EFEK MODEL PEMBELAJARAN INQUIRY TRAINING BERBANTUAN SIMULASI PhET TERHADAP KEMAMPUAN BERFIKIR KRITIS SISWA SMA NEGERI 1 MEDAN T.A 2018/2019

Abstract

ABSTRAK

Penelitian ini bertujuan mengetahui kemampuan berfikir kritis siswa yang diajarkan dengan model pembelajaran inquiry training berbantuan simulasi (Physics Education Tecnology) PhET, dan mengetahui aktivitas kemampuan berfikir kritis siswa dengan model pembelajaran inquiry training berbantuan simulasi PhET. Jenis penelitian ini merupakan quasi experiment. Desain penelitian ini two group pretest-postest. Populasi dalam penelitian ini seluruh siswa kelas X yang terdiri dari sepuluh kelas MIA. Sampel penelitian ini  yaitu kelas XMIA-2sebagai kelas eksperimen dan kelas X MIA-3 sebagai kelas kontrol yang masing-masing berjumlah 36 orang yang ditentukan dengan cara Cluster Random Sampling. Instrumen yang digunakan adalah tes kemampuan berfikir kritis yang berjumlah 10 soal dalam bentuk essay test. Hasil analisis data menggunakan uji t diperoleh nilai rata-rata pretest kelas eksperimen dan kelas kontrol memiliki kemampuan awal sama. Diberikan perlakuan berbeda, kelas eksperimen dengan model pembelajaran inquiry training berbantuan simulasi PhET dan konvensional pada kelas kontrol maka diperoleh nilai rata-rata postes kelas eksperimen 89,5 dan kelas kontrol 87,83. Berdasarkan hasil uji t diperoleh ada efek model inquiry training  berbantuan simulasi PhET terhadap kemampuan berfikir kritis siswa pada materi pokok gerak harmonik sederhana di kelas X Semester II SMA Negeri 1 Medan T.A 2018/2019 yang sejalan dengan meningkatnya aktivitas kemampuan berfikir kritis pada setiap pertemuan.

ABSTRACT

This study aims to determine the critical thinking skills of students taught with inquiry learning models assisted training (Physics Education Technology) PhET, and determine the activities of students' critical thinking skills with inquiry learning models assisted by PhET simulation training. This type of research is quasi experiment. The study design was two group pretest-posttest. The population in this study were all students in class X of ten MIA classes. The sample of this study was class X MIA-2 as the experimental class and class X MIA-3 as the control class, each of which amounted to 36 people determined by Cluster Random Sampling. The instrument used was a test of critical thinking skills which numbered 10 questions in the form of an essay test. The results of data analysis using the t test obtained the average value of the experimental class pretest and the control class had the same initial ability. Different treatments were given, the experimental class with the inquiry learning training model assisted with PhET simulation and conventional in the control class, the mean scores of the experimental class posttest 89.5 and the control class 87.83. Based on the results of the t test, there is an effect of the inquiry training model assisted by PhET simulation on students' critical thinking skills in the subject matter of simple harmonic motion in class X Semester II SMA Negeri 1 Medan T.A 2018/2019 which is in line with the increasing activity of critical thinking skills at each meeting.
