    Learning & Teaching Modes

    This course uses a number of different teaching and learning approaches (in a set of integrated learning activities) including:

    · Lectures (usually two or three 1 hour lectures weekly)
    · Problem Solving Tutorials (six to eight throughout the semester)
    · Design sessions - computer suites (aproximately 13 hours design/computer suite sessions during the semester)
    · Lecture Participation
    · Examinations

    The lectures are supported and reinforced by the additional teaching modes including tutorials and designs (both formal and informal activities).

  • 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

    Expected Course Workload


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

    Please note that University guidelines suggest that the average student should spend 48 hours per week to achieve a Credit.

    Consequently, the total workload for this course is 12 hours per week (144 hours in total over 12 weeks) for an average student to achieve a Credit.


    Group Work

    For assessment tasks requiring group work, groups will be partly self selected (for assignments only). Allocation of numbers of students per group will depend on total number of students in the course in a particular year. If there are 4 members per group the following process will be followed. You will pair up with one other person with whom you will work in group work for the entire semester. Pairs will rotate to form a new group of four for each new group work task. All members in a group are expected to contribute equally to the overall task. In cases of perceived unequal contributions to group work, students should come and discuss the matter with the teaching staff. 

    Peer Assessment

    This course includes a peer assessment for the design tasks undertaken within groups.

    Hurdle Requirements

    In order to pass this course, students must obtain at least:
       
    40% for the exam

    If the above requirements are not met, students will receive a 39 F (fail) for this course OR the weighted mark for the course (whichever is lower mark).

    Please be aware that you may be eligible for an academic supplementary exam if you fail to meet this requirement. If a student sits a supplementary exam on academic grounds, the final mark will be based on that examination only. Failure to demonstrate a necessary level of knowledge and understanding of the course material in the supplementary exam will result in a fail grade.




    Assessment Detail

    A. Designs

    Objectives: The objective of the Designs is to provide students with the opportunity to apply the course material in a realistic context in order to achieve higher-order learning outcomes. 
     
    There will 3 components to the design including Design 1 (a) numerical methods for solving pipe network equations Design 2 (a) manual trial-and error design of a water distribution system using computer simulation and (b) genetic algorithm optimisation of a water distribution system using a computer software program called “Optimizer ” developed by an Adelaide company called Optimatics Pty Ltd.
                

    B. Assignments

    Objectives: The objective of the Assignments is to provide students with the opportunity to apply the course material to problems. 
     
    There will be a number of assignments - while working individually or in groups of four (sometimes 3 or 4 if necessary).


    C. Examination

    Objectives: The objective of an Exam is to provide an independent test of whether students have gained an understanding of the key learning objectives.  Details of which course learning objectives are addressed by the Exam are given above.
     
    A 3 hour examination will be held at the end of Semester I. It will be a restricted open book exam.

    ·       Notes provided by Prof Simpson for the course may be brought into the examination. This is explicitly restricted to the textbook by
    Crowe and Prof Simpson's book and Powerpoints of material not in Prof. Simpson's book.

    ·       NO OTHER BOOKS OR MATERIAL may be brought into the examination. Information relating to Fluid Properties will be permitted.

    ·       The design, tutorial solutions and worked problems including solutions to old examination problems, may NOT BE brought into the examination. A check of the material brought in by each student will be made at the beginning of the examination.

    ·       Use of dictionaries is permitted.

    .       The use of calculators is permitted. Ensuring the calculator batteries are sufficient for the duration of the examination is the responsibility of the student. 

    Supplementary exams awarded on academic grounds will only be given in extraordinary circumstances.
    If a student sits for a supplementary exam on academic grounds, the final mark will be based on the examination only.

    Submission
    Submission deadlines will be given on each assignment and on the lecture and tutorial schedule.

    Details about the submission process for the Homework Exercises will be given at the beginning of the semester and details of the submission process for the Designs will be given in separate handouts.


    _____________________________________________________________________________________________________________

    All submissions should be accompanied by a signed assessment cover sheet - available at:

    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.

  • 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.
