This classroom action research aims to improve students' problem-solving skills through the application of contextual learning. The subjects of the research were 36 students of class X-E7 of SMAN 1 Palu. This research was conducted in two cycles, each consisting of planning, action implementation, observation, and reflection. Data were collected through observation, problem-solving skills tests, and documentation of learning activities. The results of the study showed an increase in students' problem-solving skills from cycle I to cycle II. In cycle I, the percentage of Ngain was 16.09%, which indicated that it was still ineffective, while Ngain in cycle II increased to 33.4%, which was categorized as moderate. This increase indicates that the contextual learning approach is quite effective in helping students relate subject matter to real-life situations, so that they are more actively involved in the learning process and are able to solve problems more systematically.
