Abstract

Abstrac Critical thinking skills are abilities that must be possessed in life in the 21st century. Learning in higher education must be able to train students to be ready to live life in the future by having critical thinking skills. Based on several research results, one of the learning models that is able to train critical thinking skills is project-based learning.

This research is a pre-experimental study with a one group pre-test post-test design, conducted on a sample of 36 students of Biology Education Study Program, Muhammadiyah University of Surabaya. To find out the increase in critical thinking skills after carrying out project-based learning, data analysis of pre-test and post-test results was used using normalized gain. The results of the study show that there is an increase in critical thinking skills after implementing project-based learning in the moderate category
