Abstract

Vocational education (VE) is one of the institutions that must answer environmental problems by providing green job skills to its students. However, VE in Indonesia still experience various obstacles in providing this provision, so the aim of this research aims to analyze the extent of the level of green skills (GS) in teachers and students in this country, which includes the dimensions of cognitive, interpersonal and intrapersonal competence as an illustration for developing a priority scale for improvement. In addition, examining the differences and correlations between dimensions and the contribution of dimensions to GS as a whole is an additional goal. The survey method was carried out using a generic GS questionnaire instrument in VE that have Adiwiyata status. Data were analyzed using three stages: descriptive analysis, ANOVA-post hoc Tukey test, and path analysis. As a result, students’ GS still show a low category, while teachers get a high category. Between dimensions show no significant differences. Finally, all competencies have a significant relationship and can construct overall GS. These results indicate that there is still a need to strengthen teacher competencies in GS-based learning management and strengthen collaboration with all levels of society.

Abstract

The large number of graduates who lack the skills needed for the workplace makes it difficult for them to find employment. This study aims to analyze the influence of teachers, technology, and social capital in preparing vocational school graduates for their first jobs. Participants came from five districts in Yogyakarta, including state and private VHS with engineering expertise, including 25 teachers and 99 students. The research steps involve conducting literature reviews, focus group discussions, and data collection via questionnaires. The results show that: (1) the stability of choosing a career that is in line with their education for graduates who study further is better than graduates who work or are entrepreneurs; (2) the measurement model showed valid and reliable results: outer loading (0.702 -0.967), AVE ³ 0.5, Cronbach's alpha ³ 0.7, Fornell-Larcker criterion, and HTMT ratio. The structural model using the SRMR is 0.078 (good fit); (3) With p-value 0.000 (sig < 0.05), there is direct significant influence between TCR -> TGR (f2 0.897), TCR -> SCR (f2 0.638) with large effect, and TCR -> STWT (f2 0.310), TGR -> STWT (f2 0.189), SCR -> STWT (f2 0.267) with medium effect and the indirect influence (TCR -> STWT), which is mediated by TGR and SCR. The role of the teacher (TCR) has a significant impact on optimizing the role of technology (TGR) and social capital (SCR) in the STWT effectivity. The role of teachers, technology, and social capital all have significant and medium effects on the STWT smoothness. This is in line with the concept of Industry 5.0, specifically integration. Education in the Industry 5.0 era is dependent not just on the contributors' roles but also on integration.

Abstract

As technology continues to evolve, the gap between those who have grown up with technology (digital natives) and those who have not (digital immigrants) continues to widen. Therefore, this research aims to analyze the comparison of students learning outcomes taught by two different groups of teachers from different generation (digital native and digital immigrant). The subjects of this research were 10th-grade students in the Department of Computer and Network Engineering at Vocational High School. The total of the research respondents were 60 students. This research was using a quantitative approach with a comparative method. The data collected was the form of a questionnaire and a summary of the scores in the last semester. The results of the independent sample t-test obtained a Sig. (2-tailed) value of 0.065 > 0.05, so the decision making in the Independent Sample t-test, concluded that the null hypothesis (Ha) was accepted and the alternative hypothesis (Ha) rejected. Ho is a hypothesis which states that there is no correlation or influence between variables and other variables, while Ha is a hypothesis which states that there is a correlation or influence between variables and other variables. Based on the research result, it means that there is no difference in learning outcomes between students taught by digital immigrant teacher and digital native teacher. This research proves that digital native teachers and digital immigrant teachers are equally qualified.

Abstract

The fundamental problem in implementing education at the education level is that the learning process is generally too oriented to mastery of subject matter, not to the substance, meaning, or value it contains. This study aims to analyze the success of using visual-based interactive media or image media in science learning. This type of research is an actual experiment with a quantitative approach. The subjects in this study were 50 students consisting of 2 separate classes, the number of female students was 30, and the number of male students was 20. The method of data collection in this study used student learning outcomes pre-test and post-test. The instrument used is a test of learning outcomes and student response questionnaires. The technique used to analyze the data is the descriptive qualitative and quantitative analysis and inferential statistics. The results showed that the average score of learning science after using visual-based interactive learning media was 75.93, with a standard deviation of 16.19. The lowest score for students is 40, and the highest score is 99. Visual-based interactive media is effectively used to improve student learning outcomes in science. The research implication is that visual-based interactive media can be used by teachers in teaching so that they can help students learn.
