 hours in total across the semester. To achieve a passing standard in this unit, students will find it helpful to engage in the full range of learning activities and assessments utilised in this unit, as described in the learning and teaching strategy and the assessment strategy. The learning and teaching and assessment strategies include a range of approaches to support your learning such as reading, discussion, video, independent research, design project management, lab reports, workshop logs, report writing, design projects, including design folios etc.

The unit is hosted on a Learning Management System (LMS) site with resources and online links, announcements, and a discussion board to post questions and reflections that promote connection between content and educational experiences.

Active learning opportunities provide students with opportunities to practice and apply their learning. Activities encourage students to bring their own examples to demonstrate understanding, application and engage constructively with their peers. Students receive regular and timely feedback on their learning, which includes information on their progress.

Assessment strategy and rationale

The problem-based learning strategy employed in this unit is supported by the integration of progressive authentic assessment tasks completed at critical points in the students’ learning. Theoretical and conceptual knowledge and practical skills-based knowledge are developed simultaneously in that acquisition and assimilation of knowledge develops as students undertake project-based learning and complete self-guided design projects. Initially, students acquire knowledge in electromechanical design by undertaking tutorial exercises and developing a research-based report on key concepts introduced in the lectures. They develop skills in design and manufacture through practical workshop classes, which may be conducted through mixed-mode delivery, i.e. in-person where applicable, remotely if facilities are available, or via on-campus intensives. Practical workshops provide opportunities for formative assessment which supports assimilation of knowledge. In this unit the method aims to assess students’ achievement of a synthesis between design theory, practice, and application of mathematical principles in electromechanical design. Therefore, a key assessment method used is project-based learning through self-guided major design projects which includes multiple components, namely a design documentation ePortfolio and a designed and manufactured product(s). ePortfolios document students’ design processes and include evidence of project definition, research, ideation, prototyping, iteration, critical evaluation, and risk assessment. The summative program planning assessment aims to assess students’ application of knowledge and skills (conceptual, procedural, and professional) and competencies holistically using an integrated approach common in design education which focusses on the assessment of an entire design activity rather than specific elements in isolation. Building upon the earlier assessments undertaken by students, to provide them with applicable teaching strategies upon completion of this unit, acquired technical skills are combined with pedagogical practice. This allows students to effectively establish sound teaching practices through mirroring their role in this unit with that of their future students, while also researching and analysing Australian teaching standards for Design and Technology and STEM.

A range of assessment procedures will be used to meet the unit objectives consistent with University assessment requirements. Such procedures may include research reports, a design project with an ePortfolio, and learning-program design. Assessment tasks will address all learning outcomes as well as relevant graduate attributes.
