The emergence of ICT has changed the global status of education. Multimedia instruction which offers alternative to traditional paradigm of learning has made learning more meaningful, accessible and interactive within and outside the classroom. However, Nigeria has not fully embraced the use of multimedia instruction in teaching and learning. Therefore, the study aimed at investigating the effects of multimedia instruction on retention and achievement of basic machining skills in mechanical engineering craft practice. The study was conducted in four selected Technical colleges in Adamawa and Taraba states Nigeria. The population was 252 students in National Technical Certificate (NTC) 2. A sample of 156 were drawn from the population using Yaro Yamane’s formula. The design of the study was experimental. The sample drawn were divided into control and experimental groups. Experimental group were taught with multimedia instruction while control group were taught with demonstration method. Instructional video files, and lesson plan, teacher’s made test for pretest and posttest, were the instrument developed, validated by three experts and used for data collection. Two research questions and two hypotheses were raised. Mean and standard deviation were used to answer the research questions. t-test statistics was used to test the hypotheses at 0.05 level of significance. The research findings indicated that there is a significance difference between the mean performances of students in the experimental group than those students in the control group. The students in the experimental group performed better in mechanical craft practice and in retention test than those in the control group. Hence multimedia instructions have more effect on learning achievement and retention of skills in craft practice. The study recommended that multimedia instructional tool is an effective tool for enhancing teaching and learning of practical skills in mechanical craft.
