Quality Assurance of Instructors in Developing Workshop Based Test for Assessing Practical Skills of Students in Electronic Maintenance and Repair

Abstract

The study investigated the quality assurance of instructors in developing workshop based test for assessing practical skills of students in electronic maintenance and repair in the polytechnics in southwestern, Nigeria. Three research questions guided the study. Descriptive survey design was adopted for the study. The population for the study was 100 instructors from ten government established polytechnics in south western Nigeria. The study involved all the 100 subjects because of their manageable size. Workshop based test and seven item structured questionnaire were used for data collection. The instruments were validated by three experts while Split half technique, Cronbach alpha and product moment correlation coefficient were used to determine the reliability of the two sets of instruments with a coefficient of 0.84 for the questionnaire items and 0.83 for the workshop based test. One hundred copies of the instrument were administered on respondents by the researchers on one to one basis. All the one hundred copies of the instrument were retrieved and analyzed using frequency, percentage, mean and improvement needed index to answer the research questions. It was found out that the instructors of electronic maintenance and repair had no competency in developing workshop based test that will reflect all levels of Simpson psychomotor domain. The study also found out that the instructors needed improvement in developing workshop based test for assessing practical skills of students in electronic maintenance and repair.
