Abstract

Understanding welding defect analysis is a crucial competency in vocational welding education, especially in ensuring the quality and safety of welding outcomes. However, many students struggle to master this material due to the lack of interactive and adaptive learning media. This study aims to develop and implement an electronic module (e-module) to enhance student learning outcomes in Shielded Metal Arc Welding (SMAW) defect analysis at SMK N 5 Semarang. The research uses a Research and Development (R&D) approach based on the 4D model: Define, Design, Develop, and Disseminate. A one-group pre-test post-test design was used, involving 33 Grade XI Mechanical Engineering 2 students. The e-module was validated by experts and classified as "Valid" in terms of content, media, and assessments. Students' average scores increased from 40.61 in the pre-test to 78.64 in the post-test. Statistical analysis using the Wilcoxon Signed-Rank Test and paired t-test showed a significant difference (p < 0.001). The average N-Gain score was 0.63, indicating a moderate improvement. The results confirm that the e-module is both feasible and effective. It enhances students’ conceptual understanding and supports independent, technology-based learning aligned with the characteristics of digital-native learners.

Abstract

This study examines the contextual teaching and learning (CTL) model's effectiveness in improving cognitive learning outcomes of vocational education students. Using a pretest-posttest quasi-experimental design, this study involved 60 tenth-grade mechanical engineering students, divided equally into control and experimental groups. The experimental group received the CTL learning model treatment, while the control group used conventional learning methods. A 20-item multiple-choice test based on Bloom's Taxonomy was used to measure students' cognitive learning outcomes. Instrument validation showed good content validity (Aiken's V=0.714- 1.00) and obtained good reliability results as well (ICC=0.730). The experimental group received a higher average post-test score (89.17) compared to the control group (75.83), with the acquisition of N-Gain values in the experimental group (0.7427) and control group (0.4013), with statistical analysis showing a significant difference (p0.05). These findings indicate that CTL effectively improves basic understanding and critical thinking skills. This study supports the integration of CTL into vocational education systems aligned with international priorities of competency-based learning and workforce readiness. This study provides empirical evidence that CTL can improve learning outcomes and equip students with critical thinking skills.

Abstract

The problem with learning Occupational Health, Safety, and Environmental Protection (OHS-EP) and Industrial Work Culture is that most students show a lack of enthusiasm in participating in lessons and struggle to understand the teaching material, particularly in important aspects such as the application of OHS-EP procedures, the use of personal protective equipment (PPE), and understanding the principles of industrial work culture. This study aims to apply and analyze the feasibility and effectiveness of an Android-based E-Module to improve the cognitive abilities of vocational school students on the subjects of OHS-EP and Industrial Work Culture. The research follows the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). A pre-experimental method with a two-group pretest-posttest design was employed, comparing an experimental class and a control class consisting of 70 students. The results indicate that the assessment of the material, media, and test instruments for the E-Module is deemed suitable for use. Statistical analysis reveals a significant improvement in the experimental class compared to the control class after the intervention. The results of the N-Gain test show that the experimental class experienced a 53.4% improvement (moderate category), while the control class showed only a 21.5% improvement, indicating enhanced cognitive abilities among the students. This study emphasizes the positive impact of technology on education and reinforces the importance of innovative teaching methods to improve cognitive abilities in students.
