### Teaching / Learning Strategy

Synthesis of class room lectures without and with OHP/Transparency sheets, power point projections, guest lectures, seminars and tutorials. Tutorials will be used to reinforce the module material discussed during lecture sessions. It also serves as a platform of technical discussions to clarify any queries that arise from directed studies.
