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.

Guidelines for text book writers
NATIONAL DIPLOMA AND HIGHER NATIONAL DIPLOMA
The following guidelines are suggestions from the Engineering Committees to the writers of the textbooks for
the new curricula. 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.
