Teaching Rationale And Relationship
The module will consist of lectures and tutorials which provide the easiest way for students to assimilate the knowledge content and define the scope of each of the syllabus topics (IKO1-6). In the tutorial sessions the students are provided with the opportunity to gain oral feedback from the lecturing staff.
The independent study time is essential for students to work through the lecture material, in their own time and at their own pace (ISO1-5).
The laboratory class provides an opportunity for practical application of some of the taught material. It develops practical skills and demonstrates the relevance of the taught material. In addition it highlights the differences between pure theory and practical application and provides the students with the opportunity to develop systematic scientific methods, including data collection, recording and data analysis under time-limited conditions.
The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship
Examinations afford students an opportunity to demonstrate knowledge, understanding and possession of subject specific and key skills. The medium also allows students to demonstrate intended learning outcomes across a wide range of topics within a syllabus under time-limited conditions, this being a valuable metric for any subsequent employer.
The exams also afford students an opportunity to demonstrate numeracy and literacy and associated cognitive skills. The practical experiment assesses their ability to perform a piece of work, including experimental measurements, calculations, interpretation and presentation, without a tight time limit. The Graduate Skills Framework entries indicated as 'A' are also assessed in this way.
Semester 1 Study Abroad students would be required to sit an alternative examination in the December examination period.
