Learning & Teaching Activities
Learning & Teaching Modes
Lectures supported by problem-solving tutorials developing material covered in lectures
The information below is provided as a guide to assist students in engaging appropriately with the course requirements.
As per university recommendations, it is expected that students spend 48hrs/week during teaching periods, and that a 3 unit course has a minimum workload of 156 hours regardless of the length of the course. Additional time may need to be spent acquiring assumed knowledge, working on assessment during non-teaching periods, and preparing for and attending examinations.

Specific Course Requirements
The University'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.
All assessment tasks are summative. There are 4 assignments, all together worth 10% of the assessment, one group project report worth 20% of the assessment and an open book exam worth 70%. All assignments are due by 4pm on the due date. Details of each task are tabulated below.

Assessment Related Requirements
All the assignments are problem type questions. The solutions to the assignments will be reviewed and marked by the course tutor/s according to the marking rubric. The solutions will be available to the students on MyUni after the submission date. The group project will be marked based on 50% group mark and 50% individual contribution using a peer assessment method. The project assessment rubric is presented below:
Section/Criteria Mark (total 100) 1- External design /10 2- Weight calculation /5 3- Matching diagram /10 4- Configuration design /15 5- Drawings /20 6- Format and clarity /15 7- Research activities /10 8- Completeness /15
The hard copy of all assignments and project report must be submitted in the labelled box on level 2 of Engineering South Building. Any assignments submitted as a hard copy must be accompanied by an assessment cover sheet available from room S116 or near the assignment submission area. Late assignments will be penalised 10% per day. Extensions for all assignments will only be given in exceptional circumstances and a case for this with supporting documentation can be made in writing after a lecture or via email to the lecturer who set the assignment. Hard copy assignments will be assessed and returned in 2 weeks of the due date. There will be no opportunities for re-submission of work of unacceptable standard. Due to the large size of the class feedback on assignments will be limited to in-class discussion resulting from questions from students.
Grades for your performance in this course will be awarded in accordance with the following scheme:
M10 (Coursework Mark Scheme) Grade Mark Description FNS Fail No Submission F 1-49 Fail P 50-64 Pass C 65-74 Credit D 75-84 Distinction HD 85-100 High Distinction CN Continuing NFE No Formal Examination RP Result Pending
Further details of the grades/results can be obtained from Examinations.
Grade Descriptors are available which provide a general guide to the standard of work that is expected at each grade level. More information at Assessment for Coursework Programs.
Final results for this course will be made available through Access Adelaide.
The University 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 University 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.

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’s disciplinary procedures.
The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
