Abstract

Analytical thinking is an ability that needs to be taught in physics learning. However, the results of pre-observation indicate that this ability is still not optimally developed in the learning process. The objective of this study is to find a way to increase analytical thinking ability through the implementation of problem-based learning model on global warming topic. The population of this one-group pre-test post-test quasi experiment research is the student on one senior high school in Cimahi with 31 students as a purposive sample. Seven questions in essay test of analytic thinking ability are used as instruments on this study. The result of qualitative research through analysis of variation and trend of students answers meanwhile quantitative results seen through the normalized gain value indicates an increase in analytical thinking ability. This study has reviewed the way students answer tests of analytical thinking skills on global warming topic by looking at students ability on differentiating, organizing, and attributing aspects so as to gain an analytical thinking ability capability on global warming topic of 0.44 for differentiating aspect, 0.43 for organizing aspect, and 0,39 for attributing aspect. This study has found a way that is capable to improve analytical thinking skills.
