The university "strategy for learning" documentation has informed the learning and teaching strategy for this module. The module material will be introduced through lectures, while practical exercises, based on the lecture material, will be given to students for their practical sessions. Tutorials will be used to help explain and elaborate on both the lecture material and the practical exercises and provide opportunities for tutor led formative feedback to students. This is detailed as follows
Policy of staff access for students, programme and library induction pack and supporting tour, module handbook providing detailed information.
Support of a module leader and programme leader, in addition to student representatives - these reflect students' views and concerns at staff-student liaison committee meetings and programme committee meetings.
Underpinning support is provided from central university support services including: online study skills facility, student counselling service, LDC, IT support using e-mail and/or on-line resources).
Knowledge and skills: the module develops knowledge and skills, and uses tools, techniques and methods which are immediately useful to employers, both in the UK and overseas.
Strong emphasis in the module on industrial or research projects with direct industrial input into the module, including the use of visiting lecturers and industrial visits.
The module is designed with very strong professional emphasis, informed directly by industrial expertise of staff and industrial liaison committees and professional body requirements as appropriate to enhance the career opportunities of the students in industry and academia.
The lecture delivery will be enhanced by a variety of forms including, where appropriate, videos, computer based models and other multimedia forms.
On line learning materials to be available electronically, discussion boards will be used to encourage teacher and peer-to-peer dialogue on certain topic areas where this form o
