Abstract

Strengthening career choices for vocational students is essential in preparing them to enter the world of work. Many studies highlighted the importance of career choices that are by the areas of expertise for vocational students and even examine the mechanism for strengthening their career choices. However, limited studies still focused on testing models for forming career choices by involving social support, career self-efficacy, and vocational identity in an integrative manner. Therefore, this study investigated the model of developing student career choices by applying for social support, career self-efficacy, and vocational identity. This study used structural equation modelling (SEM) analysis with Amos 18 software. The study results revealed that social support, career self-efficacy, and vocational identity factors directly influence vocational students’ career choices. In addition, career self-efficacy mediates the effect of social support on career choice. Finally, vocational identity moderates the interaction of the independent variables (social support and career self-efficacy) and the dependent variable (career choice). The results of this study provided important implications for lecturers to implement learning strategies that aim to strengthen vocational students’ career choices.

Abstract

This study aims to (1) Develop a work-based learning-based industrial practicum platform; (2) Know the feasibility of a work-based learning-based industrial practicum platform; and (3) Know whether there is an effectiveness of student learning with a work-based learning-based industrial practicum platform. This type of research is Research and Development (R&D) with the Four-D model, and the research subjects are class C students as an experimental class with a total of 21 students and class B students as a control class with a total of 22 students. Data collection uses a questionnaire method to determine the feasibility of the media used for research and written test questions in the form of multiple choice with a total of 20 questions. The data analysis test used a normality test, homogeneity test, and t-test. The research data showed that: (1) The procedure for developing practical learning media based on work-based learning includes the defining stage, planning stage, development stage, and dissemination stage; (2) Work-based learning media is feasible to use as a learning media in light vehicle electrical maintenance subjects. This can be proven from the validation results of media expert lecturers who showed 82.50% of the score indicating valid criteria. Validation by material expert lecturers showed 78.75% of the score obtained, indicating quite valid criteria; and (3) The t-test results (t-count = 6.021 and p = 0.000) prove that the work-based learning-based practicum platform made is effective for improving student learning outcomes. This is shown through the response of trial students, which includes small group trials, obtaining 77%, which includes five students, and large group trials, obtaining 80.50%, which includes 15 students. The normality test obtained p = 0.059 in the control class and p = 0.115 in the experimental class because p> 0.05 indicates that both groups are normally distributed. Through the homogeneity test, F count = 0.762 with p = 0.388 because p > 0.05, the two groups have homogeneous variants. Thus, the industrial platform practice based on work-based learning can improve student learning outcomes.

Abstract

This study examines the effectiveness of a deep learning–based assessment system in vocational education, focusing on its implementation at SMK Negeri 8 Purworejo. To build a strong evidence base, the research first conducted a meta-analysis of earlier studies on automated deep learning assessment systems, selecting only those that used deep learning for performance-based evaluation, reported measurable accuracy or efficiency outcomes, and aligned with vocational or practical task contexts. The empirical phase tested a prototype system designed for productive Teknik Kendaraan Ringan (TKR) subjects, particularly for evaluating engine tune-up, component inspection, and basic troubleshooting practices. The system utilized video and image-based deep learning models to analyze student performance during hands-on activities. Data were collected from learning outcome documents, teacher interviews, student perception questionnaires, and observations of assessment duration. The results show that the deep learning–based system improves scoring precision, shortens evaluation time, and is positively received by both teachers and students. These practical gains support the meta-analytic findings and highlight the system’s potential to automate aspects of vocational assessment that were previously difficult to evaluate objectively. The study’s contribution lies in combining meta-analysis with real classroom implementation, offering a meaningful step toward AI-driven adaptive assessment in vocational education.

Abstract

As a vocational automotive teacher from SMK Muhammadiyah Larangan, the authors often find chapter trials of Grade XI students (TKR) they have had trouble memorizing the correct sequence of stages tuning?motors for eg 2010 Toyota Avanza EFI engine, especially in determining the function TPS, MAP and IACV. A single live example from the teacher is often not enough: students?might miss some crucial part of it while taking notes, or be too shy to ask questions when they don’t understand something. To address this problem, the researcher used a classroom action research with 12 minute video?instructional media using smartphone creations and Avanza engine 2010 in school. Sixty Grade XI TKR students were selected for this study, divided into an Experimental Group (video learning method) and a Control Group (traditional demonstration method). The results showed: Mean of Experimental group: 85.0, average of the control group : 67.3. A total of 83.3% of the experimental group received marks for the category of Excellent, while the control group received 0%. The result of the independent t-test showed that there is a significant difference between the means of the two groups, since t(58) = 8.21 The aforementioned findings prove the effect of the use of cheap instructional videos prepared by lecturers to address the issue of resource equality for better access to independent learning for the students, which lies squarely within the principle of autonomy of the students under the Merdeka Curriculum of Indonesia.
