This book is written for one of the many technician courses now being run at technical colleges in accordance with the requirements of the Technician Education Council (TEC).
This Council was established in March 1973 as a result of the recommendation of the Government's Haslegrave Committee on Technical Courses and Examinations, which reported in 1969.
TEC's functions were to rationalize existing technician courses, including the City and Guilds of London Institute (C.G.L.I.) Technician courses and the Ordinary and Higher National Certificate courses (O.N.C. and H.N.C.), and provide a system of technical education which satisfied the requirements of 'industry' and 'students' but which could be operated economically and efficiently.
Four qualifications are awarded by TEC, namely the Certificate, Higher Certificate, Diploma, and Higher Diploma.
The Certificate award is comparable with the O.N.C. or with the third year of the C.G.L.I. Technician course, whereas the Higher Certificate is comparable with the H.N.C. or the C.G.L.I. Part III Certificate.
The Diploma is comparable with the O.N.D. in Engineering or Technology, the Higher Technician Diploma with the H.N.D. Students study on a part-time or block-release basis for the Certificate and Higher Certificate, whereas the Diploma courses are intended for full-time study.
Evening study is possible but not recommended by TEC. The Certificate course consists of fifteen Units and is intended to be studied over a period of three years by students, mainly straight from school, who have three or more C.S.E.
Grade III passes or equivalent in appropriate subjects such as mathematics, English, and science. The Higher Certificate course consists of a further ten Units, for two years of parttime study, the total time allocation being 900 hours of study for the Certificate, and 600 hours for the Higher Certificate.
The Diploma requires about 2000 hours of study over two years, the Higher Diploma a further 1500 hours of study for a further two years.
Each student is entered into a Programme of study on entry to the course; this program leads to the award of a Technician Certificate, the title of which reflects the area of engineering or science chosen by the student, such as the Telecommunications Certificate or the Mechanical Engineering Certificate.
TEC has created three main Sectors of responsibility Sector A responsible for General, Electrical and Mechanical Engineering Sector B responsible for Building, Mining and Construction Engineering Sector C responsible for the Sciences, Agriculture, Catering, Graphics, and textiles.
Each sector is divided into program committees, which are responsible for the specialist subjects or programs, such as AI for General Engineering,
A2 for Electronics and Telecommunications Engineering, A3 for Electrical Engineering, etc. Colleges have considerable control over the content of their intended programs since they can choose the Units for their programs to suit the requirements of local industry, college resources, or student needs.
These Units can be written entirely by the college, thereafter called a college-devised Unit, or can be supplied as a Standard Unit by one of the program committees of TEC.
Assessment of every Unit is carried out by the college and a pass in one Unit depends on the attainment gained by the student in his coursework, laboratory work, and an end-of-Unit test.
TEC moderate college assessment plans and their validation; external assessment by TEC will be introduced at a later stage. The three-year Certificate course consists of fifteen Units at three Levels: I, II, and III, with five Units normally studied per year.
Entry to each Level I or Level II Unit will carry a prerequisite qualification such as C.S.E. Grade III for Level I or 0-level for Level II; certain Craft qualifications will allow students to enter Level II direct, one or two Level I units being studied as 'trailing' Units in the first year.
The study of five Units in one college year results in the allocation of about two hours per week per unit, and since more subjects are often to be studied than for the comparable City and Guilds course, the treatment of many subjects is more general, with greater emphasis on an understanding of subject topics rather than their application.
Every syllabus to every Unit is far more detailed than the comparable O.N.C. or C.G.L.I. syllabus, presentation in Learning Objective form being requested by TEC.
For this reason, a syllabus, such as that followed by this book, might, at first sight, seem very long, but analysis of the syllabus will show that 'in-depth' treatment is not necessary--objectives such as ' ... states Ohm's law ... ' or ' ... lists the different types of telephone receivers
.. .' clearly do not require an understanding of the derivation of the Ohm's law equation or the operation of several telephone receivers.
This book satisfies the learning objectives for one of the many TEC Standard Units, as adopted by many technical colleges for inclusion into their Technician programs.
The treatment of each topic is carried to the depth suggested by TEC and in a similar way the length of the Unit (sixty hours of study for a full Unit), prerequisite qualifications, credits for alternative qualifications, and aims of the Unit have been taken into account by the author.
