Abstract

This study aimed to analyze the effect of the Video-Assisted Problem Based Instruction (PBI) learning model on students’ learning outcomes in Lathe Machining Engineering by controlling learning motivation variables. The study employed a quasi-experimental method using a Post-test Only Control Group Design. The research sample consisted of 50 students divided into an experimental class (25 students) and a control class (25 students) at SMKS Semen Padang. Data collection instruments included learning outcome tests and learning motivation questionnaires. Data were analyzed using Analysis of Covariance (ANCOVA). The findings demonstrated that the implementation of the video-assisted Problem Based Instruction learning model exerted a statistically significant effect on students’ learning outcomes, as indicated by the ANCOVA results of F(1,47) = 63.145 with a significance value of p < 0.001. The effect size was categorized as large with Partial Eta Squared = 0.573. However, learning motivation as a covariate did not significantly affect learning outcomes with F(1,47) = 0.001 and p = 0.974. Simultaneously, the model used in this research was significant with F(2,47) = 32.851 and p < 0.001 and contributed 58.3% to the variance of learning outcomes (R² = 0.583). Therefore, video-assisted Problem Based Instruction was proven effective in improving students’ learning outcomes in Lathe Machining Engineering
