Assessment summary

Below are brief assessment details. Further information can be found in the Canvas site for this unit.

Assignments

There are two assignments, each consisting of several questions. The assignments are designed to help you develop problem-solving skills, practice written answers and obtain some progressive feedback.

We encourage students to discuss assignments, but we will NOT accept assignments that are simply copied between students or from any other source. You should write your final answers independently, expressing the answers in your own words and with your own working. Allowing your work to be copied is unfair to other students and ultimately, does not help the student copying from your work.

AI systems like ChatGPT may seem to be an easy way of generating text that can be presented as your own in an Assignment. It is academically dishonest to use such AI systems and seek to present this as your own work. However, it may be useful to use AI to collect information about a topic as a first step towards writing your own answer, much as you might use Wikipedia.

The problem-based assignments typical of this unit are different to more essay-based assignments in other disciplines. References are generally NOT necessary unless you use a direct quote from a source. If you do reference a source, choose any style of referencing you normally use providing it is clear.

The Assignments contribute 20% directly to your final mark.

Pre-lecture Quizzes

Pre-lecture quizzes will consist of several questions delivered on-line using the Canvas system. They are intended to encourage you to prepare for lectures by reading the textbook and any notes we supply and test your understanding of material to be covered in the lectures in the coming week. Answers will be apparent from the relevant sections of the reading. You do not need to get every answer right, but only a serious attempt at a quiz will be regarded as satisfactory completion of the quiz.

The Pre-lecture quizzes contribute 5% directly to your final mark.

Workshop Tutorials

Workshop Tutorials are an important part of success in this Unit of Study because they make you think through the material and provide experience in answering the style of questions that may appear in the Final Exam.

Workshop Tutorials are not assessed and do not contribute to your final mark.

Studio Lab Sessions

Assessment in the studio lab sessions is based on successful completion of experimental and simulation tasks and other activities conducted in the sessions. You are awarded marks for satisfactorily completing each activity and and submitting the results.

The Studio Lab submissions contribute 25% directly to your final mark.

Final Examination

A two-hour examination covering the material included in the unit of study is held at the end of the semester. You will be asked to write descriptive answers to questions, to explain physical principles and to answer quantitative questions, all aimed at demonstrating your progress in achieving the goals of the unit. An ability to memorise formulae and manipulate them without understanding the associated concepts will not be rewarded. The final exam will cover material from the entire unit.

See the Sample Exam papers in the Canvas pages for this unit for an accurate indication of the exam structure.

The Final Examination contributes 50% directly to your final mark.

Note that attempting the final examination is required for a pass in this unit.

If you miss the final exam for any reason you should submit an application for Special Consideration to request a replacement exam in the same format.

If a second replacement exam is required, this exam may be delivered via an alternative assessment method, such as a viva voce (oral exam). The alternative assessment will meet the same learning outcomes as the original exam. The format of the alternative assessment will be determined by the unit coordinator.

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

Result name	Mark range	Description
High distinction	85 - 100	Representing complete or close to complete mastery of the material.
Distinction	75 - 84	Representing excellence, but less than complete mastery.
Credit	65 - 74	Representing a creditable performance that goes beyond routine knowledge and understanding, but less than excellence.
Pass	50 - 64	Representing at least routine knowledge and understanding over a spectrum of topics and important ideas and concepts in the course.
Fail	0 - 49	When you don’t meet the learning outcomes of the unit to a satisfactory standard.

The grading system used in this unit of study has changed from previous semesters to be a simple addition of various assessment components.

Your final grade will be based principally on your performance in one examination-style assessment where you are clearly working by yourself:

final exam (50%)

Other contributions to your final mark are:

assignment 1 (10%)
assignment 2 (10%)
studio lab submissions (25%)
pre-lecture quizzes (5%)

For example:

If you were not fully engaged during semester, you might complete only 7/11 of the pre-lecture quizzes and get a mark of 22/45 for the Studio labs. These might be added to better marks of 45/60 in the assignments and 44/70 in the final exam. Of course, if you have a valid reason for missing any assessment which is approved via the Special Consideration process, your marks will be adjusted to allow for this.

Your total mark is the sum of these weighted according to the percentages give above – i.e. final exam (31.4/50%) + assignments (15/20%) + studio labs (12.2/25%) + pre-lecture quizzes (3.2/5%) = a final mark of 61.8 = a final grade of 62 PS.

Of course a poor mark in the final exam could easily turn this into a Fail! The way to succeed in this unit is to do well in each component of the unit (as always) and to complete most (preferably all) of the assessments during semester.

For more information see guide to grades.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

Deduction of 5% of the maximum mark for each calendar day after the due date.
After ten calendar days late, a mark of zero will be awarded.

This unit has an exception to the standard University policy or supplementary information has been provided by the unit coordinator. This information is displayed below:

As an example, on an assignment given a mark of 7/10, the penalty would be 0.5 marks if submitted up to 24 hours late, resulting in a final mark of 6.5/10. If the assignment is submitted 6 days late, the penalty would be 3 marks and the final mark would be 4/10. If you have difficulty submitting an assessment on time, you should submit an application for Special Consideration. A Simple Extension of up to five working days on Assignments and Studio Lab submissions is also available through the special consideration portal, or for Quizzes may be negotiated with the unit coordinator. However, in this unit, negotiated Simple Extensions will only rarely be granted since justifiable reasons for extension should usually be eligible for Special Consideration.

Academic integrity

The Current Student website provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

Use of generative artificial intelligence (AI) and automated writing tools

You may only use generative AI and automated writing tools in assessment tasks if you are permitted to by your unit coordinator. If you do use these tools, you must acknowledge this in your work, either in a footnote or an acknowledgement section. The assessment instructions or unit outline will give guidance of the types of tools that are permitted and how the tools should be used.

Your final submitted work must be your own, original work. You must acknowledge any use of generative AI tools that have been used in the assessment, and any material that forms part of your submission must be appropriately referenced. For guidance on how to acknowledge the use of AI, please refer to the AI in Education Canvas site.

The unapproved use of these tools or unacknowledged use will be considered a breach of the Academic Integrity Policy and penalties may apply.

Studiosity is permitted unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission as detailed on the Learning Hub’s Canvas page.

Outside assessment tasks, generative AI tools may be used to support your learning. The AI in Education Canvas site contains a number of productive ways that students are using AI to improve their learning.

Learning support

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.
