Effects of Multimedia Instruction on Retention and Achievement of Basic Machining Skills in Mechanical Craft Practice

Abstract

The emergence of ICT has change 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 sample population was drawn from students in National Technical Certificate (NTC) 1 and NTC 2. One hundred and fifty students were randomly selected, 80 students from NTC 1 and 75 students from NTC 2. 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
