The Experiment of Heat Matter Based on Scientific Inquiry in Senior High School

Abstract

This study aims to determine (1) whether the science process skills of students who are taught with the scientific inquiry model are better than students who are taught using conventional learning, (2) whether the critical thinking skills of students who are taught with the scientific inquiry model are better than in students who are taught with conventional learning. This type of research is a quasi-experiment with two groups pretest-posttest design. Sampling was carried out by means of cluster random sampling by taking two classes from three classes, namely class XI IPA-3 as the experimental class, amounting to 30 people and class XI IPA-1 as the control class, amounting to 31 people. The instruments used were tests and non-tests in which science process skills were in the form of student worksheets and critical thinking skills were in the form of essay questions consisting of 5 validated questions. Hypothesis testing using different test (t-test). Based on the results of the study, it was concluded that: (1) the science process skills of students who were taught with the scientific inquiry model were better than those who were taught using conventional learning, (2) the critical thinking skills of students who were taught with the scientific inquiry model were better than in students who are taught with conventional learning.
