Introduction to discrete mathematics and its use in mathematical modelling. Emphasis will be placed on developing facility, technique and use in applications. Modelling of processes and phenomena which occur in the physical, environmental and life sciences, especially computer science, will be used as a vehicle throughout. Topics to be covered include: logic and set theory, mathematical reasoning, combinatorics and counting, mathematical induction and recurrence relations, graph theory and networks, matrix arithmetic and Markov chains.

Learning Outcomes

Upon successful completion, students will have the knowledge and skills to:

1. Recall, invent, interpret examples of motivation for mathematical constructs used in discrete mathematics as models of processes in the world.
2. Recognise, define, explain and use terminology and notation from discrete mathematics.
3. Identify the logical structure of a statement, and then identify the logical structure of an argument that may be used to prove or disprove the statement.
4. Perform mathematical calculations in discrete mathematics using methods presented in the course.
5. Write simple proofs/construct explicit counterexamples for statements relating to discrete mathematics topics covered in the course.

Research-Led Teaching

Where appropriate, indication will be given of current research areas related to topics in the course.

Examination Material or equipment

In the final exam the permitted materials will include:

• A non-annotated translation dictionary (for ESL students).

Required Resources

Course Notes: PDF copies of all lecture slides will be made available on the course website, in addition to the ECHO lecture recordings.

Recommended Resources

Optional Text: Susanna Epp: Discrete Mathematics with Applications; 5th ed. Metric Edition, Cengage.

An e-book of this text is available to all students for free through the ANU Library https://anu.primo.exlibrisgroup.com/permalink/61ANU_INST/1csbe8o/cdi_askewsholts_vlebooks_9780357121467

References to this text will be provided for all course topics except the last (Random Walks).

The text does not cover every single subtopic in the course, and does cover some subtopics not required for the course, but is nonetheless a good match to the course in both level and content.

Recommended student system requirements 

ANU courses commonly use a number of online resources and activities including:

• video material, similar to YouTube, for lectures and other instruction
• two-way video conferencing for interactive learning
• email and other messaging tools for communication
• interactive web apps for formative and collaborative activities
• print and photo/scan for handwritten work
• home-based assessment.

To fully participate in ANU learning, students need:

• A computer or laptop. Mobile devices may work well but in some situations, a computer/laptop may be more appropriate.
• Webcam
• Speakers and a microphone (e.g. headset)
• Reliable, stable internet connection. Broadband recommended. If using a mobile network or wi-fi then check performance is adequate.
• Suitable location with minimal interruptions and adequate privacy for classes and assessments.
• Printing, and photo/scanning equipment

Staff Feedback

Students will be given feedback in the following forms in this course:

• Workshops: Demonstrators will give individual guidance and correction to student work on, and presentation of, worksheet problems.
• Homework Assignments (including the Midsemester Assignment): Demonstrators will grade assignment work. Brief indications of where and how errors have been made will be provided with each student’s work, either in written or audio form. Common errors may be briefly discussed with the whole class during workshops. Students will then have an opportunity to ask the demonstrator about other errors.
• Final exam: Students will have an opportunity to view their exam scripts, view official solutions and rubrics, and ask the convener about any grading issues using a grade appeal process.

Student Feedback

ANU is committed to the demonstration of educational excellence and regularly seeks feedback from students. Students are encouraged to offer feedback directly to their Course Convener or through their College and Course representatives (if applicable). The feedback given in these surveys is anonymous and provides the Colleges, University Education Committee and Academic Board with opportunities to recognise excellent teaching, and opportunities for improvement. The Surveys and Evaluation website provides more information on student surveys at ANU and reports on the feedback provided on ANU courses.

Other Information

It is intended that all lectures will be delivered in-person on-campus for those who can attend on-campus events. Lectures are recorded, and the recordings are made available via Wattle shortly after the lecture. Workshops are delivered in-person on-campus and are not recorded.

Finally, please also note that, as with all courses at ANU, a moderation process takes place after the marks for the various assessment components of the course are aggregated. Moderation is to provide consistency of grade standards across years and courses. It may result in the scaling up or scaling down, of your raw total score.

Policies

ANU has educational policies, procedures and guidelines, which are designed to ensure that staff and students are aware of the University’s academic standards, and implement them. Students are expected to have read the Academic Misconduct Rule before the commencement of their course. Other key policies and guidelines include:

• Student Assessment (Coursework) Policy and Procedure
• Special Assessment Consideration Policy and General Information
• Student Surveys and Evaluations
• Deferred Examinations
• Student Complaint Resolution Policy and Procedure

Assessment Requirements

The ANU is using Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. For additional information regarding Turnitin please visit the ANU Online website Students may choose not to submit assessment items through Turnitin. In this instance you will be required to submit, alongside the assessment item itself, hard copies of all references included in the assessment item.

Moderation of Assessment

Marks that are allocated during Semester are to be considered provisional until formalised by the College examiners meeting at the end of each Semester. If appropriate, some moderation of marks might be applied prior to final results being released.

Participation

Although there are no participation requirements (hurdles) for this course please note that:

You must attend the workshop in which you are enrolled to participate in the workshop and to take the workshop quiz. Quiz scores and workshop participation contribute to your final grade. Details of how this is assessed are given in the details of this assessment item stated elsewhere in this document.

Assessable material for the course is specified by lecture content (rather than any text). So it is important to keep up regular monitoring of lectures, preferably by attending but otherwise by accessing the lecture recordings and/or PDF notes on Wattle.

Examination(s)

This course includes a final examination. The details and mode of delivery for exams will be communicated through the course Wattle site and the ANU examination timetable.

Assessment Task 1

Workshop Quizzes (best 8 of 10)

At the start of each workshop, you will complete a very short quiz, primarily on the material from lectures in the week preceding the quiz (the quiz in week x will primarily address material covered in lectures during week x-1). A typical quiz question will ask you to demonstrate your ability to recall or invent examples to illustrate ideas and motivations (LO1), your proficiency with the ideas, vocabulary and notation of the material (LO2), or your ability to recognize the logical structure of an argument or to describe the logical structure of an argument that may be used to prove a given statement (LO3). Given the nature of the problems, no partial credit will be given on quizzes. Your scores on each problem will be used to assign a score out of 1 for each quiz. To allow for occasional absences, the quiz contribution to your final grade will be calculated from your best eight (out of ten) quiz marks.

Assessment Task 2

Participation in Workshops ( best 8 of 10)

Workshops run in teaching weeks 2, 3, 4, 5, 6 and 8, 9, 10, 11, 12. You should attend one workshop, at the same time, each week. You can select from available workshop times as described on the course Wattle page.

A worksheet will be made available on Wattle for each workshop. You will be expected to access a copy of the worksheet in the workshop (so bring a printout or a device to access the pdf). In the workshop you will be encouraged to work collaboratively on the worksheet questions, asking for help from the demonstrator as needed. You may also be asked to present solutions to the class. The aim is to give you an opportunity to practice and improve your skill in verbal communication of mathematics, and to give the demonstrator an opportunity to correct any misconceptions that you or other class members may have about the underlying theory.

For each workshop, a participation score of up to 1 point will be determined by your demonstrator and recorded in Wattle. You earn this point by participating throughout the workshop with energy and enthusiasm. No partial credit will be given. At the end of the semester, your scores will be combined to compute the workshop participation contribution to your final grade. To allow for occasional absences, your workshop participation contribution to your final grade will be calculated from your best eight (out of ten) workshop marks.

Please note that this grading scheme makes no mention of "correct solutions"; rather, it is your energy and commitment to making the most of the learning opportunities that are rewarded. Workshops are formative tasks, meaning we expect that the workshops help you master the material.

Each workshop is 90 minutes long; the 30 minutes following the end of the scheduled workshop time is an optional consultation session for students to ask questions after their workshop has ended.

Assessment Task 3

Written Assignment 1

This written assignment is due by 16:00 on the Monday of teaching week 6. It assesses material covered in lectures in weeks 1, 2, 3 and 4.

Answer types range over requiring examples (LO1), selecting correct terminology (LO2), interpreting and creating diagrams and expressions (LO1, 2, 4), calculating various values and expressions from given data (LO4), identifying the logical structure of a statement, and then identifying the logical structure of an argument that may be used to prove or disprove the statement (LO3) and, creating justifications or proofs of statements (LO5).

The assignments will be made available on the course website (Wattle) as early as possible, and at least three weeks before it is due. The completed assignment must be scanned and uploaded to Wattle before the deadline. Late assignments will not be accepted. It is intended that you will be able to view your grade with brief feedback within a week of the submission deadline.

Assessment Task 4

"Mock Mid-Semester Exam" Assignment

This assignment is in the form of a mock exam that covers the material from the first six weeks of lectures. It is intended to take 120 minutes to complete. It will be released at 10:00 on the Monday of teaching week 7 and must be submitted by 16:00 on the Friday of teaching week 7. Please note that there will be no workshops or weekly assignments in teaching week 7, and this is to allow you to spend time on this assignment. The completed assignment must be scanned and uploaded to Wattle before the deadline. Late assignments will not be accepted. It is intended that you will be able to view your grade with brief feedback within a week of the submission deadline.

Assessment Task 5

Written Assignment 2

This written assignment is due by 16:00 on the Monday of teaching week 12. It assesses material covered in lectures in weeks 1 through 10 (inclusive), with a primary focus on the material covered in weeks 7, 8, 9 and 10.

Answer types range over requiring examples (LO1), selecting correct terminology (LO2), interpreting and creating diagrams and expressions (LO1, 2, 4), calculating various values and expressions from given data (LO4), identifying the logical structure of a statement, and then identifying the logical structure of an argument that may be used to prove or disprove the statement (LO3) and, creating justifications or proofs of statements (LO5).

The assignments will be made available on the course website (Wattle) as early as possible, and at least three weeks before it is due. The completed assignment must be scanned and uploaded to Wattle before the deadline. Late assignments will not be accepted. It is intended that you will be able to view your grade with brief feedback within a week of the submission deadline.

Assessment Task 6

Final Examination

The final examination will be an in-person exam with 15 minutes of reading time followed by 180 minutes of writing time. The entire course will be examinable. The exam will be held during the ANU final examination period at a time and date determined by the ANU Examinations Office. Please check the course Wattle site and the ANU Examination Timetable to confirm the date, time, and location of the exam.

Regardless of performance on other assessment items, a minimum scaled score of 35% on the final exam is required to pass the course. (This is known as a 'course hurdle'.)

A sample exam, plus solutions, will be available on Wattle.

Some scaling of marks on the final exam may occur if the distribution of marks leads to results significantly out of line with previous years.

It is intended that results will be released electronically on the date that course results are published, as specified by the ANU academic calendar.

Academic Integrity

Academic integrity is a core part of our culture as a community of scholars. At its heart, academic integrity is about behaving ethically. This means that all members of the community commit to honest and responsible scholarly practice and to upholding these values with respect and fairness. The Australian National University commits to embedding the values of academic integrity in our teaching and learning. We ensure that all members of our community understand how to engage in academic work in ways that are consistent with, and actively support academic integrity. The ANU expects staff and students to uphold high standards of academic integrity and act ethically and honestly, to ensure the quality and value of the qualification that you will graduate with. The University has policies and procedures in place to promote academic integrity and manage academic misconduct. Visit the following Academic honesty & plagiarism website for more information about academic integrity and what the ANU considers academic misconduct. The ANU offers a number of services to assist students with their assignments, examinations, and other learning activities. The Academic Skills and Learning Centre offers a number of workshops and seminars that you may find useful for your studies.

Online Submission

You will be required to agree to a declaration as part of the submission of your assignments, that will record your understanding of ANU academic integrity principles. You should keep a copy of both your completed document and its pdf file. Note that pdf is the only file format permitted for online submission in MATH1005. MATH1005 does not use Turnitin, having been granted an exemption.

Hardcopy Submission

Except under very special course-wide conditions (e.g. major breakdown of the Wattle system) hardcopy submission of assignments will not be permitted in MATH1005.

Late Submission

Except in the case that an extension has been granted, late assignments will not be accepted. An assignment not submitted by the due date and time, and without an extension, will generally be awarded a mark of zero. Unless an extension has been granted, Wattle will not allow late submissions. In particular, extensions will not be granted to cover timing misjudgements. You need to leave enough time to scan and upload your document, remembering to allow time for possible mishaps in the process.

Referencing Requirements

Accepted academic practice for referencing sources that you use in presentations can be found via the links on the Wattle site, under the file named “ANU and College Policies, Program Information, Student Support Services and Assessment”. Alternatively, you can seek help through the Students Learning Development website.

Returning Assignments

Except in exceptional circumstances, you will be able to view your marked assignment via Wattle within a week of the due date. Exceptions include, but are not restricted to, unexpected unavailability of the marker and disruptions to the timetable resulting from public holidays.

Extensions and Penalties

Extensions and late submission of assessment pieces are covered by the Student Assessment (Coursework) Policy and Procedure The Course Convener may grant extensions for assessment pieces that are not examinations or take-home examinations. If you need an extension, you must request an extension in writing on or before the due date. If you have documented and appropriate medical evidence that demonstrates you were not able to request an extension on or before the due date, you may be able to request it after the due date.

Resubmission of Assignments

Assignments cannot be resubmitted.

Privacy Notice

The ANU has made a number of third party, online, databases available for students to use. Use of each online database is conditional on student end users first agreeing to the database licensor’s terms of service and/or privacy policy. Students should read these carefully. In some cases student end users will be required to register an account with the database licensor and submit personal information, including their: first name; last name; ANU email address; and other information. In cases where student end users are asked to submit ‘content’ to a database, such as an assignment or short answers, the database licensor may only use the student’s ‘content’ in accordance with the terms of service — including any (copyright) licence the student grants to the database licensor. Any personal information or content a student submits may be stored by the licensor, potentially offshore, and will be used to process the database service in accordance with the licensors terms of service and/or privacy policy. If any student chooses not to agree to the database licensor’s terms of service or privacy policy, the student will not be able to access and use the database. In these circumstances students should contact their lecturer to enquire about alternative arrangements that are available.

Distribution of grades policy

Academic Quality Assurance Committee monitors the performance of students, including attrition, further study and employment rates and grade distribution, and College reports on quality assurance processes for assessment activities, including alignment with national and international disciplinary and interdisciplinary standards, as well as qualification type learning outcomes.
