| DEVELOPMENT AND VALIDATION OF INSTRUMENT FOR ASSESSING PRACTICAL SKILSS IN FAULT DIAGNOSES AND REPAIRS OF RADIO AND TELEVISION SYSTEMS IN NIGERIAN TECHNICAL COLLEGES |
This study developed and validated a radio and television skill assessment scale (RTSAS) that will improve the assessment of students' performance in diagnoses and repairs of faults in radio and television systems. The study answered one research question and tested two hypotheses. The RTSAS comprising of practical skills based on National Business and Technical Examinations Board (NABTEB) curriculum and related literature were developed and validated by seven experts. Radio and television teachers from technical colleges in the South-South zone of Nigeria were the sample used for item validation of the RTSAS which was further tried out on radio and television students. Data collected were analyzed using statistical mean, Cronbach's Alpha and One Way Analysis of Variance (ANOVA). The result of the study showed that six clusters and 76 practical skills were found appropriate for the RTSAS. Also, the instrument was found to possess a high reliability of 0.95. Based on this result, it was recommended amongst others that radio and television teachers in technical colleges and other similar institutions in Nigeria should be made to be aware and learn to use the RTSAS for assessing performance in radio and television fault diagnoses and repairs. |

| Effective students’ involvement in public relations: a strategy for improving enrolment into technical teacher education programme in Nigeria |
The study was undertaken to determine the strategies for improving enrolment into technical teacher education programme in Nigeria through students' involvement in school public relations activities. Two reserach questions were formulated and one null hypothesis tested at 0.05 percent level of significance. Questionaire was the instrument used in data collection, while Mean and ttest statistics were used for data analysis. Results showed that the following strategies among others were identfied for improving enrolment in technical teacher education through students involvement in public relations: integrating public relations in school curriculum; proper funding of the scheme and engaging students regularly in exhibitions and job fairs. Consequently, it was recommended among other things that well coordinated and funded public relations units with well defined responsibilities of students be established in technical teacher institutions in Nigeria |

| Technical Skills Needed by Motor Vehicle Mechanic Apprentice to Establish Standard Motor Mechanic Enterprise in Port Harcourt Metropolis, Rivers State |
The study investigated mechanical technical skills required by apprentice of motor vehicle mechanic (MVM) to qualify for graduation as MVM artisan and establish standard motor mechanic enterprise in Port Harcourt metropolis. The study adopted the descriptive survey research design. The sample of the study comprised 63 MVM artisans operating in MVM workshops in Ikoku Mechanic village Diobu, Port Harcourt, who were purposively sampled. The instrument used for data collection was a structured questionnaire which was faced validated by three experts. The reliability of the instrument was established by using Cronbach Alpha reliability method to obtain the reliability coefficient was 0.86. Three research questions guided the study. Mean and standard deviation were used to answer the research questions. The study revealed modern technical skills in maintenance of ignition systems, carburetors as well as wheel alignment and balancing required by MVMW apprentice to qualify for graduation as MVM artisan and establish standard Motor Vehicle Mechanic enterprise in Port Harcourt metropolis. Based on the findings, recommendation were made among which included: Government should establish modern motor vehicle mechanic workshops that would train apprentice of MVM on technical skills required in maintaining and repairing of fuel system, ignition system and wheel alignment and balancing of motor vehicles wheels and tyres. The industries and motor vehicle companies should establish more service centres in Port Harcourt metropolis to train interested youths at subsidized rate. |
