PENINGKATAN HASIL BELAJAR ELEKTRONIKA DASAR II MELALUI PENERAPAN MODEL PEMBELAJARAN PROBLEM SOLVING LABORATORY

Abstract

Penelitian ini bertujuan untuk mengetahui peningkatan hasil belajar siswa SMP dengan pendekatan keterampilan proses pada pokok bahasan suhu dan pemuaian. Penelitian dilaksanakan dengan metode pre-post eksperimen tanpa kendali. Pre dan pos tes dilakukan untuk melihat peningkatan pemahaman konsep siswa. Pengamatan keterampilan dan sikap ilmiah dilakukan pada awal dan akhir kegiatan laboratorium berbasis inkuiri. Data penelitian diambil sebelum percobaan, selama percobaan, dan setelah percobaan. Hasil belajar pretes pemahaman konsep diperoleh rata-rata 51%, postes 61,73%, dan gain sebesar 0,219 (low-gain). Hasil belajar keterampilan proses, pengamatan awal diperoleh rata-rata 54%, pengamatan akhir 76%, dan gain sebesar 0,478 (medium-gain). Hasil pengamatan sikap ilmiah awal siswa rata-rata 55%, pengamatan akhir 67%, dan gain sebesar 0,267 (low-gain). Jadi hasil belajar siswa pada penelitian ini mengalami peningkatan.

 

The research aimed to observe the improvement of junior high Scholl students in learning on temperature and expansion by process skill approach. Uncontrolled pre-post experiment method was used in this study. Pre and post test was used to obtain the student's understanding. The observation of skills and scientific attitudes was done on the beginning and at the end of each inquiry based laboratory activity. The data extracted from beginning, during and after lab's activity. The achievements in concept understanding yield the value of 51 % for pre test  and  61.73%  for post test  thus gain the gain is 0.219 (low gain). The achievements in process skills end up with the value of 54 % for initials and 76% for the final's observations give the gain of 0.478 (medium-gain). The observations in scientific attitude give the average value 55% at the beginning and 67% at the end, so the gain is 0,267. Overall conclusion, the student's achievement is improved.
