Subject-specific Skills:
- Will have acquired intellectual and practical skills in order to apply geological principles and methodologies to the solution of familiar and unfamiliar problems.
Key Skills:
- Prepare, process, interpret and present data using appropriate qualitative and quantitative techniques and packages.
- Solve numerical problems using computer or non-computer techniques.
Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module
- The module is delivered through a mix of one-hour lectures and two-hour practical slots, supported by handouts, directed reading and web and computer-based assignments.
- The practicals form an important component of the module allowing "hands on" learning and experience.
- Summative assessment is made up of practical tests.
- An unseen written exam will provide a test of the students understanding of supporting theory.
- Formative assessment is provided by web-based tests.
- Guidance on preparation, key and exam skills are provided.
