CURRICULUM AND COURSE SPECIFICATIONS

PROFESSIONAL DIPLOMA IN ELECTRICAL/ELECTRONIC ENGINEERING GENERAL INFORMATION Philosophy and Objectives of Programme The overall philosophy of the professional diploma programme is to upgrade, as well as diversify the offerings of the polytechnics as tertiary institutions which should be capable of producing full professionals that can be registered to practice their various fields at the highest level and to provide further academic preparation for those who can benefit from post-graduate degree work. In this regard, the programme will raise the academic standard of the institution, remove stagnation in academic development and research activities and generally encourage growth and development in the polytechnic system to complement other tertiary institutions in the country. In more specific terms, the programme will enable the diplomates to meet the educational requirements of the relevant professional registration council, as well as the minimum requirements for admission into a post-graduate degree programme. Admission requirements (i)

The admission requirements for the professional programme is a minimum of an upper credit pass in the HND examination obtained from an institution whose programme has earned NBTE accreditation or any other equivalent qualification; and

(ii)

satisfactory completion of the NYSC

Duration Of The Programme The duration of the full-time course is 18 calendar months, that is, at least three semesters.

1

CURRICULUM The curriculum of the Professional Diploma Programme consists of two areas of concentration. (i)

Common courses

(ii)

Optional courses.

The common courses are listed in the curriculum table with code EEC. A student enrolled in the programme must take them irrespective of the option in which the student wishes to specialise. The optional courses are3 specialist courses aimed at further concentration in an area of specialisation. For Electrical/Electronic Engineering, the options are (1) Communication Electronics Engineering (2) Power and Machines (3) Instrumentation & Control. PROJECT Every student enrolled in the programme will be expected to undertake and submit a project work on an industrial/technical programme approved by the lecturer, to which he will proffer appropriate solutions. A dissertation shall be submitted on the project work, which will be orally examined. WHO QUALIFIES FOR THE AWARD OF THE PROFESSIONAL DIPLOMA Only candidates who met the minimum entry requirements as stated above or their equivalents, and who successfully completed all the prescribed courses, examination and projects/dissertation and the required credit hours of study as shown in the curriculum and course specification for the programme shall be eligible for the award of the professional diploma. Candidates who have not taken such general studies courses as “Use of English” and “Engineer in Society? At HND level, should arrange and take such courses before graduation.

ELIGIBILITY TO MOUNT THE PROFESSIONAL DIPLOMA PROGRAMMES To be eligible to mount the professional diploma programme: (a)

the institution should have been properly established

(b)

the corresponding Higher National Diploma must have earned NBTE programme accreditation in the discipline; and

(c)

the institution have adequate resources to support the programme.

ACCREDITATION The programme must have earned NBTE’s accreditation. Details of accreditation are contained in a separate publication available from the Executive Secretary, Programmes Department, NBTE, P.M.B. 2239, Kaduna. Grading of Students’ Work Students’ work and examinations during the course should have the letter grades and honors/quality point assigned to the marks obtained as shown in the table below: SCORES

(2)

(3)

Lower Credit CGPA of 2.50-3.49

(4)

Pass CGPA of 1.00-2.49

(5)

Fail CGPA of Below 1.00

EXTERNAL MODERATION/EXAMINING External examiners shall be required for both practical and written examination; and the oral examinations for the dissertation. Candidates must defend their project work orally in the presence of a panel consisting of the external examiners and staff of the institution.

4

The external examiners shall be two, one representing the professional registration council and the other one from the academic community (Polytechnic or University). In appointing external examiners from the registration council, the institution shall request the council to submit names of three nominees; if all three nominees are not acceptable to the institutions, the registration council shall be so informed of the reason for the rejection. In this regard a fresh list of nominees shall be sent to the institution. Note that the final decision on who shall be the external examiners is the responsibility of the institution’s Academic Board. External examiners shall not be lower in rank than Principal Lecturer in a Polytechnic or industry. All external examiners should be registered members of the professional registration council (if any) for the discipline or such persons of repute in academic or in the profession. DUTIES OF EXTERNAL EXAMINERS The appointment of external examiners is an important aspect of institutional self-regulation of its academic activities. It is the means by which an institution involves independent assessors to confirm that its academic standards are good and fair play prevails in the assessment of students’ performance. It also ensures that parity being achieved between the qualifications awarded to candidates of the same level with those of other similar institution and programmes. The duties of external examiners shall include: 1)

Moderation of examination question papers

2)

Moderation of answer scripts.

3)

Scrutinizing and assessing all projects of graduating students

4)

Ensuing that minimum standards of academic work required for the award of diplomas are similar for the level of students or diplomates. External Examiners shall be required to submit detailed report to the institution. Details to be included in the report are explained in the “Guideline for External Examiners” which is available from the NBTE.

GUIDANCE NOTES FOR TEACHERS The new curriculum is drawn in unit courses. This is in keeping with the provision of the National Policy on Education which stresses the need to introduce the semester credit units which will enable a student who so wish to transfer the credits already completed to an institution of similar standard from which he is transferring. As the success of the credit unit system depends on the articulation of programmes between the institutions and industry, the professional registration councils and other higher educations, the curriculum content has been written in behavioral objectives so that it is clear to all, the expected performance of the student who successfully completed the courses of the programme. There is a slight departure in the presentation of the performance based curriculum which requires the conditions under which the performances are expected to be carried out and the criteria for the acceptable levels of performance. It is deliberate attempt to further involve the staff of the department teaching the programme to write their own curriculum, stating the conditions existing in their institutions 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 aims are 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. 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.
