Abstract


The study aimed at development and validation of workshop-based process test instrument for assessing students’ skills in mechanical engineering craft trade in technical colleges. The purpose of the study was to develop an instrument for assessing students’ performance in lathe machining operations at technical college level. Two research questions were posed to guide the study. Instrumentation research design was adopted for the study and the instrument used for data collection was a structured questionnaire developed by the researcher. The 3 psychomotor objectives identified by the teachers were transformed to items for the draft Machining Process Skill Test Instrument (MAPTI). The draft MAPTI was face and content validated by three (3) experts. The data generated were analyzed using mean, standard deviation, Content Validity Index (CVI) 0.70, Cronbach’s Alpha (0.83), and Analysis of Variance (ANOVA) tested at 0.05 level of significance. The results of the data analyzed relating to psychomotor objectives for assessment revealed 21 operations items along 2 tasks were identified for the final draft of instrument (MAPTI). it was recommend that among others Teachers of mechanical engineering craft trade should use the instrument (MAPTI) in measuring the strength and weaknesses of their students in practical lessons and also during teacher made test, teachers should use the MAPTI using applicable operations as per level covered content area, and adjust grading to suit purpose.
