8.1 The new curriculum is drawn in unit courses This is in keeping with the provisions of the National Policy on Education which stress the need to introduce the semester credit units which will enable a student who so wish to transfer the units already completed in an institution of similar standard from which he is transferring 8.2 In designing the units, the principle of the modular system by product has been adopted; thus making each of the professional modules, when completed provide the student with technician operative skills, which can be used for employment purposes 8.2.1 As the success of the credit unit system depends on the articulation of programmes between the institutions and industry, the curriculum content has been written in behavioural objectives, so that it is clear to all, the expected performance of the student who successfully completed some of the courses or the diplomats of the programme There is a slight departure in the presentation of the performance based curriculum which requires the conditions under which the performance are expected to be carried out and the criteria for the acceptable 10 5.2 5.3 5.4 5.5 (b) Pulse-jet (c) Turbo-jet
