Abstract

Vocational education programs in Indonesia face persistent structural misalignment between graduate competencies and industry demands, reflected in the vocational high school graduate unemployment rate of 9.84% despite enrollment of 5.08 million students. This study examined the effects of Teacher Competency (X1), Learning Facilities (X2), and Student Motivation (X3) on Student Work Readiness (Y), the mediating role of Student Motivation, and the moderating and direct effects of Industry Relevance (M). A quantitative explanatory survey design was employed with total sampling involving 350 students at vocational high schools in Indonesia. Data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) via SmartPLS 4. All seven hypotheses were supported: Teacher Competency (β = 0.207, p = 0.000) and Learning Facilities (β = 0.211, p = 0.000) significantly predicted Student Motivation; Teacher Competency (β = 0.223), Learning Facilities (β = 0.270), and Student Motivation (β = 0.246) exerted significant direct effects on Work Readiness; Student Motivation mediated X1→X3→Y (β = 0.051) and X2→X3→Y (β = 0.052); Industry Relevance moderated Learning Facilities and Work Readiness (β = 0.151, p = 0.001); and Industry Relevance exerted a significant negative direct effect on self-assessed Work Readiness (β = −0.167, p = 0.001), interpreted as a perception gap mechanism. R² = 0.280 for Student Work Readiness. These findings provide evidence-based guidance for policymakers and school leaders to improve vocational education quality and graduate employability in Indonesia.

Abstract

This study aims to analyze the application of the Logic Model and Theory-Based Evaluation in evaluating educational programs at Vocational High Schools (SMK), as well as to identify the advantages, limitations, and effectiveness of both approaches. The method used is a Systematic Literature Review (SLR) referring to PRISMA guidelines. Literature searches were conducted through scientific databases with a publication range from 2019 to 2026. From the selection process, 15 articles that met the inclusion criteria were obtained and analyzed qualitatively using a narrative synthesis. The research results indicate that the Logic Model approach is effective in mapping program structures systematically through the relationships between inputs, processes, outputs, and outcomes, making it easier to understand program flow and result achievements. Meanwhile, Theory-Based Evaluation is superior in explaining the mechanisms of change and the cause-and-effect relationships underlying program success. Nevertheless, this approach has a higher level of complexity and requires more in-depth data. The conclusion of this research shows that there is no single approach that is entirely superior, so the integration of Logic Model and Theory-Based Evaluation becomes the most effective strategy in producing a comprehensive, systematic, and evidence-based program evaluation. This integrative approach is recommended to improve the quality of educational program evaluations in vocational high schools (SMK).

Abstract

The advancement of technology demands learning media that are more engaging and interactive. In the Power Transmission Systems course, instruction is still dominated by lectures, resulting in suboptimal student comprehension. This study aims to examine the effectiveness of a differential tutorial video as a learning medium. The research employed a pre-experimental one-group pretest–posttest design involving 30 Automotive Engineering students. A test instrument was administered before and after the intervention. Normality tests showed that pretest data were normally distributed, while posttest data were not, leading to the use of the Wilcoxon Signed Rank test. The results indicated an improvement in learning outcomes, with 30 positive ranks. A Z-value of –4.798 and p = 0.000 confirmed a significant difference. The effect size of 0.876 indicated a very strong impact. Overall, the tutorial video proved effective in enhancing students’ understanding of differential concepts through visual and auditory stimulation.Keywords: Video Tutorial, Differential, Learning Outcomes, Learning Media, Power Transmission System
