The purpose of this study is to analyze the feasibility and practicality of CTL-approched student activity worksheet in environmental change material as one of the teaching materials in the learning process. The research method used in this study is a modified Research and Development (RnD) by Sugiyono (2015). The instruments used in this study are validation sheet by material and media experts, student activity worksheet readability questionnaire sheet by students, practicality questionnaire sheet by teacher & students, and interview guidelines. The validity of the material obtains a score of 82.14% with very Feasible  criteria and it shows the suitability of the material presented with the CTL approach. The validity of the media obtains a score of 94.6% with very valid criteria and it shows the suitability of the graphic and language aspects. The results of the readability test by students shows a score of 75.2% with Feasible criteria. The result of the practicality assessment of student activity worksheet by teacher  reaches a score of 95.83% with very practical criteria and by students reachs a score of 76.23% with practical criteria. Based on the research results, it can be concluded that the developed-CTL-approched student activity worksheet is very feasible and practical to use in learning process.
