This study examined the relevance of improvised manual foot pump in instruction delivery of motor vehicle mechanics in technical colleges in Rivers State. Specifically, this study sought to examine the relevance of improvised manual foot pump in instruction delivery of two strokes automotive engine and lubrication system in technical colleges in Rivers State. This study adopted descriptive survey design. The population of this study comprised 29 motor vehicle mechanics teachers and 16 motor vehicle mechanics instructors in technical colleges in Rivers State. The population was manageable and was used for the study, therefore, there was no sampling method adopted. Two objectives were formulated, answered and tested at .05 level of significance. The instrument used for this study was a survey questionnaire. The instrument was face validated by two experts in the Department of Vocational and Technical Education in Ignatius Ajuru University of Education, Port-Harcourt and it was tested for reliability using Cronbach Alpha Reliability Coefficient method. A reliability value of .93 was obtained. Mean with Standard Deviation were used to answer the research questions while t-test statistical tools was used to test the hypotheses. This study found among others that the use of locally fabricated manual foot pump will facilitate the teaching of parts of piston, feature of cylinder, piston movement, top dead center and bottom dead center, strokes, among others. It could also facilitate the teaching of suction and discharge thereby captivating the interest of students to learn Motor vehicle mechanics which is seen as abstract subject. Therefore, it was recommended that manual foot pump should be fabricated by students so that it could be used for teaching two strokes automotive engines for effective instruction delivery.
