Penggunaan discovery learning dan problem based learning terhadap hasil belajar siswa SMK

Abstract

Penelitian ini bertujuan untuk mengungkapkan: (1) peningkatan hasil belajar setelah digunakan pembelajaran Discovery Learning (DL) materi K3 Instalasi Listrik; (2) peningkatan hasil belajar setelah digunakan pembelajaran Problem-Based Learning (PBL); dan (3) perbedaan hasil belajar antara DL dan PBL jika kemampuan awal dan potensi akademik dikendalikan pada pembelajaran K3 Instalasi Listrik di SMK. Jenis penelitian menggunakan quasi experiment. Subjek penelitian yaitu kelompok kontrol dan eksperimen Program Keahlian Teknik Ketenagalistrikan SMKN3 Yogyakarta. Instrumen berupa soal pretest, posttest, dan TPA. Analisis data menggunakan Anakova. Hasil penelitian adalah hasil belajar siswa menggunakan DL dengan t=36.560, taraf signifikansi 0.000, dan gain score 0.410 termasuk kategori sedang. Hasil belajar siswa menggunakan PBL dengan t=42.038, taraf signifikansi 0.000, dan gain score 0.556 termasuk kategori sedang. Ada perbedaan hasil belajar antara DL dan PBL jika kemampuan awal dan potensi akademik dikendalikan pada materi K3 instalasi listrik di SMK dengan nilai F=13.018, taraf signifikansi 0.001, dan kontribusi kovarian 95.74%.

THE USE OF DISCOVERY LEARNING AND PROBLEM-BASED LEARNING ON THE LEARNING ACHIEVEMENT OF SMK STUDENTS

Abstract

This research aims to reveal the improvement of students’ learning achievement in work health and safety in electrical installation material taught using the Discovery Learning (DL); (2) the improvement of students’ learning achievement after the same material was given using the Problem-Based Learning (PBL); and (3) the difference in the learning achievement between the students taught using the two different models if students prior knowledge and practice grade are controlled. This research was quasi-experimental. The subjects consisted two groups of control and experimental Electrical Engineering Program SMK3 Yogyakarta. The instrument were pretest, posttest, and practice grade. Data were analyzed using the ANACOVA. The research findings reveal that t=36.560, significance level 0.000, and “gain score” 0.410 which can be interpreted as the medium category in mastering concepts of students in DL. The research findings reveal that t=42.038, significance level 0.000, and “gain score” 0.556 which can also be interpreted as the medium category in PBL. There is a difference between the use of two different models on learning achievement with r=0.539, F=13.018, significance level 0.001, and the covariance contribution of 95.74%.
