    Specific Course Requirements
    Not applicable.
  • 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 Summary
    Breakdown of the assessment tasks is shown in the table below.

    Assessment Tasks Weighting Submission Due Date Learning Outcomes
    Assignments (×5 sets, formative) 15% Individual 1 week after being assigned 1-8
    Practicals (×3 sets, formative) 15% Group 2 weeks after session 9-10
    Final Examination (summative) 70% Individual 3 hour duration, closed book 1-10
    Sub-Total 100%
    Bonus quizzes (×7 sets,
    formative)
    3.5 marks* Individual Flexible and before final exam 1-10
    Note: no hurdle requirement.
    *: read the details about 3.5 conditional marks which are shown below and under ‘Bonus quizzes’.

    Assignments
    There will be assignments set on each main lecture topic (5 in total) throughout the course.  These will typically consist of 2 problems per assignment and will be submitted, marked and returned regularly throughout the semester. Each assignment will be released at the end of relevant lecture topics, and then completed and submitted in 1 week.

    Practicals
    There are 3 compulsory practicals: soil gradation by sieve analysis, soil Atterberg limits, and soil compaction.  The practicals will be conducted in groups (4 students a group).  Groups are automatically assigned in terms of your session enrolment.  Should you have a need to be assigned together with your friend(s), make sure: 1) before Week 1, you have enrolled yourselves together with your friend(s) into the same session or at least sessions of the same time slot on the Course Planner, and 2) no later than the end of Week 1, you have emailed me all your names and the session number.  Requesting to pair students of different time slots would not be approved.

    Practical reports will be submitted as a group report – one submission per group and within 2 weeks after the practical session.  The due date for reports which are due in semester break will be extended to the weeks after, i.e., practicals conducted in weeks 7 and 8, respectively, due on the same day in weeks 9 and 10.  The practical schedule, group allocations and practical data are available on MyUni. Students are expected to read the practical on-line learning modules prior to attending the laboratory sessions.  The modules are available on Myuni and under the practicals tab.

    There will be no ‘make-up’ laboratory sessions for students who miss their scheduled session.  Students who miss a laboratory class due to medical or extenuating circumstances should present a medical certificate to the Course Coordinator or Practical Coordinator, and endeavour to reschedule into an active session.  Students who miss practicals will have up to 50% marks deducted.

    When writing up a practical report, include on the report only the names of the students who attended your session.

    Final Examination
    The final examination will cover all the materials covered during the semester.  The examination will be 3-hours and conducted under closed book conditions.  Sheets of formulae and charts will be attached as informative tools at the end of an examination book.  Supplementary or replacement exams will be awarded in accordance with the University policies.

    Bonus quizzes
    There are 7 sets of optional online quizzes, one set for each lecture series (chapter).  Each set of quiz comprises of 10 questions (e.g. multiple choice, true/false, matching, and fill in blanks), 1 point per each question and thus 10 points for each set of quiz.  

    The quizzes provide chances of gaining additional marks toward course final results.  A set of quiz contributes up to 0.5 conditional bonus mark to the final results, and thus a total of up to 3.5 conditional bonus marks is possible out of the 7 sets of quizzes.  

    The quiz marks are conditional in that: 1) a grade of 10 points in a quiz is equivalent to 0.5 bonus mark, and pro rate; 2) the final bonus mark will not effect the course final mark above 85%.  For instance, the combination of a weighed (assignments, pracs and final exam) mark of 83 and a final bonus mark of 3.0 simply results in 85% as a final course mark.  Additional instances of combination are shown in the table below.  Rounding will be applied for the real final course marks.

    Weighted mark (assignments, pracs and final exam) Final bonus mark

    70 3.3 73.3 C
    65 2.8 67.8 C
    47 3.0 50 P
    The quizzes are accessible on MyUni and from the ‘Online quizzes’ tab of this course webpage.  Up to ten attempts are allowed.  The average point of graded attempts is updated immediately after the attempts and viewable in My Grades of MyUni.  Extra attempts could be requested via emails to the Coordinator, which would be averaged as well.

    The calculation of the final bonus mark is demonstrated in the table below.

    Assessment Detail
    Further details of each assignment will be provided in lectures and via MyUni well before the due date.
    Submission
    E-Submission has been introduced for this course.  Assignments and practical reports must be submitted in electronic form (.pdf, .doc or .jpg) online through respective portals designed for this course on MyUni.  Hard copies dropped into the School’s submission box will not be collected nor graded.  The e-submission must be submitted before 5pm of the nominated due date (i.e., one week after assignment releasing and two weeks after a practical date).  

    Late submissions will be penalised at the rate of 5% per day.  No credit will be given for assignments uploaded after they have been marked and returned to the class.  A late submission will only be allowed when a deferred deadline has been approved by the Course Coordinator prior to the due date because of medical or extenuating circumstances (proof i.e. a medical certificate should be presented).  Any requests for extensions must be communicated by emails.

  • 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.
