Abstract: Nowadays, the use of video tutorial as a method of teaching and learning has become popular among educators. Video tutorial is more practical and can deliver more information to the users. Nonetheless, the mode of presentation can be hard to process in a short period. User-paced (or self-pacing) application in the multimedia presentation has been shown a positive effect on elaboration learning. Looking at this advantage, a user-paced video tutorial for machining operation is being introduced in the study. To identify the effectiveness of user-paced in video tutorial design, it was compared with the system-paced video tutorial (system determined the duration and pace of the information presented). The objectives of the study are; (i) to evaluate the effect of user-paced and system-paced of machine’s video tutorial on learning performance (overall); and (ii) to evaluate the effect of user-paced and system-paced of machine’s video tutorial on learning performance (by part of the video tutorial – safety, equipment, machine setup, procedure, and housekeeping). Sixteen participants completed the study where they were pseudo-randomly assigned into two different groups – User-paced or System-paced (eight participants for each group). The User-paced group was stimulated with four video tutorials where they have full control in pacing the tutorials, while the system-paced group was stimulated with four conventional video tutorials where they have no control in pacing the tutorials. After the video tutorials session, all participants were evaluated with quizzes that covered the content of the tutorials (one tutorial at a time), and the maximum score for the quizzes is 50 marks. The findings show that: (i) in overall, User-paced group performed better in the quizzes (88.66% percentage score) rather than the System-paced group (56.60% percentage score), and there is a significant difference in the learning performance for User-paced group (M=44.875, SD=1.959) and System-paced group (M=28.750, SD=3.105) conditions; t (14) = 12.421, p <0.001; and (ii) by category, User-paced group performed better in the quizzes rather than the System-paced group in all categories, and all the differences are significant. These findings show that the use of User-paced in designing video tutorial for machining operations would aid in improving users’ learning performances.
