General information AIM: To give training and impart the necessary skills leading to the production of craftsmen, technicians and other skilled personnel who will be enterprising and self - reliant. ENTRY QUALIFICATIONS CRAFT PROGRAMME Candidates must not be less than 14 years of age and should have successfully completed three years of Junior Secondary education or its equivalent. Special consideration may be given to sponsored candidates with lower academic qualifications who hold trade test certificates and are capable of benefiting from the programme. ADVANCED CRAFT PROGRAMME Candidates should possess the National Technical Certificate or its equivalent and should have had a minimum of two years post qualification cognate industrial experience. THE CURRICULUM The Curriculum of each programme is broadly divided into three components: a. General Education, which accounts for 30% of the total hours required for the programme b. Trade Theory, Trade Practice and Related Studies which account for 65% and c. Supervised Industrial Training/Work Experience, which accounts for about 5% of the total hours required for the programme. This component of the course which may be taken in industry or in college production unit is compulsory for the full-time students Included in the curriculum is the teacher’s activity and learning resources required for the guidance of the teacher. Unit Course/Module A Course/Module is defined as a body of knowledge and skills capable of being utilized on its own or as a foundation or pre-requisite knowledge for more advanced work in the same or other fields of study. Each trade when successfully completed can be used for employment purposes.

BRHAVIOURAL OBJECTIVES These are educational objectives which identify precisely the type of behaviour a student should exhibit at the end of a course/module or programme. Two types of behavioural objectives have been used in the curriculum. They are: a. General Objectives b. Specific learning outcomes General Objectives are concise but general statements of the behaviour of the students on completion of a unit of work such as understanding the principles and application. a. Orthographic projection in engineering/technical drawing b. Loci in Mathematics c. Basic concepts of politics and government in Political Science d. Demand and Supply in Economics Specific Learning outcomes are concise statements of the specific behaviour expressed in units of discrete practical tasks and related knowledge the students should demonstrate as a result of the educational process to ascertain that the general objectives or course/programme have been achieved. They are more discrete and quantitative expressions of the scope of the tasks contained in a teaching unit. GENERAL EDUCATION IN TECHNICAL COLLEGES The General Education component of the curriculum aims at providing the trainee with complete secondary education in critical subjects like English Language, Economics, Physics, Chemistry, Biology, Entrepreneurial Studies and Mathematics to enhance the understanding of machines, tools and materials of their trades and their application and as a foundation for post-secondary technical education for the above average trainee. Hence, it is hoped that trainees who successfully complete their trade and general education may be able to compete with their secondary school counterparts for direct entry into the polytechnics or colleges of education (Technical) for ND or NCE courses respectively. The Social Studies component is designed to broaden the trainee’s social skills and his understanding his environment. For purpose of certification, only the first three courses in Mathematics will be required. The remaining modules are optional and are designed for the above average students. National Certificate The NTC and ANTC programmes are run by Technical Colleges accredited by NBTE NABTEB conducts the final National Examination and awards certificates. 3

Trainees who successfully complete all the courses/modules specified in the curriculum table and passed the national examinations in the trade will be awarded one of the following certificates S/NO LEVEL

Guidance Notes For Teachers Teaching The Curriculum The number of hours stated in the curriculum table may be increased or decreased to suit individual institutions’ timetable provided the entire course content is properly covered and the goals and objectives of each module are achieved at the end of the term The maximum duration of any module in the new scheme is 300 hours. This means that for a term of 15 weeks, the course should be offered for 20 hours a week. This can be scheduled in sessions of 4 hours in a day leaving the remaining hours for general education. However, (properly organised and if there are adequate resources), most of these courses can be offered in two sessions a day, one in the morning and the other one in the afternoon. In so doing, some of these programmes may be completed in lesser number of years than at present. The sessions of 4 hours include the trade theory and practice. It is left to the teacher to decide when the class should be held in the workshop or in a lecture room. INTEGRATE APPROACH IN THE TEACHING OF TRADE. Theory, Trade Science And Trade Calculation The traditional approach of teaching trade science and trade calculation as separate and distinct subjects in technical college programmes is not relevant to the new programme as it will amount to a duplication of the teaching of mathematics and physical science subjects in the course. The basic concepts and principles in mathematics and physical science are the same as in the trade calculation and trade science. In the new scheme therefore, mathematics and physical science will be taught by qualified persons in these fields and the instructors will apply the principles and concepts in solving trade science and calculation problems in the trade theory classes. To this end, efforts have to be made to ensure that mathematics and science modules required to be able to solve technical problems were taken as pre-requisite to the trade module. Evaluation Of Programme/Module For the programme to achieve its objectives, any course started at the beginning of a term must terminate at the end of the term. 4

Instructors should therefore device methods of accurately assessing the trainees to enable them give the student’s final grades at the end of the term. A national examination will be taken by all students who have successfully completed their modules. The final award will be based on the aggregate of the scores attained in course work and the national examination.

Guidelines for Text Book Writers NATIONAL/ADVANCED TECHNICAL CERTIFICATE IN REFRIGERATION AND AIR CONDITIONING WORK 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 mind 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. 1. One book should be produced for each syllabus 2. Page size should be A4 3. The front size should be 12 points for normal text and 14 point where emphasis is needed. 4. Line spacing should be set to 1.5 lines 5. Headings and subheadings should be emboldened 6. Photographs, diagrams and charts should used extensively throughout the book, and these items must be up-to-date 7. In all cases the material must be related to industry and commerce, using real life examples wherever possible so that the book is not just a theory book. It must help the students to see the subject in the context of the ´real word’ 8. 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 an artificial divide between theory and practice. 9. Examples should drawn from Nigeria wherever possible, so that the information is set in a country text. 10. Each chapter should end with student self-assessment questions (SAG) so that students can check their own master of the subject. 11. Accurate instructions should be given for any practical work having first conducted the practical to check that the instructions do indeed work. 12. The books must have a proper index or table of contents, a list of references and an introduction based on the overall course philosophy an aims of the syllabus. 13. Symbols and units must be listed and a unified approach used throughout the book. 14. In case of queries regarding the contents o the books and the depth of information, the author must contact the relevant curriculum committee via the National Board for Technical Education. 15. 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.
