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 (IKO1-7). 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 (ISO1-8).

Project which is mainly based on development of a design and analysis programme, will provide a platform for active participation to exercise cognitive skills, planning, problem solving, numeracy skills and computer literacy (ISO1 - 5).

The Computer 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 provides the students with the opportunity to develop systematic scientific methods under time-limited conditions.

Assessment Methods

Assessment Rationale And Relationship

The examination affords 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 coursework provides students with an opportunity to demonstrate written, planning and organising, problem solving, technical presentation, creativity and innovation, numeracy and computer literacy and associated cognitive skills. Feedback on the coursework will be an on-going and step by step exercise at almost every lecture or tutorial. The Graduate Skills Framework entries indicated as 'A' are also assessed in this way.
