Teaching / Learning Strategy

Balance of theory and practical illustration in lectures and practical lab sessions, with problem solving in small group teaching activities are the main teaching methods will be based on lectures with laboratory exercises used to relate theoretical concepts to practical experience. The students will be expected to perform directed reading exercises and self-learning exercises on emerging technologies. Tutorials will be used to reinforce the module material and to discuss the issues raised by the directed reading.
