(a) Teaching will be conducted using lectures, tutorials and practicals. (b) The Institute’s VLE will be used to evaluate the students understanding of the basic concepts during each section using online quizzes. (c) At the end of each section, self-test tutorial question sheets will be issued to the students. They will have one week to complete these questions. Any difficulties arising from the self-test question sheets will be addressed in class or laboratory sessions. (d) At various stages of the module students will be directed to online materials and resources and will also have to conduct independent research on specific topics for purpose of completing practical exercises and assignments. (e) The practical laboratory sessions will offer the students hands on laboratory experience using real measurement and test equipment, experimental apparatus and computational software environments. These applied experiments will serve to reinforce the theoretical knowledge and understanding of real world systems.
