TECH 2001 - Electrical Principles

North Terrace Campus - Semester 1 - 2022

This course covers the fundamental principles of analog and digital circuits and electronic devices. This knowledge is critical for students needing to work on or with electrical systems within larger engineering systems. The course seeks to develop foundational concepts and skills and complements the material with a series of application-oriented topics relevant to defence industries. Important topics covered include: the key electrical variables and the application of fundamental circuit laws and theorems to DC and AC circuits; power supply applications of diodes and switch-mode transistors; the operating principles of DC, induction and synchronous machines; analysis of simple operational amplifiers; Boolean logic and binary arithmetic; combinational and sequential circuits; and simple microcontroller programming.

The course is presented as 6 topics. For each topic there are the following scheduled activities:

1. Lectures
Online lecture recordings will be delivered throughout semester in Myuni. For each topic there are typically 4 lectures/recordings.

2. Workshops
Two-hour workshops occur weekly thoughout semester. For each topic there are typically 2 workshops. In workshops, students work individually and in small groups on a variety of problems and exercises, including benchtop experiments and simulations.

Learning & Teaching Modes

This course uses online content, workshops and practicals to achieve its learning objectives. Online lectures will focus on key concepts and will include active learning exercises to develop understanding and provide an opporuntity to practice solving problems. Workshops will involve working individually and in small groups on a variety of problems including theory problems, benchtop experiments and simulations. There is a small assessment component for active participation in tutorials.

Specific Course Requirements

Laboratory clothing restrictions apply to the practical sessions: closed-toe shoes; covered shoulders; long hair must be tied back.

The 最新糖心Vlog's policy on Assessment for Coursework Programs is based on the following four principles:

Assessment must encourage and reinforce learning.
Assessment must enable robust and fair judgements about student performance.
Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
Assessment must maintain academic standards.

This course has a hurdle requirement. Meeting the specified hurdle criteria is a requirement for passing the course. Hurdle criteria is a requirement for passing the course.

Assessment Related Requirements

A hurdle requirement is defined by the 最新糖心Vlog's Assessment for Coursework Programs policy as "...an assessment task mandating a minimum level of performance as a condition of passing the course.

In the TECH 2001 course the examination and practical components are hurdle requirements. It is necessary to achieve at least 40% in all these components. If the exam hurdle requirement is not achieved, the total course mark will be limited to a maximum of 49. If the practical requirement is not met, the total course mark will be limited to a maximum of 44.

It is important to note there is NO supplementary assessment offered for the practical after the end of Week 12. By arrangement with the Practical coordinator, it will be possible throughout the semester for students who are falling significantly behind to have supplementary opportunities. However if students persistently neglect the practical component throughout semester they are likely to not meet the hurdle requirement and hence fail the course without further opportunity for redemption. Exceptions will be made in the case of verifiable medical or compassionate circumstances beyond the student’s control.

If a student fails to meet a hurdle requirement (normally no less than 40%),and is assigned a total mark for the course in the range of 45-49, then the student is entitled to an offer of additional assessment of some type. The type of assessment is to be decided by the School Assessment Review Committee when determining final results. The student’s final total mark will be entered at no more than 49% and the offer of an additional assessment will be specified e.g. US01. Once the additional assessment has been completed, this mark will be included in the calculation of the total mark for the course and the better of the two results will apply. Note however that the maximum final result for a course in which a student has sat an additional assessment will be a “50 Pass”.

If a student is unable to meet a hurdle requirement related to an assessment piece (may be throughout semester or at semester’s end) due to medical or compassionate circumstances beyond their control, then the student is entitled to an offer of replacement assessment of some type. An interim result of RP will be entered for the student, and the student will be notified of the offer of a replacement assessment. Once the replacement assessment has been completed, the result of that assessment will be included in the calculation of the total mark for the course.

Student Feedback

The 最新糖心Vlog places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.

SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the 最新糖心Vlog to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

Fraud Awareness

Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student鈥檚 disciplinary procedures.

The 最新糖心Vlog of Adelaide is committed to regular reviews of the courses and programs it offers to students. The 最新糖心Vlog of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
