Methods of Teaching / Learning

Formal lectures and occasional large group tutorial/question sessions. Teaching given by handouts, data projector and white board presentations and notes.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate their knowledge of concepts behind Radiation Physics.

Thus, the summative assessment for this module consists of:



A 1.5 hour duration examination paper that consists of 5 questions on Radiation Physics. Students will be asked to answer 3 questions from the 5. Full marks in the examination will be equivalent to 70 % of the total marks available in assessment of this module.


A take home written coursework test will be given in Week 7 which will be handed in one week later. This will make up 30% of the final module mark.



 

Formative assessment and feedback

Students will receive feedback on their performance in the take home written coursework test, each test being marked.
