This study aims to improve the critical thinking skills of class X Multimedia students at Vocational High School in Jetis Yogyakarta. The method used in this research is the ADDIE development model. The test used in this study is a description test. The selection of the test form is based on the characteristics of the material and minimizes the guessing factor. The analysis was carried out using descriptive analysis to see the differences in students’ critical thinking skills in the control and experimental classes. The results of data analysis are typically distributed. This can be seen from the significant value in the control and experimental classes, greater than 0.05.
