Teaching Rationale And Relationship

Specialist knowledge and understanding are primarily imparted via online lecture classes, supported by small group teaching sessions and computer-hosted reference materials. Subject specific skills are taught through a computer-based workshop (practical).
Students are encouraged and expected to learn through reflection and independent reading. They are supported in this by the provision of an extensive, but prioritised, reading list. Observations and discussions during the modelling workshop and small group teaching sessions sessions aid development of understanding. Subject specific skills are learnt through participation in, and reflection on, the small group teaching (tutorial) exercises and computer-based workshop and through completion of geochemical calculations (summative coursework assessment).
Key skills are practised through participation in the computer-based workshop.

Assessment Methods

Assessment Rationale And Relationship

The specialist knowledge and understanding imparted during this module are assessed by means the successful completion of the final computer based guided practical and its report in a piece of coursework and a single coursework item (a thermodynamic calculation exercise which employs a range of approaches in order to accurately assess student abilities with short essay, calculation and data interpretation components

An alternative assessment will be set for any Semester 1 Study Abroad student taking this module, who will not be in Newcastle during the January assessment period.
