  • Assessment

    The University's policy on Assessment for Coursework Programs is based on the following four principles:

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

    Assessment Related Requirements

    Compulsory attendance at FE tutorials and Lab classes, minimum result required for FE and Lab classes is 50%.

    Assessment Detail

    Solid Mechanics part

    Assignments 1 - 3

    There are problem-solving exercises. These problems will be discussed in class in detail before the due date. Example problems with full worked solutions will be considered in class and the solutions of the assignment’s problem will be available on MyUni.

    FE Tutorials Report

    This is an individually written assignment on the FE modelling part of the course and will involve problem-solving exercises. The timetable for FE tutorials will be available on MyUni in the beginning of semester.

    Lab Classes Report

    This is a group assignment on the experimental study part of the course. The timetable for the lab classes will be available on MyUni in the beginning of semester.

    Quizzes

    Quizzes are individual in-class assignments and this includes problem-solving exercises to be completed in normally 45 min with full worked solutions to be available on MyUni.

    Structural Design part

    All assessment tasks (except the final exam) require groupwork. The objective is to provide students with the experience of working in groups to undertake open-ended design tasks. These types of problems reflect the challenges presented to engineers in industry, whereby efficient designs must be supported by rigorous quality assurance strategies in order to mitigate risk. The truss design involves conceptual, preliminary and final design procedures. This is supported by the preparation of engineering calculations and drawings, along with the construction and testing of a model truss to determine the robustness of the design. The aim is to minimise the strength-to-weight ratio of the structure to maximise efficiency. The reinforced concrete design involves design calculations and an investigation into the multi-disciplinary aspects of the design and construction of a real-life building. All aspects of the course include quality assurance strategies including self and peer-checking, and verification.

    Submission

    Solid Mechanics part

    Quiz will be collected at the end of tutorial.

    All other assignments must be submitted as a hard copy accompanied by an assessment cover sheet available from S116 or near the assignment submission area. These must be placed the labelled box located on level 2 of Engineering South Building.

    Late assignments will be penalised 10% per day. Extensions for assignments and reports 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. 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.

    Structural Design part

    Assessment tasks (except the final exam) must be submitted as a hard copy accompanied by a signed assessment cover sheet. These must be placed in the labelled mail box adjacent to room N136, Engineering North (i.e. front office of the School of Civil, Environmental and Mining Engineering).

  • Student Feedback

    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.

  • Student Support
  • Policies & Guidelines
  • 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’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.
