Abstract

Vocational education in Indonesia faces challenges in producing graduates with technical competencies aligned with modern industry needs, particularly in workshop practice learning that remains instructive without considering social aspects and collaborative interactions. This research aims to analyze the implementation of lathe machine workshop practices through Vygotsky's social constructivism perspective at SMK Negeri 2 Karanganyar. Qualitative research methods with case study design were used to explore the implementation of Zone of Proximal Development concepts, scaffolding, and social interaction in practical learning. Data were collected through semi-structured interviews with mechanical engineering teachers and analyzed using thematic analysis techniques. Research results show that students' knowledge construction is realized through structured social interaction, instructors' role as more knowledgeable others with peer tutoring systems, gradual scaffolding implementation through demonstration and physical-symbolic tool mediation, and SMK's socio-cultural context supporting collaborative practice communities. This research concludes that Vygotsky's social constructivism theory effectively enhances students' activity, mutual assistance ability, self-confidence, and independence in lathe machine workshop practices.

Abstract

This quasi-experimental research examines the impact of Google Classroom integration on academic performance enhancement among grade XI students studying lathe machining technology at SMK Negeri 2 Karanganyar. The study utilized a single-group pretest-posttest methodology with purposive sampling involving 35 vocational education participants across an eight-week implementation phase. Data gathering employed a validated assessment tool containing 40 items (Cronbach's α = 0.951) designed to evaluate theoretical comprehension in lathe machining technology. Statistical examination indicated substantial enhancement in academic achievement following Google Classroom integration, demonstrating mean score progression from 85.57 (SD = 2.963) to 88.37 (SD = 2.808). The Wilcoxon Signed Ranks Test confirmed statistically meaningful variations (Z = -4.705, p < 0.05) between initial and final assessments, with 88.6% of subjects demonstrating academic progress. The platform's success stems from improved student participation, adaptable learning access, individualized educational experiences, and immediate feedback systems. These results provide empirical validation for digital learning management platform effectiveness within vocational educational settings, especially for technical disciplines requiring theoretical knowledge and practical skill integration. This investigation offers evidence-based guidance for enhancing technology-integrated learning environments in vocational educational institutions.
