Learning and Teaching
Teaching and learning methods
The content of this module is delivered through lectures, module website, directed reading and tutorials.
Students work on their understanding through a combination of independent study, preparation for timetabled activities, tutorials and problem classes, along with formative assessments in the form of coursework assignments.
Students work on their practical skills, professional skills and technical understanding in technical and assessed laboratories.

Assessment
Assessment strategy
This module is assessed by a combination of coursework, assessed laboratories and a final assessment in the form of a written examination.
The Laboratory assessment which covers practical Learning Outcomes is assessed in the Laboratory Programme Module which includes in-semester opportunities for redeeming failure. These marks are carried forward to the Supplementary Assessment period or External Repeat.
Summative
This is how we’ll formally assess what you have learned in this module.
| Method | Percentage contribution |
|---|---|
| Laboratory | 20% |
| Examination | 70% |
| Coursework assignment(s) | 10% |
Referral
This is how we’ll assess you if you don’t meet the criteria to pass this module.
| Method | Percentage contribution |
|---|---|
| Examination | 80% |
| Lab Marks carried forward | 20% |
Repeat
An internal repeat is where you take all of your modules again, including any you passed. An external repeat is where you only re-take the modules you failed.
