IMPLEMENTASI METODE DEMONSTRASI INTERAKTIF MENGGUNAKAN GOOGLE SITES TERHADAP PENINGKATAN HASIL BELAJAR GAMBAR AUTOCAD SISWA KELAS X DPIB SMK NEGERI 2 SURABAYA

IMPLEMENTING INTERACTIVE DEMONSTRATION METHOD WITH GOOGLE SITES TO ENHANCE AUTOCAD DRAWING LEARNING OUTCOMES OF GRADE X DPIB STUDENTS AT SMK NEGERI 2 SURABAYA

Keterbatasan penggunaan media dan metode pembelajaran yang interaktif pada materi gambar AutoCAD menyebabkan siswa mengalami kesulitan dalam belajar mandiri di luar jam pelajaran. Penelitian ini bertujuan untuk menganalisis perbedaan hasil belajar praktik gambar AutoCAD antar kelas yang menerapkan metode demonstrasi interaktif yang didukung dengan media digital Google Sites dan kelas tanpa dukungan media digital, serta mendeskripsikan keterlaksanaan pembelajaran dan respon siswa. Metode penelitian yang digunakan adalah kuasi eksperimen dengan desain posttest only nonequivalent control group. Penelitian dilaksanakan di SMK Negeri 2 Surabaya pada tahun ajaran 2025/2026 dengan sampel dua kelas X DPIB, yaitu kelas eksperimen (n = 24) dan kelas kontrol (n efektif praktik = 27). Data dikumpulkan melalui posttest menggunakan rubrik penilaian, lembar observasi dan angket respon siswa dengan skala likert sebanyak 25 butir. Analisis data dilakukan menggunakan statistik deskriptif dan uji beda Welch t-test, dan hasil penelitian menunjukkan bahwa rata-rata nilai posttest praktik kelas eksperimen lebih tinggi (M = 97,00, SD = 3,401) dibandingkan kelas kontrol (M = 89,89, SD = 9,254) dan berbeda signifikan secara statistik (t(33,623) = −3,720, p < 0,001) dengan ukuran Hedges’ g = 0,98. Keterlaksanaan pembelajaran pada kelas eksperimen mencapai 100% pada setiap pertemuan, dan respon siswa berada pada kategori positif (M = 3,92). Simpulan penelitian ini menunjukkan bahwa penerapan metode demonstrasi interaktif didukung dengan media Google Sites efektif dalam meningkatkan hasil belajar praktik gambar AutoCAD.

The integration of interactive learning media in AutoCAD instruction has not been optimal, which may hinder students’ independent learning outside classroom hours. This study aimed to examine differences in AutoCAD practical learning outcomes between classes implementing an interactive demonstration method supported by Google Sites and classes without digital media support, as well as to describe learning implementation and students’ responses. A quasi experimental study with a posttest-only nonequivalent control group design was employed. The research was conducted at SMK Negeri 2 Surabaya in the 2025/2026 academic year involving two Grade X DPIB classes: an experimental class (n = 24) and a control class (effective n = 27). Data were collected through a practical posttest assessed using a scoring rubric, observation sheets, and a 25-item Likert-scale student response questionnaire. Data were analyzed using descriptive statistics and Welch’s t-test. The results showed that the experimental class achieved higher practical learning outcomes (M = 97.00, SD = 3.401) than the control class (M = 89.89, SD = 9.254), with a statistically significant difference (t(33.623) = −3.720, p < 0.001) and a large effect size (Hedges’ g = 0.98). Learning implementation reached 100% at each meeting, and students’ responses were categorized as positive (M = 3.92). These findings indicate that the interactive demonstration method supported by Google Sites is effective in improving students’ AutoCAD practical learning outcomes.
