(iv) Supervised Industrial Works Experience Scheme (SIWES).

4.2 The General Education component shall include courses in:

Art and Humanities – English Language, Communication, History These are compulsory Mathematics and Science (for science based programmes).

non-Social Studies – Citizenship (the Nigerian Constitution) Political Science and Sociology are compulsory.

Physical and Health Education (one semester credit only).

4.3 The General Education component shall account for not more than 15% of total contact hours for the programme.

4.4 Foundation Courses include courses in Economics, Mathematics, Pure Sciences, Technical Drawing, Descriptive Geometry,

Statistics, etc The number of hours will vary with the programme and may account for about 10-15% of the total contact hours.

4.5 Professional courses are courses which give the student the theory and practical 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 depending on programme.

4.6 Supervised 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 paragraph 9.0

5.0 CURRICULUM STRUCTURE

5.1 ND Programme

The structure of the ND programme consists of four semesters of classroom, laboratory and workshop activities in the college and a semester (3-4 months) of Supervised Industrial Work Experience Scheme (SIWES) Each semester shall be of 17 weeks duration made up as follows:

- 15 contact weeks of teaching, i.e lecture recitation and practical exercises, etc

and 2 weeks for tests, quizzes, examinations and registration.

SIWES shall take place at the end of the second semester of the first year.

7.0 CONDITIONS FOR THE AWARD OF THE ND/HND

Institutions offering accredited programmes will award the National Diploma to candidates who successfully complete the programme after passing prescribed course-work, examinations, diploma project and the Supervised Industrial Work

Experience Such candidates should have completed a minimum of between 72 and 80 semester credit units depending on the programme Diplomas shall be awarded based on the following classification:

Distinction - GPA 3.50 – 4.0

Upper Credit - GPA 3.00 – 3.49

Lower Credit - GPA 2.50 – 2.99

8.0 GUIDANCE NOTES FOR TEACHERS TEACHING THE PROGRAMME

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

levels of performance It is a deliberate attempt to further involve the staff of the department teaching the programme to write their own curriculum stating the conditions existing in their institution under which the performance can take place and to follow that with the criteria for determining an acceptable 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.

8.4 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 be taught in isolation from the theory For each course, there should be a balance of theory to practice in the ratio of 50:50 or 60:40 or the reverse.

9.0 GUIDELINES ON SIWES PROGRAMME

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

9.1 Responsibility for Placement of Students

(a) Institutions offering the ND 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, NBTE which shall, in turn, authenticate the list and forward it to the Industrial Training Fund, Jos.

(c) The Placement Officer should discuss and agree with industry on the following:

(i) 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.

(ii) the industry based supervisor of the students during the period, likewise the institution based supervisor.

(iii) the evaluation of the student during the period, it should be noted that the final grading of the student during the

period of attachment should be weighted more on the evaluation by his industry based supervisor.

9.2 Evaluation of Students During the SIWES

In the evaluation of the student, cognisance should be taken of the following items:

(a) Punctuality

(b) Attendance

(c) General Attitude to Work

(d) Respect for Authority

(e) Interest in the field/technical area

(f) Technical competence as a potential technician in his field.

9.3 Grading of SIWES

To ensure uniformity of grading scales, the institution shall ensure that the uniform grading of students’ work which has been agreed to by all polytechnics is adopted.

9.4 The Institution Based Supervisor

The institution based supervisor should initial the log book during each visit This will enable him to check and determine to what extent the objectives of the scheme are being met and to assist students having any problems regarding the specific assignments given to them by their industry based supervisor.

9.5 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 six weeks after the first visit; and

(2) a final visit in the last month of he attachment.

9.6 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 NBTE.

9.7 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.
