Abstract

This research is motivated by the low critical thinking skills of class VII A Junior High School SMART Ekselensia students on environmental pollution material. Preliminary data shows that there are eleven people or sixty-nine percent of the difficulty in having critical thinking skills with a score of 60.0 in learning. One of the efforts to overcome these problems is to use learning media which is expected to encourage and bridge critical thinking skills. The purpose of this research is to increase critical thinking skills by using eco-enzyme product monotangray media. The research was conducted through classroom action consisting of two cycles, each consisting of two meetings. Methods of data collection using tests, observations and questionnaires. The research instrument used was a written test sheet, an observation sheet for observing student learning activities, observing teacher teaching activities. The data were analyzed descriptively quantitatively. The results showed an increase in critical thinking ability by 18 points from 68 in cycle 1 to 86 in cycle 2, thus it can be concluded that learning with eco-enzyme product monotangray media can improve students’ critical thinking skills. Based on the results of this study, it is recommended for other science teachers to use eco-enzyme-making media in learning the topic of environmental pollution that is adapted to the conditions and character of the class.
