Development and Validation of Workshop-Based Process Skill Test in Metal Fitting for Improving Students’ Skills in Technical Colleges for Work

Abstract

The study focused on the development and validation of workshop-based process skill tests for assessing students in metal fitting trade in technical colleges. The study adopted the instrumentation design and was carried out in Nasarawa state. The population for the study was 25 NTC III students comprising 3 ability groups (8 high, 12 average and 5 low abilities).  A 92 draft copy of workshop-based process skill items were validated and utilized to developed the WBPST. The test was used in assessing students in government technical college Mada Station.  The data generated were analyzed using Cronbach Alpha, Kendell coefficient of concordance and Scheffe Test. The reliability of the test revealed coefficient of 0.76. It was found out that there were differences in the mean scores of the 3 ability groups (high, average and low). The inter-rater reliability coefficient of the WBPST was 0.57. It was therefore recommended that examination bodies (NABTEB and WAEC) should integrate the workshop-based process skill test items in their examination process for certification of NTC students.
