PURE MTH 7072 - Fields and Modules

North Terrace Campus - Semester 2 - 2023

This subject presents the foundational material for the last of the basic algebraic structure pervading contemporary pure mathematics, namely fields and modules. The basic definitions and elementary results are given, followed by two important applications of the theory: to the classification of finitely generated abelian groups, and to Jordan canonical form for matrices. The subject concludes by returning to fields to present interesting applications of the theory. Fields: vector spaces, matrices, characteristic values: extension fields. Modules: finitely generated modules over a PID: canonical forms for matrices: Jordan canonical form. Applications of fields to algebraic and geometric problems.

    S. Lang, `Undergraduate Algebra' (available in the library as an e-book).
    Online Learning
    Assignments, tutorial exercises, handouts, and course announcements will be posted on MyUni.

  • Learning & Teaching Activities
    Learning & Teaching Modes
    The course will be taught as a sequence of topics and managed via My-Uni. 

    Each topic will be presented through a series of short topic videos, followed by quizzes to test student understanding and provide instantaneous feedback.  

    Each week a face-to-face active learning session will be offered together with a weekly face-to-face tutorial.

    Students are expected to engage with all material on My-Uni. 

    Fortnightly homework assignments help students strenghten their understanding of course material, and help them gauge their progress.

    A weekly consulting hour will be scheduled by arrangement with students prior to the start of the course

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

  • 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
    Assessment taskTask typeDueWeightingLearning outcomes
    Examination Summative Examination period 50% All
    Homework assignments Formative and summative Weeks 3, 5, 7, 9, 11 15% All
    Mid-semester Test Formative and summative Week 6 20% All
    Quizzes Formative and summative ongoing 10% All
    Participation Formative and summative ongoing 5% All
    It is anticipated that the examination will be invigilated and held at Wayville for students in Adelaide.  Alternative arrangements will be made for remote students.
    Assessment Related Requirements
    An aggregate score of 50% is required to pass the course.

    Each assignment will count for 3% of the final grade.  The participation grade will be determined by participation in tutorials and/or active participation in discussion. Online quizzes will be set on an ongoing basis. The mid-semester test will be held in Week 6.
    Homework assignments must be submitted on time with a signed assessment cover sheet. Late assignments will not be accepted. Assignments will be returned within two weeks. Students may be excused from an assignment for medical or compassionate reasons. Documentation is required and the lecturer must be notified as soon as possible.

  • 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.
