MANAGERIAL SKILLS REQUIRED OF TECHNICAL TEACHERS FOR EFFECTIVE TEACHING OF TECHNICAL DRAWING (EDUCATION PROJECT TOPICS AND MATERIALS)
Background of the Study
Technical drawing deals with graphical representations of ideas. According to Gagne, and Briggs. (2009), technical drawing is a means of clearly and concisely communicating all of the information necessary to transform an idea or concept into a reality. Technical drawing often contains more than just a graphical representation of its subject. It also contains dimensions, notes and specifications. The Federal Government of Nigeria (FGN) in National Policy on Education (2004), made technical drawing as an elective subject offered at secondary school level but National Board for Technical Education (NBTE)  stipulated that in technical colleges, technical drawing should be taught as a trade related course and should be taken by all students in engineering trade and construction trades except craft practice, this is due to the basic knowledge and skills it provides in engineering and construction courses. Therefore, technical drawing as a trade related course in technical college must be studied by all students in the technical related areas for an improved academic achievement. One of the objectives of technical drawing as contained in the handbook published by National Institute for Educational Development (NIED), (1997) is to solve practical and technological problems through the process of communication skills which are central to design and planning. It therefore becomes imperative that only competent teacher can teach technical drawing effectively. Competence is the ability to do something well. In the view of Hornby (2010), to be competent means that a person has the ability or power, to demonstrate knowledge, skills and attitudes that are sufficiently required to perform a given job or task. Nussel, Inglis and Wiersma (2006), explained that competency is a functional ability to apply to practical situation the essential principles and techniques of a particular subject matter or field. In this study, functional ability of teachers of technical drawing to demonstrate knowledge, skills and attitudes required in teaching technical drawing indicates competence. If on the other hand, one could not satisfactorily demonstrate knowledge, skills and attitudes required in the teaching, then the individual has a gap which shows lack of competence.
