Abstract
This study was designed to assess the comparative effectiveness of project and demonstration teaching methods in improving students’ retention ability in basic electricity in technical colleges. The study adopted quasi-experimental design; specifically, the pre-test, post-test and delayed posttest for non-equivalent groups were used. One research question and one hypothesis tested at 0.05 level of significance guided the study. There are 4 technical colleges in Ebonyi State and each technical college offers basic electricity. A total of 141 Technical College II (TC II) students formed the population of the study. The instruments used in the study were Basic Electricity Achievement Test (BEAT), Project Method Instructional Manual (PMIM) and Demonstration Method Instructional Manual (DMIM), which were validated by three experts. Two experts were from Technology Education and the other expert from Measurement and Evaluation, Nnamdi Azikiwe Universty, Awka. Data collected was analyzed using mean and standard deviation, while the hypothesis was tested using Analysis of Covariance (ANCOVA). The study found that students taught basic electricity with project teaching method performed significantly higher in the mean retention ability than their counterparts taught with demonstration teaching method. This shows further that project teaching method was more effective than demonstration teaching method in improving students’ retention ability in basic electricity. The researchers recommends that since project teaching method has been found to be more effective in improving students’ retention ability in basic electricity, teachers should be encouraged, trained and motivated to apply project method in teaching basic electricity so as to improve their retention ability.
