DEVELOPMENT AND VALIDATION OF A PSYCHOMOTOR SKILLSASSESSMENT TOOL FOR ELECTRICAL INSTALLATION AND MAINTENANCEWORKS TRADE OF TECHNICAL COLLEGES IN NIGERIA

Abstract

This study was carried out to develop and validate EIMW trade psychomotor skill assessment
tool for technical colleges in Nigeria. Instrumentation research design was adopted for the
study. The population comprised of 160 EIMW trade teachers from the nineteen federal science
technical colleges in Nigeria. Four research questions were posed to guide the study.
Instrument for data collection was tagged EIMWTPSATQ with 198 items. The instrument was
subjected to face and content validity by three experts from department of electrical technology
education, Modibbo Adama University Yola. The reliability of the instrument was obtained via
Cronbach Alpha with a coefficient index of 0.99. Mean and standard deviation, factor analysis,
Cronbach Alpha, and intraclass correlation were used to answer each research respectively.
Findings of the study revealed that the content of the EIMWTPSAT measures accurately what
it is purported to measure. Furthermore, the EIMWTPSAT is consistent and demonstrated an
acceptable level of inter-rater agreement. The research therefore recommends for the adoption
of the developed and validated EIMWTPSAT for use in all technical colleges in Nigeria
because it will no doubt remove the inconsistences associated with performance assessment in
Workshops of Electrical Installation & Maintenance Works trade, and also help the students
improve on their practical performance.
