  • Learning & Teaching Activities
    Learning & Teaching Modes

    The course material is delivered through weekly lectures and small-group tutorials. The lectures cover various topics of stress analysis and design, with a focus on the fundamental theoretical concepts and their practical applications in the real world. The small-group tutorials focus on the development of problem solving and communication skills in the context of the design of simple structural and machine elements.

    Workload

    The information below is provided as a guide to assist students in engaging appropriately with the course requirements.

    The workload for the course comprises of lecture, tutorial and laboratory attendance as well as completing several formative and summative assessment tasks throughout the semester. The formative assessments comprise of multiple-choice quizzes conducted during the lectures and practice problems solved by students during the tutorials. The summative assessment comprises of assignments, classroom tests, laboratories and an open-book exam.

    The assignments cover problems which are more advanced than the problems discussed in lectures and tutorials. The assignment problems are aimed at challenging the students intellectually and providing stimulus for students to extend their conceptual understanding in a self-directed manner.

    Three classroom tests will be conducted during the semester to develop time management and problem solving skills. It is hoped that the multiple tests will provide students an opportunity for self-assessment and improvement.
     
    The laboratories are intended to provide students with practical experience in using experimental techniques, such as Digital Image Correlation, and numerical analysis using the Finite Element Method. The laboratories also provide students with the experience in report writing and communication.

    The examination is intended to assess the student’s knowledge and understanding of the various topics covered in the course.

  • 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.

  • 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.
