Teaching Rationale And Relationship
The module will consist of recorded and present-in person (PiP) lectures with accompanying slides and tutorials sheets, provided to support guided learning. This provides an easy and accessible way for students to assimilate the knowledge content and define the scope of each of the syllabus topics (IKO1-6). Of the structured guided learning contact time, a blended approach in a 50:50 proportion of online and present-in-person (PiP) is used to facilitate an accessible and inclusive learning approach making full use of the advantages of both delivery formats. There are some online sessions for students to meet with lecturer and ask questions & get feedback. Face-to-face Present-in-person (PiP) class room sessions are used to discuss the taught material and go through worked examples and case-studies. If PiP activities cannot go ahead this can be replaced with a blend of Synchronous Online (SO) sessions and a greater emphasis on non-synchronous online materials.
The independent study time is essential for students to work through the lecture material, supported with reading and tutorial question practice in their own time and at their own pace. Some of this time is dedicated to conducting formative assessment with full solutions provided to assessment questions to inform student learning and self-monitor progress through the material. (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.
Should the public health situation require it, the present-in-person teaching activities will be replaced by synchronous online sessions. It can be replaced with a description of the lab using online materials including re-recorded data if PiP Sessions cannot go ahead.

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.
One of the examinations (1.5hr) focusses on the student experience in the laboratory and the other (2.0hr) examines the LO’s across the full range of the rest of the syllabus.
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.
