Teaching And Learning Methods

Lectures, training in using computer software and supervised completion of a design project and technical writing.

Assessment and Grading Methods

Design project (50% of the final mark). The completion of the project incorporates elements of problem based learning. The supervision/assessment of the groups is achieved through weekly meetings with the teaching staff.
 
Written examination (50% of the final mark)
