<![CDATA[This study aims to determine the effect of the Contextual Teaching and Learning (CTL) model and learning motivation on the K3LH (Occupational Health, Safety, and Environment) learning outcomes of Grade X TKP students at SMK Negeri 2 Medan. The research sample consisted of two classes—X TKP 2 (taught using the CTL model) and X TKP 1 (taught using the Direct Instruction/DI model)—with 34 students in each. A quasi-experimental method with a 2×2 factorial design was employed, comprising pre-test, instruction, and post-test stages. The research instruments underwent testing for validity, reliability, difficulty level, and discriminatory power. Homogeneity test results indicated that both groups originated from a homogeneous population (F-calculated = 1.671 < F-table = 7.815). A two-way ANOVA revealed significant differences in learning outcomes between students taught via the CTL and DI models (F-calculated = 10.55 > F-table = 3.99) and between students with high and low learning motivation (F-calculated = 24.77 > F-table = 3.99). However, no interaction effect was found between the learning model and learning motivation regarding learning outcomes (F-calculated = 3.60 < F-table = 3.99). Thus, the CTL learning model and learning motivation influence students' K3LH learning outcomes, offering a consideration for teachers and schools aiming to improve academic performance.]]>
