Abstract

Penelitian ini bertujuan untuk mengetahui perbedaan hasil belajar kognitif siswa antara penerapan model Discovery Learning dan Direct Instruction pada mata pelajaran Dasar-Dasar Teknik Pengelasan dan Fabrikasi Logam kelas X SMK Negeri 1 Kota Bekasi. Penelitian menggunakan pendekatan kuantitatif dengan metode eksperimen semu (Quasi Experiment) dan desain Nonequivalent Control Group Design. Subjek penelitian terdiri atas dua kelas, masing-masing berjumlah 37 siswa, yaitu kelas yang diajar menggunakan model Discovery Learning dan kelas yang diajar menggunakan model Direct Instruction. Instrumen penelitian berupa tes hasil belajar kognitif berbentuk pilihan ganda yang telah melalui uji validitas, reliabilitas, tingkat kesukaran, dan daya pembeda. Data dikumpulkan melalui Pretest dan Posttest, kemudian dianalisis menggunakan statistik deskriptif, uji prasyarat (uji normalitas dan homogenitas), uji Independent Sample T-Test, serta analisis N-Gain. Hasil penelitian menunjukkan bahwa rata-rata skor Posttest siswa pada kelas Discovery Learning sebesar 87,57, lebih tinggi dibandingkan kelas Direct Instruction sebesar 64,86. Hasil uji Independent Sample T-Test menunjukkan nilai signifikansi 0,000 < 0,05, sehingga terdapat perbedaan hasil belajar kognitif yang signifikan antara kedua kelas. Analisis N-Gain menunjukkan bahwa kelas Discovery Learning memiliki nilai rata-rata N-Gain sebesar 0,7339 (kategori tinggi), sedangkan kelas Direct Instruction memiliki nilai rata-rata N-Gain sebesar 0,2972 (kategori rendah). Berdasarkan hasil tersebut, dapat disimpulkan bahwa terdapat perbedaan hasil belajar kognitif dan tingkat peningkatan hasil belajar antara siswa yang diajar menggunakan model Discovery Learning dan Direct Instruction pada mata pelajaran Dasar-Dasar Teknik Pengelasan dan Fabrikasi Logam. ****** This study aims to determine the differences in students' cognitive learning outcomes between the application of the Discovery Learning model and Direct Instruction in the subject of Fundamentals of Welding and Metal Fabrication in class X at SMK Negeri 1 Kota Bekasi. The research used a quantitative approach with a quasi-experimental method and a Nonequivalent Control Group Design. The research subjects consisted of two classes, each with 37 students, namely the class taught using the Discovery Learning model and the class taught using the Direct Instruction model. The research instrument was a multiple-choice cognitive learning test that had undergone validity, reliability, difficulty level, and discrimination power tests. Data were collected through Pretest and Posttest, then analyzed using descriptive statistics, prerequisite tests (normality and homogeneity tests), Independent Sample T-Test, and N-Gain analysis. The results showed that the average Posttest score of students in the Discovery Learning class was 87.57, higher than that of the Direct Instruction class, which was 64.86. The Independent Sample T-Test showed a significance value of 0.000 < 0.05, indicating a significant difference in cognitive learning outcomes between the two classes. The N-Gain analysis showed that the Discovery Learning class had an average N-Gain value of 0.7339 (high category), while the Direct Instruction class had an average NGain value of 0.2972 (low category). Based on these results, it can be concluded that there is a difference in cognitive learning outcomes and the level of learning improvement between students taught using the Discovery Learning and Direct Instruction models in the subject of Fundamentals of Welding and Metal Fabrication
