Abstrak

The aim of the study is to describe the effectiveness of students in solving critical thinking ability test questions on trigonometric function material at XIth class students of SMA Al Ma'shum in 2024/2025 Academic Year. This research belongs to descriptive qualitative. The subjects of this study are  XI-1 students of SMA Al Ma'shum consist of 30 students. The sample determination is carried out using a purposive sampling technique. The research instrument used is in the form of 5 descriptive questions containing indicators of critical thinking ability. Based on the results of data processing, it is obtained that 8 students its around 27% are in "very good" category for they are able to complete the four indicators of mathematical critical thinking skills very well, 16 students it is around 53%  are in the "good" category for they are able to complete the four indicators of mathematical critical thinking skills well expect in their writing in complete and 6 students it is around 20% belong to  "quite good" category for  they are not able to meet the indicators of critical thinking skills. Thus, the effectiveness of the Missouri Mathematics Project learning model based on the Geogebra application is obtained on critical thinking skills in the trigonometric function material.
