Skills on Occupational Standards in the Field of Electrical Installation of Higher Vocation Certificate

Abstract

The purpose of this research was to analyze skills on occupational standards in the field of electricalinstallation of Higher Vocation Certificate Curriculum B.E. 2546. The procedure was three steps. 1) Theresearchers analyzed their competences by functional map. 2) They were perceived by 20 experts. 3) Theskills on occupational standards as perceived by 223 teachers in electrical power department and 96practitioners in electricity area who work mainly on designing, installing and servicing electrical system inindustries.

The analysis on skills of occupational standards in this field by researchers were three dimension:Electrical system design, Electrical system installation and Electrical system service The constructed interviewform and record were used to interview the experts. These three dimensions was 18 units ofcompetences included 139 skills. The index of concurrence (IOC) was between 0.750 - 1.00. Theconstructed interview form was developed into a questionnaire and was tried out. The reliability of thequestionnaire were 0.73 to 0.90. Principal component analysis was used to analyze the factor. Orthogonalrotating with varimax method was used by computer program.

It was found that three dimensions on Occupational Standards in the field of Electrical Installationwere 1) Electrical system design included 6 factors according to 56 important variables. 2) Electricalsystem installation included 4 factors with 38 important variables. 3) Electrical system service included 2factors with 33 important variables. These factors could explain 71.72 percents of covariance.
