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.

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.

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 copied 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. To meet the standard for a pass in the unit you need to satisfactorily complete at least 8 out of 11 quizzes. Otherwise there will be a small mark penalty.

Workshop Tutorials

Contributing to Workshop Tutorials is an important part of success in this Unit of Study. We measure your contribution by collecting answer sheets. Only a serious attempt at a answer sheet will be regarded as satisfactory completion of the Tutorial. To meet the standard for a pass in the unit you need to satisfactorily complete at least 7 out of 9 Workshop Tutorials. Otherwise there will be a small mark penalty.

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 check points for satisfactorily completing each activity. To meet the standard for a pass in the unit you need to satisfactorily complete at least 7 out of 9 Studio Labs (14 out of 18 check points). Otherwise there will be a small mark penalty. Previous experience indicates that this is not difficult to achieve if you apply yourself during each session. Most students get all 18 check-points.

In-Semester Test

A 45 minute in-semester test on unit content from the first lecture module (Where do X-rays come from?) will be held in the studio lab session in Week 8. It is intended to give you experience of exam-style questions in exam conditions and give you some feedback on how your understanding of the course material is developing

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, including material tested in the mid-semester test, although the second half of the unit will have a slightly greater emphasis.

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

Note that you will need your own non-programmable calculator for the examination. See the University policy on calculators at https://sydney.edu.au/students/exams/approved-calculators.html

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.

For more information see sydney.edu.au/students/guide-to-grades.

The grading system used in this unit of study is somewhat different from that used in many other units. It is based on setting appropriate standards in different types of assessment. Your final grade will be based principally on your performance in the final exam, the in-semester test and assignments. However, ALL assessments are compulsory and have mark standards that must be achieved.

Your final grade will be based principally on your performance in the two examination-style assessments:

final exam (60%)
in-semester test (20%)

and assignments:

assignment 1 (10%)
assignment 2 (10%)

The minimum standard to achieve a pass mark in this unit is:

examinations + assignments = 50%

In addition you must meet satisfactory standards in the participation assessments:

pre-lecture quizzes
workshop tutorials
studio labs

If you do not meet these standards you will be penalised for each by 2% of the total mark.

Standards for achievement in the participation assessments are as follows:

	Quizzes (/11)	Tutorials (/9)	Studio Labs (/18)
Minimum Standard	8	7	14

For example:

If you did relatively poorly in the mid-semester test (7/20), but much better in the assignments (16/20) and final exam (53/60), your total mark would be 76. This is a Distinction (DI) standard. However, for this to be your final result, you would also need to achieve the minimum standard in ALL your participation assessments - i.e.

satisfactorily participated in at least 8/11 pre-lecture quizzes
satisfactorily participated in at least 7/9 tutorials
completed at least 14/18 checkpoints in the lab

Most Distinction students will achieve these standards easily as part of their conscientious work during the semester. However, if (for instance) you satisfactorily participated in only 9/11 quizzes, 6/9 tutorials and 13/18 lab checkpoints, you would not be penalised for quizzes, but would lose 2 marks for tutorials and 2 marks for lab. Your final result would then drop to 72 CR.

Of course, if you have a valid reason for missing an assessment which is approved via the Special Consideration process, your marks will be adjusted to allow for this.

The way to succeed in this unit is to do well in the various tests and assignments (as always) and to complete most (preferably all) of the participation assessment tasks.

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.

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.

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

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.

Attendance and class requirements

Due to the exceptional circumstances caused by the COVID-19 pandemic, attendance requirements for this unit of study have been amended. You will have chosen either on-campus enrolment (CC) or online/remote enrolment (RE).

All lectures are online for both CC and RE students.

Where on-campus tutorials/laboratories have been scheduled, CC students should make every effort to attend and participate at the scheduled time.

Where online tutorials/laboratories have been scheduled, RE students should make every effort to attend and participate at the scheduled time. Penalties will not be applied if technical issues, etc. prevent attendance at a specific online class. In that case, students should discuss the problem with the coordinator, and attend another session, if available.

In both cases student attendance will not be compulsory but participation as measured by submission of an assessment task is required.

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

Responding to student feedback

This section outlines changes made to this unit following staff and student reviews.

We welcome comments on all aspects of this unit. You should feel free to talk to your lecturers, tutors or the Unit Coordinator A/Prof. John O’Byrne at any time. There is also a formal opportunity for feedback via the USS questionnaire for this unit, available online towards the end of semester. As a result of student feedback and other initiatives there have been a number of changes in this unit recent years. This year we have reduced the number of assignments to two, resulting in a change to the allocation of assignment marks. There has also been a small change in the way in which engagement in Pre-lecture Quizzes, Workshop Tutorials and Studio Labs is counted towards your final mark, with the aim of making it easier to understand.
