<![CDATA[The effectiveness of learning is said to be successful if all learning can be fulfilled. One of them is learning motivation. Learning that can increase the effectiveness of learning and student motivation towards critical thinking skills is electronic learning with the google classroom application. E-learning can measure students' motivation to learn and their critical thinking skills. Students are considered successful when they achieve their learning goals. But in reality, students have not shown motivation and critical thinking skills. This is what makes learning activities less effective and efficient. Students tend to be lazy to think and express their opinions. During the learning process, students need to be motivated to be interested in learning, thinking and understanding the material. It is the responsibility of the lecturer to always innovate in the learning process in order to stimulate motivation and critical thinking skills. The purpose of this study was to determine whether there was an effect of learning effectiveness and motivation using google classroom on critical thinking skills in educational research methods courses. This type of research is a quasi-experimental research (quasi-experimental). The design used is the non-equivalent group design.
