Teaching Methods

Please note that module leaders are reviewing the module teaching and assessment methods for Semester 2 modules, in light of the Covid-19 restrictions. There may also be a few further changes to Semester 1 modules. Final information will be available by the end of August 2020 in for Semester 1 modules and the end of October 2020 for Semester 2 modules.

Teaching Rationale And Relationship

The module will be delivered through present in-person lectures supported by tutorial sessions and structured guided online materials to support the students’ learning. The lectures and structured materials define the scope of each of the syllabus topics (IKO1-7) whilst the tutorials provide the opportunity for students to practice their analytical skills.

The independent study time is essential for students to work through the lecture material, in their own time and at their own pace (ISO1-7).

Should the public health situation require it, the PiP lectures and tutorials will be replaced by additional structured, nonsynchronous online materials supported by synchronous online tutorial sessions.

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. The Graduate Skills Framework entries indicated as 'A' are also assessed in this way.

Should the public health situation require it, the planned examination scheduled to be completed present-in-person will be replaced by an open book, online examination to be completed within a defined 24 hour period. The coursework would be unaffected by this.
