ABSTRACT:

The dwindling psychomotor skills and interest in the study of electrical installation and maintenance work among students in technical colleges necessitated this study. The study is aim at determining the relative effectiveness of demonstration and project-based teaching methods in developing students’ psychomotor skill and interest in electrical installation and maintenance work in technical colleges in Anambra State. Six research questions and eight null hypotheses guided the study. The quasi-experimental research design was adopted for the study. Population comprised 343 National Technical Certificate 11 (NTC) students offering electrical installation and maintenance work in the twelve technical colleges in Anambra State. Purposive sampling technique was used to select a sample size of 80 students from two colleges based on schools that have good number of male and female students. Psychomotor Skill Performance Test in Electrical Installation and Maintenance Work (PSPTEIMW) and Electrical Installation and Maintenance Work Interest Inventory Scale (EIMWIIS) were used to collect data for the study. The PSPTEIMW has been validated by test developers in the National Business and Technical Examination Board while EIMWIIS was face validated by experts in the field of technical education. A pilot study was used to establish the reliability of the instruments by administering them to 30 NTC II students of government technical college Okporo, Orlu in Imo state who were not part of the population of the study. Internal consistency of the instruments was determined using Cronbach Alpha technique and reliability coefficient values of 0.82 and 0.80 respectively were obtained. Data collected from the study were analyzed using arithmetic mean to answer the research questions while the hypotheses were tested using Analysis of Covariance (ANCOVA) at 0.05 level of significance. The findings revealed that the two methods improved students’ psychomotor skill development and interest in electrical installation and maintenance work but project-based teaching method was slightly more effective. There was significant difference in the psychomotor skill development and interest scores of students based on the teaching methods but there was no significant interaction effect of teaching methods and gender in the students’ psychomotor skill development and interest in electrical installation and maintenance work. It was, therefore, recommended among others that technical teachers should adopt demonstration and project-based teaching methods consistently to develop students’ psychomotor skills in relevant trades in technical colleges in Nigeria.
