These are: i. General studies/education ii. Foundation courses iii. Professional courses iv. Supervised Industrial Work Experience Scheme (SIWES) 5.2 The General Education component shall include courses in: i. Art and Humanities - English Language, Communication, History. ii. Social Studies - Citizenship Education, Political Science Sociology, Philosophy, Geography, Entrepreneurship, Philosophy and Sociology are compulsory. iii. Physical and Health Education - One semester credit only. 5.3 The General Education component shall account for not more than 15% of the total contact hours for the programme. 5.4 Foundation courses include courses in Economics, Mathematics, Pure Sciences, Technical Drawing, Descriptive Geometry, Statistics, etc. The number of hours for the Programme may account for about 1015% of the total contact hours. 5.5. Professional courses are ore courses of the programme which give the student the theory and professional skills he needs to practise his field of calling at the technician/technologist level. These may account for between 60-70% of the contact hours. 5.6. Student Industrial Work Experience Scheme (SIWES) shall be taken during the long vacation following the end of the second semester of the first year. See details of SIWES at section 11.0 5.7. Personal Logbook: The students to maintain a personal Logbook to record all the daily and weekly summary of all the practical activities for all the semesters. 6 6.0 CURRICULUM STRUCTURE The structure of the National Diploma programme consists of four semester of classroom, laboratory and workshop activities in the college, and a semester (3-4 months) of student Industrial Work Experience Scheme (SIWES). Each semester shall be of 18 weeks duration made up as follows: a. 15 contact weeks of teaching, i.e. recitation, practical exercise, quizzes, test, etc, and b. 3 weeks for examinations and registration. SIWES shall take place at the end of the second semester of the first year. 7.0 ACCREDITATION The Diploma programme shall be accreditation by the National Board for Technical Education before the diplomates can be awarded the National Diploma certificates. Details about the process of accrediting a programme for the award of the National Diploma are available from the Executive Secretary, National Board for Technical Education, Plot “B”, Bida Road, P.M.B. 2239, Kaduna, Nigeria. 8.0 AWARD OF NATIONAL DIPLOMA Conditions for the award of National Diploma include the following: a. Satisfactory performance in all prescribed course work which may include class work, tests, quizzes. Workshop practice, laboratory work which should amount to a minimum of between 72 and 80 semester credit units. b. Supervised industrial work experience for four months. c. Satisfactory performance at all semester examinations. d. Satisfactory completion of final year project work Normally, continuous assessment contributes 30% while semester examinations are weighted 70% to make a total of 100%. The industrial training is rated on the basis of pass or fail. National Diploma should be awarded in four classes: (i) Distinction - CGPA of 3.50 and above (ii) Upper Credit - CGPA of 3.0 - 3.49 (iii) Lower Credit - CGPA of 2.50 - 2.99 (iv) Pass - CGPA of 2.00 - 2.49. 7 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 - 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 acceptance level of performance. Departmental submission on the final curriculum may be vetted by the Academic Board of the institution. 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. 8 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 industrybased supervisor. 11.2 Evaluation of students during SIWES. In the evaluation of the student, cognisance should be taken of the following items: 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 which has been agreed to by all polytechnics is adopted. 11.4 The Institution-Based Supervisor: The institution-based supervisor should initial the log-book 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. 9 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 carryout 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. 10 Curriculum Tables First Semester COURSE CODE COURSE/ MODULE TITLE L T P CU CH GNS 101 Use of English I (Grammar) 2 - - 2 2 GNS 111 Citizenship Education 2 - - 2 2 MTH 112 Algebra and Elementary Trigonometry 2 1 - 3 3 MEC 111 Mechanical Engineering Science (Statics) 2 - 2 4 4 MEC 112 Technical Drawing 1 - 4 5 5 MEC 113 Basic Workshop Technology and practice 1 - 4 5 5 EEC 115 Electrical Engineering Science I 2 - 2 4 4 ICT 101 Introduction to Computing - - 3 3 3 Total 12 1 15 28 28 Second Semester COURSE CODE COURSE/MODULE TITLE L T P CU CH GNS 201 Use of English II (Essay and Comprehension) 2 - - 2 2 SDV 210 Entrepreneurship Development I 2 - - 2 2 MEC 221 Engineering Graphics 1 - 4 5 5 MEC 122 Thermodynamics I 2 - 2 4 4 MEC 123 Machine Tools Technology and Practice 2 - 4 6 6 MEC 124 Mechanical Eng.

They are intended to supplement the detailed syllabuses which have been produced, and which define the content and level of the courses. Authors should bear in minds that the curriculum has been designed to give the students a broad understanding of applications in industry and commerce, and this is reflected in the curriculum objectives. • One book should be produced for each syllabus • Page size should be A4 • The front size should be 12 point for normal text and 14 point where emphasis is need • Line spacing should be set to 1.5 lines • Headings and subheadings should be emboldened • Photographs, diagrams and charts should used extensively thought the book, and these items must be up-to-date • In all cases the material must be related to industry and commerce, using real life examples wherever possible so that the book is just a theory book. It must help the students to see the subject in the content of the 'real word" • The philosophy of the courses is one of an integrated approach to theory and practice, and as such the books should reflect this by not making and artificial divided between theory and practice. • Illustrations should labeled and numbered. • Examples should drawn from Nigeria wherever possible, so that the information is set in a country context. • Each chapter should end with student self-assessment quotations (SAG) so that student can check their own master of the subject. 251 • Accurate instructions should be given for any practical work having first conducted the practical to check that the instructions do indeed work • The books must have a proper index or table of contents, a list of references and an introduction based on the overall course philosophy and aims of the syllabus. • Symbols and units must be listed and a unified approach used throughout the book • In case of queries regarding the contents of the books and the depth of information, the author must contact the relevant curriculum committee via the National Board for technical Education. • The final draft version of the books should be submitted to Nigerian members of the curriculum working groups for their comments regarding the content in relation to the desired syllabus. 252 List of Participants UNESCO-NIGERIA PROJECT IN SUPPORT OF REVITILISATION OF TECHNICAL AND VOCATIONAL EDUCATION IN NIGERIA PROJECT TEAM MEMBERS S/No. NAME DESIGNATION 1 Engr.
