摘要：This study aims to apply the Curious Note Program (CNP) learning model to improve students' critical thinking skills. This type of research is pre-experimental using one group pre-test post-test design. The population taken was class X MIPA SMAN 1 Wonoayu with two classes as samples, namely class X MIPA 1 and X MIPA 2. The sample used was a simple random sampling technique with equal opportunities given and taken randomly. The research instrument for implementation was in the form of observation sheets and tests based on questions with indicators of critical thinking. Techniques in analyzing the data used were quantitative descriptive for the implementation of learning, normality test to test normally distributed categories, homogeneity test to test homogeneity in both classes, paired t-test to compare pretest and post-test values, and n-gain to determine the increase in critical thinking skills. The conclusion of this study is that the implementation of the Curious Note Program (CNP) learning model is categorized as very good and can improve critical thinking skills in the moderate category in both classes.
