Development of Drainage-System Maintenance Contents for Integration to Building Technology Programme of Nigerian Polytechnics

摘要

The study was carried out to develop drainage-system maintenance contents for integration to building technology programme of Nigerian polytechnics. The study was carried out in South- eastern Nigeria. Three research questions guided the study and three null hypotheses formulated were tested at 0.05 level of significance. The study adopted descriptive research design. The area of the study was Enugu State of Nigeria. The population for the study was 203 lecturers of technical education in tertiary institutions and supervisors in relevant industries. There was no sample because of the manageable sizes of the population of subjects. A structured questionnaire titled: Drainage ma Maintenance Questionnaire was used as the instrument for data collection. The instrument was validated by three experts and Cronbach alpha reliability method was adopted to determine the internal consistency of the questionnaire items while 0.82 was obtained. Out of two hundred and three copies of the questionnaire administered on respondents by the researchers, only 195 copies were duly retrieved which represents 95.06 percent return rate. The data collected were analyzed using mean while t-test was used to test the null hypotheses. The findings revealed that 49 drainage maintenance contents, for integration to building technology programme of Nigerian polytechnics, 48 facilities for implementing the drainage maintenance contents in Nigerian polytechnics while 25 evaluation techniques for assessing the performance of students of building technology programmes in Nigerian polytechnics were also determined. Recommendations include that the developed drainage maintenance contents should be integrated to building technology programme of Nigerian polytechnics. The recommendations also include that all the training facilities and resources identified should be provided by government and individuals with enabling abilities.
