Foreword

The National Diploma (ND) in Mechanical Engineering Technology curriculum is designed to be used by training institutions to produce manpower for academia and industries nationwide.

The acute shortage of professionally trained manpower in these industries in Nigeria as well as the need to produce professional practitioners with good ethics and career prospects, through the acquisition of desirable knowledge and skills, necessitated the production of this national curriculum.

It is my belief that this curriculum and course specifications which is the minimum required to produce technicians with sound knowledge and skills in Mechanical Engineering Technology, if properly implemented with the required resources (qualified teaching staff in adequate number and mix, adequate equipment/consumables, physical training facilities and teaching aids). Also, with qualified candidates admitted into the programme, will lead to the production of competent and skilled technicians required in the sector.

I wish to express my deep appreciation to those that made the development of this curriculum possible. The invaluable contributions of all the members of the committee and resource persons during the idea generation, pre-critique and national critique workshops are appreciated.

I hope that the curriculum would be properly implemented, so as to produce the required Work Force of our dream.

9.0 GUIDANCE NOTES FOR TEACHERS

9.1 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 similar standard from which he/she is transferring.

9.2 In designing the units, the principle of the modular system by product has been adopted, thus making each of the professional modules, when completed provides the student with technician operative skills, which can be used for employment purposes, self- reliance and otherwise.

9.3 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 diplomates of the programme. This is 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 levels of performance. It is a deliberate attempt to further involve the staff of the department teaching he programme to write their own curriculum stating the conditions existing in their institution under which performance can take place and to follow that with the criteria for determining an acceptable level of performance. The Academic Board of the institution may vet departmental submission on the final curriculum. Our aim is to continue to see to it that a solid internal evaluation system exists in each institution for ensuring minimum standard and quality of education in the programmes offered throughout the Polytechnic system.

9.4 The teaching of the theory and practical work should, as much as possible, be integrated. Practical exercises, especially those in professional courses and laboratory work should not be taught in isolation from the theory. For each course, there should be a balance of theory to practical in the ratio of 50:50 or 60:40 or the reverse.

10.0 LOGBOOK

A personal Log-book to be kept by the students shall contain all the day-to-day, weekly summary, and semester summary of all the practical activities from day one to the end of the programme. This is to be checked and endorsed by the lecturers concerned at the end of every week.

11.0 GUIDELINES ON SIWES PROGRAMMES

For the smooth operation of the SIWES, the following guidelines shall apply:

11.1 Responsibility for placement of students. a. Institutions offering the National Diploma programme shall arrange to place the students in industry. By April 30 of each year, six copies of the master-list showing where each student has been placed shall be submitted to the Executive Secretary,

National Board Technical Education, which shall, in turn, authenticate the list and forward it to the Industrial Training Fund, Jos; b. The placement officer should discuss and agree with industry on the following:

(a) A task inventory of what the students should be expected to experience during the period of attachment. It may be wise to adopt the one already approved for each field.

(b) The industry-based supervisor of the students during the period. It should be noted that the final grading of the students during the period of attachment should be weighted more on the evaluation by his industry-based supervisor.

11.2 Evaluation of students during SIWES.

In the evaluation of the student, cognizance should be taken of the following:

1. Punctuality 2. Attendance 3. General Attitude to work 4. Respect for Authority 5. Interest in the field/technical area 6. Technical competence as a potential technician in his field.

11.3 Grading of SIWES: To ensure uniformity of grading scales, the institution should ensure that the uniform grading of students‟ work that has been agreed to by all polytechnics is adopted.

11.4 The Institution-Based Supervisor: The institution-based supervisor should initial the logbook during each visit. This will enable him to check are being met and to assist students having any problems regarding the specific assignments given to them by their industry-based supervisor.

11.5 Frequency of Visit: Institution should ensure that students placed on attachment are visited within one month of their placement. Other visits shall be arranged so that:

1) there is another visit weeks after the first visit; and 2) a final visit in the last month of the attachment.

11.6 Stipend for Students in SIWES: The rate of stipend payable shall be determined from time-to-time by the Federal Government after due consultation with the Federal Ministry of Education, the Industrial Training Fund and the National Board for Technical Education.

11.7. SIWES as a component of the curriculum: The completion of SIWES is important in the final determination of whether the student is successful in the programme or not. Failure in the SIWES is an indication that the student has not shown sufficient interest in the field or has no potential to become a skilled technician in his field. The SIWES should be graded on a fail or pass basis. Where a student has satisfied all other requirements but failed SIWES, he may only be allowed to repeat another four months‟ SIWES at his own expense.

12.0 FINAL YEAR PROJECT

Final year students in this programme are expected to carry out a project work. This could be on individual basis or group work. The project should, as much as possible incorporates basic element of design, drawing and complete fabrication of a marketable item or something that can be put to use. Project reports should be well presented and should be properly supervised. The departments should make their own arrangement of schedules for project work.
