    Learning Activities Summary
    The course will explore the following topics:

    • Expansive Soils
      • Characteristics of Expansive Soils
      • Design of Residential Footings on Expansive Soils
      • Assessment and Rehabilitation of Cracked Structures

  • 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.

    * The specific due date for each assessment task will be available on MyUni. The assignment is due two weeks after having attended the laboratory session.

    This assessment breakdown is registered as an exemption to the University's Assessment for Coursework Programs Policy. The exemption is related to the Procedures clause(s): 1. a. i 1. c.
    Assessment Related Requirements
    Assignments 1 and 2 will be undertaken in pairs and students will submit a joint report. Students will be permitted to choose their partner on MyUni.

    For Assignment 2, the commercial software SLOG will be used to assist in the design of the residential footing founded on expansive soil. The software will be made available to students and will be demonstrated in lectures.

    Assignment 3 will be undertaken individually.

    Requests for exemption from coursework components will only be considered when presented on an Exemption from Attendance Form. All exemption requests must be made by the end of Week 3 of Semester. Exemptions will not be considered for exams.

    This course includes peer assessment for the tasks undertaken within groups. Further detail of the peer assessment is contained on
    MyUni.

    To maintain the integrity of the assessment tasks there is a requirement that all students within a group contribute to each assessment task. Where there is evidence that group members have not sufficiently contributed to a group assessment task, the Academic Honesty policy may be applied.

  • 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.
