Teaching Rationale And Relationship
Specialist knowledge and understanding are primarily imparted via 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.
The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship
The specialist knowledge and understanding imparted during this module are assessed by means of unseen written examination and a single coursework item (a thermodynamic calculation exercise). The examination paper employs a range of approaches in order to accurately assess student abilities. These may include essay, calculation, data interpretation, and multi-part questions.
